Sulfonamides symptoms and conditions

I am so thankful for this site. I thought maybe it was just me. For one, I am allergic to Sulfa. My doctor knows this, as does my pharmacy. Still, they give me Lisinopril with Hydrochlorothiazide which you should NOT take if you have a sulfa allergy. From day one, I started with anxiety, agitation, nausea and what felt like a racing heart - though my pulse was normal. Day three I called the doctor and they said this was normal as my body "adjusted" to the medication. It has been over two weeks and the same thing keeps happening. I tried taking the meds at night to hopefully sleep through the side effects but no - it just kept me awake. I put another call in today and have yet to receive a return call from my doctor. I hope the doctor calls me and NOT the front desk girl because I have a lot of questions and concerns. Other symptoms I have been experiencing since I started Lisinopril are sever muscle cramping last for over 24 hours, dizziness, heavy chest/racing heart beat, restlessness and less frequent urination. For a 37 yo female who has to "potty" constantly, even throughout the night, going once in an 8+ hour period is not normal! The worst side effect though is definitely the anger and agitation. I feel like I am going to burst out of my skin or die banging my head against the wall. Last night I tossed and turned for 2 hours in agitation. I thought I would surely have a heart attack from the stress. Oh yeah my BP has NOT dropped at all (tho it fluctuates on or off the meds) on the 20 mg dose. Go figure.

My dad is 73 years old and has been in the hospital, rehab, nursing care, back to hospital, currently back in rehab since August 3, 2008. He was on Flomax which he was taken off of the first week in August after arriving to the hospital with low blood pressure and leg weakness to the point of being unable to walk. He had been taking it for years so doctors did not think Flomax the cause. However, once they ret'd him on Flomax he was unable to hold his head up when sitting in wheel chair (drooling) and very unresponsive. He also vomited and just stared at it, unable to respond to try to clean himself up. They took him off Flomax with some improvement. (He could hold his head up and respond.) His weakness declined to the point that he can no longer pee/poop without a diaper, can't swallow, can't speak (due to weakened vocal chords), and has no energy. He has a feeding tube. To date, they have not been able to pin point what dad's problem is. I noticed that on October 10, 2008, they returned him to Flomax. He again is sitting in wheelchair with head hanging down. No energy to do rehab. I have requested they take him off Flomax and LEAVE him off. I don't trust this drug. I think his long-term use of this drug could be what's killing my him.
