I suppose the social anxiety medication that comes to mind first is valium. Valium is in a group of drugs called benzodiazepines. It influences chemicals in the brain that may have become impaired and lead to anxiety. Among its other uses are the treatment of agitation, shakiness, and hallucinations during alcohol withdrawal and the relief of certain kinds of muscle pain.
Of course there are so many caveats attached to using valium that many people are put off. For example you are advised not to use Valium if you are pregnant as birth defects may occur in an unborn baby. It is not recommended that you take this social anxiety medication if you have any breathing problems, glaucoma, kidney or liver disease, or a history of depression, suicidal thoughts, or addiction to drugs or alcohol. You are advised not drink alcohol while taking Valium as this medication can increase the effects of alcohol.
There are alternative drugs such as Phenergan but they carry warnings also.
