Infinity Pharma IP THYRO-3 25mcg (Cytomel T3)
Liothyronine Sodium 25 mcg Tablets USP — 25 mcg per Tablet
100 Tablets in white HDPE bottle with CRC in a box
I.P. THYRO-3 25 from Infinity Pharma is an oral thyroid hormone tablet formulated with Liothyronine Sodium (25 mcg per tablet), a synthetic form of the active thyroid hormone (T3). It is used in medical practice to replace or supplement thyroid hormone when the thyroid gland does not produce enough on its own. Liothyronine acts quickly after oral administration and is typically prescribed by a doctor based on individual thyroid hormone needs.

Benefits (According to Clinical Information & Websites)
✔️ Treats Hypothyroidism (Underactive Thyroid)
Liothyronine Sodium is indicated for thyroid hormone replacement therapy in conditions where the thyroid gland is not producing enough hormone, helping restore normal metabolic function and reduce symptoms of thyroid deficiency.
✔️ Improves Metabolism & Energy Levels
By supplying active thyroid hormone, THYRO-3 25 helps regulate metabolism, energy production, and body temperature, which can improve fatigue, cold intolerance, and sluggishness associated with low thyroid hormone levels.
✔️ Supports Thyroid Cancer Management (Adjunct Use)
Liothyronine may also be used as part of thyroid-stimulating hormone (TSH) suppression therapy in certain thyroid cancers after surgery or radioiodine therapy to reduce the stimulation of any residual cancer cells.
✔️ Fast-Acting Compared to T4 Hormones
Because it is the active T3 hormone, liothyronine is absorbed and becomes effective faster than some other thyroid replacement hormones, making it useful when a rapid hormone effect is desired.

Possible Side Effects
Like all thyroid hormone medications, Liothyronine Sodium tablets can cause side effects, particularly if the dose is too high or not properly monitored by a healthcare provider.
⚠️ Cardiovascular & Overdose-Related Effects
•Increased heart rate (palpitations), rapid or irregular heartbeat
•Chest pain or discomfort
•Increased blood pressure or altered heart rhythm
These effects are more likely if the dose is too high or if there are underlying heart conditions.
⚠️ Thyroid Excess (Hyperthyroid Symptoms)
•Nervousness, irritability, anxiety
•Excessive sweating and heat intolerance
•Weight loss or increased appetite
•Tremors and insomnia
These reflect symptoms of too much thyroid hormone in the body.
⚠️ Common Mild Reactions
•Headache
•Temporary hair loss (especially at the start of therapy)
These may occur as the body adjusts, but should be discussed with a doctor if persistent.
⚠️ Special Populations & Precautions
•Patients with heart disease or cardiovascular risk should be started on lower doses because thyroid hormone increases cardiac workload.
•This medication is not indicated for weight loss or fat-reducing purposes in people with normal thyroid function.
