Duac contains the antibiotic clindamycin and also benzoyl peroxide. Do not use it if you are allergic to any of the ingredients.
You should apply topical treatments to all the affected areas of skin and not just to each spot. Duac is to be used once a day in the evening to the entire affected area. First, wash the area using a mild cleanser and dry it thoroughly. Then apply the gel in a thin layer. Wash your hands after use.
Avoid contact with the mouth, eyes, lips, other mucous membranes or areas of irritated or broken skin. Rinse well with water if any accidental contact occurs.
Many people notice increased reddening and peeling of the skin in the first few weeks. If that is the case, then you can use a moisturiser, or reduce the frequency of use, or temporarily discontinue use until the skin settles.
If the skin irritation is severe, then stop using the gel.
Topical antibiotics help to reduce the number of bacteria on the skin and treat the inflamed spots.
It will usually take four to six weeks before you see any improvement in your skin. Duac should not be used for more than 12 weeks continuously. Often people think the treatment is not working after a few weeks and stop using it. However, it is important to continue to ensure you see a result, as it will usually take time for your skin to respond.
Many people will find that acne flares up again once the antibiotic treatment has stopped. Maintenance treatment will usually be required, and often this can be for up to 4-5 years. Maintenance treatment tends to be with either benzoyl peroxide or a topical retinoid ( such as adapalene, tretinoin, isotretinoin) which can be used indefinitely.
Long-term antibiotics for maintenance are not recommended as it can lead to resistance of bacteria to the antibiotics.
Duac generally has a shelf life of 8 weeks once opened, but please check the packaging. Never give your medication to other people even if their condition appears to be the same as yours.
