Isoniazid - Dosage and How to Use

How should Isoniazid be used?

  • Do not stop taking your medication without checking with your healthcare professional.
  • This medication should be taken at least 30 minutes before food, on an empty stomach. However, if you are having stomach discomfort, you can take them after food instead.
  • Take your medication at the same time every day to maintain the same amount of medication in your body.
  • In children, the medication may be made into a mixture with water before taking.

What should I do if I miss a dose?

  • If you forget to take a dose, take it as soon as you remember. Then take your next dose at the usual time. Do not take two doses to make up for the missed dose.
  • It is important to complete the entire course of medication, even when you start feeling better during the treatment. This ensures that the tuberculosis bacteria in your body is fully killed.
