Re: Lisinopril & Hyzaar taken together . .
Maybe not contraindicated but possibly wasteful.
It's a three drug combination: lisinopril, losartan and thiazide.
The lisinopril is an ACE inhibitor that prevents the formation of angiotensin-2: if it is doing it's job then there is no need for an angiotensin-2 blocker.
If, on the other hand the lisinopril has stopped working necessitating the ARB (losartan), then perhaps the lisinopril could be done away with.
I wouldn't take both.
If the Hyzaar is stopped than an added precription for HCTZ, the thiazide diuretic, is wise.
