I’ve been on propanol 40mg twice a day since September this year. I was opus on them for my anxiety mainly the rapid heartbeat. I’m also on fluoxetine and I was given propranolol to help me till fluoxetine kicked in. But I’m prediabetic and have been reading that propranolol can cause diabetes by raising blood sugar and I’m really scared now I just want to stop taking it but scared my heart rate will go through the roof! I’ve been reading through previous posts and now I’m scared as I did read someone said once you’re on propranolol you can’t come off! But what if it’s affecting my blood sugars I will have to come off. I feel fine on them I just am so scared about this blood sugar thing. I was planning to stay on them maybe a few more months but now just want to stop as I’m so scared of this side effect
