Propranolol
"for me I'd say betablockers work well for performance/social anxiety.Reading the comments on this page sound so familiar to me.They will not stop you from being nervous but will bring you to a level where the physical aspects of your fear won't manifest ie pounding heart and trembling voice so once you start and realise this usually things will go better. I have found though that certain brands are better than others. I order mine online but yes they have been a lifesaver in certain situations such as introductions in meetings or big interviews etc. Normally for me around 30mg works well about 45 minutes to 1 and half hours before."
