Ischemic Stroke, Prophylaxis
"I had been taking Plavix without any side effects since experiencing transient ischemic stroke, but was advised by my doctor to try Aggrenox because a clotting test raised a question whether Plavix was effective. To start with I took one dose per day because I had had been advised to expect headaches until my body adjusted.  I felt my head was going to explode and got extremely nauseated. I took it for three days.  The headaches got worse, and I became nauseous, and my blood pressure went very high. I now list Aggrenox as a medication that I am allergic to because of the severe side effects. I continue to use Aspirin, Plavix and other medications to try to prevent strokes."
