Ribavirin is an antiviral medication primarily used to treat viral infections, particularly hepatitis C and certain types of viral hemorrhagic fevers. It works by inhibiting the replication of viruses, helping to reduce their ability to multiply and spread in the body. This medication is often used in combination with other antiviral drugs to enhance its effectiveness. While Ribavirin can be beneficial, it may also cause side effects, including fatigue, anemia, and respiratory issues. Patients are usually monitored closely during treatment to manage any adverse reactions.
