How to use
- What it is and how it works
Clindamycin is a topical antibiotic and benzoyl peroxide reduces acne-associated bacteria while helping limit antibiotic resistance. The 1% + 3% and 1% + 5% gels are for mild to moderate inflammatory acne.
- Apply it as prescribed
Apply a thin layer once daily in the evening over the whole affected area, not only individual spots. Use it on clean, dry, intact skin and avoid the eyes, mouth and mucosa. Wash your hands afterwards.
- Skin care and interactions
Do not combine it with recent clindamycin or erythromycin, another benzoyl peroxide product or a topical retinoid unless reviewed by the prescriber. Avoid abrasive or drying cosmetics. Let the gel dry before fabric contact because it can bleach colours.
First 5 weeks. Photograph your face in the same light at the start and at 4 weeks. Redness, peeling and dryness are expected; use a moisturiser after the gel and SPF in the morning. Stop immediately and contact your doctor if you develop severe or prolonged diarrhoea; antibiotic-associated colitis has been reported with topical clindamycin.
Weeks 5-12. Do not use tretinoin, isotretinoin, tazarotene or erythromycin products at the same time unless your doctor has reviewed the combination. Keep the gel away from coloured fabric and hair; benzoyl peroxide bleaches. At 12 weeks the antibiotic stops. Compare photos with your doctor to choose an antibiotic-free maintenance plan.

How it compares

Side effects
Local irritation
Mild redness, dryness, stinging or peeling can occur, especially at the start. Use a gentle moisturiser and follow the prescribed adjustment plan. Stop and seek advice if the reaction is marked or persistent.
Diarrhoea and bowel inflammation
Topical clindamycin can rarely be associated with colitis. Stop the gel and seek prompt medical assessment for severe, persistent or bloody diarrhoea, abdominal cramps or fever.
Do not use if
- You are allergic to clindamycin, lincomycin, benzoyl peroxide or another ingredient
- You have Crohn's disease, ulcerative colitis or a history of antibiotic-associated colitis
- You are pregnant or breastfeeding, or recently used clindamycin or erythromycin, without a clinical review
When to contact your doctor
- Facial swelling, breathing difficulty, widespread blistering, eye pain, light sensitivity or altered vision: seek urgent medical care
- Severe, prolonged or bloody diarrhoea: stop the gel and seek medical care immediately
- Acne is worsening or scarring, or there is no satisfactory response by the planned review
Storage
Keep the tube tightly closed in its original package, out of children's reach. Follow the temperature and expiry instructions on the label and do not use the product after it expires.
What to expect
An early response may appear within 2–5 weeks. Complete only the prescribed course and review by 12 weeks; antibiotic-containing gel is not a long-term maintenance treatment.
