Trials with a duration of 6 to 13 28-day cycles provided safety data. In total, 2,501 women, aged 18 to 41 contributed 24,520 cycles of exposure. Common Adverse Reactions (≥ 2%): vaginitis (13.8%), headache (including migraine) (11.2%), mood changes (e.g., depression, mood swings, mood altered, depressed mood, affect lability) (6.4%), device-related events (e.g., expulsion/discomfort/foreign body sensation) (6.3%), nausea/vomiting (5.9%), vaginal discharge (5.7%), increased weight (4.9%), vaginal discomfort (4.0%), breast pain/discomfort/tenderness (3.8%), dysmenorrhea (3.5%), abdominal pain (3.2%), acne (2.4%), and decreased libido (2.0%). Adverse Reactions (≥ 1%) Leading to Study Discontinuation: 13.0% of the women discontinued from the clinical trials due to an adverse reaction; the most common adverse reactions leading to discontinuation were device-related events (2.7%), mood changes (1.7%), headache (including migraine) (1.5%) and vaginal symptoms (1.2%). Serious Adverse Reactions: deep vein thrombosis [see Warnings and Precautions (5.1) ] , anxiety, cholelithiasis, and vomiting. 6.2 Post-marketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 2). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to10 years of COC use. Figure 2: RR = relative risk; OR = odds ratio; HR = hazard ratio. “ever COC” are females with current or past COC use; “never COC use” are females that never used COCs. The following adverse reactions have been identified during post-approval use of EluRyng. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune system disorders: hypersensitivity reactions, including anaphylaxis and angioedema Nervous system disorders: stroke/cerebrovascular accident Vascular disorders: arterial events (including arterial thromboembolism and myocardial infarction), aggravation of varicose veins Skin and subcutaneous tissue disorders: urticaria, chloasma Reproductive system and breast disorders: penile disorders, including local reactions on penis (in male partners of women using EluRyng), galactorrhea General Disorders and Administration Site Conditions: device breakage (including with concomitant use of intravaginal antimycotic, antibiotic, and lubricant products) Injury, poisoning and procedural complications: vaginal injury (including associated pain, discomfort, and bleeding) associated with ring breakage 01

11 DESCRIPTION EluRyng (etonogestrel and ethinyl estradiol vaginal ring) is a non-biodegradable, flexible, transparent to translucent , colorless to almost colorless, combination contraceptive vaginal ring containing two active components, a progestin, etonogestrel (13-ethyl-17-hydroxy-11-methylene-18,19-dinor-17α-pregn-4-en-20-yn-3-one) and an estrogen, ethinyl estradiol, USP (19-nor-17α-pregna-1,3,5(10)-trien-20-yne-3,17-diol). When placed in the vagina, each ring releases on average 0.120 mg/day of etonogestrel and 0.015 mg/day of ethinyl estradiol, USP over a three-week period of use. EluRyng is made of ethylene vinylacetate copolymers (28% and 9% vinylacetate) and magnesium stearate and contains 11.7 mg etonogestrel and 2.7 mg ethinyl estradiol, USP. EluRyng is not made with natural rubber latex. EluRyng has an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. The molecular weights for etonogestrel and ethinyl estradiol, USP are 324.5 and 296.40, respectively. The structural formulas are as follows: formula

2 DOSAGE AND ADMINISTRATION One EluRyng is inserted in the vagina. The ring must remain in place continuously for three weeks, followed by a one-week ring-free interval. (2) 2.1 How to Use EluRyng To achieve maximum contraceptive effectiveness, EluRyng must be used as directed [see Dosage and Administration (2.2) ] . One EluRyng is inserted in the vagina. The ring is to remain in place continuously for three weeks. It is removed for a one-week break, during which a withdrawal bleed usually occurs. A new ring is inserted one week after the last ring was removed. The user can choose the insertion position that is most comfortable to her, for example, standing with one leg up, squatting, or lying down. The ring is to be compressed and inserted into the vagina. The exact position of EluRyng inside the vagina is not critical for its function. The vaginal ring must be inserted on the appropriate day and left in place for three consecutive weeks. This means that the ring should be removed three weeks later on the same day of the week as it was inserted and at about the same time. EluRyng can be removed by hooking the index finger under the forward rim or by grasping the rim between the index and middle finger and pulling it out. The used ring should be placed in the foil pouch and discarded in a waste receptacle out of the reach of children and pets (do not flush in toilet). After a one-week break, during which a withdrawal bleed usually occurs, a new ring is inserted on the same day of the week as it was inserted in the previous cycle. The withdrawal bleed usually starts on Day 2 to 3 after removal of the ring and may not have finished before the next ring is inserted. In order to maintain contraceptive effectiveness, the new ring must be inserted exactly one week after the previous one was removed even if menstrual bleeding has not finished. 2.2 How to Start Using EluRyng IMPORTANT: Consider the possibility of ovulation and conception prior to the first use of EluRyng . No Hormonal Contraceptive Use in the Preceding Cycle: The woman should insert EluRyng on the first day of her menstrual bleeding. EluRyng may also be started on Days 2 to 5 of the woman’s cycle, but in this case a barrier method, such as male condoms with spermicide, should be used for the first seven days of EluRyng use in the first cycle. Changing From a CHC: The woman may switch from her previous CHC on any day, but at the latest on the day following the usual hormone-free interval, if she has been using her hormonal method consistently and correctly, or if it is reasonably certain that she is not pregnant. Changing From a Progestin-Only Method (progestin-only pill [POP], Implant, or Injection or a Progestin-Releasing Intrauterine System [IUS]): The woman may switch from the POP on any day; instruct her to start using EluRyng on the day after she took her last POP. She should switch from an implant or the IUS on the day of its removal, and from an injectable on the day when the next injection would be due. In all of these cases, the woman should use an additional barrier method such as a male condom with spermicide, for the first seven days. Use After Abortion or Miscarriage: The woman may start using EluRyng within the first five days following a complete first trimester abortion or miscarriage, and she does not need to use an additional method of contraception. If use of EluRyng is not started within five days following a first trimester abortion or miscarriage, the woman should follow the instructions for “No Hormonal Contraceptive Use in the Preceding Cycle.” In the meantime, she should be advised to use a non-hormonal contraceptive method. Start EluRyng no earlier than four weeks after a second trimester abortion or miscarriage, due to the increased risk of thromboembolism [see Contraindications (4) and Warnings and Precautions (5.1) ]. Following Childbirth: The use of EluRyng may be initiated no sooner than four weeks postpartum in women who elect not to breastfeed, due to the increased risk of thromboembolism in the postpartum period [see Contraindications (4) and Warnings and Precautions (5.1) ]. Advise women who are breastfeeding not to use EluRyng but to use other forms of contraception until the child is weaned. If a woman begins using EluRyng postpartum, instruct her to use an additional method of contraception, such as male condoms with spermicide, for the first seven days. If she has not yet had a period, consider the possibility of ovulation and conception occurring prior to initiation of EluRyng. 2.3 Deviations from the Recommended Regimen To prevent loss of contraceptive efficacy, advise women not to deviate from the recommended regimen. EluRyng should be left in the vagina for a continuous period of three weeks. Advise women to regularly check for the presence of EluRyng in the vagina (for example, before and after intercourse). Inadvertent Removal or Expulsion EluRyng can be accidentally expelled, for example, while removing a tampon, during intercourse, or with straining during a bowel movement. EluRyng should be left in the vagina for a continuous period of three weeks. If the ring is accidentally expelled and is left outside of the vagina for less than three hours , contraceptive efficacy is not reduced. EluRyng can be rinsed with cool to lukewarm (not hot) water and reinserted as soon as possible, but at the latest within three hours. If EluRyng is lost, a new vaginal ring should be inserted and the regimen should be continued without alteration. If EluRyng is out of the vagina for more than three continuous hours: During Weeks 1 and 2: Contraceptive efficacy may be reduced. The woman should reinsert the ring as soon as she remembers. A barrier method such as male condoms with spermicides must be used until the ring has been used continuously for seven days. During Week 3: The woman should discard that ring. One of the following two options should be chosen: Insert a new ring immediately. Inserting a new ring will start the next three-week use period. The woman may not experience a withdrawal bleed from her previous cycle. However, breakthrough spotting or bleeding may occur. Insert a new ring no later than seven days from the time the previous ring was removed or expelled, during which time she may have a withdrawal bleed. This option should only be chosen if the ring was used continuously for at least seven days prior to inadvertent removal/expulsion. In either case, a barrier method such as male condoms with spermicides must be used until the new ring has been used continuously for seven days. If EluRyng was out of the vagina for an unknown amount of time, the possibility of pregnancy should be considered. A pregnancy test should be performed prior to inserting a new ring. Prolonged Ring-Free Interval If the ring-free interval has been extended beyond one week, consider the possibility of pregnancy, and an additional method of contraception, such as male condoms with spermicide, MUST be used until EluRyng has been used continuously for seven days. Prolonged Use of EluRyng If EluRyng has been left in place for up to one extra week (i.e., up to four weeks total), the woman will remain protected. EluRyng should be removed and the woman should insert a new ring after a one-week ring-free interval. If EluRyng has been left in place for longer than four weeks, instruct the woman to remove the ring, and rule out pregnancy. If pregnancy is ruled out, EluRyng may be restarted, and an additional method of contraception, such as male condoms with spermicide, MUST be used until a new EluRyng has been used continuously for seven days. Ring Breakage There have been reported cases of EluRyng disconnecting at the weld joint. This is not expected to affect the contraceptive effectiveness of EluRyng. In the event of a disconnected ring, vaginal discomfort or expulsion (slipping out) is more likely to occur. Vaginal injury associated with ring breakage has been reported [see Adverse Reactions (6.2) ] . If a woman discovers that her EluRyng has disconnected, she should discard the ring and replace it with a new ring. 2.4 In the Event of a Missed Menstrual Period If the woman has not adhered to the prescribed regimen (EluRyng has been out of the vagina for more than three hours or the preceding ring-free interval was extended beyond one week), consider the possibility of pregnancy at the time of the first missed period and discontinue EluRyng use if pregnancy is confirmed. If the woman has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy. If the woman has retained one EluRyng for longer than four weeks, rule out pregnancy. 2.5 Use with Other Vaginal Products EluRyng may interfere with the correct placement and position of certain female barrier methods such as a diaphragm, cervical cap or female condom. These methods are not recommended as back-up methods with EluRyng use. Pharmacokinetic data show that the use of tampons has no effect on the systemic absorption of the hormones released by EluRyng.

1 INDICATIONS AND USAGE FOR VAGINAL USE ONLY EluRyng™ is indicated for use by females of reproductive age to prevent pregnancy. EluRyng is an estrogen/progestin combination hormonal contraceptive (CHC) indicated for use by women to prevent pregnancy. (1)

10 OVERDOSAGE There have been no reports of serious ill effects from overdose of CHCs. Overdosage may cause withdrawal bleeding in females and nausea. If the ring breaks, it does not release a higher dose of hormones. In case of suspected overdose, all EluRyng rings should be removed and symptomatic treatment given.

7 DRUG INTERACTIONS Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. Drugs or herbal products that induce certain enzymes, such as CYP3A4, may decrease the effectiveness of CHCs or increase breakthrough bleeding. Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with CHCs. (7) 7.1 Effects of Other Drugs on CHCs Substances decreasing the plasma concentrations of CHCs and potentially diminishing the effectiveness of CHCs Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the plasma concentrations of CHCs and potentially diminish the effectiveness of CHCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include: phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampicin, topiramate, rifabutin, rufinamide, aprepitant, and products containing St. John's wort. Interactions between CHCs and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative non-hormonal method of contraception or a back-up method when enzyme inducers are used with EluRyng, and to continue back-up non-hormonal contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability. Note: EluRyng may interfere with the correct placement and position of certain female barrier methods such as a diaphragm or female condom. These methods are not recommended as back-up methods with EluRyng use [see Dosage and Administration (2.5) ] . The serum concentrations of etonogestrel and ethinyl estradiol were not affected by concomitant administration of oral amoxicillin or doxycycline in standard dosages during 10 days of antibiotic treatment. The effects of other antibiotics on etonogestrel or ethinyl estradiol concentrations have not been evaluated. Substances increasing the plasma concentrations of CHCs Co-administration of atorvastatin and certain CHCs containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20-25%. Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol concentrations, possibly by inhibition of conjugation. Concomitant administration of strong or moderate CYP3A4 inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase plasma estrogen and/or progestin concentrations. Co-administration of vaginal miconazole nitrate and EluRyng increases the serum concentrations of etonogestrel and ethinyl estradiol by up to 40% [see Clinical Pharmacology (12.3) ] . Human immunodeficiency virus (HIV) / Hepatitis C Virus (HCV) protease inhibitors and non­-nucleoside reverse transcriptase inhibitors Significant changes in the plasma concentrations of the estrogen and /or progestin have been noted in some cases of co-administration with HIV protease inhibitors (decrease [e.g., nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir] or increase [e.g., indinavir and atazanavir/ritonavir]) /HCV protease inhibitors (decrease [e.g., boceprevir and telaprevir]) or with non-nucleoside reverse transcriptase inhibitors (decrease [e.g., efavirenz, nevirapine] or increase [e.g., etravirine]). These changes may be clinically relevant in some cases. 7.2 Effects of CHCs on Other Drugs CHCs containing ethinyl estradiol may inhibit the metabolism of other compounds (e.g., cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole) and increase their plasma concentrations. CHCs have been shown to decrease plasma concentrations of acetaminophen, clofibric acid, morphine, salicylic acid and temazepam. A significant decrease in the plasma concentrations of lamotrigine has been shown, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid-binding globulin increase with use of CHCs. 7.3 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer EluRyng with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions (5.4) ] . 7.4 Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Combination hormonal contraceptives act by suppression of gonadotropins. Although the primary effect of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation). 12.3 Pharmacokinetics Absorption Etonogestrel: Etonogestrel released by EluRyng is rapidly absorbed. The bioavailability of etonogestrel after vaginal administration is approximately 100%. The serum etonogestrel and ethinyl estradiol concentrations observed during three weeks of EluRyng use are summarized in Table 2. Ethinyl estradiol: Ethinyl estradiol released by EluRyng is rapidly absorbed. The bioavailability of ethinyl estradiol after vaginal administration is approximately 56%, which is comparable to that with oral administration of ethinyl estradiol. The serum ethinyl estradiol concentrations observed during three weeks of EluRyng use are summarized in Table 2. Table 2: Mean (SD) Serum Etonogestrel and Ethinyl Estradiol Concentrations (n=16) 1 week 2 weeks 3 weeks etonogestrel (pg/mL) 1578 (408) 1476 (362) 1374 (328) ethinyl estradiol (pg/mL) 19.1 (4.5) 18.3 (4.3) 17.6 (4.3) The pharmacokinetic profile of etonogestrel and ethinyl estradiol during use of EluRyng is shown in Figure 3. Figure 3: Mean Serum Concentration-Time Profile of Etonogestrel and Ethinyl Estradiol during Three Weeks of EluRyng Use The pharmacokinetic parameters of etonogestrel and ethinyl estradiol were determined during one cycle of EluRyng use in 16 healthy female subjects and are summarized in Table 3.

The mean serum ethinyl estradiol concentration at the end of the fourth week of continuous use of EluRyng was 16.8 ± 4.6 pg/mL compared to a mean concentration range of 19.1 ± 4.5 to 17.6 ± 4.3 pg/mL at the end of weeks one to three. Distribution Etonogestrel: Etonogestrel is approximately 32% bound to sex hormone-binding globulin (SHBG) and approximately 66% bound to albumin in blood. Ethinyl estradiol: Ethinyl estradiol is highly but not specifically bound to serum albumin (98.5%) and induces an increase in the serum concentrations of SHBG. Metabolism In vitro data shows that both etonogestrel and ethinyl estradiol are metabolized in liver microsomes by the cytochrome P450 3A4 isoenzyme. Ethinyl estradiol is primarily metabolized by aromatic hydroxylation, but a wide variety of hydroxylated and methylated metabolites are formed. These are present as free metabolites and as sulfate and glucuronide conjugates. The hydroxylated ethinyl estradiol metabolites have weak estrogenic activity. The biological activity of etonogestrel metabolites is unknown. Excretion Etonogestrel and ethinyl estradiol are primarily eliminated in urine, bile and feces. Drug Interactions [See also Drug Interactions (7) .] The drug interactions of EluRyng were evaluated in several studies. A single-dose vaginal administration of an oil-based 1200-mg miconazole nitrate capsule increased the serum concentrations of etonogestrel and ethinyl estradiol by approximately 17% and 16%, respectively. Following multiple doses of 200 mg miconazole nitrate by vaginal suppository or vaginal cream, the mean serum concentrations of etonogestrel and ethinyl estradiol increased by up to 40%. A single-dose vaginal administration of 100-mg water-based nonoxynol-9 spermicide gel did not affect the serum concentrations of etonogestrel or ethinyl estradiol. The serum concentrations of etonogestrel and ethinyl estradiol were not affected by concomitant administration of oral amoxicillin or doxycycline in standard dosages during 10 days of antibiotic treatment. Tampon Use The use of tampons had no effect on serum concentrations of etonogestrel and ethinyl estradiol during use of EluRyng [see Dosage and Administration (2.5) ] . Figure 2

Instructions for Use EluRyng ™ (el’ue ring) (etonogestrel and ethinyl estradiol vaginal ring) Read these Instructions for Use before you start using EluRyng and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your treatment. How should I start using EluRyng? If you are not currently using hormonal birth control, you have 2 ways to start using EluRyng. Choose the best way for you: First Day Start: Insert EluRyng on the first day of your menstrual period. You will not need to use another birth control method since you are using EluRyng on the first day of your menstrual period. Day 2 to Day 5 Cycle Start: You may choose to start EluRyng on days 2 to 5 of your menstrual period. Make sure you also use an extra method of birth control (barrier method), such as male condoms with spermicide for the first 7 days of EluRyng use in the first cycle. If you are changing from a birth control pill or patch to EluRyng: If you have been using your birth control method correctly and are certain that you are not pregnant, you can change to EluRyng any day. Do not start EluRyng any later than the day you would start your next birth control pill or apply your patch. If you are changing from a progestin-only birth control method, such as a minipill, implant or injection or from an intrauterine system (IUS): You may switch from a minipill on any day. Start using EluRyng on the day that you would have taken your next minipill. You should switch from an implant or the IUS and start using EluRyng on the day that you remove the implant or IUS. You should switch from an injectable and start using EluRyng on the day when your next injection would be due. If you are changing from a minipill, implant or injection or from an intrauterine system (IUS), you should use an extra method of birth control, such as a male condom with spermicide during the first 7 days of using EluRyng. If you start using EluRyng after an abortion or miscarriage: Following a first trimester abortion or miscarriage: You may start EluRyng within 5 days following a first trimester abortion or miscarriage (the first 12 weeks of pregnancy). You do not need to use an additional birth control method . If you do not start EluRyng within 5 days after a first trimester abortion or miscarriage, use a non-hormonal birth control method, such as male condoms and spermicide, while you wait for your period to start. Begin EluRyng at the time of your next menstrual period. Count the first day of your menstrual period as “Day 1” and start EluRyng one of the following 2 ways below. First Day Start: Insert EluRyng on the first day of your menstrual period. You will not need to use another birth control method since you are using EluRyng on the first day of your menstrual period. Day 2 to Day 5 Cycle Start: You may choose to start EluRyng on Days 2 to 5 of your menstrual period. Make sure you also use an extra method of birth control (barrier method), such as male condoms with spermicide for the first 7 days of EluRyng use in the first cycle. Following a second trimester abortion or miscarriage: You may start using EluRyng no sooner than 4 weeks (28 days) after a second trimester abortion ( after the first 12 weeks of pregnancy). If you are starting EluRyng after childbirth: You may start using EluRyng no sooner than 4 weeks (28 days) after having a baby if you are not breastfeeding. If you have not gotten your menstrual period after childbirth, you should talk to your healthcare provider. You may need a pregnancy test to make sure you are not pregnant before you start using EluRyng. Use another birth control method such as male condoms with spermicide for the first 7 days in addition to EluRyng. If you are breastfeeding you should not use EluRyng. Use other birth control methods until you are no longer breastfeeding. Step 1. Choose a position for insertion of EluRyng. Choose the position that is comfortable for you. For example, lying down, squatting, or standing with 1 leg up (See Figures A, B, and C) . Positions for EluRyng insertion Figure A Figure B Figure C Step 2. Open the pouch to remove your EluRyng. Each EluRyng comes in a re-sealable foil pouch. Wash and dry your hands before removing EluRyng from the foil pouch. Open the foil pouch at either notch near the top. Keep the foil pouch so you can place your used EluRyng in it before you throw it away in your household trash. Step 3. Prepare EluRyng for insertion. Hold EluRyng between your thumb and index finger and press the sides of the ring together (See Figures D and E) . Figure D Figure E Step 4. Insert EluRyng into your vagina. Insert the folded EluRyng into your vagina and gently push it further up into your vagina using your index finger (See Figures F and G). When you insert EluRyng it may be in different positions in your vagina, but EluRyng does not have to be in an exact position for it to work (See Figures H and I). EluRyng may move around slightly within your vagina. This is normal. Although some women may be aware of EluRyng in the vagina, most women do not feel it when it is in place. Figure F Figure G Figure H Figure I Inserting EluRyng ( Figure F, Figure G) and positioning EluRyng ( Figure H, Figure I) Note: If the EluRyng feels uncomfortable, you may not have pushed the ring into your vagina far enough. Use your finger to gently push the EluRyng as far as you can into your vagina. There is no danger of EluRyng being pushed too far up in the vagina or getting lost (See Figure G) . Some women have accidentally inserted EluRyng into their bladder. If you have pain during or after insertion and you cannot find EluRyng in your vagina, call your healthcare provider right away. Regularly check that EluRyng is in your vagina (for example, before and after intercourse) to ensure you are protected from pregnancy. Step 5. How do I remove EluRyng? Wash and dry your hands. Choose the position that is most comfortable for you (See Figures A, B, and C) . Put your index finger into your vagina and hook it through the EluRyng. Gently pull downward and forward to remove the EluRyng and pull it out (See Figure J) . Figure J Step 6. Throw away the used EluRyng . Place the used EluRyng in the re-sealable foil pouch and put it in a trash can out of the reach of children and pets. Do not throw EluRyng in the toilet. What else should I know about using EluRyng? What if I leave EluRyng in too long? If you leave EluRyng in your vagina for up to 4 weeks (28 days) you will still be getting pregnancy protection. Remove your old EluRyng for 1 week (7 days) and insert a new EluRyng 1 week (7 days) later (See Steps 1 through 4) . If you leave EluRyng in your vagina longer than 4 weeks (28 days), remove the ring and check to make sure you are not pregnant. If you are not pregnant, insert a new EluRyng (See Steps 1 through 4). You must use another birth control method, such as male condoms with spermicide, until the new EluRyng has been used for 7 days in a row. What should I do if my EluRyng comes out of my vagina? EluRyng can slip or accidentally come out (expelled) of your vagina, for example, during sexual intercourse, bowel movements, use of tampons, or if it breaks. EluRyng may break causing the ring to lose its shape. If the ring stays in your vagina this should not lower EluRyng’s effectiveness at preventing pregnancy. If EluRyng breaks and slips out of your vagina, throw the broken ring in your household trash out of the reach of children and pets. Insert a new EluRyng (See Steps 1 through 4) . You should pay attention when removing a tampon to be sure that your EluRyng is not accidentally pulled out. Be sure to insert EluRyng before inserting a tampon. If you accidentally pull out your EluRyng while using tampons, rinse your EluRyng in cool to lukewarm (not hot) water and insert it again right away. EluRyng can be pushed out of (expelled from) your vagina, for example, during sexual intercourse or during a bowel movement. If the expelled ring has been out of your vagina for less than 3 hours, rinse the expelled EluRyng in cool to lukewarm (not hot) water and insert it again right away. If the expelled EluRyng has been out of your vagina for more than 3 continuous hours: During Weeks 1 and 2, you may not be protected from pregnancy. Reinsert the ring as soon as you remember (See Steps 1 through 4) . Use another birth control method, such as male condoms with spermicide, until the ring has been in place for 7 days in a row. During Week 3, do not reinsert the EluRyng that has been out of your vagina; but throw it away in your household trash away from children and pets. Use another birth control method, such as male condoms with spermicide, until the new EluRyng has been used for 7 days in a row, following one of the two options below: - Option 1. Insert a new ring right away to start your next 21 Day EluRyng use cycle. You may not have your regular period, but you may have spotting or vaginal bleeding. - Option 2. Insert a new ring no later than 7 days from the time the previous ring was removed or expelled. During this time, you may have your period. Note: You should only choose to do option 2 if you used EluRyng for 7 days in a row, prior to the day that your previous EluRyng was accidentally removed or expelled. If EluRyng was out of the vagina for an unknown amount of time, you may not be protected from pregnancy. Perform a pregnancy test prior to inserting a new ring and consult your healthcare provider.

14 CLINICAL STUDIES In three large one-year clinical trials enrolling 2,834 women aged 18 to 40 years, in North America, Europe, Brazil, and Chile, the racial distribution was 93% Caucasian, 5.0% Black, 0.8% Asian, and 1.2% Other. Women with BMI ≥ 30 kg/m 2 were excluded from these studies. Based on pooled data from the three trials, 2,356 women aged < 35 years completed 23,515 evaluable cycles of EluRyng use (cycles in which no back-up contraception was used). The pooled pregnancy rate (Pearl Index) was 1.28 (95% CI [0.8, 1.9]) per 100 women-years of EluRyng use. In the US study, the Pearl Index was 2.02 (95% CI [1.1, 3.4]) per 100 women-years of EluRyng use. Study data indicate the return of ovulation and spontaneous menstrual cycles in most women within a month after discontinuation of EluRyng use.

8.5 Geriatric Use EluRyng has not been studied in postmenopausal women and is not indicated in this population.

8.4 Pediatric Use Safety and efficacy of EluRyng have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal adolescents under the age of 18 and for users 18 years and older. Use of this product before menarche is not indicated.

8.1 Pregnancy Risk Summary EluRyng is contraindicated during pregnancy because there is no need for pregnancy prevention in a woman who is already pregnant. Epidemiologic studies and meta-analyses have not shown an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following maternal exposure to low dose CHCs prior to conception or during early pregnancy. No adverse developmental outcomes were observed in pregnant rats and rabbits with the administration of etonogestrel during organogenesis at doses approximately 300 times the anticipated daily vaginal human dose (~0.002 mg/kg/day). No adverse developmental outcomes were observed in pregnant rats and rabbits with the co-administration of the combination desogestrel/ethinyl estradiol during organogenesis at desogestrel/ethinyl estradiol doses at least 2/5 times, respectively, the anticipated daily vaginal human dose (~0.002 desogestrel/0.00025 ethinyl estradiol mg/kg/day). Discontinue EluRyng use if pregnancy is confirmed. Data Animal Data In rats and rabbits at dosages up to 300 times the anticipated dose, etonogestrel is neither embryotoxic nor teratogenic. Co-administration of a maternally toxic dose of desogestrel/ethinyl estradiol to pregnant rats was associated with embryolethality and wavy ribs at a desogestrel/ethinyl estradiol dose that was 40/130 times, respectively, the anticipated vaginal human dose (0.002 desogestrel/0.00025 ethinyl estradiol mg/kg/day). No adverse embryofetal effects were observed when the combination was administered to pregnant rats at a desogestrel/ethinyl estradiol dose that was 4/13 times, respectively, the anticipated vaginal human dose. When desogestrel/ethinyl estradiol was given to pregnant rabbits, pre-implantation loss was observed at a desogestrel/ethinyl estradiol dose that was 3/10 times, respectively, the anticipated vaginal human dose. No adverse embryofetal effects were observed when the combination was administered to pregnant rabbits at a desogestrel/ethinyl estradiol dose that was 2/5 times the anticipated vaginal human dose.

8 USE IN SPECIFIC POPULATIONS Nursing mothers: Not recommended; can decrease milk production.

Harmful effects have not been observed in breastfed infants exposed to CHCs through breast milk. CHCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. When possible, advise the nursing mother to use non-estrogen-containing contraception until she has completely weaned her child. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for EluRyng and any potential adverse effects on the breastfed child from EluRyng or from the underlying maternal condition. 8.4 Pediatric Use Safety and efficacy of EluRyng have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal adolescents under the age of 18 and for users 18 years and older. Use of this product before menarche is not indicated. 8.5 Geriatric Use EluRyng has not been studied in postmenopausal women and is not indicated in this population. 8.6 Hepatic Impairment The effect of hepatic impairment on the pharmacokinetics of EluRyng has not been studied. Steroid hormones may be poorly metabolized in patients with impaired liver function. Acute or chronic disturbances of liver function may necessitate the discontinuation of CHC use until markers of liver function return to normal [see Contraindications (4) and Warnings and Precautions (5.3) ]. 8.7 Renal Impairment The effect of renal impairment on the pharmacokinetics of EluRyng has not been studied.

The date should not exceed either 4 months from the date of dispensing or the expiration date, whichever comes first.

WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS Cigarette smoking increases the risk of serious cardiovascular events from combination hormonal contraceptive (CHC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, CHCs, including EluRyng, should not be used by women who are over 35 years of age and smoke [see Contraindications (4) ]. WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS See full prescribing information for complete boxed warning. Women over 35 years old who smoke should not use EluRyng. (4) Cigarette smoking increases the risk of serious cardiovascular events from combination hormonal contraceptive (CHC) use. (4)
