Methimazole is a medication used to treat hyperthyroidism (overactive thyroid) in pets, but especially cats. The medication used in the transdermal gel is the same as the tablets manufactured commercially but the difference is the delivery of the medication. Transdermal means across the skin. The transdermal gel is a thick gel containing methimazole which is applied to the skin of the pet and is absorbed through the skin to the bloodstream. The gel will arrive in syringes marked for easy dosing and administration. VetRxDirect will also supply some finger cots for you to place over your finger when applying the gel to prevent you from absorbing the medication. The advantages of the transdermal gel include not having to worry about giving your pet tablets and having a custom dose available for your pet.
Methimazole transdermal gel is not manufactured commercially so it is compounded by our expert pharmacy compounding staff. It is important to order your refills a few days ahead of time because the product needs to be made for your pet. Methimazole transdermal gel expires after 90 days after it’s been made, so pay close attention to the expiration date on your label. Quantities and charges ordered exceeding the beyond use date will be adjusted to hopefully prevent your pet’s medication from expiring before they are finished.
The compounds are made to fit the prescription we receive so virtually any strength can be made. This specific product is already available in 1.25 mg/0.1 mL, 2.5 mg/0.1 mL, 3 mg/0.1 mL, 3.5 mg/0.1 mL, 4 mg/0.1 mL, 5 mg/0.1 mL, 6 mg/0.1 mL, 6.25 mg/0.1 mL, 7.5 mg/0.1 mL, 8 mg/0.1 mL, 10 mg/0.1 mL, 11 mg/0.1 mL, 12.5 mg/0.1mL, 13 mg/0.1 mL and 15mg/0.1 mL. This means there’s x milligrams of methimazole in each tenth of a milliliter. A 1 mL amber syringe will contain 10 x the strength of methimazole total, so pay close attention to the dose your veterinarian prescribes and always ask questions you have. You may also call VetRxDirect with any questions you may have about dosing or this product in general.

Beyond Use Date:
Prescription Methimzaole transdermal gel provides fast, effective, long-term treatment of hyperthyroidism in cats. The gel, mixed for your cat’s specific dosage needs, reduces the amount of thyroid hormone produced in the thyroid gland.
Hyperthyroidism can be a life-long condition that causes a range of uncomfortable symptoms in cats. If your cat is suffering from hyperthyroidism, your veterinarian may prescribe Methimazole. This medication slows hormone production in the thyroid gland and can be used for long-term control of the condition. Exact dosing is critical to successful treatment so we blend the right amount of Methimazole into an easy-to-apply gel just for your cat. Just rub it right into your cat’s skin as directed by your veterinarian.
