Question:

How long for roundworms to come out after Panacur doses?

I'm feeling pretty stressed, and I could really use some advice. My dog, Max, has been diagnosed with roundworms, and we just started him on Panacur a couple of days ago. I've never dealt with this before, and I'm freaking out a bit. How long does it usually take for the worms to start coming out after you begin treatment with Panacur? I've been checking his stool obsessively, but so far, I haven't seen anything resembling worms, and I'm worried that maybe the medication isn't working or I’m doing something wrong. Our vet said it should work, but I can't help but feel anxious waiting to see some progress. Has anyone else been through this? How long did it take before you noticed a change? Any tips or reassurance would be super helpful right now. Thanks so much for listening!

Answer:

Hello there! It’s great that you're reaching out with your question about Panacur and roundworms. Panacur, or fenbendazole, is a commonly used medication to treat roundworms in pets, and it typically starts working within a few days.

After giving your pet Panacur, you might notice worms being expelled within 48 to 72 hours. This can often be seen in your pet’s stool, which is a good sign that the medication is taking effect. It’s important to complete the full course as prescribed, even if you start seeing results early, to ensure all the parasites are eliminated.

While you’re treating your pet, maintaining a clean environment is key. Regularly clean up and dispose of feces to minimize reinfection. Washing your pet’s bedding frequently also helps in keeping the environment worm-free.

Keep an eye out for any signs of serious issues such as persistent vomiting, diarrhea, or weight loss, and if your pet seems unusually lethargic or shows signs of distress, it could suggest a more severe infection or reaction to the treatment.

If you're concerned about your pet's condition or have further questions on the process, a video consult with one of our veterinarians on Dial A Vet can provide you with more personalized guidance and peace of mind.

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
