What is Levothyroxine?

Levothyroxine is a medicine that helps people who have an underactive thyroid. The thyroid is a small gland in the neck that makes hormones to control energy and metabolism. When the thyroid does not make enough hormones, a person can feel tired, gain weight, or feel cold all the time. This condition is called hypothyroidism.

Levothyroxine is a replacement hormone that helps bring hormone levels back to normal. It is one of the most common medicines used for thyroid problems.

How to Take Levothyroxine

Doctors usually prescribe levothyroxine as a small pill that is taken once a day. It is best to take it in the morning, at least 30 to 60 minutes before eating, with a full glass of water. Food, coffee, and other medicines can affect how well the body absorbs levothyroxine, so it’s important to follow the doctor’s instructions carefully.

Common Side Effects

Most people take levothyroxine without problems, but some may experience side effects, especially if the dose is too high. Common side effects include:

• Fast heartbeat
• Nervousness or anxiety
• Trouble sleeping
• Sweating more than usual
• Weight loss

If a person feels these symptoms, they should talk to their doctor. The doctor may adjust the dose to make sure the medicine is working correctly.

How Long Does Levothyroxine Take to Work?

Levothyroxine does not work right away. It can take a few weeks before a person starts to feel better. Doctors often check blood tests to make sure the dose is correct. If necessary, they will adjust the medication to help the patient feel their best.

Important Things to Know

• Do not stop taking levothyroxine suddenly without talking to a doctor. The body needs the hormone to work properly.
• Be consistent—take it at the same time every day.
• Tell your doctor if you take vitamins or other medicines, as some can interfere with levothyroxine.

Conclusion

Levothyroxine is an important medicine for people with an underactive thyroid. It helps them have more energy, maintain a healthy weight, and feel better overall. By taking it the right way and working with a doctor, people with hypothyroidism can live a normal and healthy life.
