Rifampicin is used to treat or prevent tuberculosis and other infections.
Take rifampicin regularly as directed. Take each dose on an empty stomach - one hour before or two hours after food. Keep taking it until the course is finished, even if you start to feel better.
Take the tablets and capsules with a glass of water.
Measure the liquid carefully with an oral syringe or measuring spoon. Shake the bottle well before measuring each dose.
Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time. If you often forget to take rifampicin, your infection may not be fully treated.
Rifampicin can react with many medicines, sometimes with severe results.
Tell your pharmacist or doctor about all medicines or treatments that you may be taking including vitamins, herbal products (e.g. St John’s wort) or recreational drugs.
Symptoms of liver problems including: yellow skin or eyes, itching, dark urine, pale bowel motions, abdominal pain
