I have been diagnosed with major depression, PTSD and anxiety. I am currently taking Buspirone (15mg 1 po prn q TID) AND Effexor XR (300mg q day). Mirtazipine has also been added to my medication regimen (I have yet to start this medication) and I have prescribed Prazosin (1mg q HS for night terrors/rarely taken). I have currently been having an increase in sweating (often excessive whereas others are not hot ), vision changes, constipation (approx. 10 days without BM) and now I am experiencing nocturnal leg cramps and leg twitching. Could these symptoms be related to these medications? I am 48 yrs old, and I have been thinking that the diaphoresis is related to hormonal changes? I am not sure as to what course of action I need at this time, but am worried that I may be developing serotonin syndrome.
