What is Rifater?
Rifater are antibiotics that prevent tuberculous bacteria from multiplying in your body.
Rifater is a combination medicine used to treat tuberculosis (TB) in adults and children at least 15 years old.
Rifater may also be used for purposes not listed in this medication guide.
You should not use this medicine if you have severe liver disease, an attack of gout, if you take certain antiviral medicines, or if you have a history of fever, chills, and joint pain or stiffness caused by isoniazid.
Rifater can cause severe liver symptoms, especially in people who are 35 and older. Your liver function will need to be checked often.
Call your doctor at once if you have: nausea, vomiting, upper stomach pain, weakness, tiredness, loss of appetite, or yellowing of your skin or eyes.
Tell your doctor about all your current medicines and any you start or stop using. Many drugs can interact, and some drugs should not be used together.
Avoid drinking alcohol.
Before taking this medicine
You should not use this medicine if you are allergic to isoniazid, pyrazinamide, or rifampin, or if you have:
severe liver disease;
an attack of gout; or
a history of fever, chills, and joint pain or stiffness caused by isoniazid.
Many drugs can interact and cause dangerous effects. Some drugs should not be used together with Rifater. Your doctor may change your treatment plan if you also use: atazanavir, darunavir, fosamprenavir, praziquantel, ritonavir, saquinavir, or tipranavir.
Serious and sometimes fatal liver problems may occur during treatment with this medicine or even months after you stop taking it. The risk of liver problems is highest in adults between the ages of 35 and 65.
Tell your doctor if you have ever had:
alcoholism (or if you drink alcoholic beverages every day);
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Rifampin can make birth control pills less effective. Ask your doctor about using a non-hormonal birth control (condom, diaphragm, cervical cap, or contraceptive sponge) to prevent pregnancy.
You should not breastfeed while using this medicine.
How should I take Rifater?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take this medicine on an empty stomach, at least 1 hour before or 2 hours after a meal. Take each dose with a full glass of water.
Your doctor may perform tests to make sure your tuberculosis is not resistant to this medicine. You may also need frequent eye examinations to check your vision.
Your liver function may need to be checked every month while you are taking this medicine, and for a short time after your last dose.
Rifampin may cause temporary discoloration of your teeth, sweat, urine, saliva, and tears (a yellow, orange, red, or brown color). This side effect is usually not harmful. However, soft contact lenses may be permanently stained if you wear them while taking this medicine.
Dark colored urine can be a sign of liver problems. Call your doctor if you have reddish-brown urine together with upper stomach pain, loss of appetite, and jaundice (yellowing of your skin or eyes).
This medicine may affect a drug-screening urine test and you may have false results. Tell the laboratory staff that you use Rifater.
Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Rifater will not treat a viral infection such as the flu or a common cold.
Your doctor may have you take extra vitamin B6 while you are taking Rifater. Take only the amount of vitamin B6 that your doctor has prescribed.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call 115. An overdose of Rifater can be fatal, especially when combined with alcohol.
Early symptoms of an overdose may include nausea, vomiting, stomach pain, lack of energy, headache, and itching. Later symptoms may include severe stomach pain, yellowing of your skin or eyes, body fluids that are dark brown or dark red-orange, swelling in your face, seizure, or loss of consciousness.
What should I avoid while taking this medicine?
Avoid drinking alcohol. It may increase your risk of liver damage.
Avoid taking an antacid within 1 hour after you take Rifater. Some antacids can make it harder for your body to absorb this medicine.
Avoid foods that are high in tyramine or histamine, listed below. Tyramine or histamine can interact with this medication and cause unpleasant side effects. These foods include:
beer or wine (especially red wine);
cheese (especially aged or processed cheeses);

What other drugs will affect Rifater?
Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
