I found some other information on medicine that you could use on rabbits and wanted to post it here:
Some bunnies, especially the Rex breed, are prone to developing sore hocks. Periodically, examine the soles of your bunny's rear paws to see if the fur has worn off and red sores are evident. Ulcerations and cracks in the skin pose a health risk because they are entry points for bacteria. A good healing remedy is Zymox Topical Cream - Hydrocortisone Free. You can find it on-line. It is wise to keep a tube on hand to apply to any cuts or scratches. Be sure to get the Hydrocortisone FREE Zymox. It is also great for healing any scratches or surface wounds on rabbits. Pet Nutrition Products sells a one ounce tube of "Zymox Cream without Hydrocortisone for Dogs and Cats" for $9.49, plus shipping/no tax. For our bunnies that are prone to sore hocks, we place a layer of fleece padding in their cages, rather than the rougher rugs we typically use.
- Lop-eared rabbits are prone to ear infections because their floppy ears cover the ear canal, keeping it moist and habitable for germs. You can keep the ear canal dry with Zymox OTIC Solution without hydrocortisone. The product can be found online from Pet Nutrition Products:
http://www.petnutritionproducts.com 866-473-8432. A small, 1.25 ounce bottle, "Zymox OTIC Solution without Hydrocortisone for Pets" was $12.89 plus shipping/no sales tax. The National HRS website
www.rabbit.org offers advice for applying ear drops: "Rabbits like to have their ears stroked. They generally are not big fans of having liquid squirted down there though. That means that sometimes rabbits are most uncooperative about this procedure. You can try administering ear drops while on the floor, but it's often easier to do it on a tabletop where you can secure her with one hand." "The first trick with ear drops is to get the nozzle pretty close to the ear's actual opening (never push anything down beyond the opening.) That way, when the rabbit shakes her head, the medicine will go down into the ear instead of all over your kitchen. The second trick is to try not to hit the inside surface of the ear with the nozzle itself. This tickles and it will make the rabbit shake her head, which makes it very hard to aim. Once the drops are in, you can massage the base of the ear to help it go down and get spread around." "A portion of the outer ear is composed of a bent canal that goes vertically and then almost horizontally to lead to the eardrum. This portion of the ear is prone to buildup of earwax and debris, which may then become a breeding ground for infection. Many rabbits can deftly clean out any accumulation with a back toenail, but lops and infirm rabbits may need a bit of help. Since the ear canal has a bend, this can be done fairly safely. Your veterinarian can show you how." Some up-eared rabbits are also prone to earwax buildup, a good reason for twice yearly vet check ups.
