Best Answer: Prednisone has a half-life of roughly 1 to 1.5 days. This means that after 4-6 days, levels of the drug drop below natural levels of cortisol, so it no longer has an effect. There's no way to predict the chances that your blood test results are caused by prednisone-you have to wait and see what happens.
I've been on it since the middle of August, 40mg a day..went into the hospital 2 weeks later and was up to 120mg a day..didnt show any puffiness in my face until i got out of the hospital, which was the end of september...so i've been on prednisone for about 3 months and im only on 15mg/day now..weaning off 5mg every week, so i'll be completely off ...
