Sulfasalazine is used to treat inflammation of the bowel in dogs, cats, and other pets. Keratoconjunctivitis sicca (KCS, dry eye) may occur with long-term use of sulfasalazine, especially in the dog. Stop giving the medication and consult your veterinarian if your pet experiences discharge from the eye, redness of the eye, squinting, or other signs related to the eye. Consult your veterinarian if your pet experiences depression, vomiting, loss of appetite, pale gums, tiredness, bleeding tendencies, fever, increased thirst or urination, skin rashes, itchiness, or jaundice (yellowing of the gums, skin, or whites of the eyes), increased rate of breathing, weakness, confusion, seizures, or facial swelling while being treated with sulfasalazine.


Keep this and all other medications out of the reach of children and pets.
