Question:

Vet gave my cat the wrong dosage

I'm really in need of some advice or reassurance right now. I just got back from the vet and I'm absolutely panicking. I took my cat, Mittens, in for her usual check-up, and the vet prescribed her medication for a slight thyroid issue they detected. I got home, gave her the medicine as instructed, but then I noticed the dosage on the bottle didn’t match what we had discussed during the appointment. The bottle says to give her twice the amount the vet originally mentioned! I tried calling the clinic, but they’ve already closed for the day, and now I'm freaking out thinking I might have overdosed her. She’s my baby, and I’m terrified of the harm this could do to her. Has anyone else experienced something similar? What should I watch out for, and can I do anything to help in the meantime? Any advice would really help calm my nerves. Thanks in advance, everyone.

Answer:

Oh no, I'm really sorry to hear about the mix-up with your cat's medication. Let's talk about what might happen and what you can do to help your furry friend right now.

Firstly, depending on the medication and whether it was an overdose or underdose, your cat might experience some different symptoms. For an overdose, you might notice things like vomiting, diarrhea, lethargy, or even more severe issues like difficulty breathing or seizures. In the case of an underdose, your cat might not show any immediate adverse effects, but their original symptoms might not be controlled or could worsen.

At home, you can keep a close watch on your cat for any unusual behavior or physical symptoms. Make sure they have plenty of fresh water and a calm, comfortable place to rest. It's important to avoid giving any more medication until you speak with a vet.

If you notice severe symptoms such as vomiting, difficulty breathing, or seizures, it’s crucial to seek veterinary attention immediately. Even if they seem fine now, reaching out for expert advice is always a good idea.

Booking a video consult with a Dial A Vet professional can provide specific guidance based on the medication and dosage involved. It's always better to be safe and get a vet's advice to ensure your cat's continued health and comfort.

The "Ask a Vet" forum on Dial A Vet offers general information and helpful tips on pet health, but it's not a substitute for professional veterinary care. The advice here doesn't create a veterinarian-client-patient relationship, and our vets can't diagnose or treat your pet remotely. For emergencies or specific medical concerns, always contact your local veterinarian immediately. Your pet's health is unique, and decisions should only be made after consulting with a qualified professional.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
