Which type of b-blocker is best for treating social anxiety? what dose should i take?

Beta blocker: Propranolol is often used for social and performance anxiety doses range from 10-80mg you need to be cautious with beta blockers if you have a history of asthma

Social phobia: The greatest data exists for propranolol. This is often a twice or three times daily medication. Dosing can be quite variable due to individual difference in absorption. While nadolol has less data, I use it often as dosing is once a day. Beta blockers should be used cautiously in diabetics and asthmatics.
