The usual protocol for tapering off oral prednisone is 60 mg/d for 4 days, followed by a 10-day taper (50 mg/d for 2 days, 40 mg/d for 2 days, 30 mg/d for 2 days, 20 mg/d for 2 days, then 10 mg/d for 2 days).
So you need to follow this protocol.
You should take 10 mg/d for 2 days before stopping the medication.
You should take your missed dose now if it is not more than 4 hours and take your next dose as per schedule.
It is not advisable to take oneself off of it suddenly.
Because of severe unwanted effects on body as adrenal glands steroid production is supressed and if external intake is stopped suddeny, it leads to steroid deficiency in body with severe consequencial effects.
Skip the missed dose if it is almost time for your next scheduled dose.
Do not take extra medicine to make up the missed dose.
And consult your doctor as well if your rash has gone completely.
Hope this helps.
