Contraception and Family Planning — MCQs

Q: What is the dose of mifepristone in medical abortion?

200 mg. ***200 mg*** - The standard dose of **mifepristone** for **medical abortion** in various protocols, including those up to 10 weeks of gestation, is **200 mg orally**. - This dose effectively blocks **progesterone receptors**, leading to endometrial breakdown and sensitization of the uterus to prostaglandins. - **WHO-recommended dose** with optimal efficacy and safety profile. *400 mg* - **400 mg is not a standard or recommended dose** for medical abortion in any established protocol. - The evidence-based regimens use either **200 mg** (current standard) or 600 mg (older protocol), but not 400 mg. - No clinical advantage has been demonstrated for this intermediate dose. *100 mg* - A dose of **100 mg of mifepristone is considered suboptimal** and less effective for inducing medical abortion compared to the standard 200 mg dose. - It may not sufficiently block progesterone receptors, potentially leading to **incomplete abortion** or treatment failure. - Not recommended in any standard medical abortion protocol. *600 mg* - Although **600 mg was an older protocol** for medical abortion, it has largely been replaced by the **200 mg dose**. - Research has demonstrated that **200 mg is equally effective** while resulting in a better side effect profile and lower cost. - The dose reduction from 600 mg to 200 mg represents evidence-based protocol optimization.
