When initiating progestin-only contraceptives, women should be advised to use a backup method for how long?

• A. 1 week
• B. 1 month
• C. 3 weeks
• D. 6 weeks

Answer: (B)

When initiating progestin-only contraceptives, it is recommended that women use a backup method of contraception for one month. This guidance is important because it allows sufficient time for the progestin-only method, often referred to as the "mini-pill," to achieve effectiveness and prevent unintended pregnancy. Progestin-only contraceptives work primarily by thickening cervical mucus to block sperm, inhibiting ovulation, or altering the endometrial lining. However, it may take some time (up to 7 days) for the body to adjust to the hormonal changes and for the contraceptive method to become fully effective if it is not started at the beginning of the menstrual cycle. Using a backup method, such as condoms, during this initial month ensures that the woman is protected from pregnancy while her body is becoming accustomed to the new contraceptive method. This practice is particularly vital because the immediate effectiveness of progestin-only pills is not guaranteed if they are started at a time that does not align with a woman's menstrual cycle. The recommendation for a one-month backup aligns with standard guidelines in contraceptive management, emphasizing the importance of ensuring full contraceptive efficacy before relying solely on the new method.
