Zyprexa, Benadryl, Depakote,
and Seroquel have caused me to twitch
and feel like my skin is crawling an hour (or a few) after I take them. I feel as though there is an itch under my skin that I cannot scratch all over my body, and have involuntary movements in my limbs. It happened most severely with Seroquel (100 mg, if I am not mistaken). It did not happen every time I took each of the other medications, and gradually went away with Zyprexa. I was on Zyprexa for about 8 months... 5mg/day.
