Whether a pregnancy can continue after taking medication for hyperthyroidism requires consideration of the type of medication, the dose taken, and the control of the condition. If the dose of medication taken is small and the condition is well controlled, the pregnancy can usually continue. When a woman becomes pregnant unexpectedly while taking anti-hyperthyroid medication, the medication may affect the fetus, and she should consider whether to terminate the pregnancy. In general, before deciding to terminate the pregnancy, women should ask their doctor to give them reasonable advice based on their medication status, such as the type of anti-hyperthyroid medication they are taking and the dosage they are taking. If the dose of medication taken is small and the condition is well controlled, the pregnancy can usually continue. Therefore, if you are pregnant after taking the medication for hyperthyroidism, whether you can have this fetus or not, it is recommended that you go to a regular hospital to have a detailed examination and have a professional doctor give you a reasonable advice before you make a decision.
