Synthroid is prescribed to those with hypothyroidism, who have low levels of thyroid hormones and may benefit from a synthetic hormone. Whether you need an initial diagnosis or prescription refill, we can help you. 

What is Synthroid?

Synthroid is one of the most common synthetic hormones (generic name, levothyroxine) prescribed to individuals with insufficient levels of thyroid hormones.

Synthetic hormones, such as Synthroid, are crucial to help your body convert food into energy, among other important processes.

Hypothyroidism Risk Factors

While anybody can get hypothyroidism, you have a higher risk if you:

Have a family history of thyroid problems

Are a woman

Have an autoimmune disease, such as type 1 diabetes or celiac disease

Have recently had thyroid surgery

Received radiation to your neck or upper chest

Are older than 60

Precautions and side effects of Synthroid

Before taking any new medication be sure to talk with your doctor about the potential risks and side effects.

You should always tell your doctor your complete medical history and all medications you are taking, including supplements and recreational drugs to ensure there are no harmful drug interactions.

While Synthroid is generally considered safe, it isn’t for everybody. It can lead to osteoporosis, especially in women.

Synthroid is not approved for weight loss in people with normal thyroid function and should only be taken by people who are deficient in thyroid hormone.

Synthroid can cause life-threatening complications in people with normal thyroid levels.
