My doctor prescribed Zoloft 50MG for anxiety for me. I took 1/2 a pill on Monday morning and by the afternoon, I was having major panic attacks, tightness in the chest and nervousness. I ended up in the hospital overnight. They ran all kinds of tests to make sure my heart is ok and it is. How long will it take to get that pill out of my system? That medicine apparently does not work for me. I've also tried Celexa before, it had the same kind of symptoms but not as intense.
