Had a patient today (Saturday) on 300mg irbesartan, 200mg celecoxib and 12.5mg hydrochlorothiazide daily. The HCT is vasodilatory rather than diuretic at that strength, but I'm interested in what threshold others are using as a cutoff to flag the combination. In this case the doc wasn't available, s

I think this past year has been the worst year of my life. In January I had a hypertensive crisis and checked into the ER with a BP of 213/110+ I’m pretty sure I was walking around like this for months not knowing it until my body told me something was wrong. Got put on Amlodipine as a first line me

I’ve been on a beta blocker since I was 25 (I’m 42 now) and my doc added valsartan about 3 years ago during the pandemic (during which time I was under a lot of stress and drank more alcohol). During the worst of that time I probably drank 10-15 drinks a week. Never been overweight, though, and regu

Then put me on a mild dose of HCTZ. Then about three years ago, he put me on carvidelol (the beta blocker). Long story short
Hi all, Writing for support. About 2 months ago I went to an unrelated GP appointment and a routine BP reading was taken. My BP was 180/120, several more were taken and it was still the same. I’m 27 female, 60kg, exercise regularly (mostly weights not cardio). I was quickly seen by a cardiologist an
A while ago I was put on Amlodipin and ended up in the ER after all bowel movements stopped.. according to my Dr, that was a very rare side effect he had personally never heard of. A month ago I was at the Dr office again after a few months without meds and my BP was 160/100. I was put on Valsartan
A few years ago, I went for a checkup during a time of high anxiety, I was even having panic attacks randomly and having insomnia. Obviously the readings were high 145/95 and was prescribed with valsartan. After that I got treatment for anxiety, and feel a lot better but now I am affraid to leave
Hi everybody I have tried all these three Losartan, Valsartan, Amlodipine. They all make me feel dizzy, stressed out, worried and depressed. Have someone had the same issues? Don’t know really what to do. I felt my health has really decreased since started on BP medicines. Thanks to all.God bless e
