Drug Description

Presentation

Indications

Adult Dosage

Differin Cream should be applied to the acne affected areas once a day before retiring and after washing. A thin film of cream should be applied, with the fingertips, avoiding the eyes and lip. Ensure that the affected areas are dry before application.

Since it is customary to alternate therapies in the treatment of acne, it is recommended that the physician assess the continued improvement of the patient after three months of treatment with Differin Cream.

With patients for whom it is necessary to reduce the frequency of application or to temporarily discontinue treatment, frequency of application may be restored or therapy resumed once it is judged that the patient can again tolerate the treatment.

If patients use cosmetics, these should be non-comedogenic and non-astringent.

The safety and effectiveness of Differin Cream have not been studied in neonates and young children.

Child Dosage

Contra Indications

Hypersensitivity to any ingredient of the product.

Special Precautions

If a reaction suggesting sensitivity or severe irritation occurs, use of the medication should be discontinued. If the degree of local irritation warrants, patients should be directed to use the medication less frequently, to discontinue use temporarily, or to discontinue use altogether. Differin Cream should not come into contact with the eyes, mouth, angles of the nose or mucous membranes.

If product enters the eye, wash immediately with warm water. The product should not be applied to either broken (cuts and abrasions), sunburnt or eczematous skin, nor should it be used in patients with severe acne, or acne involving large areas of the body, especially in women of child bearing age who are not on effective contraception.

Exposure to sunlight and artificial UV irradiation, including sunlamps, should be minimised during use of adapalene. Patients who normally experience high levels of sun exposure and those with inherent sensitivity to sun, should be warned to exercise caution. Use of sunscreen products and protective clothing over treated areas is recommended when exposure cannot be avoided.

Methyl parahydroxybenzoate (E218) and propyl parahydroxybenzoate (E216) may cause allergic reactions which can possibly be delayed.

Interactions

There are no known interactions with other medications which might be used cutaneously and concurrently with Differin Cream; however, other retinoids or drugs with a similar mode of action should not be used concurrently with adapalene.

Adapalene is essentially stable to oxygen and light and is chemically non-reactive. Whilst extensive studies in animals and man have shown neither phototoxic nor photoallergic potential for adapalene, the safety of using adapalene during repeated exposure to sunlight or UV irradiation has not been established in either animals or man. Exposure to excessive sunlight or UV irradiation should be avoided.

Absorption of adapalene through human skin is low and therefore interaction with systemic medications is unlikely. There is no evidence that the efficacy of oral drugs such as contraceptives and antibiotics is influenced by the cutaneous use of Differin Cream.

Differin Cream has a potential for mild local irritation, and therefore it is possible that concomitant use of peeling agents, astringents or irritant products may produce additive irritant effects. However, cutaneous antiacne treatment e.g. erythromycin (up to 4%) or clindamycin phosphate (1% as the base) solutions or benzoyl peroxide water based gels up to 10% may be used in the morning when Differin Cream is used at night as there is no mutual degradation or cumulative irritation.

Adverse Reactions

Side effects include skin irritation (erythema, dryness, scaling, burning) and stinging at the site of application which is reversible when treatment is reduced in frequency or discontinued. Eyelid oedema as well as eye irritation when the product comes into contact with the eyes have been reported rarely.
