Questions & Answers

7 Customer Questions

What are the different between Denamarin and Denosyl since they are both package by Nutramax?
Answer by ChewyAug 15, 2018
The central difference between the two medications is a second ingredient that is found in Denamarin but not Denosyl. This ingredient, silybin, provides additional liver support and can work in conjunction with SAM-e to promote healthy liver function. This means that Denamarin is a stronger supplement for pets that need maximum liver support.

Do you need prescription?
Answer by ChewyDec 26, 2017
These tablets don't require a prescription.

can I crush the pill and mix it on my cat's food? She is tough with medications but will eat anything with tuna :o)
Answer by ChewyJul 12, 2021

Purchased sent yo wrong place

I live in Florida I made a purchase on 8/25 and package was sent to Arizona than to California than sent back to the facility 6 days after and I still haven’t received it. Terrible service I called to report this issue and the only answer I received was Sorry !!! If you don’t need it send it back. Never use this company again.

Helping my cat's high liver enzymes.

My vet prescribed this for my 10 month old kitten Michelangelo, who has high ALT and they aren't sure why until they do a biopsy. The numbers are falling slowly but surely. I also give him milk thistle. I just ordered Denamarin which has both in it, but if you can't get Denamarin, or don't need milk thistle, this is great.

No Change, Not as Expected

The pill is pretty good size and what we didn’t realize is it had to be taken an hour before or 2 hours after eating. This doesn’t work for our old gal. She’s a feisty not well cat. To get a whole pill in is impossible. Can crush and put in food but that’s not what the instructions say

Denamarin is a great product-try Denasyl

I have used Deanmarin for years for Tawnie, my cat and he has recovered from a bad liver(Chewy first introduced me to it). Hey, try the Denosyl--- it is probably the next best thing. I'm sure it will do a good job for Tawnie. He has recovered; to maintain his liver as Denamarin did. And me and Tawnie love Chewy---it is THE BEST!!!

Finally can sleep

My veterinarian who is not only my mentor but a very dear friend recommended this product and it has made a big difference in our cat. He has cat dementia and has been yowling like a coyote day and night for the last two years which made it impossible to live in the house with him. He is still yowling but not nearly as much on a scale of 1 to 10 his yowling is about a one. I would recommend this product if you have this problem with your cat

Next Best Thing

Since Denamarin has been on prolonged back order, the Denosyl is the next best thing.

I had to order this twice through Chewy. On the first order I didn't have the correct dosage but I included a note saying to fill it per veterinarian and charge accordingly. Chewy canceled the prescriptions and did not notify me.

no difference

I gave this to my diabetic elderly cat for 2 weeks with no visible effect. She was diagnosed with liver disease and has suffered from diarrhea for a couple months now. I decided to take her off because I found an undisolved pill in her vomit over 24 hours after she had taken it.
