Introduction

Under normal circumstances, taking Euthyrox (levothyroxine) during pregnancy does not negatively affect the fetus. Euthyrox is identical to the thyroid hormone secreted by the human thyroid gland, and thyroid hormones play a significant role in the development of the fetal brain and nervous system. Therefore, for pregnant women with hypothyroidism, taking this medication can supplement the deficient thyroid hormones and help maintain normal thyroid function.

Generally speaking, Euthyrox refers to levothyroxine sodium. Pregnant women taking levothyroxine sodium will not affect the fetus. The detailed explanation is as follows:

Levothyroxine sodium is identical to the thyroxine secreted by the human thyroid gland. Thyroid hormones play a significant role in the development of the fetal brain and nervous system. Therefore, for pregnant women with hypothyroidism, taking this medication can supplement the deficient thyroid hormones and maintain normal thyroid function in the body.

It should be noted that pregnant women must take this medication in appropriate doses under a doctor's guidance to avoid adverse effects on the fetus due to excessive dosage. If a pregnant woman has thyroid-related diseases, she should regularly monitor her thyroid function so the medication dosage can be adjusted accordingly, preventing hyperthyroidism caused by excessive intake, which could negatively affect both the mother and the fetus.

During treatment with levothyroxine sodium, pregnant women should pay attention to any adverse reactions such as gastrointestinal symptoms including nausea, vomiting, and diarrhea. If adverse reactions occur, prompt medical attention is recommended. Sufficient rest and maintaining healthy lifestyle habits are also important for recovery.
