Common use

Liothyronine is a synthetic form of the thyroid hormone triiodothyronine (T3), used to treat hypothyroidism and related thyroid disorders. It helps restore normal energy levels, metabolism, and mental function in individuals with low thyroid hormone levels. It is also used in certain cases of thyroid cancer and for diagnostic testing of thyroid function. Liothyronine acts more quickly than levothyroxine (T4), making it useful in specific clinical situations.

Dosage and direction

The dosage of liothyronine is individualized based on:

• Patient's age
• Weight
• Medical condition
• Response to therapy

It is usually taken orally once daily, preferably at the same time each day, with or without food. Dose adjustments should be made gradually to minimize side effects. Regular blood tests are needed to monitor thyroid hormone levels and ensure proper dosage.

Precautions

Before using liothyronine, inform your doctor if you have:

• History of heart disease
• Adrenal insufficiency
• Diabetes

This medication can increase heart rate and metabolism, which may be risky for individuals with cardiovascular conditions. It is not meant for weight loss and should not be used for obesity treatment. Always follow your doctor's instructions closely.

Contraindications

Liothyronine is contraindicated in patients with:

• Uncorrected adrenal insufficiency
• Untreated thyrotoxicosis
• Known hypersensitivity to the drug

It should not be used as a weight-loss agent due to the risk of serious effects. Patients with recent heart attacks should use it only under strict medical supervision. Use during pregnancy should be carefully monitored but is generally considered safe when necessary.
