Hi, many years ago(!) i was prescribed Propranolol to help with my fear when i was taking driving lessons. It was very helpful. I don't think i could have passed my driving test without them. I was only taking 10mg, but i suppose the dose is dependent on the reasons why it is being used, and the level of anxiety needing to be treated. Hi, I was taking it as needed but have been taking it every day for the past month or two and I'm getting side effects similar to those I got when on Atenolol. It's important to keep taking it regularly every day, even if you don't have any symptoms. If you stop taking it your heart condition or blood pressure is likely to get worse, or your angina.
