What Drug Rifampicin?
What is rifampicin for?
Rifampicin is a rifamycin antibiotic drug with a function to treat various infections, such as:
- tuberculosis (TB)
- leprosy
- legionnaires's disease
- brucellosis and serious staphylococcal infections
This medicine can also be given to carriers, ie people who may be infected but have no symptoms of infection caused by Haemophilus influenzae (which causes flu) and Neisseria meningitidis (which causes meningitis).
Rifampicin dosage and rifampicin side effects will be described further below.
How do I use rifampicin?
Rifampicin is a capsule that is consumed only by mouth. This medicine should be taken with a full glass of water on an empty stomach, 1 hour before or 2 hours after eating. Take rifampicin once a day to treat tuberculosis. Rifampicin is taken twice a day for two days to prevent the spread of the Neisseria meningitidis bacteria to others. Follow the directions for use on your prescription label carefully, and ask your doctor or pharmacist to describe any parts you do not understand. Take rifampicin exactly as recommended. Don't take more or less than the recommended level or take it more often than your doctor has recommended.
Tell your doctor or pharmacist if you are unable to swallow the capsules. Your pharmacist may change the dose of the capsule in liquid form for you as an alternative.
If you are taking rifampicin to treat tuberculosis, your doctor may recommend that you regularly take rifampicin for several months or more. Continue to use the rifampicin for the lifetime indicated on the prescription even if you feel better, and be careful not to miss a dose. Stopping rifampicin doses too early will put you at risk of infection, becoming drug resistant (resistant) and more difficult to treat. If you miss a dose of rifampicin, you may experience uncomfortable or serious symptoms when you restart using this drug.
How do you store rifampicin?
This medicine should be stored in the refrigerator. Don't freeze it. Other brands of this drug can have different storage rules. Pay attention to the storage instructions on the packaging of your product, or ask your pharmacist. Keep all medicines out of reach of children and pets.
