Is oral Moxidectin safe for recurring bunny mange? What's the dose?

Updated on September 23rd, 2025

Pet's info: Small Animal | Rabbit | Female | unspayed | 2 years and 1 month old | 6 lbs

My bunny has sarcoptic mange. It has been recurring for a long time. My vet recommended Quest gel (Moxidectin) orally to minimize stress of ivermectin injections repeatedly. I have no idea what the recommended dose maybe since the vet told me he was a rabbit savvy vet! Please help me. If it is meant to be 0.2 mg per kg and she is 2.9 kg what would that be in ml? Not sure what the concentration is but I have attached a photo. Thank you! Please help

It looks as though this product is 2% w/v, which translates to 20mg moxidectin per ml. Based on that information, Moyel would receive 0.029ml according to your vet's directions. The Quest gel is labeled for exclusive use in horses and clearly states that it should not be used in other species. As a result, I would inquire further with your vet as to their planned course of treatment. Even if they feel comfortable prescribing this medication in an off-label fashion (which is commonly done!), the volume of medication appropriate for Moyel is so minuscule that it's next to impossible to achieve accurate dosing. I would instead ask if they have recommendations for topical treatments of moxidectin or selamectin if they're more comfortable using those medications rather than injectable ivermectin. I hope that everything goes well!

    I am unfamiliar with using this treatment course orally. Usually it is injections or a topical medication for external parasites in rabbits. I would contact your vet that prescribed the medication for Moyel to determine the dose and frequency.
