Extended-cycle oral contraception: a new option for routine use

Area of Science:

• Gynecology
• Reproductive Endocrinology

Background:

• Oral contraceptive (OC) pills are widely used for pregnancy prevention and managing gynecological conditions.
• Traditional OC use involves a 21-day active pill cycle followed by a 7-day hormone-free interval, resulting in withdrawal bleeding.
• Withdrawal bleeding, an iatrogenic event, is often perceived as a necessary indicator of OC efficacy but can cause discomfort and incur costs.

Purpose of the Study:

• To evaluate the efficacy and safety of extended-cycle oral contraceptive (OC) use in suppressing menstruation.
• To assess patient and healthcare provider acceptance of OC regimens that reduce or eliminate withdrawal bleeding.
• To inform clinical practice regarding personalized OC use based on patient preference.

Main Methods:

• Review of clinical trials and accumulated experience with extended-cycle OC use.
• Analysis of bleeding patterns, including unscheduled bleeding and spotting, in women using extended-cycle regimens.
• Consideration of patient-reported outcomes related to comfort and cost.

Main Results:

• Extended OC use successfully suppresses endometrial activity and prevents menstruation for several months.
• Initial clinical trials show a temporary increase in unscheduled bleeding and spotting with extended-cycle OC use.
• Over time, unscheduled bleeding and spotting decrease to levels comparable to conventional-cycle regimens, with an overall reduction in total bleeding days.

Conclusions:

• Extended oral contraceptive (OC) use is a safe and effective strategy to eliminate or reduce monthly withdrawal bleeding.
• Eliminating unnecessary withdrawal bleeding can improve patient comfort, reduce out-of-pocket expenses, and enhance adherence.
• Women should have the autonomy to choose their preferred OC regimen, including the option for extended use without periodic withdrawal bleeding.
