I've been dealing with this for months now and it's driving me nuts!!! I have had tremor before but when I went from 10 mg of celexa to 20 I started getting tremor in my hands and legs etc. pretty much all over starting about a week after upping the dose to 20. Constant, 24/7. Never stops. It started to ease up after 6 WEEKS of constant tremor. Then I decided I wanted to come off the stuff so I started lowering the dose slightly and then after 2 weeks of that I upped it again and I got the tremors back. I have them right now again and I'm lowering my dose again. I want to try to get to 10 again because I hate this stuff. 20 mgs makes me feel so apathetic and depressed and empty plus all the tremors are scaring me about neurological problems and damage. I saw a neurologist who wasn't concerned but man, even my psychiatrist acted like it was no big deal. When you're practically feeling like a jackhammer all day and night that's not nothing. Now my left hand is weaker than my right so I don't know what's going on.
When I grip something in my right hand I see a slight tremor that goes away and when I grip something in my left there's a much more pronounced tremor that also starts to get better, but I feel all over tremors and weirdness. It's like I had 8 cups of strong coffee all the time. I take xanax and it helps for a short time.
I read that this is a very common thing for SSRI's but I had tremor in 2005. I am trying to find ut if I was on Zoloft then because I did take that for about 6 months then and again for a year in 2010. I'd get tremor on and off for a few days or a week or two and it would go away. My mom also has a tremor her whole life on and off, bad nerves like me. I don't know if I'm predisposed to this and the SSRI's just exacerbate it or what.
