Drug Interactions With Valtrex
Valtrex is a drug that can potentially interact with a number of drugs such as cimetidine, tenofovir, and probenecid. The levels of Valtrex in the blood may be increased.
While this may not cause any problem in most cases and even the dosages need not be adjusted, but the risk of side effects will remain high and these interactions may aggravate symptoms if your kidney function is poor.
Under such circumstances, the doctor may have to readjust the dosages if this is the case.
Some of the drugs can have interactions when taken with Valtrex:
When Valtrex is taken with cimetidine, it can increase the levels of Valtrex in the blood. For most people, these interactions may not cause any problems and even the dosages of these medications need not be adjusted.
