Correct answer: D — Advise prompt GP or antenatal review because levothyroxine requirements often increase in pregnancy
Pregnancy increases thyroxine requirements in many patients and maternal hypothyroidism can affect pregnancy outcomes. Prompt review and thyroid function monitoring are needed. Levothyroxine should not be stopped. Iron-containing supplements can reduce absorption if taken at the same time, so spacing advice is also relevant.
