Can dewormer cause diarrhea in cats?

I gave my cat a dewormer last night because he's been having some bowel issues, but now it seems worse with diarrhea throughout the day. Is it normal for a dewormer to cause this kind of reaction, or should I be concerned about his health and reach out to our local vet?

Answer

It's concerning when your cat's symptoms seem to worsen after giving medication. Diarrhea can sometimes occur after administering dewormers, but it's essential to monitor your cat's overall health closely.

  • Diarrhea can be a common side effect of deworming.
  • Monitor additional symptoms that may indicate a more serious issue.
  • Consult a vet if symptoms do not improve or worsen.

Dewormers are generally safe, but some pets may experience gastrointestinal upset, including diarrhea. This can be a result of the worms being expelled or a reaction to the medication itself. If your cat seems well otherwise - meaning they're eating, drinking, and behaving normally - it might be a temporary side effect. However, persistent diarrhea can lead to dehydration or indicate a more severe issue, so it's best to err on the side of caution.
