Hilarious and pitiful to read comments regarding inability to get this medication. Take a deep breath people and chill. Chewy IS NOT responsible!!! It's a manufacturer issue hindering all vets and online orders . Move on and try something else. Hopefully your pet will be thankful you're open to trying an alternative. ✌️

Better than the veterinarian

I went to my veterinarian and he ordered these eardrops, but he said we don’t have them. They’re backordered from the manufacturer and he gave me something else. My cat hated those other drops and would not let me put them in so I went online and started looking for the drops he’s supposed to have and I found them at chewy. I called them told the vet wanted me to have them, but they didn’t have any available and they got a prescription for me and I received the eardrops the very next day. I was worried because these drops need to be refrigerated at all times, but they sent them in a special box with ice packs and they were kept cold at all times. I was very happy with the speediness that they were able to get me the prescription and send me the drops. Even though my cat still, hates eardrops, he’ll at least let me put these in. By the way, it was cheaper at chewy than it was at the veterinarian.

Cat vomits each time.

Dr said my cat had a little ear infection. Her fist dose was in office. Then she came home and was vomiting everything. I got her a slow feeder and only gave her oz of food at a time. Then I forgot to give ear drops and the vomiting stopped. Called vet she said not ear drop issue. So I have again. Non stop vomiting. So today. I let her eat. No drops. no vomit. Let her food settle and right before bed our towels down have drops. Within seconds all her food came up. Gagging type of vomiting. Confirming it has to be this. No she will be sick for the next 8 hours. Vet said there is no other approved eat infection drops for cats???

I used these drops for several of my cats and dogs. Now all of a sudden you can’t find them at the vets or chewy. What’s the deal?? I asked to be notified by vet n chewy still none available. It’s the only thing that works-where can I get it!????

Soothing and efficient

My cat developed sores, and despite antibiotics, they were lingering. Seth had to wear an Elizabethan collar for more than a month. A friend recommended Tresaderm, so I wanted to give it a try. It was difficult to find as the stock was back ordered everywhere except Chewy.. Got it in record time! My cat was comfortable with it, especially since you can take the collar off 15 minutes after applying. He then healed fast, and I am very satisfied with both Chewy, and Tresaderm

Multi-use medication......

Have kept this med on hand for years. Initially used for ear infection/irritation but Vet said it is appropriate for minor skin allergy flares which my boy has infrequently. Used this on previous pups and It works like a charm for us. Unfortunately it's currently back-ordered and impossible to obtain currently.......

Good experience

Received in reasonable time, on ice as it's a refrigerated medicine, at a considerably better price than the vet's office.

This service is awful

I have been waiting a week for my prescription and just now I found out the Tresaderm is out of stock. This is inexcusable. I know that the product is good, but I would never recommend that a friend order a prescription from Chewy.

This product works!

I just adopted a 5 year old Maine Coon from California, upon taking her to my vet not only did she have a serious eye infection but her ears were very dirty. The vet said use this product twice a day for a week. Amazing with in 2 days I could see a difference and was able to clean them. Today 8 days later they are clean and no more pawing at her ears. The eyes will take a while longer but she is improving daily. PS. I could not find this product at local stores. I called Chewy they verified the Rx and shipped it out asap. Thank you CHEWY!!

Great price

My dog has chronic ear infections. I was purchasing through my vet, however, at a much higher price. Thanks Chewy for helping me save some money.
