What is Duac Once Daily 10mg/g + 50mg/g Gel?

The gel is described as suitable for people aged 12 years and older with mild to moderate acne. It is applied to the skin rather than taken by mouth.
What is Duac used for?

- mild to moderate acne in adolescents and adults
- comedonal, papular, and pustular acne
- situations where a dual-action topical approach is needed
If you are unsure whether your acne type matches this description, a doctor or pharmacist can help you check the official leaflet and treatment options.

Who should not use Duac?
The original content lists the following contraindication-related points:
- known hypersensitivity to clindamycin, benzoyl peroxide, or any component of the gel

It also notes that people using other topical acne treatments should be cautious because of the risk of added irritation. If you are unsure about suitability, check with a healthcare professional before use.
Precautions and warnings
Several precautions were highlighted in the source content:
- avoid contact with the eyes, mouth, and mucous membranes
- use sunscreen during the day, as benzoyl peroxide may increase sun sensitivity

It is also sensible to tell a healthcare professional about any other medicines or skin products you are using, especially if they may irritate the skin.
Possible side effects
The original content lists the following possible side effects:
- skin irritation
- redness and peeling
- dryness or itching
- increased sensitivity to sunlight
Side effects are not the same for everyone. If symptoms are persistent, severe, or worrying, seek advice from a healthcare professional.
What to do if too much is applied

If a large area is affected or the reaction seems significant, contact a healthcare professional for guidance.
