I have copd - emphysema but I also have a severe tremor that affects my whole body. I was prescribed 40mgs of propranolol (starting dose) to try. I took 10mgs and it caused severe breathing difficulty. If had taken the 40mgs I would have ended up in hospital. I was wondering if anyone here is on the safer beta blockers such as metoprolol or atenolol? Both of these are used for tremors and safer up to approx 100mgs for copd sufferers.
