Does propranolol effec night. time sleep?

It affects different people in different ways, it caused sleep disturbance and insomnia for me at 3x 40mg per day. It is a common side effect of the drug because it crosses the blood-brain barrier.

I know you already have a couple of great answers, I don't know what dose you're on But I have been taking the 80mg Sr. Capsules for almost 20 years and outside of being tired for the first few days, it has never bothered me at all. I started it for Migraine prevention which it works really well for me. But the best benefit I got is it really helped my anxiety a lot. But as said we all react differently to medications so all you can do is try it. But I have really had no side effects. Remember that also if you live in a real sunny place during that time of year you want to wear sunscreen it can cause you to sunburn easy photosensitivity.

Hi, as Masso has responded, it can do. However not in all cases. I didn't have any sleep disturbance when i was taking it. You won't know until you try it unfortunately
