(redirects here from azulfidine)

Read on to learn about sulfasalazine for dogs, the dosage for dogs, safety guidelines, side effects and more.

Sulfasalazine (sometimes known as “Azulfidine”) inhibits the production of chemicals in a dog’s body which are responsible for causing inflammation. It acts mainly in the intestinal region, and is used most often for treating Inflammatory Bowel Disease (IBD), Chron’s disease and colitis, though it is also used for treating certain forms of arthritis.

Sulfasalazine dosage for dogs

 
The most common dosage of sulfasalazine for dogs is 5 – 10 mg/lb body weight given three times a day (8 hour intervals). You should never administer more than 1 gram (1000 mg) of sulfasalazine in any one dose regardless of your pet’s weight.

Is sulfasalazine safe for dogs?

 
Sulfasalazine is a prescription only medicine which means you will need to visit the vet first before you can use it. When used with professional advice and approval from a vet, your dog should be safe. Dogs who do not receive this medicine when they need it are at greater risk than those who take it in most cases.

Safety precautions

  • Get a prescription before giving sulfasalazine to your dog
  • Avoid use in pets with intestinal/urinary tract blockages or dogs with porphyria
  • Notify the vet if your pet has ever had a bad reaction to sulfa-based substances
  • Notify the vet if your dog is suffering with a fever, kidney/liver disease, jaundice or blood dyscrasias
  • Inform the vet of any other medication or substances your dog is taking
  • Avoid use in pregnant dogs

Sulfasalazine may interact with several other substances, so you should never give a new medication or supplement to your dog without first checking it over with your vet. Dogs suffering from kidney/liver problems, jaundice, fever and blood dyscrasias are at a heightened risk. You should avoid giving this medicine to pregnant dogs.

Side effects of sulfasalazine use in dogs

 
You should notify the vet if your pet suffers any side effects. Typical reactions include vomiting, headache, rashes/hives, itching and drying of the eyes. Other unforeseen side effects may develop and should be checked over.
