1. What Isotrexin is and what it is used for
The name of this medicine is Isotrexin Gel (called Isotrexin in this leaflet),
which is used to treat moderate acne. Isotrexin contains two different medicines called erythromycin and isotretinoin.
 Erythromycin is an antibiotic. It works by fighting bacteria that can
cause acne (spots).
 Isotretinoin is similar to vitamin A. It works by helping the skin so that
blocked pores are less likely.
This helps prevent spots.
Isotrexin helps to:
make your skin less oily
loosen blackheads and whiteheads so that they come out more
stop new blackheads, whiteheads and spots from forming
lower the number of bacteria which can cause acne
lower the number of red, inflamed acne spots.

ingredients of Isotrexin (listed in Section 6).

blood vessels and tiny pimples usually on the central area of the face)
and perioral dermatitis (red and sometimes bumpy rash around the
mouth and chin area).
Do not use Isotrexin if the above applies to you. If you are not sure, ask
your doctor or pharmacist before using this medicine.
Taking other medicines
Please tell your doctor or pharmacist if you are using or have recently used
any other medicines. This includes medicines obtained without a prescription, including herbal medicines.
In particular, tell your doctor or pharmacist before using your medicine if:
 you are using any other acne treatment such as:
- a product containing a topical antibiotic
- medicated or abrasive soaps or cleansers
- products which have a drying effect on the skin, such as cosmetics
or other products which contain alcohol or which otherwise make
the skin feel tight (known as astringents) and especially
- products containing peeling agents such as benzoyl peroxide.
Following prolonged use of a peeling agent, it is advisable to “rest”
the skin until the peeling effects subside before starting to use
These products should be used with caution to avoid a cummulative irritant
effect occurring.
If you are not sure if the above applies to you, check with your doctor or
pharmacist before using Isotrexin.
