Did the word “hypothyroidism” just become a part of your vocabulary after your last doctor visit? Your doctor may have told you your TSH levels may be high. In simple terms, your body isn’t producing enough thyroid hormone.

Synthroid is a medication that does just what it sounds like. It is a synthetic version of the hormone typically produced by a person's thyroid.

What does Synthroid treat?

Synthroid is used to treat Hypothyroidism, also called under active thyroid disease; a condition where the thyroid doesn't produce enough thyroid hormone. Your body uses thyroid hormone to regulate metabolism, which affects body temperature, how quickly your body digests food, and heartbeat. Without enough thyroid hormone the body's processes slow down. Common symptoms from hypothyroidism include feeling cold, unexplained weight gain or difficulty losing weight, hair loss, depression, lack of energy, swelling of the thyroid gland (also known as 'goiter', but let's stick with 'swelling').

Who can take Synthroid?

Almost anyone who needs it can take Synthroid, but if you have heart problems, diabetes, osteoporosis, or any other medical condition make sure you discuss it with your doctor before going on the medication. There is no cure for hypothyroidism, so you usually will take it for life.

Synthroid is a class A medication, which means that thankfully it is safe for pregnant women; pregnancy has enough side effects on its own without the symptoms of hypothyroidism added to the mix ( Pregnant women may need a higher dose during pregnancy than they did before it. Some Synthroid may pass into the breast milk of a nursing woman, but it shouldn't negatively affect the baby.

Side effects of Synthroid

The most common side effect of Synthroid is some hair loss as your body adjusts to the medication. This usually resolves itself within a few months, quickly enough that you shouldn't go bald. Other side effects include diarrhea, sensitivity to heat, mood swings, and headaches; so really the opposite of having low thyroid symptoms. These symptoms can usually be resolved by changing the dosage until it is just right. If the extremely rare side effects of seizures, chest pain, and irregular heartbeat occur, go straight to the ER.

Benefits of Synthroid

If you've got hypothyroidism that hasn't been treated, chances are good that you haven't been feeling all that great. It is no fun to feel cold all the time and exhausted. It is frustrating to feel defeated when trying to eat right and exercise, and still gain weight or be unable to lose weight. Those who go on Synthroid usually start feeling better within a few months. They have more energy, and many people lose weight on it because their metabolism is back to normal. The fog of depression starts to lift, and they start to feel happier and more interested in things that used to interest them. It may even help regulate a woman's menstrual cycle and improve her fertility.


Synthroid is a pill that is taken daily. Dosage is based on a variety of factors and it is not uncommon for your doctor to have to try a few different dosages before settling on the one that is right for you. If babies or toddler need Synthroid there is a liquid form for them.
