Dental and gum disorders, which may lead to loss of teeth, have been reported in patients receiving Pegasys and ribavirin combination therapy. In addition, dry mouth could have a damaging effect on teeth and membranes of the mouth during long-term treatment with the combination of Pegasys with ribavirin. You should brush your teeth thoroughly twice daily and have regular dental examinations. In addition some patients may experience vomiting. If you have this reaction, be sure to rinse your mouth thoroughly afterwards.

Indication for Polycythaemia vera and essential thrombocythaemia:

Pegasys must not be given to children and adolescents because no information is available on the use of Pegasys in this age group for these indications.

Indication for Chronic Hepatitis B and C:

Pegasys use is restricted to children and adolescents with chronic hepatitis C aged 5 years and above or children and adolescents with chronic hepatitis B aged 3 years and above. Pegasys must not be given to children below the age of 3 years because it contains benzyl alcohol and may cause toxic reactions and allergic reactions in these children.

• If your child has or has ever had a psychiatric disorder, talk to your doctor, who will monitor your child for signs or symptoms of depression (see section 4).
• When receiving Pegasys, your child may have slower growth and development (see section 4).

Do not use Pegasys if you are taking telbivudine (see “Do not use Pegasys”) because the combination of these medicines increases the risk of developing peripheral neuropathy (numbness, tingling, and/or burning sensations in the arms and/or legs). Therefore, the combination of Pegasys with telbivudine is contraindicated. Tell your doctor or pharmacist if you are being treated with telbivudine.

Tell your doctor if you are taking medicines for asthma, because the dose for your asthma medicine may need to be changed.

Patients who also have HIV infection: Tell your doctor if you are taking anti-HIV therapy. Lactic acidosis and worsening liver function are side effects associated with Highly Active Anti-Retroviral Therapy (HAART), an HIV treatment. If you are receiving HAART, the addition of Pegasys + ribavirin may increase your risk of lactic acidosis or liver failure. Your doctor will monitor you for signs and symptoms of these conditions. Patients receiving zidovudine in combination with ribavirin and alfa interferons are at increased risk of developing anaemia. Patients receiving azathioprin in combination with ribavirin and peginterferon are at increased risk of developing severe blood disorders. Please be sure to read the ribavirin package leaflet also.

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

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

When Pegasys is used in combination with ribavirin, both male and female patients must take special precautions in their sexual activity if there is any chance for pregnancy to occur, as ribavirin can be very damaging to an unborn baby:

• if you are a woman of childbearing potential who is taking Pegasys in combination with ribavirin, you must have a negative pregnancy test before treatment, each month during therapy and for the 4 months after treatment is stopped. You must use an effective contraceptive during the time you are taking the treatment and for 4 months after stopping treatment. This can be discussed with your doctor.
• if you are a man who is taking Pegasys in combination with ribavirin, do not have sex with a pregnant woman unless you use a condom. This will lessen the chance for ribavirin to be left in the woman’s body. If your female partner is not pregnant now, but is of childbearing potential, she must be tested for pregnancy each month during treatment and for the 7 months after treatment has stopped. You or your partner must use an effective contraceptive during the time you are taking the treatment and for 7 months after stopping treatment. This can be discussed with your doctor.

Ask your doctor or pharmacist for advice before taking any medicine. It is not known whether this product is present in human milk. Therefore, do not breast-feed an infant if you are taking Pegasys. In combination therapy with ribavirin, take notice of the respective informing texts of ribavirin containing medicinal products.

Refer also to the package leaflets of any other medicines that are used in combination with Pegasys.

Do not drive or use machinery if you feel drowsy, tired, or confused while taking Pegasys.

Pegasys contains benzyl alcohol, polysorbat 80 and sodiumThis medicine contains 5 mg benzyl alcohol in each pre-filled syringe which is equivalent to 10 mg/mL.

Benzyl alcohol may cause allergic reactions.

Benzyl alcohol has been linked with the risk of severe side effects including breathing problems (called “gasping syndrome”) in young children. Pegasys must not be given to premature babies, neonates or children up to 3 years old.

Ask your doctor or pharmacist for advice if you are pregnant or breast‑feeding, or if you have a liver or kidney disease. This is because large amounts of benzyl alcohol can build-up in your body and may cause side effects (called “metabolic acidosis”).

This medicine contains 0.025 mg of polysorbate 80 in each pre-filled syringe which is equivalent to 0.05 mg/mL. Polysorbates may cause allergic reactions. Tell your doctor if you have or your child has any known allergies.

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially “sodium-free”.

Your doctor has determined the exact dose of Pegasys, and will tell you how often to use it. If necessary, the dose may be changed during treatment. Do not exceed the recommended dose.

Pegasys to treat polycythaemia vera or essential thrombocythaemia is given alone with the recommended starting dose of 45 microgram once weekly subcutaneously and titrated usually in 45 microgram increments monthly to a maximum of 180 microgram once weekly subcutaneously.

Your doctor has determined the exact dose of Pegasys for your child and will tell you how often to use it. The usual dose of Pegasys is based on your child’s height and weight. If necessary, the dose may be changed during treatment. It is recommended that Pegasys pre-filled syringes be used for children and adolescents, as they allow for dose adjustments. Do not exceed the recommended dose.

The duration of combination treatment in children with chronic hepatitis C varies from 6 to 12 months depending on the type of virus your child is infected with and their response to therapy.

If you have the impression that the effect of Pegasys is too strong or too weak, talk to your doctor or pharmacist.
