Blue Triiodotyronine

COMMON BRAND NAME(S): Cytomel

CYTOMEL ORAL USES

Liothyronine is used to treat underactive thyroid (hypothyroidism). It replaces a hormone that is normally produced by the thyroid gland. Low thyroid levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. It is important to have adequate levels of thyroid hormone in your bloodstream to maintain normal mental and physical activity.

This medication is also used to lower thyroid function in certain diseases such as enlarged thyroid gland (goiter) and Hashimoto's thyroiditis. It is also used to test thyroid activity. Liothyronine is a man-made hormone that replaces the body's natural thyroid hormone (T3).

How to use Cytomel oral

Take this medication by mouth with or without food, usually once daily in the morning or as directed by your doctor.

Dosage is based on your medical condition, thyroid levels and response to therapy.

Take this medication 4 hours before or after taking any products containing aluminum or iron, such as antacids, sucralfate, and vitamins/minerals. Take liothyronine 4 hours before or after taking cholestyramine or colestipol. These products react with liothyronine, preventing its full absorption.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. Do not stop taking this medication without talking with your doctor. Thyroid replacement therapy is usually taken for life.

Symptoms of low thyroid levels include tiredness, muscle aches, constipation, dry skin, weight gain, slow heart rate, and sensitivity to cold. These symptoms should lessen as your body adjusts to the medication. It may take several days before you see an improvement in your condition. Inform your doctor if your condition does not improve or if it worsens after 2 to 3 days of treatment.
