Rifadin contains the active ingredient rifampin. It is a prescription antibiotic that belongs to a group of medications called rifamycins. Rifadin is mainly used to treat tuberculosis and to help prevent meningococcal disease in certain people who have been exposed to the bacteria.
Rifadin is used as part of a combination treatment for tuberculosis (TB) caused by susceptible strains of Mycobacterium tuberculosis.
Tuberculosis is a bacterial infection that most commonly affects the lungs, but it can also affect other parts of the body, including the lymph nodes, bones, kidneys, and brain.
Rifadin should not usually be used alone to treat active tuberculosis. It is generally combined with other anti-tuberculosis medications to improve treatment effectiveness and reduce the risk of the bacteria developing resistance.
When used as part of a complete TB treatment regimen, Rifadin helps kill or stop the growth of tuberculosis bacteria.
TB treatment usually lasts for several months. It is important to take Rifadin and the other prescribed TB medications consistently for the entire treatment period.
Stopping treatment too early or frequently missing doses may allow the infection to return and can increase the risk of drug-resistant tuberculosis.
Rifadin is also used to eliminate Neisseria meningitidis bacteria from the nose and throat of people who carry the bacteria without symptoms.
This use is particularly important for certain people who have had close contact with someone diagnosed with meningococcal disease. Eliminating the bacteria can help reduce the risk of spreading it to other people.
Rifadin is used for prevention in these situations. It is not used to treat active meningococcal meningitis or another active meningococcal infection.
Preventive treatment may be recommended for people who have had close or prolonged contact with someone with meningococcal disease.
This may include household members or other people who have had direct exposure to the infected person’s respiratory or oral secretions.
A healthcare provider or public health professional will determine whether preventive treatment is necessary based on the type and timing of exposure.
Rifadin works by interfering with an enzyme that bacteria need to make RNA.
Specifically, Rifadin inhibits bacterial DNA-dependent RNA polymerase. Without normal RNA production, bacteria cannot make the proteins they need to grow and reproduce.
This action helps stop bacterial multiplication and allows the infection to be controlled.
Rifadin is one of the key medications used in many standard tuberculosis treatment regimens.
Depending on the type of TB and whether the bacteria are resistant to certain medications, treatment may include Rifadin together with medications such as isoniazid, pyrazinamide, and ethambutol.
The exact combination and length of treatment depend on factors such as the location and severity of the infection, drug susceptibility results, previous TB treatment, and the patient’s response to therapy.
Healthcare providers may perform blood tests and other monitoring during Rifadin treatment, particularly when it is used for several months.
Monitoring may include liver function tests and tests to determine how well the infection is responding to treatment.
Patients being treated for tuberculosis may also require sputum testing, imaging, or other follow-up tests.
Take Rifadin exactly as prescribed and complete the full treatment regimen.
Missing doses or stopping treatment without speaking with your healthcare provider can make tuberculosis more difficult to treat and may contribute to antibiotic resistance.
Rifadin is usually taken by mouth on an empty stomach, at least 1 hour before or 2 hours after a meal, unless your healthcare provider gives you different instructions.
Take Rifadin with a full glass of water. Try to take each dose at the same time every day to maintain consistent medication levels.
Antacids can reduce the absorption of Rifadin.
If you need to take an antacid, take Rifadin at least 1 hour before the antacid. Ask your healthcare provider or pharmacist if you are unsure how to separate your medications.
Swallow Rifadin capsules as directed.
If you cannot swallow the capsules, speak with your healthcare provider or pharmacist. A specially prepared oral liquid formulation may be an option. Do not open or alter the capsules unless your healthcare provider or pharmacist specifically tells you how to take your particular product.
For adults being treated for tuberculosis, the usual Rifadin dose is 10 mg/kg once daily, up to a maximum of 600 mg per day.
Rifadin must be used together with other appropriate tuberculosis medications. It should not normally be used alone to treat active tuberculosis because doing so can quickly lead to bacterial resistance.
For children with tuberculosis, the Rifadin dose is based on body weight.
A commonly recommended dose is 10 to 20 mg/kg once daily, up to a maximum of 600 mg per day.
The exact dose and treatment duration depend on the child’s weight, age, type of tuberculosis infection, and overall treatment plan.
For adults who need preventive treatment after close exposure to meningococcal disease, the usual Rifadin dose is 600 mg every 12 hours for 2 days.
Children receive a weight-based dose. Your healthcare provider or public health team will determine the correct amount based on the child’s age and weight.
Rifadin is used in this situation to help eliminate Neisseria meningitidis bacteria from the nose and throat. It is not used alone to treat active meningococcal meningitis.
The length of Rifadin treatment depends on why you are taking it.
For tuberculosis, Rifadin is usually taken as part of a combination treatment regimen for several months. For meningococcal prevention, treatment is much shorter and is usually completed over 2 days.
Take Rifadin for the full prescribed treatment period, even if you feel better.
Take Rifadin exactly as prescribed and avoid missing doses.
Missing doses or stopping tuberculosis treatment early can allow the bacteria to return and may increase the risk of drug-resistant tuberculosis.
Do not change your dose or stop Rifadin without speaking with your healthcare provider.
If you miss a dose of Rifadin, take it as soon as you remember unless it is almost time for your next scheduled dose.
If your next dose is due soon, skip the missed dose and continue with your regular schedule.
Do not take two doses at the same time or take extra Rifadin to make up for a missed dose.
If you miss several doses, especially during tuberculosis treatment, contact your healthcare provider because your treatment plan may need to be reviewed.
Rifadin (Rifampin) is available in the following forms and strength:
Rifadin can cause allergic or hypersensitivity reactions in some people.
Seek urgent medical attention if you develop:
Serious hypersensitivity reactions can occasionally affect other organs, including the kidneys or blood cells.
Rifadin can cause liver injury, which may range from mild increases in liver enzymes to serious hepatitis or liver failure.
The risk may be higher in people who already have liver disease or who take other medications that can affect the liver.
Contact your healthcare provider promptly if you develop symptoms such as:
Your healthcare provider may check your liver function before and during treatment, especially if you have existing liver problems or require prolonged therapy.
Avoid or limit alcohol while taking Rifadin, especially if you have liver disease or are taking other medications that may affect the liver.
Alcohol may increase the risk of liver problems during treatment.
Tell your healthcare provider if you have kidney disease.
Rifadin has rarely been associated with serious kidney problems, including inflammation of the kidneys, acute tubular injury, and acute kidney failure. These reactions have occurred more often during intermittent treatment or when Rifadin is restarted after an interruption.
Contact your healthcare provider if you notice decreased urine output, blood in the urine, swelling, or unexplained fatigue.
Rifadin can interact with many medications because it increases the activity of certain liver enzymes that break down drugs.
This can lower the amount of other medications in your body and make them less effective.
Important interactions may occur with:
Tell your healthcare provider about all prescription medications, over-the-counter products, vitamins, supplements, and herbal products you use before starting Rifadin.
Rifadin can make hormonal contraceptives less effective, including birth control pills.
Ask your healthcare provider about using an additional or alternative non-hormonal method of contraception while taking Rifadin.
Visual disturbances have been reported in people taking Rifadin.
Tell your healthcare provider if you develop blurred vision, changes in eyesight, or other new visual symptoms during treatment.
Rare cases of myopathy, which can cause muscle pain or weakness, have been reported with Rifadin.
Contact your healthcare provider if you develop persistent or unexplained muscle weakness, tenderness, or pain.
Tell your healthcare provider if you experience numbness, tingling, or weakness in your arms or legs.
These symptoms should be evaluated, particularly if you already have nerve problems or are taking other medications that may affect the nervous system.
Tell your healthcare provider if you are pregnant, think you may be pregnant, or plan to become pregnant.
Rifadin may be used during pregnancy when the expected benefits outweigh the potential risks. When used during the final weeks of pregnancy, Rifadin may increase the risk of bleeding in the mother or newborn, and vitamin K may sometimes be considered.
Do not stop tuberculosis treatment during pregnancy without speaking with your healthcare provider.
Rifadin passes into breast milk.
Your healthcare provider will weigh the benefits of treatment against any potential risk to the nursing infant and determine whether breastfeeding is appropriate during therapy.
Take Rifadin exactly as prescribed and avoid unnecessary interruptions.
Certain serious reactions, including kidney problems and flu-like reactions, may be more likely when Rifadin is taken intermittently or restarted after treatment has been stopped.
If you miss several doses, contact your healthcare provider before restarting your usual treatment schedule.
Your healthcare provider may monitor your:
Regular monitoring is especially important during long-term treatment or if you have liver disease, kidney disease, or take other medications that interact with Rifadin.
If you miss a dose of Rifadin, take it as soon as you remember unless it is almost time for your next scheduled dose. If your next dose is due soon, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time or take extra Rifadin to make up for a missed dose. If you miss several doses, especially during tuberculosis treatment, contact your healthcare provider before restarting your regular schedule. Missing doses can reduce treatment effectiveness and may increase the risk of drug resistance.
Avoid alcohol while taking Rifadin because combining alcohol with Rifadin may increase the risk of liver problems. You should also check with your healthcare provider before using other medications, supplements, or herbal products that may affect the liver. Rifadin interacts with many medications, so tell your healthcare provider about everything you take before starting treatment.
The length of Rifadin treatment depends on why you are taking it. When Rifadin is used to treat tuberculosis, treatment usually lasts for several months and Rifadin is taken together with other tuberculosis medications. When Rifadin is used to prevent meningococcal disease after close exposure, treatment is much shorter and is usually completed over 2 days. Take Rifadin for the entire prescribed treatment period, even if you begin to feel better. Stopping treatment too early may allow the infection to return and can increase the risk of antibiotic resistance.
Alcohol should generally be avoided while taking Rifadin. Both alcohol and Rifadin can affect the liver, so drinking alcohol may increase the risk of liver injury. Talk with your healthcare provider if you have questions about alcohol use during treatment, especially if you have liver disease or take other medications that can affect the liver.
Yes. Rifadin should generally be taken on an empty stomach, either 1 hour before or 2 hours after a meal, with a full glass of water. Food can reduce or delay the absorption of Rifadin, so taking it away from meals helps your body absorb the medication properly. Follow your healthcare provider’s instructions if you have been given a different dosing schedule.
