Frequently asked questions about VIEKIRA PAK-RBV2

Why do I need ribavirin (RBV)?

VIEKIRA PAK-RBV is prescribed to treat a specific type of chronic genotype 1 hepatitis C.  Your Hep C doctor has decided that it is the most appropriate treatment for you. With your prescription, you will receive VIEKIRA PAK tablets in daily blister packs, as well as ribavirin tablets in a bottle.

You will receive both of these together in the monthly carton of VIEKIRA PAK-RBV.

What should I do if my ribavirin dose is changed?

Your Hep C doctor may adjust your dose of ribavirin (blue tablets) based on the results of your blood tests, or if you experience any side effects, and will contact you to tell you about this change. They will provide you with instructions on how many ribavirin tablets you need to take each morning and evening.

If your dosage of ribavirin changes, please ask for a new dosage card to be filled in and given to you when you collect your next month of VIEKIRA PAK-RBV.

Even if your ribavirin dose changes, your VIEKIRA PAK dose (pink and beige tablets) will not change. Always follow the advice of your Hep C doctor or nurse, and contact them if you don’t understand.

Return any left-over ribavirin tablets to a pharmacist for disposal.

What should I do if I am not sure about my ribavirin dosage?

Always check with your Hep C doctor, nurse or pharmacists if you are unsure about what dose of ribavirin you should be taking.

If you do not have a dose card, ask for one to be filled in and given to you when you collect your medicine to help you remember your ribavirin dosage.

Why do I have left-over ribavirin tablets after I have finished my VIEKIRA PAK tablets?

The VIEKIRA PAK dose (pink and beige tablets) does not change, but ribavirin (blue tablets) can be prescribed in different doses. Depending on your prescribed dose, you may have some ribavirin tablets left in the bottle after you finish the VIEKIRA PAK tablets. You can return any left-over ribavirin tablets to a pharmacist for disposal.

Can I take VIEKIRA PAK-RBV whilst pregnant or if planning to become pregnant?2

No. Do not take VIEKIRA PAK-RBV if you are pregnant or if you are trying to get pregnant.

Ribavirin may cause birth defects and/or death of an unborn baby.

For men, do not take VIEKIRA PAK-RBV if your female partner is pregnant or planning on becoming pregnant. Extreme care must be taken to avoid pregnancy during treatment and for 6 months after finishing treatment with ribavirin. Two reliable forms of contraception must be used during this time. This applies both to women and to men who have partners of childbearing age. Talk to your doctor or nurse about this.

Can I start, stop or change contraceptives while on VIEKIRA PAK-RBV?2

Some oral contraceptives (containing ethinyloestradiol) should not be taken during treatment with VIEKIRA PAK-RBV. Your Hep C doctor or nurse can give you information on alternative contraception if necessary.
