Candesartan
"I was prescribed this drug for migraine prevention,starting at 4mg and increasing the dosage by 4mg until I got to 16mg,if the migraines had not improved. They didn't and the side effects I experienced were extremely loud tinnitus at 8mg and above,hair loss,acid reflux resulting in the need to take omeprazole to counteract this,insomnia,hot sweats,nausea and weight gain of 22lb due to the fact of feeling so ill,I was unable to do regular exercise.Not a nice drug and did not reduce the severity of my migraine."
