Why Tirosint is different

Tirosint represents a change in oral T4 treatment—a pure formulation that contains only T4, water, glycerin, and gelatin.

Tirosint is available in 10 dosage strengths housed in blister packs to protect Tirosint from light and moisture. Blister packs are also clearly marked for daily dosing.

Tirosint is unique and has no generic substitute. If your doctor prescibes it, check your prescription before leaving the pharmacy to be sure you are getting the Tirosint your doctor asked for.

Tirosint is administered as a single daily dose, preferably one-half to one-hour before breakfast. Tirosint should be taken at least 4 hours apart from drugs that are known to interfere with its absorption. Due to the long half-life of levothyroxine, the peak therapeutic effect at a given dose of levothyroxine sodium may not be attained for 4-6 weeks.

Tirosint should be protected from light and moisture and stored at 25°C (77°F); excursions permitted to 15°-30°C (59°-86°F).

Unlike levothyroxine sodium tablets, Tirosint capsules cannot be cut or crushed.
