Ribavirin is an antiviral medicine used for specific viral infections — most often severe respiratory syncytial virus (RSV) in infants and, historically, in combination with other drugs for hepatitis C. It comes as oral tablets, an inhaled aerosol, or IV in hospital settings. If someone mentions ribavirin, the main things to think about are effectiveness for certain viruses, a real risk of anemia, and strong pregnancy warnings.
Ribavirin is a nucleoside analogue: it interferes with viral RNA replication so the virus can’t reproduce well. Doctors may use it with other antivirals for complicated cases — for example, it was commonly paired with interferon for hepatitis C before newer direct-acting antivirals became standard. In infants with severe RSV, the inhaled form can be used in intensive care settings. For rare viral hemorrhagic fevers (like Lassa), ribavirin may be lifesaving when given early.
If you or a family member is prescribed ribavirin, ask why it’s needed, which form will be used, and what the expected benefits are. Different illnesses require different dosing strategies, so the exact dose and length of treatment will come from the treating clinician.
The most common major side effect is hemolytic anemia — red blood cells break down, which can make you tired, short of breath, or faint. Doctors will usually check your blood counts and liver tests on a schedule while you’re taking ribavirin. Tell your provider right away if you notice unusual tiredness, fast heartbeat, or dark urine.
Ribavirin is highly teratogenic: it can cause serious birth defects. Both people with female partners of childbearing potential and women who could get pregnant must use effective contraception during treatment and for six months after stopping. Men should also use condoms during treatment and for six months after. Don’t handle broken tablets or aerosolized drug if you are pregnant.
Other side effects can include cough (especially with inhaled forms), rash, nausea, and irritability. Some drug combinations increase risks — for example, combining ribavirin with certain immunosuppressants can worsen blood count problems. Always give your doctor a full list of medicines and supplements.
Practical tips: follow lab monitoring schedules, report symptoms early, avoid pregnancy during and six months after therapy, and never buy from unverified online sellers. If you miss a dose, follow the instruction from your prescriber or pharmacist — don’t double up unless told to do so.
