Had An Allergy, Constipated. Prednisone And Steroids. Can I Change The Dosage?

Hello Dr. Grief, i just want ask about the effect of prednisone. Last week i had a minor operation, in my anus.my doctor prescribed me colace to prevent constipation. After 24 hours I had an allergy to my medicine that i took. So my husband brought me back to the hospital due to my severe allergy. My doctor prescribed me 8 tablets of 5 mg prednisone single dose for 3 days. These morning i went to his clinic for follow up , and I ask if i will continue my prednisone. He said stop taking my steroid. My question now , since the doctor did not tapered the dosage and he stopped just like that, is there any effect to my body since this is my first time to having this kind of medicine. Hoping that this question will help to my worries. I know that prednisone should be taking continuesly by tapering the dosage before it will stop. Thank you doctor for taking your time to answer my question.
