Which class of medication is primarily used for menstrual cycle regulation?

Oral contraceptives are the class of medication primarily used for menstrual cycle regulation because they contain hormones that help to control the menstrual cycle. They can regulate the timing of periods, mitigate heavy bleeding, and alleviate symptoms associated with premenstrual syndrome (PMS).

The hormones in oral contraceptives—typically a combination of estrogen and progestin—work by suppressing ovulation, stabilizing the endometrial lining of the uterus, and providing hormonal balance, which collectively contributes to regularizing menstrual cycles. As a result, healthcare providers often prescribe them for those experiencing irregular menstrual cycles or other related issues.

Other medication classes listed do not serve the purpose of regulation of menstrual cycles. Antidepressants may address mood disorders but do not have a primary role in menstrual regulation. Antipsychotics are used primarily to treat severe mental health conditions, and mood stabilizers are typically prescribed for mood disorders such as bipolar disorder. While these medications may have side effects that can impact menstrual cycles, they are not directly used for this purpose.
