I never said, "Oh that is better". I said that it has a higher bioavailability and is considered slightly safer. Those are the facts. Of course, individuals have different responses to different meds. What gives me no trouble may give you side effects, and vice versa. I never said Valtrex is always better for all patients. No one can know that. I gave Katyw some known facts about the medications which she can use to discuss with her doctor and make her own decision. Indeed, money can be a huge issue. That said, a lower dose of a more effective but more expensive medicine can cost less than a higher dose of a less effective medicine. It depends on dosage and cost. It's worth looking into rather than dismissing out of hand without getting the facts. Famvir has also been effective in some cases. It, too, is worth looking into. I only mentioned Valtrex because it is the same drug (once it's in the system) as acyclovir. I wasn't trying to suggest a different drug, just that she look into the more bioavailable form of the same drug. Not everyone has kidney issues with Valtrex. It is a possibility, of course.
