GP says I would only feel increased anxiety for the first few days

It’s different for everyone,  but for me the increased anxiety didn’t really start to calm down for about 2-3 weeks.  Try and hang in there,  and maybe you can get something else prescribed like Xanax or Klonopin to help until the Zoloft has a chance to work it’s way in.  I am 3 1/2 weeks in and just starting to feel some relief, although I am still far from better.  It is a slow acting med,  but works well once it is in your system.  Good idea to try and talk to a psychiatrist.  They know more about side effects and things with this type of medicine than most GPs.  

I would agree. The first relief I found was 3 weeks... I know everyone is different but your doctor was wrong in saying 3 days..m that's way too short a time for sertraline to get to work x

Hi..

I'd say 3 to 4 weeks until the heightened anxiety stops. That's my personal experience. I was on 50mg for 2 years but recently had to increase to 75mg. The same side effects again but only for a week and not as bad as 1st time. Hang in there. You're not alone xx

Hi there, I also found there was a delay of about this period before the side affects started to kick in. One thing I have noticed on here is that everyone’s story is a little bit different. Hope you feel better soon 👍

Update! I’ve been feeling better in the evenings for the past few days, but the working days have been rough. I went to see a psychiatrist today and it was incredibly helpful. She said my GP was wrong, but that increased anxiety before SSRI’s kick in is very typical and likely what I’m experiencing. She doesn’t think Sertraline is for me, and is switching me over to Citalopram (Celexa) and Buspirone (Buspar). She said I have a head start because I’ve been taking Sertraline, but that the next two weeks will likely be rough. It’s at least nice to know a time frame. Thanks everyone for your help.
