Xiao Ling is 35 years old, her daughter is 8 years old, and she wants to have another child. However, two years ago, she was found to be suffering from hypothyroidism during a medical checkup and has been taking Eugenol. Is it possible to get pregnant while taking the medication? Eugenol is a hormonal drug, should I still take it after I get pregnant? Should I stop taking it early? For many hypothyroid patients who want to get pregnant, it is inevitable that they will have similar doubts, and some of them even stop taking the medication on their own without consulting their doctors. Patients suffering from hypothyroidism have a thyroid gland that cannot synthesize and secrete the thyroid hormones they need, and need to rely on oral replacement therapy with adequate amounts of medication (commonly used as Eugenol or Raltez) in order to bring their bodies to a normal metabolic state. A woman’s thyroid hormone requirement usually increases by 30% to 50% during pregnancy to meet the needs of normal fetal development. If the amount of supplementation is insufficient, it will affect the development of the fetal brain and bones, and increase the risk of premature birth, miscarriage, low birth weight, stillbirth and gestational hypertension. Therefore, women with hypothyroidism who want to have a healthy baby should not only stop taking Eugenol, but also increase the dosage at the right time and in the right amount under the guidance of the doctor.
