A patch may have a longer duration of action than an oral medication. Some medications such as estrogen or clonidine patches, can be worn for several days. A Daytrana patch is not supposed to be used for longer than 9 hours. The effect starts about 2 hours after the patch is applied and continues for about 3 hours after the patch is removed. If one wears the patch for 9 hours one gets about 10 hours of significant drug effect. A patch can promote greater flexibility of dose duration.
