Who qualifies
Duac is a prescription-only combination gel indicated for mild-to-moderate inflammatory acne. A licensed doctor must evaluate your skin photos to ensure topical antimicrobial therapy is suitable for your specific lesion type.
| Condition / Presentation | Eligibility Status | Clinical Pathway |
|---|---|---|
| Mild-to-moderate inflammatory acne (papules, pustules) | Eligible | Topical Duac gel (capped at 12 weeks) |
| Comedonal acne without inflammation | Alternative recommended | Topical retinoids or azelaic acid 15% gel |
| Severe nodulocystic or scarring acne | Ineligible online | Referred to in-person specialist care |
| Pregnancy or active breastfeeding | Ineligible for Duac | Safer alternatives (e.g., azelaic acid 15% gel) assessed |
Hi-Doctor exclusively prescribes topical dermatological treatments. Severe, nodulocystic, or deeply scarring acne requires direct physical examination and is referred to in-person care. Oral isotretinoin and oral antibiotics are strictly out of scope for our online service.
What Duac actually does
Duac combines two synergistic active ingredients: clindamycin 1% (a lincosamide antibiotic) and benzoyl peroxide (3% or 5%). Clindamycin inhibits the protein synthesis of Cutibacterium acnes, rapidly suppressing bacterial proliferation inside clogged pores.
Benzoyl peroxide provides potent oxidising antimicrobial action alongside mild keratolytic and comedolytic effects. Crucially, the benzoyl peroxide component prevents C. acnes from developing resistance to clindamycin, which is why clindamycin is never prescribed as a monotherapy.
You apply Duac once nightly to clean, dry skin. Visible changes take time: retinoid or antimicrobial purging and minor dryness can occur in weeks 2 to 6, with meaningful clinical improvement evaluated at 12 weeks, not before. Because prolonged topical antibiotic use increases resistance risks, a Duac treatment course is capped at 12 weeks.
Side effects and when to stop
Most patients experience mild local cutaneous reactions during the initial weeks of application.
- Common reactions: Mild erythema, skin peeling, dryness, burning, and localized stinging.
- Fabric bleaching: Benzoyl peroxide bleaches coloured towels, clothing, and bed linen on contact.
- When to discontinue: Stop treatment and consult a doctor immediately if you develop severe contact dermatitis, intense facial swelling, or persistent abdominal cramping and watery diarrhoea (symptoms of antibiotic-associated colitis).
