Helpful Tips:

  • Tablets are optimally absorbed when given on an empty stomach at least an hour prior to feeding. The presence of food can decrease absorption.
  • If you have trouble administering tablets to your pet, you may disguise this product in a small bite of food.
  • Tablets given as a "dry swallow" to cats may not pass into the stomach, leaving them lodged in the esophagus. Pet owners should administer 3 to 6cc of water immediately after administering a tablet to speed passage.
