Levothyroxine is a synthetic version of the hormone thyroxine, which is produced by the thyroid gland. It is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone, and to help decrease the size of enlarged thyroid glands. Levothyroxine is also used in combination with surgery and radioiodine treatment for thyroid cancer. While it is generally safe to take levothyroxine for long periods, it can cause side effects such as muscle spasms, joint pain, and muscle weakness.

What You'll Learn
Levothyroxine treats hypothyroidism
Levothyroxine is a synthetic version of the hormone called thyroxine. It is a prescription drug used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. This medication replaces the thyroxine that the thyroid gland cannot produce, thereby preventing the symptoms of hypothyroidism.
When the thyroid gland does not make enough thyroxine, many of the body's functions slow down. Common symptoms of an underactive thyroid include poor growth, slow speech, lack of energy, excessive tiredness, constipation, weight gain, hair loss, dry and thick skin, increased sensitivity to cold, joint and muscle pain, heavy or irregular menstrual periods, and depression. Levothyroxine works to reverse these symptoms.
Levothyroxine starts working immediately, but it may take several weeks before symptoms start to improve. Treatment with this medication is usually lifelong, as stopping the medication will likely cause symptoms to return. It is generally safe to take levothyroxine for a long time, even for many years. However, high doses over an extended period can cause weakening of the bones, a condition known as osteoporosis.
Like all medications, levothyroxine can cause side effects, although not everyone experiences them. The most common side effects are caused by taking a higher dose than needed, and they usually go away after lowering the dose or stopping the treatment. Common side effects include tremors, insomnia, heart-related problems, headaches, and muscle spasms or weakness.

Levothyroxine may interact with other medicines
Levothyroxine is a synthetic version of the hormone thyroxine, which is typically produced by the thyroid gland. When the thyroid gland does not produce enough thyroxine, levothyroxine is administered to prevent the symptoms of hypothyroidism. Levothyroxine is usually taken once a day on an empty stomach, 30 minutes to 1 hour before breakfast.
Levothyroxine is known to interact with many other medications, and these interactions can prevent the medication from working as intended. It is imperative to inform your doctor or pharmacist about all the medications you are taking, including prescription and nonprescription drugs, as well as any supplements. This will enable your healthcare provider to evaluate all possible interactions and devise a plan to avoid or minimise them.
Some of the medications that are known to interact with levothyroxine include proton pump inhibitors such as esomeprazole (Nexium), lansoprazole (Prevacid), and omeprazole (Prilosec); antacids; bile acid sequestrants; simethicone; salicylate pain relievers such as aspirin and aspirin-containing products; choline magnesium trisalicylate; choline salicylate (Arthropan); diflunisal (Dolobid); magnesium salicylate (Doan's); salsalate (Argesic, Disalcid, Salgesic); niacin; nonsteroidal anti-inflammatory medications (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn); and prednisone.
Additionally, certain foods and beverages can also affect how levothyroxine works. It is recommended to avoid consuming coffee, milk, soy products, walnuts, and dietary fibre within an hour of taking levothyroxine, as they can reduce the absorption of the medication. Calcium, iron, and magnesium supplements can also lower levothyroxine levels, so it is advised to separate the administration of these supplements from levothyroxine by 4 hours.
