Synthroid (Levothyroxine) Online FAQs

Man holding up a bottle of medication and smiling

What is Synthroid (Levothyroxine)?

Levothyroxine is a type of hormone replacement medication for thyroxine (T4). The thyroid makes thyroxine, but sometimes it cannot make enough to keep levels adequate. Levothyroxine treatment helps regulate energy and metabolism functions in the body in those who do not make enough of it on their own.

Levothyroxine is available as a generic or under the brand name Synthroid. It comes in capsules in a wide range of doses. Healthcare professionals use lab testing to check on thyroid function and determine the correct treatment and medication dose. Common blood tests used to check on thyroid function and monitor response to treatment include TSH and T4 levels. In some cases, more specialized labs are needed. 

For thyroid hormone replacement to work, it must be taken consistently every day as directed. Levothyroxine needs to be taken on an empty stomach. Many healthcare providers suggest taking it first thing in the morning, although evidence shows that it can be just as effective when taken on an empty stomach right before bed.

How does Synthroid (Levothyroxine) work?

Levothyroxine is a synthetic version of a hormone the body naturally makes called thyroxine (T4). Thyroid hormone regulation is a complicated process relying on different parts of the brain and endocrine (hormone) system. When the body can’t make enough T4 on its own (which can happen for many reasons), taking levothyroxine can have the same effect within the cells to increase metabolism and support normal energy production.

Can I get Synthroid (Levothyroxine) online?

Generic levothyroxine and Synthroid are not available over the counter. Both require a doctor’s prescription. With that, you can get levothyroxine from most pharmacies, including online pharmacies. 

How much does Synthroid (Levothyroxine) cost?

Pricing of Synthroid (Levothyroxine) varies depending on your insurance, dosage, the specific pharmacy, and if you take the generic or name brand medication.

Without insurance, Synthroid can average about $65 per month. Generic levothyroxine is less expensive, costing around $16 per month. 

Insurance coverage varies, and copays may range from a few dollars to the full price.

For patients who qualify, some manufacturers offer assistance programs. Anyone can also use prescription savings programs online or at pharmacies to reduce costs.

What does Synthroid (Levothyroxine) treat?

Levothyroxine is used to treat thyroid-related hormone problems, including:

  • Hypothyroidism
  • Pituitary gland disorders that affect TSH (secondary hypothyroidism)
  • Goiters (enlargement of the thyroid gland)

Levothyroxine may also be used in some patients who have specific types of thyroid cancer and require surgery or radioiodine therapy.

Is Synthroid (Levothyroxine) available over the counter?

No, Synthroid (Levothyroxine) is only available with a prescription from a medical provider.

What are the side effects?

Levothyroxine may cause some common side effects. In most cases, these will resolve once your body adjusts to the medicine. However, sometimes side effects occur because the dosage needs to be adjusted. So if you experience side effects from levothyroxine, talk to your healthcare provider.

Common side effects include:

  • Shakiness
  • Fast heart beat
  • Hair loss
  • Sweating
  • Weight loss
  • Insomnia or problems sleeping
  • Fatigue
  • Muscle weakness
  • Anxiety

Precautions and risks of Synthroid (Levothyroxine)

Levothyroxine is not indicated for everyone. You should not take it if you are allergic to any of the ingredients. Also tell your healthcare provider and pharmacist if any of the following is true for you:

  • Pregnant or breastfeeding
  • Kidney disease
  • Liver disease
  • Heart disease
  • Blood vessel disease
  • Anemia (low iron)
  • Blood clotting disorders
  • Diabetes
  • Osteoporosis
  • Adrenal gland disorders
  • Pituitary gland problems
  • Recent radiation iodine treatment

Tell your medical provider and pharmacist about all medications, over-the-counter drugs, and herbal or dietary supplements that you take. Many of them can interact with levothyroxine.

Do not consume grapefruit juice or grapefruit while taking levothyroxine.

In rare cases, levothyroxine may cause serious problems, including angina (chest pain), heart rhythm problems, and low bone density.

While levothyroxine may lead to weight loss in people who have an underactive thyroid, it is not a weight-loss drug and should not be taken for this purpose.

Do not suddenly stop taking levothyroxine. If appropriate, your doctor will help you slowly wean you off of the medication.

Keep all medical appointments and follow through with lab testing that your medical provider orders. Blood tests are necessary to understand whether your thyroid hormone levels are well managed.
