Priftin is an antibiotic used to treat pulmonary tuberculosis (TB). Priftin must only be used in combination with at least one other anti-TB drug prescribed for your condition. You must take Priftin twice a week for 2 months with no less that 3 days (72 hours) between doses, plus other daily medications as directed during this intensive phase of the treatment. It is critical that you not miss even one dose of Priftin or your other medications during this 2-month intensive phase of treatment to make sure that TB disappears from the saliva and to make sure that TB does not return.

After the first 2 months, you must take Priftin once a week in combination with at least another anti-TB drug prescribed for your condition.

Experience using Priftin with HIV - positive patients is limited. If you are HIV - positive, you may require more frequent doses; consult your health care provider.
