angina pectoris prophylaxis
"My doctor prescribed this medicine due to on-going chest pain. I have now been taking it for 1 week and have a headache everyday. Nothing seems to help stop them. I have taken aspirin, Tylenol and even acetaminophen with codeine for relief and so far none have worked. The headache is constant throughout the day and is throbbing and causes dizziness. The good side is the chest pain has gone away. I'm considering stopping this medicine as the headaches are pretty bad."
