side effect of medicine?
jbroyles8 posted:
Hi, my question is about a broad-spectrum dewormer that my vet prescribed for my cat. I believe that it's called Drontal.
He's an outside tabby cat and weighs 12.6 pounds. I took him to the vet last week for a wellness exam. At that time, he was having loose stools and his inner eyelids were half-way out. The vet said that his physical exam was fine, but that he had tapeworms. So, she prescribed the broad-spectrum dewormer.
I gave him 2 pills as directed by my vet. It has been 6 days since he took the dewormer. For the last 2-3 days, he hasn't been eating, he's had diarrhea, and he vomitted this morning. Could the dewormer be causing these symtpoms this long after taking the medicine?
Also, he was is being treated empirically with an antibiotic, Amoxicillin. Although, he has taken this antibiotic before and didn't exhibit any of these symptoms.

jbroyles8- if your cat's 3rd eyelids were protruding prior to the exam and deworming, I'd be concerned that this is something other than the Drontal- which usually has no side effects. I'd go back for another exam with your vet and discuss a diagnostic work up (blood work, viral tests, additional fecal test/culture, etc.). This sounds like something more than tapeworms. Best to you and your tabby.

Drew Weigner, DVM, ABVP responded:
What you're describing sounds like "Haws Syndrome" which is a partial elevation of the third eyelids occasionally seen in cats with intestinal disease. While there's no treatment for the eyelids, it usually resolves several weeks after the intestinal disease. If your cat still has diarrhea, that needs to be treated and another trip to your veterinarian may be in order.
