Rifapentine, sold under the brand name Priftin, is an antibiotic used in the treatment of tuberculosis.[2] In active tuberculosis it is used together with other antituberculosis medications.[2] In latent tuberculosis it is typically used with isoniazid.[2] It is taken by mouth.[2]

Common side effects include low neutrophil counts in the blood, elevated liver enzymes, and white blood cells in the urine.[3] Serious side effects may include liver problems or Clostridioides difficile associated diarrhea.[3] It is unclear if use during pregnancy is safe.[3] Rifapentine is in the rifamycin family of medication and works by blocking DNA-dependent RNA polymerase.[3]

Rifapentine was approved for medical use in the United States in 1998.[2] It is on the World Health Organization's List of Essential Medicines.[4] In many areas of the world it is not easy to get as of 2015.[5]
