For Angina "Ranexa made my angina symptoms worse. While on it, I got extremely out of breath at the smallest exertion, my heart raced, I was lightheaded, tired, had a headache, and pain in my stomach. When I went off of it, I felt better. I was taking 500 mg twice daily."

For Angina "Wish I could say it was effective, but I could not get past the side effects within the first week. I was light-headed, dizzy, faint, and did not feel much like myself. The doctor told me I needed an adjusting period. By the second week, it was too much, and I stopped taking the pills. So now I'm wearing a nitroglycerin patch and carry Nitro pills with me at all times. I'm on an EECP machine, which dilates vessels and supposedly encourages new vessel growth. This treatment is 5 days a week, 1 hour per session for 7 weeks."

For Angina "10 years ago, at age 46, I had a heart attack and quadruple bypass. 8 years ago, one stent, 4 years ago, 2 more stents. After over 2 weeks of nonstop angina, my only relief was sleeping. After 2 days of 500 mg Ranexa, I felt like a new man. I finally had relief from angina. Some bad side effects of lightheadedness, dizzy headache, and constipation. I had my first angina attack, nitro helps, but I thought I had it beat. I would gladly take the bad, but for myself, tolerable side effects for the angina (Medicaid covers my cost)."

For Angina "I was given Ranexa by my physician assistant for some minor chest pain. I took 4 doses of Ranexa (500 mg) as prescribed. I experienced dizziness, was lightheaded. That evening, about midnight, while I was in bed, I had uncontrollable diarrhea, headed to the bathroom, changed pajamas, and immediately had uncontrollable diarrhea again. Returning to bed, I experienced the uncontrollable diarrhea while asleep. I did not take any more and ended up in the hospital emergency room severely dehydrated. I was there two days with numerous tests. After this experience, I would never take this again. I destroyed the rest of the pills."
