What is the antibiotic Priftin prescribed for?

Priftin is an antibiotic prescribed 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 doctor.

There are some people that should not take Priftin?

You should not take Priftin if you have:

• a history of allergic reaction to any of the rifamycins (e.g., rifampin and rifabutin)

• It is very important to take your medicines exactly as prescribed by your doctor for the entire time that you are being treated. It is especially important not to skip doses. Otherwise, TB can return.

• If you begin having severe and/or constant diarrhea, stop taking Priftin immediately and contact your doctor for treatment.

• Priftin has been shown to interact with certain drugs (protease inhibitors) used to treat HIV-infection.

• If you have a history of poor nutrition, alcoholism, diabetes, or you are a teenager; your doctor may want you to add vitamin B6 as a supplement to your diet.

• Priftin may affect the reliability of birth control pills, so other methods of birth control should be used while taking Priftin.

• If you are in the late stages of pregnancy, your doctor may check your blood for clotting ability.
