Pyrazinamide must be taken at regular intervals. Continue to take this medicine even when you feel better. Do not stop taking it unless instructed by the doctor.
Do not skip any doses. You must complete the entire course of antibiotic. If you don't, the infection will not be properly controlled.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
If you often forget to take your medicine, let your doctor and pharmacist know.

For as long as you are being treated with Pyrazinamide, you will need to have regular blood tests to monitor your body's response to the medicine. Your doctor will advise you about how often you need to have blood tests.
This medicine cannot cure TB. Make sure that you take the other TB medicines given to you by your doctor.
What must I do to prevent spreading TB to other people?
TB is spread through the air, especially when you cough, sneeze or laugh.
You may still be able to infect others while undergoing treatment for TB. If your doctor has told you to stay at home so that you do not spread TB to other people, follow his instructions. You may need to sleep in a bedroom separate from your family members.
Always cover your mouth when you cough, sneeze or laugh.
If you use tissue paper, seal it in a plastic bag before you throw it away.
Pyrazinamide may cause any of the following side effects: nausea, vomiting, loss of appetite, tiredness, joint and muscle pain.
If you develop rashes, breathlessness, swollen mouth or eyes, stop the medicine and inform your doctor quickly. These could be signs of an allergic reaction.
Some side effects may need immediate medical help. Alert your doctor quickly if you experience yellowing of the skin or eyes.
Inform your doctor if any of these side effects do not go away or are severe, or if you experience any other side effects.
Inform your doctor and pharmacist if you are taking any of these medicines:
- other TB medicines e.g. rifampicin
- medicines for gout e.g. sulfinpyrazone, probenecid
- medicines used in organ transplant or certain immune disorders e.g. ciclosporin
