Clindamycin (Topical) — NZ Medication Guide
📋 Reviewed by a Registered Pharmacist NZ — This information is for general educational purposes only and does not replace professional medical advice. Always consult your doctor or pharmacist before starting, stopping, or changing any medication.
What is Clindamycin (Topical)?
Topical clindamycin is a lincosamide antibiotic used for acne vulgaris — typically in combination with benzoyl peroxide. This medication is funded by Pharmac for acne.
What is Clindamycin (Topical) Used For?
Topical clindamycin 1% is used for mild to moderate acne vulgaris, particularly papulopustular acne. It should always be combined with benzoyl peroxide (or other non-antibiotic agents) to prevent C. acnes antibiotic resistance.
How Does Clindamycin (Topical) Work?
Clindamycin inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit in C. acnes, reducing bacterial colonisation of follicles and decreasing local inflammatory mediator release.
How to Take Clindamycin (Topical)
Apply a thin layer to the affected area once or twice daily after cleansing. Use in combination with benzoyl peroxide (either as a combination product such as Duac® or as separate products applied at different times). Do not use topical clindamycin alone — use with benzoyl peroxide to prevent resistance.
Common Side Effects of Clindamycin (Topical)
- Skin dryness
- Mild stinging on application
- Oiliness (with gel formulation)
Serious Side Effects — Seek Medical Attention
Contact your doctor or call 111 immediately if you experience any of the following:
- Clostridioides difficile colitis (rare with topical application — but reported; report persistent diarrhoea)
- Antibiotic resistance (significant concern — always combine with benzoyl peroxide or retinoid)
Drug Interactions
Clindamycin (Topical) may interact with other medicines. Always inform your doctor and pharmacist of all medications you are taking. Key interactions include:
- Erythromycin (antagonism — avoid combining topical clindamycin and erythromycin)
New Zealand Prescribing Information
Clindamycin 1% topical gel (Clindatech® and generics) is funded by Pharmac. The combination product clindamycin/benzoyl peroxide (Duac®) is also available. NZ dermatology guidelines emphasise avoiding antibiotic monotherapy for acne — always combine topical antibiotics with benzoyl peroxide to prevent resistance. Duration of topical antibiotic use should be limited to 3 months, then review.
Frequently Asked Questions
Why should topical clindamycin always be combined with benzoyl peroxide?
Using topical antibiotics alone for acne selects for antibiotic-resistant C. acnes bacteria over time, making treatment less effective for you and contributing to broader resistance. Benzoyl peroxide kills bacteria via a non-antibiotic mechanism and prevents resistance development. Always use them together.
Can topical clindamycin cause C. difficile?
Oral clindamycin carries a well-known C. difficile risk. Topical application results in very low systemic absorption, making C. difficile colitis very rare but not impossible with topical clindamycin. Report any persistent, severe, or bloody diarrhoea during treatment to your doctor.
