What is Isoniazid 100mg Used For?

Isoniazid 100mg is a medication mainly used to prevent and treat tuberculosis (TB). Tuberculosis is a serious infection caused by bacteria that mainly affects the lungs but can also impact other parts of the body. Isoniazid works by killing the bacteria that cause TB, helping to stop the infection from spreading.

How to Take Isoniazid 100mg?

Take Isoniazid 100mg exactly as your doctor prescribes. It’s usually taken once daily, on an empty stomach, which means you should take it 1 hour before or 2 hours after meals. If stomach upset occurs, you can take it with a small snack. Make sure to swallow the tablet whole, without crushing or chewing it.

Dosage Instructions

The usual adult dose for treating tuberculosis is 300 mg daily or 900 mg taken three times a week, based on the doctor’s advice. For children, the dose is typically based on body weight. Always follow your doctor’s instructions carefully to ensure effectiveness and reduce the risk of resistance.

Side Effects

Common side effects of Isoniazid include feeling tired, nausea, vomiting, and numbness or tingling in the hands and feet. It’s important to contact your doctor if these effects worsen or if you experience more serious side effects like yellowing of the skin or eyes, persistent nausea or vomiting, or unusual fatigue.

Drug Interactions

Isoniazid can interact with other medications, which can affect how well it works or increase side effects. Tell your doctor about all other medicines you’re taking, especially tyramine-rich foods like aged cheeses and cured meats, as these can increase your blood pressure when taken with Isoniazid.

Warnings

Be sure to discuss your medical history with your doctor before taking Isoniazid, especially if you have liver problems, kidney disease, or if you drink alcohol daily. Isoniazid can increase the risk of liver damage, so regular liver function tests may be required.

Storage

Store Isoniazid at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use and keep out of reach of children and pets.
