Imodium (Loperamide)


Imodium is used for the treatment and control of diarrhea. 

  • Imodium should not be used in cats as it may cause hyper excitability.
  • Collies, Australian Shepherds and mixes of these breeds may be more sensitive to Imodium and should be used only if approved by your veterinarian. For such breeds, Pepto Bismol may be a better choice.
  • If you have any concerns about giving your pet Imodium contact your veterinarian first.


To use this "dose caluculator" just enter your pet's weight (in pounds) in the yellow box below (place your cursor in the yellow box and "left click" your mouse...this will select the box...then you can enter the weight) and press enter. If you are unsure of your pet's weight you can use a household scale. If you chose to estimate a weight make sure to under estimate the weight. When in doubt it is always better to give less of a medication instead of more.
