Liothyronine

Liothyronine is a medicine used to treat an underactive thyroid gland (hypothyroidism). It replaces the hormone which is not being produced by your thyroid gland in sufficient quantity and helps regulate your body’s energy and metabolism.

Before you start taking Liothyronine, your doctor will do a blood test to see what dose you need. Once you start taking the medicine, you will have regular blood tests to see how well it is working, and the dose may be adjusted from time to time. It is best taken on an empty stomach before your first meal of the day. You should take this medicine regularly to get the maximum benefit. It may take several weeks before your symptoms start to improve. You may need to take it for the rest of your life. If you stop taking it, your symptoms are likely to come back.

The most common side effects of this medicine are caused by taking a higher dose than you need. Possible side effects include arrhythmias, myocardial infarction, dyspnea, headache, and nervousness among others. Most side effects will disappear once you are on the right dose. Call your doctor straight away if you have a very high temperature, fast or irregular heart rate, low blood pressure, yellowness in the eye/skin, confusion, or fits.

Liothyronine may cause weight loss but should not be prescribed or taken to treat obesity. If you become pregnant while taking this medicine, inform your doctor right away as the dose may have to be increased/readjusted. Many other drugs affect the way this medicine works. Ask your doctor for advice if you are taking any other medications.

Treatment of Hypothyroidism
Liothyronine is a synthetic version of thyroid hormone that is naturally produced in your body. When your body does not produce enough thyroxine, you get hypothyroidism. Some symptoms of hypothyroidism include tiredness, weight gain, and muscle aches. This medicine raises your hormone level to the right amount and helps you get rid of these symptoms. For most people, this is a lifelong medication and should not be discontinued without talking to your doctor.

It may take a while for this medicine to work properly. Your doctor may get regular blood tests done to determine the effectiveness of this medicine and to make sure that you are on the right dose.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
