Vasodilator symptoms and conditions

I started taking Lisinipril to lower my blood pressure about a month ago. since the beginning I felt sleepy, lack of energy, and soon started an almost constant cough and really horrible pain in my left hip/leg.
I had not found this forum at that time, but I did some research using the numerous medical books online. I came across two different pages about coughing and pain in the hip, both of them pointing independently to the same culprit: bradykinin, which happens to be a vasodilator. That is the way Lisinopril acts, lowering BP by dilating blood vessels. I have stopped taking it, and hope the damage to my leg is not permanent. It is really a dangerous drug and should be withdrawn immediately from the market.

Thank you to all who have posted here. My 16 yr old son was prescribed Levaquin on 12/7/04 by a PA who told me, "this is a great new drug we don't normally give to children, but at 16-- he's old enough". (This drug is not approved for ANYONE UNDER 18.) My husband picked up the meds and gave one 500 mg levaquin pill to my son. I arrived at work and started researching Levaquin. This site was the first to pop up. I called home too late-- he had already taken one dose. He has experienced many of the side effects. It is now 3 weeks later. I have not seen many teens experiences and most posting do not tell their age. I am trying everything that will help cleanse his system. He is drinking lots of spring water with magnesium, also everyday eating yogurt, grape juice, sweet potatoes, broccoli, and almonds. I have found these to be healing foods for myself. He is also taking MSM 1,000 mg. MSM is a vasodilator. He tried to take Slow-Mag, but it caused abdominal cramps. I would like more information about what to do, and other teens recoveries. My son is very active, plays several musical instruments and is in marching band (snare drum). Thanks to you all, he didn't take anymore of this poison. I am certain the outcome would have been devastating. One pill was one too many.
