How do I take/use this medicine?
Take Rifampicin exactly as directed by your doctor. Do not take more or less than instructed by your doctor.
Rifampicin is best taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will help improve the absorption.
Take it with a full glass of water. Try to take it at the same time each day.
Take Rifampicin at regular intervals as instructed by your doctor. Do not skip any doses. Continue to take it even when you feel better. You must complete the entire course of medicine. If you don't, the infection will not clear completely and will become harder to treat.
To make sure that you are completely cured of TB, it may be necessary for you to take Rifampicin for a few months depending on your condition and the combination of medicines used. Your doctor will advise you about how long you need to be treated. Make sure that you follow your doctor's instructions. Complete the entire treatment course.
What should I take note of while using/taking this medicine?
Inform your doctor if you have kidney or liver disease, an inherited condition known as porphyria, or if you regularly drink a lot of alcohol.
Alert your doctor if you are pregnant or breastfeeding.
For as long as you are being treated with Rifampicin, you will need to have regular blood tests to monitor your body's response to the medicine. Your doctor will advise you about how often you need to have blood tests.
By itself, Rifampicin cannot cure TB. Make sure that you take the other TB medicines given to you by your doctor.
What must I do to prevent spreading TB to other people?
TB is spread through the air, especially when you cough, sneeze or laugh.
You may still be able to infect others while undergoing treatment for TB. If your doctor has told you to stay at home so that you do not spread TB to other people, follow his instructions. You may need to sleep in a bedroom separate from your family members.
Always cover your mouth when you cough, sneeze or laugh.
If you use tissue paper, seal it in a plastic bag before you throw it away.
Above all, make sure that you take all your TB medicines exactly as instructed and complete the entire treatment course.
