The co-pays vary according to your insurance plan. Interferon -either PegIntron or
Pegasys are high and only available at full
price -- that is there is no generic -- so you pay whatever the company charges. Ribavirin is now available in generic and is much more reasonable than co-pegasys or the Schering version. Then like nygirl said, you may need other medicines that are pricey if your blood counts tank. And then there are the hidden costs of lotions that cannot be ignored.
