Synthroid (Levothyroxine)

• Generic name: Levothyroxine
• Brand name: Levoxyl, Levothroid, Synthroid
• Drug class: Thyroid hormone

Synthroid (Levothyroxine T4) is a thyroid hormone. Thyroid hormones are produced and released by the thyroid gland and regulate the body's metabolism. When the thyroid gland is underactive (hypothyroidism) it does not produce enough hormone and metabolism slows.

Synthroid is used to treat hypothyroidism (low thyroid hormone). It is also used to treat or prevent goiter (enlarged thyroid gland). Having enough thyroid hormone is important for maintaining normal mental and physical activity.

Dosing issues: Variable effects of different brands

Levothyroxine is a prescription medicine with a narrow therapeutic index, so small changes in its bioavailability may lead to noticeably decreased or increased therapeutic effect. Different brands of levothyroxine are not interchangeable. This means a change in drug brand or formulation may require the dose adjustments and monitoring of thyroid hormone levels.

Contraindications

Levothyroxine is contraindicated in people with thyrotoxicosis (when thyroid gland is overactive and produces too much thyroxine), acute myocardial infarction, uncorrected adrenal insufficiency, or with hypersensitivity to any of the ingredients.

How to take

• Different brands of levothyroxine may not work the same. If you get a prescription refill for Synthroid or Levothyroxine and your new pills look different, talk with your pharmacist or doctor.
• It may take several weeks before your body starts to respond to this medication. Do not stop taking this medication suddenly. Even if you feel well, you may still need to take this medicine every day.
• It is very important to take levothyroxine with a full glass (8 ounces) of water. The levothyroxine tablet can dissolve very quickly and swell in the throat, possibly causing choking or gagging.
• Levothyroxine is usually taken in the morning, on an empty stomach, 30 minutes before eating. Calcium supplements and antacids can decrease the absorption of the drug.

Synthroid (Levothyroxine) dosage

Your doctor will adjust the dosage to meet your individual requirements, taking into consideration the status of your thyroid gland and other medical conditions you may have. Older adults often require somewhat smaller doses. To make sure Levothyroxine prescription dosage is right for you, the doctor will monitor your thyroid hormone level with periodic blood tests.

Don't Forget

Remember, when you buy a synthetic hormone Levothyroxine sodium without a prescription from your doctor, it is important to have a thyroid function testing at least annually.

Some of the potential serious problems that may occur from excessive or inadequate treatment with thyroid hormone medication include: recurrence of symptoms, osteoporosis, heart disease, preterm delivery in pregnancy, and hypercholesterolemia.
