I'm curious if anyone else has used this medication with any unwanted side effects. Uniretic is a combination BP drug that contains an ACE inhibitor and diuretic. I have been on this drug for about 6 months and seems to work well for lowering my pressure. I have read that it is used when other medications won't work. That is weird to me because I was started on this medication. After reading some of the common side effects, I can relate to quite a few of them. I started getting chronic sinus infections, lightheadedness alot, abdominal pain, back pain etc. None of the side effects are really debilitating or effect what I do really. Just wondering if anyone else has experience any side effects from uniretic.
