Tirosint is a brand-name prescription medication containing Levothyroxine Sodium in a unique gel capsule formulation. It is manufactured by IBSA Pharma and is used as thyroid hormone replacement therapy for patients with hypothyroidism (underactive thyroid). It is also used as an adjunct to surgery and radioiodine therapy for the management of certain thyroid cancers.
What sets Tirosint apart from standard Levothyroxine tablets is its minimal inactive ingredients — containing only gelatin, glycerin, and water. This makes it an excellent option for patients with absorption issues, food sensitivities, or allergies to dyes and fillers found in conventional tablets.

Tirosint contains synthetic Levothyroxine (T4), which is chemically identical to the thyroxine naturally produced by the thyroid gland. Once absorbed, T4 is converted to the active hormone triiodothyronine (T3) in peripheral tissues. Thyroid hormones regulate metabolism, protein synthesis, growth, and development by binding to nuclear thyroid hormone receptors and influencing gene expression.
Tirosint's gel capsule formulation may offer more consistent absorption compared to tablets, particularly for patients who take other medications or have gastrointestinal conditions that affect absorption. It should be taken on an empty stomach, 30–60 minutes before breakfast.

Tirosint scores a 62 out of 100 on our findability scale, meaning it can be intermittently difficult to locate. As a brand-name, niche formulation of Levothyroxine in gel capsule form, Tirosint is not stocked as widely as standard Levothyroxine tablets. While it is not currently listed on the FDA drug shortage database, its specialty status means not every pharmacy carries it. Patients may need to call multiple pharmacies or use tools like Medfinder to locate it in stock nearby.
Broader Levothyroxine supply disruptions in 2024–2025 have also increased demand for alternative formulations like Tirosint, which can further strain availability at certain locations.

Serious side effects that require immediate medical attention include rapid or irregular heartbeat, chest pain, shortness of breath, seizures, and signs of hyperthyroidism (excessive sweating, tremors, nervousness, insomnia, fever).

Tirosint is a premium Levothyroxine formulation that offers distinct advantages for patients with absorption concerns, sensitivity to inactive ingredients, or inconsistent results with standard tablets. While its higher cost and niche market status can make it harder to find and more expensive than generic alternatives, programs like the Tirosint Copay Savings Card ($25/month) and Tirosint Direct ($65/month) can significantly reduce out-of-pocket costs.
