What is IsotrexIN Gel?  

IsotrexIN Gel is a prescription acne treatment containing a combination of Isotretinoin and Erythromycin. IsotrexIN Gel works by reducing oil production in the skin and killing the bacteria that cause spots. IsotrexIN Gel is used to treat acne in young people who are going through or have gone through puberty. IsotrexIN helps to loosen blackheads and whiteheads so it is easier to extract them. IsotrexIN Gel stops the formation of new blackheads and whiteheads from forming, and IsotrexIN Gel also reduces the number of red, swollen acne spots. 

How do you take IsotrexIN Gel?  

  1. Wash your hands.
    2. Completely remove any make-up.
    3. Wash the area with a mild soap and warm water, and dry gently.
    4. Put a thin layer of Gel on the affected skin, using your fingertips, and smooth in.
    5. Apply to all of the area of your skin which has acne, not just each spot.
    6. Wash your hands after using the IsontrexIN Gel. 

If you use too much IsontrexIN Gel, or use it more frequently than you should, it may cause redness, peeling or
irritation of your skin. If this happens, use IsorexIN Gel less often or stop using it for a few days and then start again. Using more Gel than you should will not help your spots clear up more quickly. 

If you accidentally swallow IsontrexIN Gel.
The ingredients of IsontrexIN Gel should not be harmful if swallowed in small amounts.
• If you accidentally get IsontrexIN Gel in your mouth, rinse at once with plenty of water
• Talk to a doctor if you swallow a lot of IsontrexIN Gel.
