Special Precautions
Contact with the mouth, eyes, lips, other mucous membranes or areas of irritated or broken skin should be avoided. Application to sensitive areas of skin should be made with caution. In case of accidental contact, rinse well with water.
Duac Once Daily Gel should be used with caution in patients with a history of regional enteritis or ulcerative colitis, or a history of antibiotic-associated colitis.
Duac Once Daily Gel should be used with caution in atopic patients, in whom further skin drying may occur.
During the first weeks of treatment, an increase in peeling and reddening will occur in most patients. Depending upon the severity of these side effects, patients can use a non-comedogenic moisturiser, temporarily reduce the frequency of application of Duac Once Daily Gel or temporarily discontinue use; however, efficacy has not been established for less than once daily dosing frequencies.
Concomitant topical acne therapy should be used with caution because a possible cumulative irritancy may occur, which sometimes may be severe, especially with the use of peeling, desquamating, or abrasive agents.
If severe local irritancy (e.g. severe erythema, severe dryness and itching, severe stinging/burning) occurs, Duac Once Daily Gel should be discontinued.
As benzoyl peroxide may cause increased sensitivity to sunlight, sunlamps should not be used and deliberate or prolonged exposure to sun 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.
If a patient has sunburn, this should be resolved before using Duac Once Daily Gel.
If prolonged or significant diarrhoea occurs or the patient suffers from abdominal cramps, treatment with Duac Once Daily Gel should be discontinued immediately, as the symptoms may indicate antibiotic-associated colitis. Suitable diagnostic methods, such as determination of Clostridium difficile and toxin and, if necessary, colonoscopy should be employed and treatment options for colitis considered.
The product may bleach hair or coloured fabrics. Avoid contact with hair, fabrics, furniture or carpeting.
Resistance to clindamycin: Patients with a recent history of systemic or topical clindamycin or erythromycin use are more likely to have pre-existing anti-microbial resistant Propionibacterium acnes and commensal flora (see Pharmacology: Pharmacodynamics under Actions).
Cross-resistance: Cross-resistance may occur with other antibiotics such as lincomycin and erythromycin when using antibiotic monotherapy (see Interactions).
Effects on ability to drive and use machines: Not relevant.
