Nifedipine
high blood pressure
"I've been taking Procardia XL for about 4 years now. My blood pressure stays fairly consistent. The only negative is that my feet and lower legs (knees down) swell a little when I'm standing for a long time. Fluids must accumulate in my lower extremities, I don't urinate as much when I'm standing, then urinate more than usual after I lay horizontal for a while. It does do a good job controlling the blood pressure and I only have to take 1 tablet a day."
