If you're caring for an older cat with thyroid disease, you’ve likely been told by your veterinarian that they'll need daily medication, possibly for life.
The most common thyroid condition in cats is hyperthyroidism. Hyperthyroidism occurs when the thyroid gland produces excess thyroxine (T4), increasing metabolism and placing strain on the heart and kidneys.
While hyperthyroidism is by far the more common thyroid disorder in cats, the opposite condition, hypothyroidism, can occasionally occur, especially after treatment (often following surgery or radioactive iodine treatment). Hypothyroidism occurs when the thyroid gland produces too little thyroxine (T4), slowing metabolism and reducing energy throughout the body.
But what if you live in a rural area and need thyroid medication for cats fast? And what if your cat is extremely picky and turns their nose up at anything but chicken?
The good news is, there’s a simple solution.
Yes! Many compounding pharmacies (including Mixlab) offer thyroid medication for cats in chicken flavoring.
We carry one of the most common treatments for feline hyperthyroidism: compounded methimazole for cats. Methimazole helps by blocking the enzyme thyroid peroxidase, which reduces new thyroid hormone production and stabilizes hormone levels.
Compounded methimazole for cats can be formulated as either oral liquids or transdermal creams. Because methimazole’s plasma half-life in cats is only 6-8 hours, consistent twice-daily dosing helps maintain steady hormone suppression and prevents rebound T4 elevations. For cats that resist oral medication or experience GI upset, transdermal compounding offers steady absorption through the skin of the inner ear.
When hypothyroidism develops, veterinarians typically prescribe levothyroxine, a synthetic form of T4. Levothyroxine restores normal hormone levels and supports healthy metabolism, body temperature, and organ function. Consistent daily dosing helps stabilize thyroid hormone concentrations and prevent fluctuations that could impact cardiovascular and renal health. Mixlab can also compound levothyroxine into flavors your cat actually enjoys.
In fact, Mixlab offers 30+ flavor options. Besides chicken, other popular flavors include fish, tuna, salmon, beef, bacon, marshmallow, liver and more, depending on the specific thyroid medication for cats that is prescribed by your veterinarian. When you get your prescription filled through Mixlab, you’ll be able to browse all of our available flavors through your secure checkout link.
For picky senior cats, having a palatable option like chicken or tuna can make all the difference when it comes to keeping up with their medication regimen.

Yes, when properly prescribed and monitored, compounded methimazole for cats is considered safe and effective for long-term management of hyperthyroidism. Because methimazole works by blocking new thyroid hormone production rather than destroying thyroid tissue, it allows for ongoing control without irreversible effects.
However, long-term use requires regular veterinary monitoring to ensure safety and optimal dosing. Your veterinarian will typically recommend:
In cats with sensitive stomachs, transdermal formulations can minimize gastrointestinal irritation while maintaining stable blood levels. At Mixlab, each compounded formula is made to USP <795>, <797> and <800> standards for accuracy, stability, and purity, so your cat receives consistent dosing with every refill.
It’s simple, just ask your veterinarian to prescribe through Mixlab. Because thyroid medications require precise dosing, especially for small cats, it’s critical that compounding follow strict USP standards for accuracy and stability. Mixlab’s PCAB-accredited facilities use validated methods to ensure every compounded methimazole suspension or cream delivers the same dose, every time.
