INDICATIONS

Copegus is an antiviral medication.

Copegus must be used together with an interferon alfa product (such as Pegasys, PegIntron, Sylatron, or Intron A) to treat chronic hepatitis C.

INSTRUCTIONS

Take exactly as prescribed by your doctor.

Ribavirin is not effective when used alone to treat hepatitis C. It must be used together with an interferon alfa product (such as Peg-Intron or Intron A) to treat chronic hepatitis C.

Take this medicine with food.

Use ribavirin regularly to get the most benefit.  Drink extra fluids while you are taking ribavirin to keep from getting dehydrated, especially during exercise or in hot weather.

Please consult your doctor to prescribe the required dosage.

The daily dose of COPEGUS is 800 mg to 1200 mg administered orally in two divided doses. The dose should be individualized to the patient depending on baseline disease characteristics (e.g., genotype), response to therapy, and tolerability of the regimen.
