What is Zelboraf?

Zelboraf is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Zelboraf is used to treat melanoma (skin cancer) that has spread to other parts of the body or cannot be removed by surgery.

Zelboraf is also used to treat Erdheim-Chester Disease (a rare blood cancer).

Zelboraf is used only if your cancer has a specific genetic marker (an abnormal "BRAF" gene). Your doctor will test you for this gene.

Warnings

Zelboraf is used to treat melanoma, but this medicine can increase your risk of developing other types of skin cancer. Report any new or worsening skin lesions to your doctor right away.

Many drugs can interact with vemurafenib. Tell your doctor about all your current medicines and any you start or stop using

How should I take Zelboraf

Take Zelboraf exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Take Zelboraf with a full glass of water. You may take this medicine with or without food.

Take the medicine every 12 hours, at the same time each day.

Do not crush, chew, or break a tablet. Swallow the tablet whole.

If you vomit shortly after taking Zelboraf, do not take another dose. Wait until your next scheduled dose time to take the medicine again.

While using Zelboraf, you may need frequent blood tests to check your liver or kidney function.

To make sure this medication is not causing harmful effects, your skin condition will need to be checked often. Your heart function may also need to be tested with an electrocardiogram (ECG or EKG) on a regular basis. You may also need eye exams. Your cancer treatments may be delayed based on the results of these tests.

Your doctor may want to check your skin for several months after you stop using this medicine. Visit your doctor regularly.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if your next dose is less than 4 hours away. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

What should I avoid while using Zelboraf?

Avoid exposure to sunlight or tanning beds. Vemurafenib can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Vemurafenib can pass into body fluids (urine, feces, vomit). Caregivers should wear rubber gloves while cleaning up a patient's body fluids, handling contaminated trash or laundry or changing diapers. Wash hands before and after removing gloves. Wash soiled clothing and linens separately from other laundry.

Get emergency medical help if you have signs of an allergic reaction to Zelboraf (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).

Seek medical treatment if you have a serious drug reaction that can affect many parts of your body. Symptoms may include: skin rash, fever, swollen glands, flu-like symptoms, muscle aches, severe weakness, unusual bruising, or yellowing of your skin or eyes. This reaction may occur several weeks after you began using Zelboraf.

Stop using this medicine and call your doctor at once if you have:

  • skin changes - a new wart or lesion, a skin sore or red bump that bleeds or does not heal, or any change in the size or color of a mole;

  • unusual thickening of tissues under the skin on the palms of your hands or the soles of your feet;

  • a finger or fingers that feel tight or are bent inward;

  • fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out);

What other drugs will affect Zelboraf?

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
