Hi I am 56 years old . I have high blood pressure , irregular heart beats benign, sinus events, allergic to sulfa medications, have asthma, hyperactive thyroid and graves disease, allergic to nifedipine. I have tried 6 pills , 4 different types of high blood pressure pills, nothing is working. been at the hospital from all of this. my pharmacist gave me the wrong pill to take. I just found out i am allergic to sulfa drug myself. I am at my wits end. Even the google search engine cannot help me. thanks
