What it is
Isoniazid is an antibiotic medicine used for tuberculosis (TB). It works by killing the bacteria that cause TB. It is often used together with other TB medicines to treat active infections and alone to prevent infections in people who have been exposed.
What it's used for
Isoniazid is used for all forms of tuberculosis where the bacteria are susceptible. For active tuberculosis, it is given along with other anti-TB drugs to prevent drug resistance. It is also used as preventive therapy in people with a positive skin test or those at high risk of TB infection.
Common side effects
The most common side effects are peripheral neuropathy (numbness or tingling in the hands and feet), especially in people who are malnourished or have diabetes. Liver problems can also occur, so your doctor may monitor your liver function. Other side effects include seizures, confusion, and vision problems.
Important cautions
Do not take isoniazid if you have had a severe allergic reaction to it, including drug-induced hepatitis, or if you have acute liver disease. Watch for signs of severe skin reactions (rash, blisters, fever) and stop the medicine immediately if they occur. Avoid alcohol while taking isoniazid as it increases the risk of liver damage.
