My kitten died after antibiotics for worms. What could have happened?

Pet's info: Cat | Mixed Breed | Female | 2.2 lbs

What are the side effects of antibiotics on kittens? Few days back I took my kitten, having worms, around 4-5 months old, to an animal hospital. There, the doctor gave it some injections of antibiotics and other medication. The antibiotics didn't suit it and she died.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry for the loss of Kitty! The most common side effect of antibiotics is tummy upset: vomiting, diarrhea or not wanting to eat. My concern is that there was something else going on with Kitty. If she had a large parasite load maybe when the dewormer killed them it caused an obstruction or intussusception. I also wonder what symptoms she had when you took her to the vet and what the other injections she received. Antibiotics are not typically prescribed for just worms. I'm assuming more than just worms were affecting Kitty. Again I am sorry for you loss. Feel free to post again with further details or questions. I hope this helped in some way.
