I took inderal for cardiac PVCs for a while (in early 2015) but stopped because of nighttime hallucinations (my cardiologist and I agreed it was best). In later 2015 (October or November, I forget) I was put on it again for migraines and the hallucinations started again after a month give or take, so again my neurologist took me off it. I have not been on any medications (other than my IUD, Motrin, and vitamins). In the last few weeks the nighttime hallucinations came back. Is it possible that the inderal altered something to cause this or could it be something else?
