What are the pros and cons of a 20 year old male with slight social anxiety being perscrived to 50mg zoloft?

I would say give it a try. Take it for 3 months or so, and if the side effects are unbearable or if it isn't working, you can stop. I currently take 50 mg of Zoloft (sertraline) and I am so happy on it. It has been 9 years now. I don't have any side effects (I may have had some when I first started, I don't remember). I drink about once a week and I have never had any problems with that.
