1) What Isotrex Gel is and what it is used for
The name of your medicine is Isotrex Gel. Isotrex Gel contains an
active ingredient called isotretinoin.
 Isotretinoin is similar to Vitamin A. It works by helping the skin so that
blocked pores are less likely.
This helps prevent spots.
Isotrex Gel is used to treat acne (spots) in young people who are going
through or have gone through puberty, and in adults. It is not for use by
children who have not started puberty. Isotrex helps to:
 loosen blackheads and whiteheads so that they come out more easily
 stop new blackheads, whiteheads and spots from forming
 lower the number of red, swollen acne spots.

2) Before you use Isotrex Gel
Do not use Isotrex Gel:
 if you are allergic (hypersensitive) to isotretinoin or any of the other
ingredients in Isotrex (listed in Section 6)
➔ Tell your doctor if any of these apply to you. Don’t use Isotrex Gel.
Take special care with Isotrex Gel
Before you use Isotrex Gel, your doctor needs to know:
 if you or any of your close family have had skin cancer
 if you have had problems tolerating this or similar medicines in the past
(you have found them too irritating for your skin)
 if you have:
 eczema,
 redness of the skin, broken blood vessels and tiny pimples usually in
the centre of the face (rosacea)
 redness and soreness around your mouth (perioral dermatitis).
Isotrex may further irritate these conditions.
 if you have skin reactions in the sunlight
➔ Check with your doctor if you think any of these may apply to you.

Take care not to use too much gel especially where it could run into your
eyes or build up in the angles of your nose, skin folds, or other areas of the
skin that do not require treatment.
Only use Isotrex Gel on your skin. Keep it away from areas such as your
mouth, lips, and eyes.
Don’t use Isotrex Gel on any irritated areas of skin. For example if you
have cuts or grazes, or sunburn.
Don’t use too much Isotrex Gel on sensitive areas of skin such as the
Isotrex Gel can cause skin irritation when used with other medicines
used to treat acne. If your skin becomes irritated, reduce the amount of
times you use Isotrex Gel, or stop using it until the irritation goes away.
Stop using Isotrex Gel all together if the irritation does not go away.
Using Isotrex Gel can make your skin more sensitive to sunlight.
When you are using Isotrex Gel you need to:
 protect your skin from the sun. You can do this by using sunscreen and
wearing clothes to stop you getting sunburnt
 avoid using sun beds (sun lamps) or spending a long time in the sun.
➔ If you do get sunburnt, stop using Isotrex Gel until your skin is better.
Important information about some of the ingredients of Isotrex Gel
Isotrex Gel contains butylated hydroxytoluene (E321). This can cause local
skin reactions e.g. contact dermatitis, reddening or flaking of skin. It can
also cause irritation to your eyes and mucous membranes such as the
lining of your nose.
Other medicines and Isotrex Gel
Tell your doctor or pharmacist if you are taking any other medicines,
if you’ve taken any recently, or if you start taking new ones. This includes
medicines obtained without a prescription.
In particular, tell your doctor or pharmacist:
 if you are using benzoyl peroxide (another acne treatment). If used at the
same time, it may make Isotrex Gel less effective. You may need to use
these medicines at different times of the day (for example, one in the
morning and the other at bedtime).
 if you are using any other acne treatment. If used at the same time, it
may make skin irritation worse. If your skin becomes very irritated, you
may need to use Isotrex Gel less often or stop using it for a short period
to allow your skin to recover and then re-start treatment. Stop treatment
and see your doctor if skin irritation does not improve.
➔ Check with your doctor or pharmacist if you think any of these may
apply to you.
