Rifampicin
Summary
Rifampicin is an antibiotic used to treat serious bacterial infections like tuberculosis (TB), a lung infection. It's also used to prevent the spread of Neisseria meningitidis, a bacteria that can cause meningitis, an infection of the brain and spinal cord.
Rifampicin works by blocking bacterial RNA polymerase, which stops bacteria from making essential proteins. This kills the bacteria and is especially effective against diseases like tuberculosis and leprosy.
For adults with TB, the dosage is 10-20mg per kilogram of body weight daily, up to a maximum of 600mg. For preventing meningitis, the dosage is 600mg twice a day for two days. It's important to follow your doctor's instructions on how much to take and for how long.
Common side effects include a change in urine, sweat, and tear color, itchiness, headache, sleepiness, dizziness, and stomach problems like nausea, vomiting, cramps, loss of appetite, or diarrhea. More serious but rare side effects include flu-like symptoms, blood problems, liver problems, and severe allergic reactions.
People allergic to rifampin or other rifamycins should avoid this medication. Also, patients with liver disease or those taking medications that may interact adversely with rifampin should exercise caution. Always inform your healthcare provider about your complete medical history before starting treatment.
