Hi, I am on paliperidone metabolite shot once every three weeks for a year and eight months for psychosis and in the last 5 months was having some trouble breathing (shortness of breath) that goes in cycles. I have had shortness of breath in June 2013 first time, September 2013 second time, Dec 2013 third time and most recently March 3rd time for about a week at a time then the breathing problems go away and then come back again. I was wondering if shortness of breath is a known side effect of paliperidone shot like I have read in some schizophrenia forums written by people taking Invega Sustenna however my psychiatrist says always that it is only anxiety and that I require more meds for that, of which I am very hesitant to take. Should I switch medications maybe to Abilify? Thanks for your advice! Lindsay
