For full list of excipients see 6.1.
Clear very pale yellow gel.
The treatment of acute inflammatory exacerbations of rosacea.
For cutaneous use only.
(i) For adults and the elderly. Apply the gel to the affected area of the skin in a thin film twice daily for 8 weeks. Thereafter further applications may be necessary depending on the severity of the condition.
(ii) For Children. Not recommended.
Known hypersensitivity to metronidazole, parabens or any of the constituents.
Warnings: Avoid contact with the eyes. If contact with the eyes occurs the gel should be washed out carefully with water.
Precautions: The following statements take into account the possibility that metronidazole may be absorbed after topical application. However there is no evidence of any significant systemic concentrations of metronidazole following topical applications. Peripheral neuropathy has been reported in association with prolonged use of oral metronidazole. The elimination half-life of metronidazole remains unchanged in the presence of renal failure. Such patients, however, retain the metabolite of metronidazole. The clinical significance of this is not known at present. However in patients undergoing haemodialysis, metronidazole and its metabolites are efficiently removed.
Contains methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) and ethyl parahydroxybenzoate (E214), may cause allergic reactions (possibly delayed).
Patients are advised not to take alcohol during systemic metronidazole therapy because of the possibility of a disulfiram-like reaction.
Some potentiation of anti-coagulant therapy has been reported when metronidazole has been used with the warfarin type oral anticoagulants.
Patients receiving phenobarbitone metabolise metronidazole at a much faster rate than normal, reducing the half-life to 3 hours.
The safety of topically applied metronidazole in pregnancy and lactation has not been adequately established and should not be used in these circumstances unless the physician considers it essential.
No adverse effects on the ability to drive or use machines has been reported following the topical application of metronidazole.
Dryness or irritation of the skin may be experienced after application to unbroken skin. Systemic metronidazole therapy may occasionally cause an unpleasant taste in the mouth, furred tongue, nausea, vomiting, gastro-intestinal disturbance, urticaria, angioedema and anyphylaxis. Drowsiness, dizziness, headache, ataxia, skin rash, pruritis and darkening of urine has been reported, but rarely.
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: Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Overdose is unlikely. If necessary remove the medication by washing with warm water. If accidental ingestion occurs, an appropriate method of gastric emptying may be used if considered appropriate.
ATC Code: D06BX01
Metronidazole is a 5-nitroimidazole derivative with activity against anaerobic protozoa and anaerobic bacteria. It also has a radiosensitising effect of hypoxic tumour cells. Its mechanism of action is thought to involve interference with DNA by a metabolite in which the nitro group of metronidazole has been reduced. The mode of action of topical metronidazole in the treatment of rosacea is not known.
No bioavailability studies have been carried out with this formulation.
There are no preclinical data of relevance to the prescriber, which have additional to those already included in other sections of the SmPC.
