About Ribavirin

Ribavirin is an antiviral medicine from the nucleoside analogue group. It slows down how fast some viruses, including the hepatitis C virus, copy themselves inside the body. It comes as tablets, capsules and a liquid to swallow, and there is also a form given into a vein. It is a specialist medicine: it is started and checked by a hospital or liver clinic team, with regular blood tests. It can seriously harm an unborn baby, so strict pregnancy rules apply to both women and men who take it.

Who should not take it, or should take care

• Do not take it if you are pregnant or could become pregnant and are not using effective contraception. It can cause birth defects or the death of an unborn baby.
• Women who could become pregnant need a negative pregnancy test before starting, regular pregnancy tests during treatment and after it ends, and effective contraception during treatment and for several months after the last dose. Your doctor will tell you exactly how long.
• Men: ribavirin can damage sperm. Do not take it if your partner is pregnant or planning a pregnancy. Use a condom, and you and your partner must use effective contraception during treatment and for several months afterwards.
• Do not breastfeed while taking it.
• Do not take it if you have had a heart attack or other severe heart disease recently, or if you have a blood disorder such as sickle cell anaemia or thalassaemia.
• Do not take it if you are allergic to ribavirin.
• People with advanced liver disease (for example, yellow skin and fluid in the tummy) should not take it with interferon medicines.
• Tell your doctor if you have kidney problems, any heart problem, past anaemia, high blood pressure, breathing problems, or bleeding from the stomach or gut.
• Tell your doctor if you have ever had depression or other mental health problems, thoughts of suicide, or problems with alcohol or drugs.
• Tell your doctor if you have HIV, have had or are waiting for an organ transplant, or have diabetes, thyroid, eye, lung, pancreas or other liver disease, gout or sarcoidosis.
• Children and teenagers: growth may slow during treatment, and in some young people this may not fully recover.
• Older people should talk to their doctor before starting.

Medicines and drinks that can interact

• Didanosine (an HIV medicine): not recommended with ribavirin
• Zidovudine and stavudine (HIV medicines): ribavirin may make them work less well, and zidovudine raises the risk of anaemia
• Other HIV medicines: there is a higher risk of serious problems such as lactic acidosis and liver failure, so a specialist must check them together
• Azathioprine (an immune-suppressing medicine): a higher risk of severe blood problems when used with peginterferon
• Interferon and peginterferon medicines, and other hepatitis C medicines, which are often used with ribavirin; read the leaflets for those medicines too
• Ribavirin can stay in the body for a long time after you stop, so tell any doctor or pharmacist you have taken it before starting a new medicine, including ones you buy yourself

Always tell your doctor and pharmacist about every medicine, supplement and herbal product you take.

Using it safely

• Take it exactly as your specialist tells you. Do not change the dose or stop taking it without talking to them first, even if you get side effects.
• Take it with food.
• Swallow tablets and capsules whole. Do not break or crush them. If a damaged tablet touches your skin, wash it with soap and water; if powder gets in your eyes, rinse them with water.
• Shake the liquid well and use the measuring device that comes with it. Wash the device after each use.
• If you forget a dose, check the leaflet or ask your pharmacist. Never take two doses to make up for a missed one.
• Drink plenty of fluids.
• Go to all your blood test appointments. They check for anaemia and other problems.
• Avoid alcohol, as it can make liver disease worse.
• Look after your teeth: brush well, see a dentist regularly, and rinse your mouth if you are sick.
• It may make you feel drowsy, dizzy or confused, and the medicines taken with it can also affect you, so wait until you know how you react before driving or using machines.
• Keep it in its original container, out of the reach of children. Return unused medicine to a pharmacy; do not flush it.

Common questions

Why are the pregnancy rules so strict?
Ribavirin can cause serious birth defects or the loss of a baby, and it can also damage sperm. That is why both women and men taking it must use effective contraception during treatment and for some months after, and women need regular pregnancy tests. Your doctor will tell you exactly how long to keep using contraception.

Can ribavirin cure hepatitis C on its own?
No. It must always be used with other hepatitis C medicines. WHO says the newer direct-acting antiviral tablets can cure more than 95% of people, and a specialist decides whether ribavirin is also needed.

Why do I need so many blood tests?
Ribavirin often lowers the number of red blood cells (anaemia) and can affect other blood cells and the liver. Blood tests before and during treatment let your doctor change the dose or stop it if needed.

Is ribavirin used for Crimean-Congo haemorrhagic fever (CCHF)?
It has been used, but in 2025 WHO said the evidence that it works for CCHF and Lassa fever is not strong enough and removed it from its Essential Medicines List for these fevers. Anyone with signs of these fevers needs urgent hospital care, where specialists decide on treatment.

Can I drink alcohol while taking ribavirin?
It is best to avoid alcohol. Alcohol can make liver disease worse.
