Rifampicin/isoniazid/pyrazinamide, also known as rifampin/isoniazid/pyrazinamide, is a medication used to treat tuberculosis.[2] It is a fixed dose combination of rifampicin, isoniazid, and pyrazinamide.[2] It is used either by itself or along with other antituberculosis medication.[2] It is taken by mouth.[2]

Side effects are those of the underlying medications.[2] These may include poor coordination, loss of appetite, nausea, joint pain, feeling tired, and numbness.[3] Severe side effects include liver problems.[4] Use in those under the age of 15 may not be appropriate.[4] It is unclear if use in pregnancy is safe for the baby.[4]

Rifampicin/isoniazid/pyrazinamide was approved for medical use in the United States in 1994.[4] It is on the World Health Organization's List of Essential Medicines.[5] The wholesale cost in the developing world is about US$3.93 a month.[6] In the United Kingdom a month of treatment costs the NHS about 39.51 pounds.[7]

Medical uses

The hope of a fixed-dose combination pill is to increase the likelihood that people will take all of three medications.[8] Also, if people forget to take one or two of their drugs, they might not then develop resistance to the remaining drugs.

Dosage

The defined daily dose is not established.[1]

Society and culture

It is manufactured by Aventis.[citation needed]
