Diovan HCT side effects

I have been taken diovan now for about 4 months and I have no complaints. on last week my doctor switch me to lisinop/hctz but after reading all the negative responses i rather continue paying the high cost medication.

For a year or so I took a HALF of a Diovan 320/HCT25 tablet
twice a day. It worked just fine. It controlled my blood pleasure. Now I am taking a Diovan 160/12.5 tablet twice daily
and I am experiencing new side effects that are very bothersome. My mouth is very dry and and a very bad taste in my mouth.
Question: Can there be any difference at all between taking half of the 320/25 and a whole one of 160/12/5 ?
Thank you. Erica

I have been on Diovan for about three months now, and it has lowered my blood pressure. Unfortunately, I am experiencing a side effect (I think) from the medicine. About eight months ago I had two inguinal hernias repaired. It was not until I started taking Diovan that I started having burning and a light pulling sensation in both areas. Is it possible that because the blood vessels in that area are being relaxed by the Diovan that I am having problems? My doctor thought it might be from an infection that is common with the mesh that is used. He prescibed an antibiotic, but this has done nothing to help. Any thoughts???? Thanks, Angelo in Kissimmee
