What is Salix?

Salix is an oral medication that acts as a diuretic to help draw excess fluid off of the body that accumulates due to heart failure, kidney failure, and other medical problems. It may also be effective in treating high blood pressure (hypertension).

What are the benefits of Salix?

  • Easy to give.
  • Can remove extra fluid from the body caused by congestive heart failure, heart problems, kidney problems, and other conditions.
  • May also help in the management of hypertension (high blood pressure).

How is this medication given?

Give Salix by mouth exactly according to your veterinarians instructions with or without food. Make sure your pet has access to water at all times while on this medication.

If you have any questions regarding the use of Salix, contact your veterinarian.

How does this medication work?

Salix is a diuretic that blocks the absorption of salt and fluid in the kidney tubules causing an increase in urine output. This helps rid the body of excess fluid.

What results can I expect?

Salix helps to relieve the symptoms associated with your pets excess fluid accumulation (edema) but it will not cure the primary problem. This will help improve your pets quality of life.

This medication is quick acting so you may notice a difference in your pet quickly. Salix is very short-acting so it needs to be given on schedule in order to continue to see results.

    Thank You for the Furosemide

    By Gobi on Jul 6, 2020

    It was convenient to be able to order this medication for my pug; my vet can provide it as well, but the convenience of mail order, and not having to go in to pick it up, is great

    Smooth process

    By ScoutsMom on Nov 21, 2019

    The med is working well for our pup's heart condition. I write this review to give a thumb's up to Chewy for contacting my vet for approval. Entire process took only a few days and I had the med within a week. Smooth.

    Our 12 year old "puppy" has been taking this med for 5 years and our vet is pleased with her clear lungs. Chewy can't be beat on pricing, service and FAST shipping!

    Absolutely thrilled with this purchase!

    By RStones98 on Apr 3, 2019

    My cat has been on this med for a couple of yrs now, and I have always gotten it thru her cardiologist. Problem is that 95% of the time the Furosemide they receive is from a different manufacturer and is particularly difficult to split (barely scored, so it's inevitable that one half always crumbles, so you worry your pet is not getting the full/correct dose). I was thrilled to see that Chewy carries the Salix brand of Furosemide because the score is very pronounced, making it super easy to split without any crumbling. Now, splitting is a breeze, I know kitty is getting the full/correct dose each time, and, I'm saving $$ :)

    It must be bitter

    By avawava on Oct 24, 2018

    When I first started my dog on furosemide, the cardiologist prescribed a generic and my dog swallowed them just fine along with her Vetmedin, which she seems to really love. However, when I switched over to the Salix brand of furosemide, she started spitting out just the furosemide. These pills are tiny, yet this Salix brand must have a noticeable flavor or smell. Now I have to be extra careful to hide them in with her Vetmedin tabs. If she spits them out, I have to force her to take it. I close her mouth and blow on her nose, which forces her to swallow. It works, most of the time and/or eventually. :/
