WARNING: Isoniazid rarely causes potentially fatal liver disease. The risk is increased in people 35 years and older who use alcohol or illegal injection drugs or have long-term liver problems. Tell your doctor immediately if you develop symptoms of liver disease, including persistent nausea/vomiting, severe stomach/abdominal pain, unusual weakness/tiredness, dark urine, yellowing eyes/skin. Your doctor should order liver function tests while you are taking this medication.

USES: Isoniazid treats active tuberculosis (TB) infections. It also prevents active TB infections in people who may be infected with the bacteria. Isoniazid is an antibiotic that stops bacterial growth. It does not work for viral infections like the common cold or flu. Unnecessary use of antibiotics can lead to decreased effectiveness.

HOW TO USE: Take this medication by mouth on an empty stomach as directed by your doctor. If using the liquid form, measure the dose using a special measuring device/spoon. Do not use a household spoon. If you take antacids containing aluminum, take this medication at least 1 hour before the antacid. Take this drug at evenly spaced intervals to keep the medicine at a constant level in your body. Continue taking this medication until the full prescribed amount is finished, even if symptoms disappear. Stopping too early may result in a return of the infection and make it more difficult to treat. Your doctor may also recommend taking vitamin B6 (pyridoxine) to help prevent certain side effects from isoniazid.

Isoniazid may interact with foods containing tyramine/histamine, causing increased blood pressure, flushing of the skin, headache, dizziness, or fast/pounding heartbeat. Follow a special diet while taking this medication. Tell your doctor if your condition persists or worsens.
