Bedaquiline 

(bed ak' wi leen)

IMPORTANT WARNING:

Bedaquiline should only be used to treat people who have multi-drug resistant tuberculosis (MDR-TB; a serious infection that affects the lungs and other parts of the body and that cannot be treated with at least two of the medications that are usually used to treat the condition) when other treatments cannot be used. In a clinical study, there were more deaths among people who took bedaquiline than among people who did not take the medication. However, MDR-TB is a life-threatening disease, so you and your doctor may decide that you should be treated with bedaquiline if other treatments cannot be used.

Bedaquiline may cause serious or life-threatening changes in your heart rhythm. You will need to have an electrocardiogram (ECG; a test that measures the electrical activity of the heart) before your treatment and several times during your treatment to see how this medication affects your heart rhythm. Tell your doctor if you or anyone in your family has prolonged QT syndrome (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death) and if you have or have ever had a slow or irregular heartbeat, an underactive thyroid gland, low levels of calcium, magnesium, or potassium in your blood, heart failure, or a recent heart attack. Tell your doctor and pharmacist if you are taking any of the following medications: azithromycin (Zithromax), ciprofloxacin (Cipro), clarithromycin (Biaxin), clofazimine (Lamprene), erythromycin (E.E.S, E-Mycin, Erythrocin), gemifloxacin (Factive), levofloxacin (Levaquin), moxifloxacin (Avelox), and telithromycin (Ketek). If you develop a fast or irregular heartbeat or if you faint, call your doctor immediately.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with bedaquiline 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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

Talk to your doctor about the risks of taking bedaquiline.

WHY is this medicine prescribed?

Bedaquiline is used along with at least three other medications to treat adults with multi-drug resistant tuberculosis (MDR-TB; a serious infection that affects the lungs and other parts of the body and that cannot be treated with at least two of the medications that are usually used to treat the condition) that has affected the lungs. Bedaquiline should not be used to treat TB that mainly affects other parts of the body. Bedaquiline is in a class of medications called anti-mycobacterials. It works by killing the bacteria that cause MDR-TB.

HOW should this medicine be used?

Bedaquiline comes as a tablet to take by mouth. It is usually taken with food once a day for 2 weeks and then three times a week for 22 weeks. When you are taking bedaquiline three times a week, allow at least 48 hours between doses. Take bedaquiline at the same time of day and on the same days of the week every week. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bedaquiline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the tablets whole with plenty of water.

Continue to take bedaquiline until you finish the prescription and do not miss doses, even if you feel better. If you stop taking bedaquiline too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics. This will make your infection harder to treat in the future. To make it easier for you to take all of your medication as directed, you may participate in a directly observed therapy program. In this program, a healthcare worker will give you each dose of medication and will watch as you swallow the medication.

Are there OTHER USES for this medicine?

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