Niazid Oral

Niazid Oral Uses

This medication is used with other medications to treat active tuberculosis (TB) infections or alone to prevent those who have a positive TB test from developing symptoms of TB. Isoniazid belongs to a class of drugs known as antibiotics that are active against tuberculosis.

How To Use Niazid Oral

Take this medication by mouth without food, usually once weekly to once daily, or as directed by your doctor. Depending on the type of TB you have, you may take isoniazid for 2-9 months.

Dosage is based on your age, weight, medical condition, and response to treatment. If you are taking a liquid form of this medication, carefully measure your prescribed dose using a medication-measuring device or spoon. Do not use a household spoon because you may not get the correct dose.

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 on the same day(s) of the week or at the same time(s) each day. If you are taking this medication several times a week, it may help to mark your calendar with a reminder.

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.
