IMPORTANT WARNING

For all patients:

Vismodegib should not be taken by women who are pregnant or who may become pregnant. There is a risk that vismodegib will cause loss of the pregnancy or will cause the baby to be born with birth defects (physical problems that are present at birth).

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with vismodegib and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or visit the manufacturer's web site to obtain the Medication Guide.

Do not donate blood while you are taking vismodegib and for at least 7 months after your treatment.

Do not share vismodegib with anyone else, even someone who has the same symptoms you have.

Talk to your doctor about the risk(s) of taking vismodegib.

For female patients:

If you can become pregnant, you will need to avoid becoming pregnant during your treatment with vismodegib. You must have a negative pregnancy test within 1 week of the start of your treatment. You must use acceptable forms of birth control during your treatment and for at least 7 months after your treatment is completed. Your doctor will tell you which forms of birth control are acceptable.

If you think you are pregnant, you miss a menstrual period, or you have sex without using birth control while taking vismodegib or within 7 months after your treatment, call your doctor immediately.

For male patients:

You must use a condom with a spermicide every time you have sexual contact with a female who is pregnant or able to become pregnant while you are taking vismodegib and for 2 months after your treatment. Tell your doctor immediately if you have had unprotected sex with a woman who can become pregnant or if you think for any reason that your partner is pregnant.

WHY is this medicine prescribed?

Vismodegib is used to treat basal cell carcinoma (a type of skin cancer) in people with cancer that has spread to other parts of the body. Vismodegib is also used to treat basal cell carcinoma that cannot be treated with surgery or radiation or has come back after surgery. Vismodegib is in a class of medications called hedgehog pathway inhibitors. It works by blocking the action of a protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells and may help shrink tumors.

HOW should this medicine be used?

Vismodegib comes as a capsule to take by mouth. It is usually taken once a day with or without food. To help you remember to take vismodegib, take it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vismodegib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the capsules whole; do not split, chew, or crush them.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
