health problems including previous experience of
suicidal behaviour
• you have problems with your kidneys or your liver
• you are overweight
• you regularly drink a lot of alcohol

occurs within 7 to 10 days, and usually does not
require dose adjustment
• you are allergic to peanuts or soya.
Before, during and after treatment you will have
regular blood tests to check that there are no changes
to your kidneys, liver, cholesterol, and blood sugar
levels. If there are changes, your doctor may decide to
reduce the dose or stop treatment.

taking this medicine (see also section 4, Possible
Side Effects):
• Avoid exposure to the sun as much as possible, and
do not use sun lamps or UV beds at all. If exposure
to the sun is unavoidable, use a sunscreen of at least
SPF 15.
• Reduce the amount of intensive physical exercise as
pain in your joints or muscles may sometimes occur
as part of your treatment.
• You may find that your skin has become dry and
fragile. Avoid the use of cosmetic skin treatments, for
example do not apply anything that irritates the skin,
like peeling cream.
• Avoid wax depilation and cosmetic procedures
designed to smooth your skin, or to reduce scars
or aging signs (for example dermabrasion or laser
therapy) for at least 6 months after the end of
treatment. These procedures may cause skin scarring,
colour changes or peeling of the skin.
• Your eyes may become sensitive and dry throughout
the treatment. Wear glasses rather than contact
lenses. You may need to wear sunglasses to protect
your eyes from being dazzled.

with anyone, particularly not women.

your doctor will give you a lower dose.
