Or any other med combinations to try?

Yes, you could talk to your vet about adding Ponazuril (toltrazuril). It has been used off label (as most meds are for rabbits) to treat EC alongside panacur. Your vet will likely need to research it a bit.

I understand it does take while for panacur to take effect so hoping you’ll see more of an improvement if you’re only 5 days in so far. It’s the norm to do a 28 day course.

Also, thanks for posting about Tumeric. Do you find it helps? I’ve been wondering about it and whether it would help arthritic rabbits.

Ponazuril and Toltrazuril sulfone are one and the same. : )
It’s also been used for coccidia in rabbits.

I’m lucky enough to get fresh tumeric root and I throw it into a juicer and mix it with Pineapple juice (otherwise the tumeric is much too bitter).  It is definitely helpful with anti-infammatory issues, but I take it to hopefully ward off Alzheimers which is in my family. 

ANYWAY, back to the subject at hand. My vet used Ponazuril for my bunny who had hind leg weakness due to e.c.  I did see some improvement, but using Ponazuril long term can cause a lack of appetite, so it’s not something that we could use as long as other drugs.We had to take a break from it before restarting.  We also tried acupuncture and Bunny Physical therapy — where I would gently stretch and bend Bailey’s legs and massage her leg muscles to keep them from getting too stiff.   Bailey was able to do a weird hop and I had her move about a little obstacle course every day to try and keep her muscles strong, but mostly to get her brain to re-establish new pathways of getting messages to her legs. (as the E.C can damage that, causing the non-function).  All of this helped a lot.  She never fully got her gate back, but she made improvements — falling/tipping over less.  

In your case with complete paralysis, I am not sure how much permanent damage has been done — or what can be healed.  I know that one bunny at a shelter had severe head tilt for a year — but he got used to the tilt and just walked around with his head sideways — he was spunky and happy.  Someone wonderful adopted him and begin giving him neck massages and over time he made real improvement.  Again, each case is different, some do better than others and some have a hard time having the quality of life they deserve and owners are faced with tough decisions.  

There is a great resource for people who have disabled rabbits — http://www.catsandrabbitsandmore.com/disabled_rabbits

I don’t have much experience with EC other than Fenbendazole, but I just want to offer my well wishes for poor little Grover. ((((Feel Better Soon Grover)))))
