Ive been taking citalopram for a few weeks now, I had some initial side effects such as mild headache and nausea but they subsided, until now. I get a killer headache when I take one now and occasional nausea, almost like motion sickness which I've never had. I also seem to randomly get a reaction to deodorant which I never had before, I dont know if developing sensitive skin is linked? Is it normal to get worsened side effects after the initial few weeks?
