I had been on Doxazosin for at least 4 years before stopping them in August this year.
I also had dreadful problems with Ramipril. I had complained that both made me ill over the years but the GP's will not listen, they just lecture that you need the drugs and must put up with some side effects..
Problems with Doxazosin :-.
Headaches, Sinus Pain, Upper Teeth Ache, Chronic Rhinitis, Blocked Nose, Constant Colds, Tinnitus, Blurred Vision, Stress Incontinence (it is not just for the ladies), Blood in Urine, Pain Passing Urine, Reduced Flow Rate, Generally Feeling Unwell.
I too would say that Doxazosin ruined my life
GP's prescribed, Nasal Spray, Antihistamine on repeat prescription, regular Antibiotics.
BP didn't change much when I stopped Doxazosin I keep a regular check on it. Headaches, Tinnitus, Rhinitus, Sinus and Teeth Pain, Stress Incontinence, went away, Flow Rate increased.
Still improving slowly, now I have to face the GP with the news, its worse than having to go to the Headmasters Office as a child.
