Why is this medication prescribed?

Rifampin is a broad-spectrum antibiotic that is primarily prescribed for the treatment of bacterial infections, especially those caused by Mycobacterium tuberculosis, which is the bacterium responsible for tuberculosis (TB). Rifampin is often used in combination with other antibiotics to treat TB and prevent its recurrence.

In addition to TB, rifampin may be prescribed for other bacterial infections, such as:

• Mycobacterium avium complex (MAC) infections: Rifampin is sometimes used in combination with other antibiotics to treat infections caused by these bacteria.
• Meningococcal carriers: Rifampin may be used to eliminate Neisseria meningitidis bacteria in individuals who are carriers of the bacteria and may spread it to others.
• Staphylococcal and streptococcal infections: In certain cases, rifampin may be part of the treatment for infections caused by these bacteria.

How should this medicine be used?

It’s crucial to follow your healthcare provider’s instructions and the prescription label when taking rifampin. Here are general guidelines for the use of rifampin:

• Dosage: The dosage of rifampin will depend on the specific condition being treated. It is important to take the medication exactly as prescribed by your healthcare provider.
• Administration: Rifampin is usually taken by mouth with a full glass of water. It can be taken with or without food. If stomach upset occurs, taking rifampin with food may help alleviate this side effect.
• Consistency: Try to take rifampin at the same time(s) every day to maintain a consistent level of the medication in your bloodstream.
• Completion of Treatment: Complete the entire course of rifampin as prescribed by your healthcare provider, even if your symptoms improve before the medication is finished. Stopping the medication prematurely may lead to the development of antibiotic-resistant bacteria.
• Interactions: Inform your healthcare provider about all medications (prescription and over-the-counter), supplements, and herbal remedies you are taking, as rifampin can interact with various drugs.
• Avoid Alcohol: Limit or avoid alcohol consumption while taking rifampin, as it may increase the risk of liver toxicity.
• Follow-up and Monitoring: Your healthcare provider may schedule regular follow-up appointments to monitor your response to treatment and assess for any potential side effects. Liver function tests may be conducted periodically.
• Birth Control: If you are using hormonal contraceptives, such as birth control pills, discuss alternative or additional contraceptive methods with your healthcare provider, as rifampin may reduce their effectiveness.

Always consult with your healthcare provider if you have any questions or concerns about rifampin or its usage, and never hesitate to seek medical attention if you experience unusual or severe side effects.

Other uses for this medicine

• While Rifampin is primarily known for its role in treating tuberculosis, it may also be used in certain other situations.
• Rifampin is sometimes used in combination with other antibiotics for the treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA).

What special precautions should I follow?

When taking rifampin, it’s crucial to follow your healthcare provider’s instructions carefully and be aware of certain precautions to ensure the medication’s effectiveness and minimize potential risks. Here are some important precautions to consider:

Dietary Instructions for Rifampin:

• Food Interactions: Rifampin can interact with certain foods and reduce its absorption. To maximize absorption, take rifampin on an empty stomach at least one hour before or two hours after a meal.

What should I do if I forget a dose?

What to Do if You Forget a Dose:
