Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Benzydamine use is not advisable in patient with hypersensitivity to salicylic acid or other NSAIDs.

Bronchospasm may be precipitated in patients suffering from or with a previous history of bronchial asthma. Caution should be exercised in these patients.

In a minority of patients, buccal/pharyngeal ulceration may be caused by serious disease processes. Patients whose symptoms worsen or do not improve within 3 days, or who appear feverish or have other symptoms, must therefore seek the advice of their doctor or dentist as appropriate.

Difflam contains:

- Isomalt: patients with rare hereditary problems of fructose intolerance should not take this medicine.

- Sunset yellow (E 110): may cause allergic reactions.

No interaction studies have been performed.

Pregnancy

There are no or limited amount of data from the use of benzydamine in pregnant women, and animal studies are insufficient with respect to reproductive toxicity (see section 5.3).

Difflam should not be used during pregnancy.

Breast-feeding

There is insufficient information on the excretion of benzydamine in human milk.

Difflam should not be used during breast-feeding.

Difflam has no or negligible influence on the ability to drive and use machine, when it is used at the recommended dose.

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness

The following rate values have been used: Very common (≥ 1/10), Common (≥ 1/100 to <1/10), Uncommon (≥1/1,000 to <1/100), Rare (≥1/10,000 to <1/1,000) and Very rare (<1/10,000), not known (cannot be estimated from the available data).

Reporting of suspected adverse reactions.

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA yellow car in the Google Play or Apple App Store.

Symptoms

No overdosage with the lozenge formulation has been reported. However, very rarely in children excitation, convulsions, sweating, ataxia, tremor and vomiting have been reported after the oral administration of benzydamine dosages about 100 times higher than those of the lozenge.

Management

In the event of acute overdosage only symptomatic treatment is possible; the stomach should be emptied by inducing vomiting or by gastric lavage, and the patient carefully observed and given supportive treatment. Adequate hydration must be maintained.

Pharmacotherapeutic group: other throat preparations, ATC code: R02AX03.

Clinical efficacy and safety

Clinical studies demonstrate that benzydamine is effective in relieving suffering from localised irritation processes of the mouth and pharynx. In addition, benzydamine possesses a moderate local anaesthetic effect.

Absorption

The absorption through the mucosa of the mouth and pharynx was demonstrated by the presence of measurable quantities of benzydamine in the human plasma.

Distribution

About 2 hours after the 3 mg lozenge administration, benzydamine peak plasma values of 37.8 ng/ml with an AUC of 367 ng/ml*h were observed. However, these levels are not sufficient to produce pharmacological systemic effects.

When locally applied benzydamine has been shown to accumulate in inflamed tissues where it reaches effective concentrations because of its capacity to penetrate the epithelial lining.

Biotransformation and elimination

The excretion occurs mainly in the urine and mostly in the form of inactive metabolites or conjugation products.

Development and peri-post natal toxicity was seen in reproductive toxicity studies in rats and rabbits at plasma concentration much higher (up to 40 times) than those observed after a single therapeutic oral dose. No teratogenic effects were seen in those studies. Available kinetic data do not allow to establish the clinical relevance of the reproductive toxicity studies. As the preclinical studies had shortcomings and therefore are of restricted value, they do not provide additional information relevant for the prescriber beyond that included in other sections of the SPC.
