IVer TELAPREVIR SUMMARY To treat HCV with Incevik Is not a trick. Just start it with PEG and Riba together. Treat for 12 weeks and see it get better. If negative at week 4. Its virtually a cure. Continue PEG and riba for sure. Till week 24. And then dash straight through the door.

IVer TELAPREVIR SUMMARY However, If the response is delayed. Do not be dismayed. For if less than a thousand by month 3. A cure can still be. Adhere to the stop rules at 4 and 12 weeks. This is important and so do not cheat. And you will see. This rule will keep you mutant free.

IVer TELAPREVIR SUMMARY AEs include rash, anemia and a sore bum. This is not fun. This make patients glum. And their physicians run. And so my friends, When treating with telaprevir there is no reason to quiver. Because its dam good at getting HCV Out of the liver.
