Acne vulgaris, acneform eruptions, folliculitis.
Route of administration
For topical use only.
Adults, children and the elderly
By gentle massage over all the affected area two or three times daily.
Acne rosacea. Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
Avoid contact with eyes, mouth and mucous membranes. Caution is required when applying to the neck and other sensitive areas. May bleach hair or dyed fabrics.
As Quinoderm Cream may cause increased sensitivity to sunlight, sunlamps should not be used and deliberate or prolonged exposure to sunlight should be avoided or minimised. When exposure to strong sunlight cannot be avoided, patients should be advised to use a sunscreen product and wear protective clothing.
In a few isolated cases, overreaction to Quinoderm Cream may occur. To minimise this possibility, select a small area of skin behind the ear, apply the cream and leave for 12 hours. If severe irritation or pronounced redness occurs, do not proceed with treatment.
The product should only be used with caution in areas of thin or sensitive skin. Fair skinned individuals are likely to be particularly sensitive to irritation. Quinoderm Cream should not be used in patients with fair or sensitive skin if there is extensive exposure to sunlight or ultraviolet light.
Where local irritation or inflammation may result, use should be interrupted or frequency reduced. If itch or rash occur treatment should cease and a doctor or pharmacist consulted (See section 4.8 Undesirable effects).
Patients should be advised that excessive application will not improve efficacy, but may increase the risk of skin irritation.
Instruct patients not to smoke or go near naked flames – risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce build-up but not totally remove it.
Benzoyl Peroxide is an oxidising agent. Hence, Quinoderm Cream should not be used at the same time as other topical agents which would react with an oxidising agent.
Zinc oxide inhibits the antibacterial and antimycotic effects of hydroxyquinoline. Concurrent use of zinc oxide is not recommended.
Concurrent administration with oral isotretinoin should be avoided.
If combination topical treatment is required with tretinoin, isotretinoin, or tazarotene, the products should be applied at different times of the day (e.g., one in the morning and the other in the evening) to minimise irritation and maximise efficacy.
Quinoderm Cream is not contra-indicated in pregnancy.
Topical benzoyl peroxide has not been studied during breastfeeding. Because only about 5% benzoyl peroxide is absorbed following topical application, it is considered a low risk to the nursing infant. Ensure that the infant's skin does not come into direct contact with the areas of skin that have been treated.
No data on human fertility is available.

Pharmacotherapeutic Group: Benzoyl Peroxide, combinations
ATC Code: D10AE51
The combination of the mild keratolytic properties of benzoyl peroxide and the antibacterial and antifungal properties of potassium hydroxyquinoline sulfate in a specially formulated bland water-miscible base make this preparation valuable in the treatment of acne vulgaris, acneform eruptions and folliculitis.
Approximately 5% of benzoyl peroxide is absorbed following topical application.
Any absorbed drug appears to be metabolised in the skin to benzoic acid and rapidly excreted in the urine.
