I'm retired military and get 200mg monthly depo shots once a month from the my local Air Force Clinic. I have had good results but my last few shots I have started to get shortness of breath. I thought I was having a heart attack at one point, and went to a clinic and was checked out ok. This seems to occur the 2nd week after my injection, has anyone else had these issues, is this common? I feel great except these breathing set backs, the clinic gave me albuterol sulfate, which helps for a little bit.
