Be careful with these drugs, they can have all sorts of bad side effects. She has to face her anxiety, even if she is somewhat anxious. Medications can helo, but dont give too much. Just enough to help her to get a job, and from there, she can take steps towards socializing more and more and with a confident mindset, and with time, she will overcome her social anxiety. I would also recommend her seeing a therapist if she can. Medications can help but they have all sorts of side effects, especially in large doses, so i would suggest that you tell her to only use enough meds so that she can function somewhat socially, not to the point of causing depression or anything.
