Pregnant women's thyroid-stimulating hormone (TSH) levels may continue to rise despite taking Levothyroxine (Euthyrox).

During pregnancy, if a pregnant woman's thyroid-stimulating hormone (TSH) level is found to be elevated, it usually indicates the presence of hypothyroidism. To address this issue, doctors may prescribe Euthyrox (levothyroxine sodium tablets) for treatment. Some pregnant women may worry that their TSH levels might increase rather than decrease after taking levothyroxine sodium tablets. In fact, such a situation is relatively rare, but it can indeed occur due to various reasons, such as an insufficient medication dosage, individual differences, or dietary influences. Therefore, during the course of taking levothyroxine sodium tablets, pregnant women should strictly follow medical instructions for medication use and regularly retest their thyroid function, allowing doctors to adjust the medication dosage according to the test results. Additionally, pregnant women should maintain healthy lifestyle habits, such as keeping a positive mood, engaging in moderate outdoor physical activity, and maintaining a healthy diet, to support treatment and enhance immune function. If any discomfort or questions arise, they should promptly consult a doctor to receive timely and effective care.
