From what I've read stuttering and anxiety can go together. If this has never happened to you before it may very well be the med. I would recommend telling your Dr you want to get off of this med and try something different. This is your decision of course. If it's not helping your anxiety and actually making it worse along with the stuttering it may be time to get off this med. You've given it more than 6 weeks, which most Drs recommend.
Yes, the stuttering should go away when you quit this med. Give it a little while though. I've taken a couple of meds that made me want to move my mouth or lick my lips all the time. My Dr told me to get off them and once I did those weird side effects went away.
Anxiety can manifest itself in so many different ways in my experience with it. I have had 'symptoms' come up over the years that I had not previously dealt with before, which defintely can be confusing at times.
Why not talk to your doctor about this? If the Zoloft was tolerated at the lower dose and you think it was working, then maybe that can be discussed. For me, side effects with medications like Zoloft tend to subside after a bit, but I do notice them more whenever the dose is adjusted.
Are you also currently in counseling as well for your anxiety? For me, this was the most important step I took. Combined with the SSRI, it helped me to lay out a path to long term relief from it....keep us posted!
Okay, first of all, I am not a doctor. But I can tell you my own experiences with these meds. I am on several medications for anxiety and depression, some of them are in the same 'family' of meds you are taking. And, yes, I have noticed some stuttering, but mostly when I am excited about something and try to talk too fast. I have been on these meds for about a month, and I do see the stuttering becoming less and less. For me, I think it is just part of my body adjusting to the new mix, and that it will go away. All I can tell you is that maybe the same will happen for you, and if not and it's really bothersome, go back to your doctor. Blessings - Blu
