I also take Citalopram, but find I have that sensation with breakthrough anxiety. I am experiencing this since last week. I have been taking Citalopram for about 12 years.
I get the same symptoms coldness through me. Feels like I am loosing the plot alot worse than I was before I started taking them. Only on 10mg because very sensitive to medication. Took 20mg through my period time as that's when I am most depressed the effect was 10 x worse than 10mg. I have also found it effects my periods and have brusing all over my arms and legs anyone else get these.
I am sensitive to meds. It makes me worried that they may want to switch me to something else, which will just start me on the side effect trail again. I just don't know if I should work through this or try something new.
Sometimes the side effects are worse than the symptoms...especially if you're one of "us"...you know, the kind of people that are very sensitive to most medications.
If this is extremely bothersome ( which it sounds like it is ) go see a pharmacist or go back to your doctor. Either one will be able to help you choose a different medication. Of course only the doctor can prescribe a new one...but the pharmacist can help you find one that doesn't have those side effects...
