Safely Buy Rebetol ( Ribavirin ) from Canada Prescriptions Plus.


Rebetol is a medication that contains the active ingredient ribavirin and is primarily used in combination with other antiviral medications, such as interferon or sofosbuvir, to treat chronic hepatitis C.

Rebetol is not effective when used alone for the treatment of hepatitis C.

Ribavirin works by inhibiting the replication of the hepatitis C virus, helping to reduce the viral load and improve liver function.

Ribavirin is typically used in combination therapy to increase the effectiveness of treatment and improve the chances of achieving a sustained virologic response (SVR), which means clearing the virus from the body.

Use and Dosage

Read the Medication Guide provided by your pharmacist before you start taking ribavirin and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Also, read the drug information for your other antiviral medication(s).

Take this medication by mouth as directed by your doctor, usually twice daily with food. Swallow this medication whole. Do not crush, break, or chew the capsules.

The dosage and length of treatment are based on your age, weight, medical condition, and response to treatment.

This medication works best when the amount of drug in your body is kept at a constant level. Take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.

Continue to take ribavirin and your other antiviral medication(s) for the full length of time prescribed, even if your symptoms disappear after a short time. Stopping any of the drugs too early may result in a return of the infection.

Drink plenty of water while being treated with this medication. Doing so will decrease the risk of serious side effects.
