For medical abortion up to 12 weeks' gestation, the recommended drug dosages are 200 milligrams of mifepristone by mouth, followed one to two days later by 800 micrograms of misoprostol inside the cheek, vaginally, or under the tongue. [18] The success rate of this drug combination is 96.6% through 10 weeks' pregnancy. [19]
Routes can also be classified based on where the target of action is. Action may be topical (local), enteral (system-wide effect, but delivered through the gastrointestinal tract), or parenteral (systemic action, but is delivered by routes other than the GI tract).

[242] [265] Irritation of the intestines does not usually occur with rectal estradiol. [261]
