Is it safe to give my cat human penicillin, and how much should I give?

This morning, I noticed my cat seemed under the weather and remembered I have some leftover penicillin from a recent prescription. I’m wondering if it’s safe to give human penicillin to my cat, and if so, what would be the appropriate dosage? I don't want to accidentally harm her by giving the wrong amount. Can you advise me on what to do?

Answer

It’s natural to worry when your cat seems unwell, but administering human medications without veterinary guidance can be dangerous. It's not safe to give your cat human penicillin without professional advice.

  • Avoid giving human medications to pets without veterinary guidance.
  • Incorrect dosage can be harmful or even toxic to pets.
  • Consult your vet for appropriate treatment options.

While it might be tempting to self-treat your cat with medications you have at home, it's important to understand that pets metabolize drugs differently than humans do. Penicillin prescribed for people may not be suitable for cats and can potentially cause adverse effects. Only a veterinarian can determine the correct type and dosage of medication specific to your pet's needs. Please hold off on giving your cat any medication until you have consulted with a vet.
