ribavirin capsule - oral, Rebetol (cont.)
USES: This medication is an antiviral used in combination with interferon to treat ongoing hepatitis C.

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).OTHER This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional.
