What is methimazole used for in cats?

Methimazole is an antithyroid medication commonly prescribed by veterinarians to help manage hyperthyroidism (overactive thyroid) in cats by reducing the production of thyroid hormones.

How do I dose this 1.25 mg/mL compounded suspension?

Follow your veterinarian’s instructions precisely. Shake well, then use the oral syringe to measure the exact milliliters prescribed based on the 1.25 mg/mL concentration, and administer by mouth.

How long will my cat need to take methimazole?

Hyperthyroidism typically requires ongoing management. Many cats remain on methimazole long-term with periodic veterinary checkups and lab monitoring as directed by your veterinarian.

What side effects should I watch for?

Some cats may experience decreased appetite, vomiting, diarrhea, or lethargy. Contact your veterinarian if you observe these or any concerning signs, or if your cat seems unwell after dosing.

Can I switch between tablets and a suspension or change formulations?

Always consult your veterinarian before changing forms or flavors. Formulation changes may require dose adjustments and monitoring to maintain appropriate thyroid levels.

What should I do if I miss a dose?

Give the missed dose when remembered unless it is close to the next scheduled dose. Do not double up; contact your veterinarian for guidance if you are unsure.

Any handling tips for this medication?

Shake well before each use, measure carefully with the dosing syringe, and wash hands after administering. Avoid contact with eyes and skin, and keep the bottle tightly closed and stored as labeled.
