Hello, My left eye began twitching about 2 weeks ago. It was just small spasms here and there and now it feels like it's twitching almost nonstop. It isn't painful, but it does feel irritated at this point. My lower lid and my upper lid are both twitching. My right eye is fine. I do not wear contacts and have no eye diseases, except near nearsightedness......which I sometimes wear glasses for. My medications include: prilosec 20mg/day and bupropion 150mg/day. What could be the problem? I've heard of some psych meds causing Extra-pyramidal side effects such as muscle spasms and twitching, but never heard of bupropion causing this. Could the med be causing this? I just began taking the burpropion again after a 4 month hiatus. The time the eye twitching began correlates with the time I began taking the med again.
