Spironolactone can also be used to treat conditions involving potassium deficiency.

FarmVet Tip: 
Ask your sales representative about pill pockets! Picky animals can be tricked into taking their medication if it’s hidden inside a treat.


  • Make sure your veterinarian knows all the other medications your animal is on, as spironolactone can increase the potency of some other medications.
  • Do not use in animals with kidney problems, hyperkalemia, or Addison’s disease. 
  • Be cautious in using spironolactone in pregnant animals, as some side effects have been reported in humans.
  • Do not give potassium supplements while your animal is on this medication.
  • Spironolactone can cause dehydration or an imbalance in electrolytes.
