What is Duac Once Daily Gel and what is it used for?

Duac Once Daily Gel contains clindamycin and benzoyl peroxide.
Clindamycin is an antibiotic, which prevents the growth of bacteria which are involved in acne. Benzoyl peroxide acts to reduce comedones (blackheads and whiteheads). It is also effective at killing the bacteria, which are involved in acne, and makes the skin less oily.
Duac Once Daily Gel is used on the skin to treat acne. It helps to:
reduce the bacteria or germs, which are implicated in acne;
reduce the number of acne spots;
reduce the likelihood of new blackheads and whiteheads from forming; and
make your skin less oily.
Your doctor may have prescribed Duac Once Daily Gel for another purpose. Ask your doctor if you have any questions about why Duac Once Daily Gel has been prescribed for you.
Duac Once Daily Gel is for use by adults and adolescents (aged 12 and above) with acne.
Duac Once Daily Gel is not addictive.
Duac Once Daily Gel is only available with a doctor's prescription.

How to use Duac Once Daily Gel

It is important to use Duac Once Daily Gel exactly as your doctor has told you.
Directions given to you by your doctor may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, tube or this leaflet, ask your doctor or pharmacist for help.

Remove make-up thoroughly before applying the gel. After it has dried, you can use a non-greasy make-up.

How to apply Duac Once Daily Gel

Duac Once Daily Gel is for application to the skin only.
A thin film of gel should be applied to all of the area of the skin which has acne, not just the individual spots. As a guide, one fingertip (the amount of gel squeezed from the tube which reaches from the tip of your finger to the first joint) is enough to cover the face, two and one-half fingertips of gel will cover your face and back. If the gel does not rub into your skin easily, you are using too much.
Wash your hands after applying the gel.
The usual dose for Duac Once Daily Gel is apply once daily in the evening.

How long should you use it for

It may take 4-6 weeks before you see the full effects of Duac Once Daily Gel on your acne.
Use Duac Once Daily Gel for as long as your doctor tells you to.
Do not use Duac Once Daily Gel for more than 11 weeks unless your doctor tells you to.
If you use Duac Once Daily Gel less often than you should, it may not work as well and your skin problem may not improve. Using it more often than you should may not improve your skin problem any faster and may cause or increase side effects.
If you are not sure of how long you need to use Duac Once Daily Gel, talk to your doctor.

If you forget to use it

If it is almost time for your next application of Duac Once Daily Gel, skip the application you missed and apply the gel when you are next meant to. Otherwise, use it as soon as you remember, and then go back to using your gel as you would normally.
Do not apply a double dose to make up for the dose that you missed.
If you have trouble remembering to use your medicine, ask your pharmacist for some hints.

If you swallow it

Immediately telephone your doctor or Poisons Information Centre (In Australia 13 11 26; In New Zealand 0800 POISON or 0800 764 766), or go to casualty at your nearest hospital if you think that you or anyone else may have swallowed Duac Once Daily Gel.
