• if you notice a change in your vision.
• if you develop symptoms associated with a cold or other respiratory infection (such as cough, fever or any difficulty in breathing).

During treatment your doctor will take blood samples regularly to check for changes in your white blood cells (cells that fight infection), red blood cells (cells that carry oxygen), platelets (blood clotting cells), liver function, glucose (blood sugar levels) or changes in other laboratory values.

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.

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 5 mg benzyl alcohol in each pre-filled syringe which is equivalent to 10 mg/ml.

Benzyl alcohol may cause toxic reactions and 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”).

Pegasys 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 is used alone only if you cannot take ribavirin for any reason

Pegasys given alone or in combination with ribavirin is usually given at a dose of 180 micrograms once a week.

The duration of combination treatment varies from 4 to 18 months depending on the type of virus you are infected with, on treatment response and whether you have been treated before. Please check with your doctor and follow the recommended duration of treatment.

Pegasys injection is normally taken at bedtime.

Use in children and adolescents

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. In chronic hepatitis B the duration of Pegasys treatment is 48 weeks. Please check with your doctor and follow the recommended duration of treatment. Pegasys injection is normally taken at bedtime.

Pegasys is intended for subcutaneous use (under the skin). This means that Pegasys is injected with a short needle into the fatty tissue under the skin in the abdomen or thigh. If you are injecting this medicine yourself, you will be instructed how to give the injection. Detailed instructions are provided at the end of this leaflet (see “How to inject Pegasys”).

Use Pegasys exactly as described by your doctor, for as long as prescribed by your doctor.

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

Combination therapy with ribavirin in chronic hepatitis C

In the case of combination therapy with Pegasys and ribavirin, please follow the dosing regimen recommended by your doctor.

Combination therapy with other medicines in chronic hepatitis C

In the case of combination therapy with Pegasys, please follow the dosing regimen recommended by your doctor and refer also to the package leaflets of any other medicines that are used in combination with Pegasys.

Contact your doctor or pharmacist as soon as possible.

If you realise you missed your injection 1 or 2 days after it was scheduled, you should inject your recommended dose as soon as possible. Take your next injection on the regularly scheduled day.

If you realise you missed your injection 3 to 5 days after it was scheduled, you should take your injection at the recommended dose as soon as possible. Take your next doses at 5 day intervals until you return to your regularly scheduled day of the week.

As an example: Your regular weekly Pegasys injection is on Monday. You remember on Friday that you forgot to take your injection on Monday (4 days late). You should inject your regularly scheduled dose immediately on Friday and take your next injection on Wednesday (5 days after your Friday dose). Your next injection will be on the Monday, 5 days later after the Wednesday injection. You are now back on your regularly scheduled day and should continue your injections every Monday.

If you realise you missed your injection 6 days after it was scheduled, you should wait and take your dose on the next day, your regularly scheduled day.

Contact your doctor or pharmacist if you need any help determining how to manage a missed dose of Pegasys.

Do not take a double dose to make up for a forgotten dose.

If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly (see details below). By reporting side effects you can help provide more information on the safety of this medicine.
