rifampin key facts
What dosages is rifampin available in?
rifampin is available as a 150 mg and 300 mg oral capsule.
What is rifampin used for?
rifampin is a rifamycin antibiotic that is used to treat:z
Tuberculosis (TB) Meningococcal carriers (when there’s bacteria living in the nose and/or throat, but not causing infection)
How does rifampin work?
rifampin is a rifamycin antibiotic. It blocks an enzyme (protein) the bacteria need to eventually make proteins, so the bacteria can’t grow and spread.
How do I take rifampin?
The dose of rifampin will be based on your age and weight. It is typically 5 mg/kg to 10 mg/kg (up to 600 mg per dose),once a day.
Is it safe for me to take rifampin?
rifampin is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you. You should not use this medication if you have a history of hypersensitivity to rifampin or any of the components, or to any of the rifamycins.
rifampin is contraindicated in patients who are also receiving ritonavir-boosted saquinavir due to an increased risk of severe hepatocellular toxicity. rifampin is contraindicated in patients who are also receiving atazanavir, darunavir,
fosamprenavir, saquinavir, or tipranavir due to the potential of rifampin to substantially decrease plasma concentrations of these antiviral drugs, which may result in loss of antiviral efficacy and/or development of viral resistance. rifampin is contraindicated in patients receiving praziquantel since therapeutically effective blood levels of praziquantel may not be achieved. In patients receiving rifampin who need immediate treatment with praziquantel alternative agents should be considered. However, if treatment with praziquantel is necessary, rifampin should be discontinued
weeks before administration of praziquantel. Treatment with rifampin can then be restarted one day after completion of praziquantel treatment. rifampin is contraindicated in patients receiving lurasidone. Concomitant use of lurasidone
with strong CYP3A4 inducers (e.g., rifampin) decreased the exposure of lurasidone compared to the use of lurasidone alone.
rifampin Common Side Effects
Common side effects of rifampin:
- Temporary change in color (orange/yellow) of body fluids and teeth
- Upset stomach
- Diarrhea
- Headache
- Fever
- Nervous system problems affecting energy, movement, thinking, or behavior
- Nerve pain or numbness
rifampin Serious Side Effects
Serious side effects are rare with rifampin. Contact your healthcare provider immediately if you experience any of the following.
- Allergic reaction: fever, rash, swelling of your lips or tongue, trouble breathing
- Serious bleeds: bruising easily, blood in the urine or stool, bleeding that’s difficult to stop
- Liver problems: loss of appetite, nausea or vomiting, dark urine, or yellowing of the eyes or skin
Effects of other drugs, drug classes and over-the-counter products on rifampin
The following medications may interact with rifampin:
- Antiretrovirals: Concomitant use is contraindicated.
- Drug metabolizing enzymes and transporters affected by rifampin include cytochromes
- P450 (CYP) 1A2, 2B6, 2C8, 2C9, 2C19, and 3A4, UDP-glucuronyltransferases (UGT)
- sulfotransferases, carboxylesterases, and transporters including P-glycoprotein (P-gp) and multidrug resistance-associated protein 2 (MRP2). Most drugs are substrates for one or more of these enzyme or transporter pathways and these pathways may be induced by rifampin simultaneously. Therefore, rifampin may increase the metabolism and decrease the activity of certain coadministered drugs or increase the activity of a coadministered pro-drug (where metabolic activation is required), and has the potential to perpetuate clinically important drug-drug interactions against many drugs and across many drug classes

If you have Medicare Part D or Medicare Advantage and none of the rifampin savings options are applicable or affordable for me, what can you do?
If you are insured with Medicare and the rifampin drug savings options are not applicable to you and still remain unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and after you have selected your state, it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
People who qualify for both Medicare and Medicaid are called ‘dual eligibles’.
If you are denied Medicaid for rifampin, and you are still unable to afford your copay or co-insurance element (for example if you are in the coverage gap or Donut Hole) then you may be eligible for a federal support program like Low Income Subsidy. To be eligible for Low Income Subsidy, you need to be a resident in one of the 50 States or the District of Columbia. You can check eligibility online at SSA Medicare D Extra Help. You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778).
I am uninsured or underinsured and none of the rifampin prescription saving options are applicable or affordable for me, what can I do?
If you are uninsured or underinsured (for example, rifampin is not covered by your plan) and the drug savings options are not applicable or still unaffordable, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. State Medicaid programs may cover the full cost of your medication.
If you are denied and all else fails, and if you have been prescribed rifampin for an FDA-approved indication, you can call the pharmaceutical company to see if they have any other assistance programs.
I am commercially or privately insured and none of the rifampin prescription saving options are applicable or affordable for me, what can I do?
If your medication is not covered by your plan, you can appeal your insurance company’s decision. Sometimes, a formal appeal can result in the drug being covered if it is deemed medically necessary.
If you cannot afford your copay contribution, then you can check Medicaid eligibility in your state by following the instructions at HealthCare.gov.
However, being privately insured might complicate your eligibility for Medicaid, as having private insurance may be considered in the financial eligibility assessment.
The government site is easy to use and you can select your state and it will navigate you to the appropriate contact point to make the application. If you qualify, state Medicaid may cover the full cost of your medication.
