Pyrazinamide (peer-a-ZIN-a-mide) belongs to the family of medicines called anti-infectives. It is used, along with other medicines, to treat tuberculosis (TB).
To help clear up your tuberculosis (TB) infection completely, you must keep taking this medicine for the full time of treatment, even if you begin to feel better. This is very important. It is also important that you do not miss any doses.
Pyrazinamide is available only with your doctor's prescription, in the following dosage form:
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For pyrazinamide, the following should be considered:
Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to pyrazinamide or to ethionamide (e.g., Trecator-SC), isoniazid (e.g., INH, Nydrazid), or niacin (e.g., Nicobid, nicotinic acid). Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy—Studies on effects in pregnancy have not been done in either humans or animals.
Breast-feeding—Pyrazinamide passes into the breast milk in small amounts.
Children—Pyrazinamide has been used in children and, in effective doses, has not been reported to cause different side effects or problems in children than it does in adults.
Older adults—Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing pyrazinamide in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.
Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
To help clear up your TB completely, it is important that you keep taking this medicine for the full time of treatment, even if you begin to feel better after a few weeks. It is important that you do not miss any doses.
Dosing—
The dose of pyrazinamide will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of pyrazinamide. If your dose is different, do not change it unless your doctor tells you to do so.
Missed dose—
If you do miss a dose of this medicine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
