Summary
Rifabutin is used to treat infections caused by certain bacteria, including Mycobacterium avium complex, which can cause lung infections. It's also used to prevent these infections in people with weakened immune systems, such as those with HIV.
Rifabutin works by stopping the growth of bacteria. It interferes with the bacteria's ability to make proteins, which are essential for their survival, effectively cutting off their food supply and leading to their death.
The usual starting dose of Rifabutin for adults is 300 mg once daily. It can be taken with or without food. Always follow your doctor's dosing instructions carefully and consult them if you have any questions.
Common side effects of Rifabutin include nausea, vomiting, and rash. These effects vary from person to person and are usually mild. If you notice any new or worsening symptoms, contact your doctor.
Rifabutin can cause a decrease in white blood cells, increasing infection risk, and may affect liver function. Avoid if allergic to it. Inform your doctor about all medications you're taking to avoid interactions.
