migraine prevention
"I was put on atenolol, 50 mg daily, 27 years ago. Prior to that I also suffered debilitating migraines almost daily for many years. The atenolol controlled the BP and, in a complete surprise, eliminated the migraines.  In the following years, my doctor switched me to a newer BP medicine and the migraines returned. When I went back to atenolol the migraines went away. Atenolol has been one of the very best things ever to happen to me in terms of health."
