Question:

Osurnia side effects duration (in cat)

I'm feeling a bit worried and could really use some advice or reassurance. I took my cat, Whiskers, to the vet last week because she kept scratching her ears, and they diagnosed her with an ear infection. The vet applied Osurnia to her ears, and said it should clear things up. But since then, I've noticed she's acting differently. She's been more lethargic than usual, not showing much interest in her toys or even in her favorite spot by the window, and her appetite seems off. Has anyone else experienced these side effects with Osurnia in their cat? How long did it take for things to get back to normal? I'm trying not to panic, but it's tough seeing her like this. Any insights or experiences would be super appreciated! Thanks in advance.

Answer:

Hello there! I'm sorry to hear you're concerned about your kitty after using Osurnia. It's important to make sure they’re comfortable and safe.



Osurnia is typically used for ear infections in cats and dogs, and while it's often effective, some side effects can occur. You might notice your cat shaking their head more than usual, or perhaps some redness or irritation around the ears. These mild effects usually subside within a few days.



However, there are more serious signs to watch out for. If your cat shows signs of a skin rash, excessive scratching, or seems to be in pain or unusually lethargic, it’s important to seek help. Vomiting or changes in appetite could also be concerning.



At home, try to keep your cat's environment calm and monitor their ear closely. Avoid touching or manipulating their ears, as this can cause discomfort. If needed, gently clean the outer part of the ear with a damp cloth, but don't insert anything into the ear canal.



If your cat’s symptoms persist, or if you notice any serious signs, it’s best to consult with a vet. I encourage you to book a video consult with us at Dial A Vet for a thorough assessment and personalized advice. We’re here to help ensure your cat gets back to feeling their best!

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
