Ribavirin — Uses, Dosage, Side Effects & Safety

Drug class: Antiviral agent

Overview

Ribavirin is an antiviral medication used to treat certain viral infections, most commonly chronic hepatitis C (in combination with other medicines) and severe respiratory syncytial virus (RSV) infection in children and adults. It works by interfering with the replication of viruses, helping to reduce the amount of virus in the body and support the immune system in fighting the infection. Ribavirin is not effective against bacterial infections or the common cold. It is usually prescribed as part of a combination therapy, especially for hepatitis C, and is rarely used alone. Patients should be aware that ribavirin can cause serious side effects, including anemia and birth defects, and requires close monitoring by a healthcare provider. Key points: Ribavirin must not be used during pregnancy or by male partners of pregnant women due to the risk of severe birth defects. Regular blood tests are needed to monitor for side effects. Always take ribavirin exactly as prescribed and do not stop without consulting your doctor.
