For High Blood Pressure "Have had high blood pressure for a number of years. Now 68, been on labetalol 200mg 2x a day and enalapril 10mg 2x a day. Have high epinephrine and metanephrine. Endo doc switched my medication to doxazosin 4mg at night. I have taken it for only 2 days, pulse went up to 120 and blood pressure went up, not down. I'm still on the enalapril dose. I feel dizzy, sick to my stomach, and have a headache mostly in the back of my head. The doctor talks about raising the doxazosin dosage to 8mg, there's no way, I weigh 155 lbs and I'm 5'9"."

Cardura (doxazosin) for High Blood Pressure "Took 1 8mg Cardura daily. Experienced dizziness and nausea for the first 3 days but later adjusted to the medication and maintained pressure around 120/80. On doctor's advice, Cardura discontinued and replaced with alternative medication due to excessively fast pulse/heart rate up to 100/s after 6 months on Cardura."

For Benign Prostatic Hyperplasia "I started on 1 mg for a couple of days, then 2 mg for a couple of days. I was on 4 mg only 4 days and 8 mg for just two. At that point, I was so dizzy I could barely drive. I was actually getting motion sickness as a driver, and I drive probably 25,000 miles a year. I could actually feel my prostate shrink, but had some horrible side effects. My semen dried up to nothing, and as far as ejaculating during sex-forget it. I took the drug only a total of two weeks, and I've been off it for 10 days, and still can't get an erection. Fortunately, the dizziness cleared up after about 3-4 days after stopping. I can't find any documentation at all to show how long the drug persists in the average person."

For High Blood Pressure "The penny has only just dropped after talking to my daughter- a senior nurse. I couldn't understand why I felt as if I was about to faint and be woozy and nauseous when I stood up or walked. I put this down to a painfully torn ligament in my knee and the ever-so-long time it was taking to heal enough for me to walk more than a few meters. I also suddenly couldn't read the captions on TV, and my neck ached for no apparent reason. This was put down to eye drops for glaucoma. This is one of three medications for high blood pressure. I will stop taking this 2 mg dose and hopefully feel normal again. My blood pressure varies enormously, so I can't say with certainty whether this has helped or not from a medical perspective."
