Pharmacology · Endocrine drugs: progestin-only pill in lactation
Sample itemA woman 8 weeks after delivery is exclusively breastfeeding and wants a daily oral contraceptive. Which type is preferred?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. A progestin-only pill
Oestrogen can reduce milk volume and adds thrombotic risk in the early postpartum period, so progestin-only pills are preferred for breastfeeding women. They do not affect lactation.
Option by option
A. A combined oestrogen-progestin pill
Combined pills can reduce milk production and carry a postpartum thrombotic risk.
B. A high-dose oestrogen pill
High-dose oestrogen was used to suppress lactation and would do so here.
C. A pill containing an anti-androgen
An anti-androgen pill is used for hirsutism and acne and is not a contraceptive choice in lactation.
D. A progestin-only pill (correct)
Correct. Progestin-only pills do not reduce milk supply and avoid oestrogen risks.
