What is Isotrex Gel used for?

Stopping new blackheads, whiteheads and spots from forming
Lowering the number of red, inflamed acne spots.
Your doctor may have prescribed Isotrex Gel for another reason.

How do I use Isotrex Gel?

How much to use

Use Isotrex Gel as directed by your doctor or pharmacist.
Use Isotrex Gel once daily at night time over the whole of the affected area. Your doctor will tell you how many times to use the medicine.
You should keep using the medicine until your doctor tells you otherwise.

How to apply it

Due to the flammable nature of Isotrex Gel, you should avoid smoking or being near an open flame while you're applying Isotrex Gel, and immediately after you've used it.
Wash your hands.
Completely remove any make-up.
Wash the affected area with a mild soap and warm water, and gently dry.
Put a thin film of gel on the affected skin using your fingertips, and smooth in.
Apply to all the area of your skin which has acne, not just each spot.
Take care not to apply too much gel especially where it could run into your eyes, the angles of your nose, any skin folds, or other areas of the skin that do not require treatment. Applying too much gel or applying it more frequently will not help your spots clear up more quickly, and may cause redness, peeling and discomfort. If this does happen, use the gel less often, or stop using it for a few days and then start again once the irritation subsides.
Wash your hands after using the gel.

How long to use it for

It can take 6 to 8 weeks before you can see the full benefit of Isotrex Gel.
Do not stop using Isotrex Gel or change the dose without first checking with your doctor.

It is not for use by children.

If you forget to use Isotrex Gel

Don't apply a double dose to make up for forgotten doses.
Apply the next dose at the usual time.

What do I do if I take too much? (Overdose)

Immediately telephone your doctor if you think you or anyone else may have used too much Isotrex Gel, even if there are no signs of discomfort or poisoning.
The ingredients of Isotrex Gel are not expected to be harmful if swallowed in the small amounts applied to the face. If you do accidentally get Isotrex Gel in your mouth, rinse at once with plenty of water. Seek medical advice if you swallow a large amount.
If you are not sure what to do, contact your doctor or pharmacist.
