Thyroid Hormones

Levothyroxine (T4), liothyronine (T3), and combination T4/T3 preparations for hypothyroidism — compounded without the fillers and dyes that some patients cannot tolerate.

About Thyroid Hormones

Thyroid hormone replacement uses synthetic levothyroxine (T4), liothyronine (T3), or combination T4/T3 preparations. Commercial levothyroxine tablets contain dyes, lactose, and other excipients that a subset of hypothyroid patients cannot tolerate; compounding pharmacies can prepare hypoallergenic T4, T3, or combination capsules in exact microgram strengths. Compounded T4/T3 blends are requested by clinicians who titrate combination therapy outside the fixed ratios of commercial products like Armour Thyroid or NP Thyroid. Veterinary thyroid protocols (methimazole transdermal for feline hyperthyroidism, T4 for canine hypothyroidism) are also commonly compounded.
