  • Methimazole

What is methimazole transdermal gel used for in cats?

Veterinarians commonly prescribe methimazole to help manage hyperthyroidism in cats by reducing excessive thyroid hormone production. The transdermal gel format offers an alternative for cats that are difficult to medicate with oral tablets.

How do I apply methimazole transdermal gel to my cat?

Apply the prescribed volume to the clean, dry, hairless inner ear flap (pinna). Wear gloves, spread a thin layer as directed, and alternate ears as advised. Do not place the gel inside the ear canal.

What does 12.5 mg/mL mean for dosing?

The concentration is 12.5 milligrams of methimazole in each milliliter of gel. Your veterinarian will prescribe a specific volume (mL) to apply per dose based on your cat’s needs.

What side effects should I watch for?

Possible effects may include decreased appetite, vomiting, lethargy, facial itching, or local ear irritation at the application site. Less commonly, blood or liver changes can occur. Contact your veterinarian if you notice concerning signs.

Can I switch between methimazole tablets and the transdermal gel?

Only under veterinary guidance. Oral and transdermal formulations may not be dose-equivalent, and your cat’s thyroid levels should be rechecked after any change in formulation or dose.

How long will my cat need methimazole?

Hyperthyroidism often requires long-term management. Your veterinarian will tailor duration and dosing and will recommend periodic lab monitoring to guide ongoing therapy.

How should I store and handle this medication?

Store as labeled, protected from heat and light, and keep out of reach of children and other pets. Wear gloves when applying, avoid contact with your skin or eyes, and wash hands after handling.
