Hello all thanks very much for your comments on this drug. I need...

No one can make the decision for you, but lesson 1 - you call the shots with your healthcare. The dry cough is internal HIVES down your father's throat from an allergic reaction to the Lisinopril (made from snake venom). Stop taking it, it will only get worse. You can see some other posts I've made, but marshmallow (the herb) will help clear up the throat after Lisinipril has been stopped. Find a complementary doctor who understands herbs and will use them before the more toxic drugs. Depending on how extreme your father's blood pressure is, herbs will often equal drugs in lowering blood pressure without the side effects. Do your research and take it with you to a new doctor. A few herbs to investigate are Grape Seed Extract, C12 Peptide (casien peptide). These are well documented on the internet - google "Blood Pressure Herbs" for more information. Weigh the pros and cons, work with your doctor, but bottom line - the doctors don't know everything, there's always something new to learn.
