Isoniazid is available as oral tablets with a strength of 300mg. The medicine may be used as part of a treatment plan for tuberculosis or to prevent TB in certain people who have been identified as being at risk.

Uses of Isoniazid 300mg

For treatment of tuberculosis and some cases of latent TB infection isoniazid is widely used by physicians. In some cases TB can affect the lungs and other parts of the body. Treatment kills the TB bacteria and decreases the risk of getting sick or spreading disease.

But the right treatment depends on whether someone has latent TB infection, active TB disease or drug resistant TB. The healthcare professional should decide which medicines are appropriate and for how long.

How is isoniazid administered?

Take isoniazid exactly as directed by your doctor. Do not take a larger dose, take it more often or stop treatment without consulting your doctor. Treatment for TB can take months, so it is important to keep to the schedule you have been given.

Tell your doctor if you use other prescription medicines, over-the-counter products, vitamins, and supplements. This information may help your health care professional to determine possible interactions.

Important Safety Information

Isoniazid has a major safety warning due to the risk of serious, and sometimes fatal, liver damage. Patients should always consult their health care professional before beginning any treatment regarding their medical history.

Unusual tiredness, weakness, loss of appetite, nausea, vomiting, dark urine, yellow skin or eyes, pain in the upper-right part of the stomach — call your doctor right away. These symptoms may be signs of liver problems.

Your healthcare professional may also order laboratory tests to monitor your response to therapy and help identify potential problems early on.

Treatment for TB requires consistency. If patients miss doses or stop a course of treatment prematurely, TB bacteria can become resistant to medicines. This means that resistant TB can become harder to treat.
