Thyronorm 137 mcg Tablet

Thyronorm 137 mcg Tablet is a prescription thyroid hormone medicine containing 137 micrograms of levothyroxine (thyroxine) in each tablet. It belongs to the thyroid hormone replacement class and is used to treat hypothyroidism, a condition where the thyroid gland does not make enough hormone. Doctors also use it in some people after thyroid surgery, radioactive iodine treatment, or for certain goiter and thyroid-stimulating hormone suppression needs. Because it replaces a hormone the body normally makes, Thyronorm 137 mcg Tablet must be taken exactly as prescribed.

How it works: Levothyroxine in Thyronorm 137 mcg Tablet acts like the natural thyroid hormone T4 and is converted in the body to the active hormone T3. By replacing missing hormone, this tablet helps normalize metabolism, energy use, temperature control, heart rate, and many body functions.

Thyronorm 137 mcg Tablet is a relatively higher-strength tablet compared with the lower strengths such as 12.5 mcg, 25 mcg, 50 mcg, 62.5 mcg, 100 mcg, 112 mcg, and 125 mcg. It is usually chosen for people who have already been assessed by a doctor and need a dose adjustment that is between the 125 mcg and 150 mcg strengths. This strength is not meant for a new starter unless the prescriber specifically decides that 137 mcg is the right dose.

Each Thyronorm 137 mcg Tablet provides 137 micrograms of levothyroxine per tablet. Most people take it once daily, but the exact schedule and daily total depend on age, lab results, heart health, and the reason for treatment. Your doctor decides whether this 137 mcg strength is the right dose, and the maximum daily amount should not be increased on your own.

Do not change your dose or stop the medicine without speaking to your doctor.
