I called 911. They sent an ambulance. I told them my tongue and lips felt swollen. The ER took me right back to a room and gave me Benadryl. Watched me for an hour and let me go. The doctor said I’d had prednisone before without a problem but to discontinue it just to be safe. That was my last pill tonight so no problems there. Follow up Monday with primary doctor. Take Benadryl daily for I forget how many days. I’ve got that somewhere. In my purse probably- the Benadryl that is. My asthma was non existent since I’d just taken the albuterol inhaler 3 times in an hour for another flare up. So they weren’t sure what I reacted to but told me to stop the prednisone since it was the newest med. come to think of it one of the cat’s canned foods has seafood in it but I always wash my hands after feeding her wet food. I’ll have to watch which cans have it or not. Didn’t even think of that in the ER. Also N1 picked me up and took me home. I didn’t have to take an Uber.
