It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests will be needed before starting this medicine, every week for the first 8 weeks during treatment, every 2 weeks for the next month, and then every 3 months after to check for liver problems.

Using this medicine while you are pregnant can harm your unborn baby. If you are a woman who can bear children, your doctor may give you a pregnancy test before you start using this medicine to make sure you are not pregnant. Birth control pills may not work as well to prevent pregnancy when used with this medicine. Use another form of birth control (eg, condoms, spermicide) along with your pills during treatment with this medicine and for at least 1 month after the last dose. Male patients with female partners should use an effective form of birth control during treatment and for at least 1 week after the last dose. If you think you have become pregnant, tell your doctor right away.

Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.

Talk with your doctor before using this medicine if you plan to have children. Some men and women who use this medicine have become infertile (unable to have children).

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
