Help Ease Your Cats Symptoms and Hyperthyroidism Methimazole Compounded Transdermal Gel Specially Made to Provide:
  • Treatment for overactive thyroid glands in cats
  • Lessen symptoms of hyperthyroidism for a better quality of life
  • Precise dose made just for your pet’s needs
  • Transdermal-easy to dose on your cats ear

Methimazole Compounded Transdermal Gel is an ExpressVet exclusive medication. If your cat is losing weight despite eating regular meals along with being thirsty and urinating more frequently this could be a sign of an overactive thyroid. Methimazole is a medication prescribed by veterinarians to treat hyperthyroidism, also known as overactive thyroid problems. The main ingredient methimazole, works by reducing the amount of thyroid hormone that the thyroid gland produces. For cats that cannot tolerate oral medication the gel formula is preferred because it can be applied on their skin which makes it easier to give in doses.
Symptoms of an overactive thyroid are increased appetite, hair loss, thirst, and weight loss. There is no cure of hyperthyroidism, however, this medication will treat the symptoms so they can feel better and live a better quality of life.
Available by prescription only, the gel is easily applied to the inner part of your cat's ear which is then quickly absorbed into the bloodstream. Help your cat feel better with Methimazole Compounded Transdermal Gel today!

Dries skin, not as good as calamine lotion
For eczema, this soap is counter-productive, as it dries my skin and makes it worse, from what I can tell. As a treatment for rash, insect bites, or other “topical” needs, it is a poor form factor. To get any benefit you have to really lather up the affected skin and be careful to not wash all the soap off. I couldn’t tell it was helping at all on a spider bite, whereas with normal calamine lotion the relief is immediate. So, what is the point then? Normal calamine lotion can be precisely applied, is more durable, and is easier to detect when re-application is needed. Nice idea, but it seems impractical. The soap is only lightly scented, which I prefer, but comes in a very small bar for the price point.

This stuff works!!
Scent: Fragrance-Free - Standard Size
This set has been the absolute best shampoo, lotion, and ointment for my little one going through a tough spell of baby acne. The ingredient list is clean, and worked miracles quickly. Baby’s skin was so soft, the redness disappeared within days. After just the second wash I could really notice a difference. Thank you Tubby Todd!

Perfect gentle routine for newborn skin
Scent: Lavender Rosemary - Standard Size, Scent: Lavender Rosemary - Standard Size
We started using the Tubby Todd 3-Step Baby Bath & Skincare set when our baby was just weeks old, and it has been amazing for delicate newborn skin. The Hair + Body Wash is extremely gentle and doesn’t irritate or dry out the skin. It rinses clean and has a very mild, pleasant scent. The Everyday Lotion keeps our baby’s skin soft and smooth without feeling heavy or sticky. It’s perfect for daily use after bath time. The All-Over Ointment is great for extra-dry areas, especially around the cheeks and legs. It creates a protective barrier that helps prevent dryness, especially in cooler weather. We appreciate that this brand avoids harsh chemicals and focuses on clean, baby-safe ingredients. This routine has become part of our nightly bath time and has kept our newborn’s skin healthy and moisturized. Would absolutely recommend this to new parents looking for a safe, gentle skincare routine for their baby.

It didn’t work for my baby
Scent: Fragrance-Free - Standard Size
Update on my review: gave it 5 stars because the customer service is great!!! Thank you uso much! I’m sorry this product didn’t work out for my little one. But thank you for having a great customer service! I’ve been using the products for about a week now and haven’t noticed any improvement in my baby’s skin. I do appreciate that the ingredients are clean, fragrance-free, and that the ointment is thick and suitable for eczema. However, I’ve seen other reviews mentioning results within a few days, and unfortunately, that hasn’t been my experience. For me, it wasn’t worth the money. At first I thought my baby had ringworm but I took him to his pediatrician and she said it’s a mild eczema, I don’t want to do steroid lotion, I purchased this hoping it would help and it hasn’t
