Treatment may lead to the following side effects (see section 4):

• a reduced number of red blood cells (anaemia)
• a reduced number of platelets in the blood (thrombocytopenia) which are important to stop bleeding and work by clumping and clotting blood vessel injuries
• gastrointestinal problems.

Your doctor will do blood tests before each cycle of Lonsurf. You start a new cycle every 4 weeks. The tests are needed because Lonsurf can sometimes affect your blood cells.

This medicine is not indicated for use in children and adolescents below the age of 18 years. This is because it may not work or be safe.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

This includes medicines obtained without a prescription and herbal medicines. This is because Lonsurf can affect the way some other medicines work. Also some other medicines can affect the way Lonsurf works.

In particular tell your doctor or pharmacist if you are taking medicines used for treatment of HIV, such as zidovudine.

If the above applies to you (or you are not sure), talk to your doctor or pharmacist before taking Lonsurf.

Do not breast-feed if you are taking Lonsurf as it is not known whether Lonsurf passes into the mother's milk.

You must not become pregnant while taking this medicine. This is because it may harm your unborn baby.

You and your partner should use effective methods of contraception while taking this medicine. You should also do this for 6 months after you stop taking the medicine.
