Enter your starting dosage and desired end dosage.
The calculator will produce a schedule of decreasing dosages for your taper at 10% decrease per step, calculated on the last dosage.
Each increment - 1, 2, 3 etc. - is a dose level, which should be held-at for a period, usually of 3 to 4 weeks.
For a rate of taper less than 10%, change Advanced Settings.
If measuring out to decimal places is not possible, round up on the dosage.
