(rye ba vye' rin)IMPORTANT WARNING:
| Ribavirin will not treat hepatitis C (a virus that infects the liver and may cause severe liver damage or liver cancer) unless it is taken with another medication. If you have hepatitis C, your doctor will prescribe another medication to take with ribavirin. Take both medications exactly as directed. Ribavirin may cause anemia (condition in which there is a decrease in the number of red blood cells). Tell your doctor if you have ever had a heart attack and if you have or have ever had high blood pressure, breathing problems, any condition that affects your blood such as sickle cell anemia (inherited condition in which the red blood cells are abnormally shaped and cannot bring oxygen to all parts of the body) or thalassemia (Mediterranean anemia; a condition in which the red blood cells do not contain enough of the substance needed to carry oxygen), or heart disease. If you experience any of the following symptoms, call your doctor immediately: excessive tiredness, pale skin, headache, dizziness, confusion, fast heartbeat, weakness, shortness of breath, or chest pain. Keep all appointments with your doctor and the laboratory. Your doctor will order blood tests before you start taking ribavirin and often during the first 4 weeks of your treatment.Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ribavirin and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: http://www.fda.gov/cder/foi/label/2002/21511_Copegus_lbl.pdf.Talk to your doctor about the risks of taking ribavirin.For female patients:Do not take ribavirin if you are pregnant or plan to become pregnant.

Why is this medication prescribed?
Ribavirin is used with another medication called an interferon to treat hepatitis C. Ribavirin is in a class of antiviral medications called nucleoside analogues. It works by stopping the virus that causes hepatitis C from spreading inside the body. It is not known if treatment that includes ribavirin and another medication cures hepatitis C infection, prevents liver damage that may be caused by hepatitis C, or prevents the spread of hepatitis C to other people.
How should this medicine be used?
Ribavirin comes as a tablet, a capsule and an oral solution (liquid) to take by mouth. It is usually taken twice a day, in the morning and the evening, for 24-48 weeks or longer. Take ribavirin tablets with food. Take ribavirin capsules and oral solution with food, unless your doctor tells you that you may take ribavirin with or without food. In that case, be sure to take the medication the same way every day. It is best to take ribavirin at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ribavirin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake the liquid well before each use to mix the medication evenly. Be sure to wash the measuring spoon or cup after use each time you measure the liquid.
Your doctor may decrease your dose or tell you to stop taking ribavirin for a short time if you develop side effects of the medication. Call your doctor if you are bothered by side effects of ribavirin. Do not decrease your dose or stop taking ribavirin unless your doctor tells you that you should.
Other uses for this medicine
Ribavirin is also sometimes used to treat viral hemorrhagic fevers (viruses that can cause bleeding inside and outside of the body, problems with many organs, and death). In the event of biological warfare, ribavirin may be used to treat viral hemorrhagic fever that has been spread deliberately. Ribavirin is also sometimes used to treat severe acute respiratory syndrome (SARS; a virus that may cause breathing problems, pneumonia, and death). Talk to your doctor about the possible risks of using this drug for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
