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.

Treatment should include gastric lavage. In the event of convulsions sedate with intramuscular paraldehyde. Respiratory depression may necessitate mechanical ventilation. Symptomatic treatment of cardiovascular dysfunction should be given with careful patient monitoring. The physician should be aware that tablets in the intestine will continue to release the active ingredients for a period of hours.

Chlorphenamine is a potent H₁-blocking drug. It antagonises the pharmacological actions of histamine released by antigen-antibody reaction in allergic diseases, thus providing symptomatic relief. Chlorphenamine alone is less effective when pollen counts are high, allergen exposure is prolonged and nasal congestion has become prominent.Ephedrine has mild CNS stimulant properties which counteract any drowsiness produced by chlorphenamine. In addition it produces a decongestant action on nasal mucosal surfaces relieving mucosal congestion in conditions such as hay fever and allergic rhinitis.

Chlorphenamine is readily absorbed after oral administration and may undergo enterohepatic re-circulation in man. It is eliminated with a t½ of 12-15 hours. Ephedrine is completely absorbed following oral administration and is eliminated with a t½ of 3-6 hours.

There are no preclinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
