How many doses of lisiniopril did you take? 2? 4? or did you take this med over a period of years?
What did you doc say?
What did your pharmacist say?
Why are you asking us?
I don't mean to sound nosey, but there can be many, many answers to your question...and as I said in my first post, "It depends".

Just because you may feel faint or feel like passing out doesn't mean it IS the lisinopril. Other conditons can cause this also...what other symptoms are you experiencing? And perhaps, more importantly, why do you think you were given the wrong dose?
