Diarrhea can be a side effect of any antiparasitic medication. As long as Butter is behaving normally otherwise, you can manage it at home. Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amount until symptoms resolve. Begin with 1 tablespoon of food every hour and gradually increase the amount. Feed bland until the stool is normal then transition slowly to the regular diet. Symptoms to monitor for and that should be addressed by your veterinarian include lethargy, vomiting, persistent diarrhea, loss of appetite or abdominal pain.
