How To Use Isoniazid-Rifamp-Pyrazinamide Oral

Take this medication by mouth without food, usually once daily or as directed by your doctor. This medication is usually taken for the first 2 months of a 6-9 month treatment course.

Dosage is based on your age, weight, medical condition, and response to therapy.

It is very important to continue taking this medication (and other TB medications) exactly as prescribed by your doctor.

This medication works best when the amount of drug in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it same time each day. Do not take more or less of this drug than prescribed or stop taking it (or other TB medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of TB bacteria to increase, make the infection more difficult to treat (resistant), or worsen side effects. If TB becomes resistant to this medication, it might also be resistant to other TB medications.

Your doctor may also direct you to take vitamin B6 (pyridoxine) to help prevent certain side effects (nerve problems) from isoniazid.

Inform your doctor if your condition persists or worsens.
