Isoniazid is a medication commonly used in the treatment of tuberculosis (TB). It is an antibiotic that works by killing the bacteria that cause TB. Isoniazid is often used in combination with other medications to effectively treat TB and prevent the spread of the disease.

It is important to take isoniazid exactly as prescribed by your healthcare provider. This medication is typically taken once daily on an empty stomach, either one hour before or two hours after a meal. It is important to complete the full course of treatment, even if you start to feel better before the medication is finished.

While isoniazid is generally well-tolerated, like all medications, it can cause side effects. Common side effects of isoniazid include nausea, vomiting, and changes in liver function tests. It is important to notify your healthcare provider if you experience any side effects while taking isoniazid.

It is also important to be aware of potential drug interactions with isoniazid. Certain medications, such as antacids, can interfere with the absorption of isoniazid and should be taken at least one hour before or two hours after isoniazid. It is important to inform your healthcare provider of all medications you are taking before starting isoniazid.

Overall, isoniazid is an important medication in the treatment of TB and can be highly effective when taken as prescribed. If you have any questions or concerns about isoniazid or its use in your treatment, do not hesitate to speak with your healthcare provider.
