I think I’m the most experienced BB member in regards to ringworm, haha. Take deep breaths, and don’t worry— it will be okay!
Contagious: Generally speaking, a lot of the fungal infections (aka ringworm; more of a descriptor of what it looks like, but at the root, it’s a fungal infection) that cling to rabbits are not the same as those that stick to humans. My vet did cite a case where a guinea pig got ringworm and all the family got it at the same time, but considering it’s been a while since you’ve noticed it, most likely, both you and your husband will be fine. Myself and Wick’s other parent have never contracted ringworm from Wick. We do not have other pets, so I cannot speak about your cat, so I’d just monitor. My instinct is if your cat hasn’t gotten yet, he/she probably won’t.
Medications: There are rabbit-safe medications for ringworm. Itraconazole is personally one of Wick’s FAVORITE antibiotics. It’s used to help boost your rabbit’s ability to fight it so it does not spread (as quickly or at all) to other regions. He’s been on it pretty much since November, once daily, and in the past month we’ve ramped it down to once every two, three, and now we’re on four days. So both short-term and long-term, it is not dangerous. Wick is 2lbs and he has a higher dose of 1.1mL. It used to only be 0.8mL, but he kept contracting ringworm again so we boosted it up. Other safe medications I’ve used are:
1) Silvadine (silver sulfadiazine) – This is a topical cream that veterinarians give for a number of reasons, including treating urine scald on rabbits to actual human beings who have burns.
2) Clotrimazole (dogs & cats) – This is a topical medication that has the consistency of water, which you dab onto the area and it gets absorbed. As stated on the bottles I have, this is advertised for dogs & cats who are combating ringworm; however, it is safe for rabbit use.
— Both Silvadine and Clotrimazole are safe for rabbit use and even rabbit ingestion. The amount of time Wick spends grooming himself after topical treatment time is substantial. The worse thing that can happen is your rabbit gets grossed out because Silvadine has a metallic taste (says his veterinarian).
Treatment Vs. No Treatment: I can understand why your veterinarian suggested waiting it out first. Is your rabbit young? According to Wick’s vet, it takes a bit of time for rabbit’s to develop antifungal properties on their fur/skin, thus younger rabbits are more susceptible to contracting ringworm. Regardless of age, any rabbit with a suppressed immune system can become more susceptible to anything, not exclusive to ringworm. Some rabbits can fight off the infection on their own, using their own immune system’s strength. Some rabbits, such as younger rabbits (less than 1yo or around that age) or rabbits with weaker immune systems, may not be able to, and this will translate into the affected area getting bigger or more patches appearing. If this begins to occur, medical intervention is something I highly recommend. Wick’s vet has deemed Wick to be pretty susceptible to ringworm, as he’s on the final stretch of his 3rd wave since November; however a combination of the long-term itraconazole administration (building up that antibiotic’s presence in his body), me getting better at the topical application, and Wick aging has made Wick pretty clear of it. Currently, he only has some around his mouth, which is where it always starts for him and goes back across his face/shoulder. The current wave has stayed at his mouth for over a month now, so it’s pretty much gone.
… Specifically, you asked me about why I swapped/stopped between the topical applications. When Wick first got ringworm, I was given silvadine, which is essentially a lotion. I’ve learned now that while it’s important to be thorough and cover the entire affected area, it’s also very important to apply in moderation to lessen how much your rabbit will groom (i.e. don’t put too much on that the skin can’t absorb, similar to human lotion application, and trying not to get any on actual fur because that’s hard to groom off for a rabbit). So when Wick got ringworm a second time, I requested another topical treatment because my messy silvadine application would gum-up Wick’s fur and I’d have to cut off clumps, and he’d over groom some fur and that’d make their texture weird… So we got clotrimazole. Clotrimazole absorbs pretty much right away, but I found after multiple days of usage, Wick’s skin would get flaky (in a good, improvement way), and this would cause him some irritation. It was sort of like it was drying out his skin and irritating him whenever I’d go to do the next day’s application. So presently, I alternative between the silvadine (moisturizing) and the clotrimazole (drying), and that’s been working really well. Itraconazole has never been stopped ever. We’ve just upped the dose to help a bit. It’s also important to have a probiotic to pair with an antibiotic to prevent any stomach issues. GI-wise, Wick has been fine and dandy throughout all of this.
A few things that would be helpful to know:
1) Where is the patch?
2) How large is it, and has it grown since you first saw it?
3) Are there other patches?
Feel free to ask any questions!
