What are the side effects of furosemide in cats?

I recently started giving my cat furosemide as prescribed by the vet, but I'm worried about possible side effects. She's been drinking a lot more water and seems a bit lethargic since starting the medication. Are these normal reactions to furosemide, or should I be concerned about something more serious?

Answer

It's understandable to be concerned about changes in your cat's behavior after starting furosemide. Increased thirst and lethargy could be common responses, but monitoring for more serious symptoms is wise.

  • Increased thirst is a known side effect of furosemide.
  • Lethargy might occur but should be watched closely.
  • Always consult your vet if you notice ongoing or worsening symptoms.

Furosemide is a diuretic often prescribed to cats to help remove excess fluids from their body, and increased thirst is a typical response due to this function. Lethargy can also happen as your cat's body adjusts to the medication, but it should not persist or be severe. Always monitor your cat for any additional side effects like vomiting, refusal to eat, or difficulty breathing, and contact your vet if you have concerns or if the lethargy continues.
