I am 18 years old and have been put on prednisone three times in the past three months and I also received a shot of it when I had an allergic reaction back in August. The doctor keeps prescribing prednisone for infected tonsils however it seems my side effects get worse every time. I tapered off my last dose last sunday however I am still experiencing headaches, strange thoughts, mood swings, and slight depression. I have asked the doctor and he said its normal however I am starting to worry.
