Yes, prednisolone orally is to be taken in the morning. This is because there is a diurnal variation in the amounts of endogenous steroids produced - the greater in the morning. It is also hoped that this will help the transition from oral to endogenous state.
Pred very often disturbs sleep.
Pred can cause quite bad upper digestive upset, some doctors concomitantly give anti-acid pills. Taking with, or at end of food can help.
Of course - Your Mileage May Vary!
