Levothroid Medication Information

Available by prescription only, Levothroid® (levothyroxine sodium) is a medication that may be recommended if your thyroid levels are low. Although it is most often used to treat an underactive thyroid (hypothyroidism), it is also approved to treat a few other thyroid problems as well, such as thyroid cancer, goiters, or nodules. One tablet is typically taken each morning. Most people tolerate it well, but side effects may include things like hair loss, rapid heart rate, and heart palpitations.
To help ensure your safety with Levothroid, make sure your healthcare provider has up-to-date information on any other medications you are taking, including nonprescription products, as well as any allergies you may have, including to any drugs, foods, dyes, or preservatives. Also, let your healthcare provider know if you are pregnant or breastfeeding.
