This medication is an antiviral used in combination with interferon to treat ongoing hepatitis C. Long-term hepatitis C infection causes liver swelling that can lead to serious liver conditions such as scarring, cancer, and organ failure. Ribavirin works by reducing the amount of hepatitis C virus in your body, which may help your liver recover. However, this drug is not a cure for hepatitis C infection, and it does not prevent the spread of Hepatitis C to others through sexual contact or blood contamination (e.g., sharing used needles).
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.
