There are quite a few anti-depressants available on the market. Some of them are more harsh than others. For instance, Wellbutrin is one of the most stimulating anti-depressants, so I would not recommend that for those with anxiety/panic attacks. Citalopram (Celexa) and Escitalopram (Lexapro) are considered more calming, and have a lower incidence of side effects, as far as the SSRI class of medications.
Many persons experience no side effects; some have mild, and some more severe. To lessen the chances of side effects, talk to your doctor about starting you on a sub-therapeutic dose of an anti-depressant. Then, slowly increase the dose every 10-14 days. This helps too.
Anti-depressants are a mixed bag. What works for you, might not work for me.
Good luck on finding the medication that works for you, with the least side effects. The best to you, Chris!... Chuck
