My doctor just gave me a prescription for zoloft 50 mg. I hae anxiety, depression and panic attacks. I read the information that came with the prescription and in addition to the side effects that are common to anti-depressants, zoloft came with a warning of something called "seratonin syndrome" that can be fatal and when I researched seratonin syndrome it can occur after taking just one dose of an SSRI. Well, I read that and had an immedite panic attack. I'm terrified to take it, but I need something as my anxiety is out of control. Has anyone else heard of this or have any experience with zoloft or SSRI's. How did they make you feel.
