An individual patient is always advised to consult their own physician. Looking for news on adverse reactions. This is a combination drug of a diuretic, hydrochlorothiazide and cozaar, an angiotensin receptor blocker.
Most side effects are due to the diuretic part, weakness, cramps, sun sensitivity, rash, etc.
The cozaar has a long list of occasional side effects, but is pretty symptom free in most patients. Hysaar is a combination of Cozaar and Hydrochlorthiazide. One is an angiotensin blocker and the other a diuretic. Other than a rise in blood pressure, there should be no problem with rapid stoppage.
