http://www.medications.com/effect/view/22234 Just started 5MG Lisinopril once a day at bedtime (about a week). After looking up side effects, I found this site. I don't have hbp,never had. I was given this to help protect my kidneys (type1 diabetic). Side effects are: head ache, dizzy, muscle pain in Fri, 20 Jul 2007 16:39:39 -0400 http://www.medications.com/effect/view/22234?item=818 THIS IS SO CRAZY! I DECIDED TO CALL THE DOC TODAY AFTER 2 WEEKS OF 20MG A DAY FOR KIDNEYS (TYPE 1 DIABETIC ALSO) BECAUSE I'M FEELING HORRIBLE. I THOUGHT IT MIGHT PASS, BUT IT HASN'T YET! WHEN I SIT DOWN AND STAND UP REAL FAST, MY HEARING FEELS SO HOLLOW http://www.medications.com/effect/view/22234?item=818
