Why Was I Prescribed Methylprednisolone For My Wheezing Cough, And Will Irregular Dosing Affect Its Effectiveness?

hi,why the doctor advised to take 16mg Methylprednisolone for 2 times a day for 3 days and once a day for 4 days for my wheezing cough. what if i will take on the 1st day in 2 x a day as dr adviced then on 2nd day once a day only?
