Difflam Oral Rinse

A pleasant tasting, clear, green solution, containing benzydamine hydrochloride 0.15% w/v.

Liquid for use as mouthwash/gargle.

Difflam Oral Rinse is a locally acting analgesic and anti-inflammatory treatment for the relief of painful inflammatory conditions of the mouth and throat including:

Traumatic conditions: Pharyngitis following tonsillectomy or the use of a naso-gastric tube.

Inflammatory conditions: Pharyngitis, aphthous ulcers and oral ulceration due to radiation therapy.

Dentistry: For use after dental operations.

Adults: Rinse or gargle with 15 ml (approximately 1 tablespoonful) every 1½ to 3 hours as required for pain relief.

The solution should be expelled from the mouth after use.

Children: Not suitable for children aged 12 years or under.

Elderly: No special dosage recommendations are made for elderly patients.

Difflam Oral Rinse should generally be used undiluted, but if 'stinging' occurs the rinse may be diluted with water.

Uninterrupted treatment should not exceed seven days, except under medical supervision

Difflam Oral Rinse is contra-indicated in patients with known hypersensitivity to any of the ingredients

Difflam Oral Rinse should generally be used undiluted, but if 'stinging' occurs the rinse may be diluted with water.

Avoid contact with eyes.

Difflam should not be used in pregnancy or lactation unless considered essential by the physician. There is no evidence of a teratogenic effect in animal studies.

Not applicable.

Side-effects are minor. Occasionally, oral tissue numbness or 'stinging' sensations may occur. Hypersensitivity reactions occur very rarely but may be associated with pruritus rash, urticaria, photodermatitis and occasionally laryngospasm or bronchospasm.

Difflam is unlikely to cause adverse systemic effects, even if accidental ingestion should occur. No special measures are required.

Benzydamine exerts an anti-inflammatory and analgesic effect by stabilising the cellular membrane and inhibiting prostaglandin synthesis.

Oral doses of benzydamine are well absorbed and plasma drug concentrations reach a peak fairly rapidly and then decline with a half-life of about 13 hours. Less than 20% of the drug is bound to plasma proteins.

Although local drug concentrations are relatively large, the systemic absorption of mouthwash-gargle doses of benzydamine is relatively low compared to oral doses. This low absorption should greatly diminish the potential for any systemic drug side-effects when benzydamine is administered by this route. Benzydamine is metabolized primarily by oxidation, conjugation and dealkylation.

Non-Clinical Data reveal no special hazards for humans based on conventional studies of safety pharmacology, repeated toxicity, genotoxicity, cardiogenic potential, and toxicity to reproduction.
