The progestogen-only pill (POP) is a highly effective contraceptive, with a Pearl Index of 0.2. While menstrual irregularity was a common reason for discontinuation, many users maintained regular cycles, suggesting POPs are acceptable for long-term use.

Area of Science:

  • Family Planning
  • Reproductive Health
  • Contraception

Background:

  • Progestogen-only pills (POPs) are a type of oral contraceptive.
  • Assessing the long-term efficacy and acceptability of POPs is crucial for family planning services.

Purpose of the Study:

  • To evaluate the effectiveness and side effects of the progestogen-only pill (POP) in a family planning clinic setting.
  • To analyze reasons for discontinuation and menstrual pattern changes among POP users.

Main Methods:

  • Retrospective analysis of 358 women using POPs over 18,125 women-months.
  • Calculation of the Pearl Index to determine pregnancy rates.
  • Documentation of side effects and reasons for discontinuation.

  • Three pregnancies occurred, resulting in a Pearl Index of 0.2 per 100 women-years.
  • Minor non-menstrual side effects were reported by 77 women.
  • Menstrual irregularity was the primary reason for discontinuation (47.5%), yet 40% of users maintained regular cycles.

Conclusions:

  • The progestogen-only pill (POP) demonstrates high contraceptive efficacy and is acceptable for long-term use.
  • Active promotion of POPs is recommended as a viable oral contraception option.
