if you can find an antidepressant med that works for you, it will help a lot to reduce or stop panic attacks and anxiety
but some of these meds are very expensive
in australia, several leading psychiatrists now prescribe generic prozac as their antidepressant of first choice
they say its proven to be safe, having been used all round the world for a long time
a few highly promoted new antidepressants are quietly taken off the market after problems become apparent during the first year 
also there isnt any conclusive proof that the new antidepressants work any better
doctors sadly are mostly influenced by drug company advertising and so prescribe the newest and therefore most expensive antidepressant meds, you are entitled to ask for a cheaper one
also if you are short of money, always tell the doc, dont be too proud. docs will often give you very cheap or free meds, such as sample packs
