Greetings Doctor, I am currently have HBP and my Dr. has me on 40mg Lisinopril Once daily, my last visit showed a spike in my BP due to possible treatment of Low Testosterone Injection treatment. I have a Urologist monitoring my blood because of the T level treatment, my original T level was 135 with the injections if went to almost 500. Anyway my primary Dr. added the chlorthalidone to my med s to assist the lisinopril, it did help bring my BP down to the upper 120 s to lower 130 s however one of the side effects was flushing and impotence, which reading about this chlothalidone appears to be a side effect. So I went off this med for a week and my flushing and impotence disappeared. Is there another diuretic I can take that will not give me these side effects ?
