Levothyroxine is a medication used to treat underactive thyroid, also called hypothyroidism. Brand name equivalents of Levothyroxine include Synthroid, Levo-T and Euthyrox.
Levothyroxine is a lab-made chemical that imitates the hormone that a normal thyroid produces. This helps your body have enough of the hormone to carry out its normal functions.
Levothyroxine doses are taken once daily, can be variable and often change depending on your body’s needs. Levothyroxine is usually well tolerated but may cause some stomach upset when you’re first starting to use the drug.

In the deductible stage, you’re responsible for the full cost of your prescription drugs.
Some Medicare prescription drug plans have a $0 deductible. Medicare drug plans cannot have a deductible more than $415 in 2019.
|After you meet your Part D deductible, you enter the initial coverage period.
During this phase (the typical copay stage), you pay a copayment (flat fee) or coinsurance (percentage) for your covered medications.

Since your thyroid is very sensitive, it may take time to find the right dose of levothyroxine for your body.
Signs of an underactive thyroid can include slowed heartbeat, constipation, intolerance to cold, depression, fatigue, forgetfulness and weight gain, among other symptoms.
Signs of an overactive thyroid or too much levothyroxine include rapid heartbeat, weight loss, frequent bowel movements, difficulty sleeping, heat intolerance and nervousness. If you experience symptoms of too little or too much levothyroxine, call your doctor to let them know.
For the most benefit, you should take levothyroxine on an empty stomach 30-60 minutes before breakfast. Avoid antacids with aluminum, magnesium or calcium carbonate within 4 hours before or 4 hours after taking levothyroxine.
You should not use levothyroxine if you have any type of thyroid nodules. Some exceptions can be made, but use caution.
Levothyroxine should also be used with caution in postmenopausal women, elderly patients and patients with heart disease and osteoporosis. Caution should also be used in patients with diabetes.
