Rifampin (Rifadin®) is a medicine prescribed for treating tuberculosis or ridding the body of Neisseria meningitides (the bacteria that causes meningococcal infections, such as meningitis). Although most people tolerate this drug well, side effects are possible and may include common reactions like heartburn, nausea, and itching. However, rifampin is an older medication, so the specific statistics on how common these problems occur are fairly vague.
Because it can be difficult to predict whether you will develop any side effects while using rifampin, make sure to let your healthcare provider know if you experience anything that does not seem right. Serious side effects, such as fever, bloody diarrhea, and chest pain, are also possible and require immediate medical treatment.
