I have tonsillitis and the urgent care gave me 250mg Zpack & 50mg daily for 5 days of prednisone. I am a 36 yr old female who weighs 140 lbs. any time in the past that I happen to be put on prednisone was the dose never ever got over 20mg. I have not even had to take it in a long time. I'm sorry but 50mg is too high! I'm dizzy and overly tired. Red puffy rings where my eye lashes are. A lot of pressure in my head. My eyes are fluttering. I called to confirm my dose and they assured me it was correct. I explained my symptoms and they said it was still correct. Any advise???
