I have irritant contact dermatitis on my face. The doctor prescribed 8mg methylprednisolone to be taken as 2 tablets for 5 days; 1.5 tablets for another 5 days; and 1 tablet for another 10 days. The drug store gave me 16mg methylprednisolone and the doctor said to adjust and take it. So, I plan to take in 1 tablet for 5 days and 1/2 a tablet for the remaining 15 days. Is it okay? Will that be a prolonged usage of the drug? Will the drug be flushed out of my system after the duration of usage? Please help!
