ursodiol

Generic Actigall
Used for Cirrhosis, Gallstones

Ursodiol is a bile acid medication used for dogs and cats with certain liver or gallbladder problems. It helps clear out thick gallbladder sludge and protects the liver. Vets use it in pets as an off-label medication because there isn’t an FDA-approved version for animals. Ursodiol comes in tablets and capsules, but some pharmacies can make it into a liquid if needed. The dose depends on your pet’s weight and is usually given with food once or twice a day. The most common side effect is diarrhea.

What is Ursodiol for pets used for?

  • Gallstones made of cholesterol in dogs and cats
  • Gallbladder problems in dogs and cats (e.g., too much gallbladder sludge, inflammation)
  • Inflammation related to liver problems in dogs and cats

How Ursodiol for pets works

Ursodiol is a bile acid. It helps bile flow better through the liver and into the gut. This helps lower the buildup of bile in the body, which can lessen damage to the gallbladder and liver.

Ursodiol also lowers the amount of cholesterol your pet’s liver makes. In addition, it lowers how much cholesterol their body absorbs from food. This helps reduce the amount of cholesterol in gallstones.

Pharmacist tips for Ursodiol for pets

pharmacist
  • Ursodiol works best if your pet takes it with food. You can try hiding the tablet or capsule in your pet’s food when they take it. Or, you can feed your pet before giving the medication.
  • Don't cut ursodiol tablets or open the capsules unless your veterinarian says it's okay. Only the ursodiol 500 mg tablets have a line across them called a score line. This line shows where you can break the tablet in half. You can keep the half-tablets of the 500 mg tablets in the original bottle for up to 28 days before they're no longer safe for your pet.
  • Your vet might prescribe a liquid version of ursodiol that’s made by a compounding pharmacy. This is an option if your pet’s dose isn’t available in pill form or if your pet has trouble taking the pill.
  • For compounded liquid ursodiol: Follow your pharmacist and vet’s instructions for how much of the liquid to give to your pet and how to store it. Always use a dosing syringe or cup from the pharmacy to measure out the medication so your pet gets the right dose. Don’t use household spoons since your pet might not get the correct dose if you use them.
  • Talk to your pharmacist or vet before giving your pet other medications. Most are safe to take with ursodiol. But it can interact with some medications. Examples include sucralfate, cholestyramine, and antacids containing aluminum like Mylanta.
  • Place bowls of fresh water around the house in places where your pet likes to go. Along with ursodiol, making sure your pet stays hydrated is important to help their bile flow better.
