Uses / Indications 

• Pulmonary tuberculosis (TB) as an element of combination therapy
• Extrapulmonary tuberculosis - lymph nodes, bones, joints, etc.
• The first two months of TB therapy are usually the most intense.
• Drug-sensitive TB in adults and children (dose adjusted)
• ⚠️ Pyrazinamide is never given by itself; it is always given with other drugs that fight TB.

 How It Works

• Pyrazinamide:
• Gets into cells of Mycobacterium tuberculosis
• It turns into pyrazinoic acid inside the bacteria.
• Works best in places with a lot of acid (such inside diseased cells)
• Stops TB bacteria from making energy and working on their membranes.
• When used together, it can shorten the length of TB therapy.

How to Use

• Take exactly as your doctor or the DOTS/TB program tells you to.
• Usually taken once a day with food
• Take the whole tablet with water.
• Take it every day at the same time.
• Don't skip doses, and finish the whole course.
• You may need to have blood tests done on a regular basis while you are getting therapy.

Side Effects

• Feeling sick or throwing up
