Synthroid and Pregnancy

Synthroid is considered a pregnancy Category A medication, meaning that it does not appear to cause harm to the fetus. In fact, very few medications have been given this classification -- it is an excellent indication that Synthroid and pregnancy is a safe combination. Because your Synthroid dosage may need to be increased during pregnancy, your healthcare provider should monitor you closely and adjust your dosage as necessary.

Synthroid and Pregnancy: An Overview

Synthroid® (levothyroxine sodium) is a prescription medication used to treat hypothyroidism (an underactive thyroid) and various other thyroid problems. The medication is safe for use during pregnancy.
 

Synthroid and Pregnancy Category A

The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category A is given to medicines that have been extensively studied in pregnant humans and that do not appear to cause any harm to the fetus. Very few medications have been given this classification; it is an excellent indication that a medication is safe for use during pregnancy.
 
Because hypothyroidism can cause serious problems (such as miscarriages), it is important to treat an underactive thyroid during pregnancy. If you are already taking Synthroid, it is likely that your dose may need to be increased throughout your pregnancy. In fact, your dose may need to be increased as early as four weeks into your pregnancy. Your healthcare provider should monitor you closely and adjust your Synthroid dosage as necessary.
 

Synthroid and Pregnancy: Final Thoughts

If you are pregnant or are thinking about becoming pregnant, let your healthcare provider know. He or she will need to monitor you more closely, as pregnant women often need higher doses of Synthroid. You can be assured that this medication is safe for use during pregnancy.
