I bought a gallon of this nolvasan solution (diacetate). It only gives instructions to disenfect premises. Is it safe to use as a solution for rain rot? Also what would be the right % to dilute this? Ps I searched and searched and could not find anything.
Thank you so much in advance.

Hello Katrina,
You will find our recommendations for the proper dilutions and concentration at, Equine Diseases » Skin Diseases » Rain Rot and Rain Scald: Dermatophillus.

Hello,
Apologies for bringing this old thread back to life, but I have the same question as Katrina. I've read the information on the Dermatophillus section, and this is what you wrote:

"The affected areas are sprayed with the undiluted Betadine (10% povidone) or Nolvasan (2% chlorhexidine) solution."

I did not see anything written about dilutions. Also, I need to be sure we are talking about the Fort Dodge Nolvasan 2% chlorhexidine solution that specifically says on the container that it is not to be used on animals; only surfaces. They call it a disinfectant.

I just need to be clear that this is the same product. If so, then you recommend that, for Dermatophillus, this product can be applied full strength?

Sachet,

Nolvasan diacetate is for topical use. I don't use it full strength on skin. Dilute down to a very light blue. The Chlorhexidine S is for surface disinfecting, not animals.

Hope this helps.

Leilani, I cannot find any product called Nolvasan Diacetate SOLUTION that is other than what is used for surfaces. Can you provide me with a link to the product you (and Dr. O) use.

Does it have an "S" after the name?

Honestly Sachet, now I can't tell the difference although the Novalsan solution I use is not the "S" and I dilute it a lot; like I said to a very weak light blue before I would use it on my animals.

Hopefully Dr. O can clarify.

It IS confusing. My guess is that Nolvasan and Nolvasan S are the same except for the latter is scented (thus the reason for the S).

Both are for surfaces, according to the label and not for use on a horse's body.

That said, a friend of mine is using the non-S solution diluted at a 4-1 ration for skin fungus problems. I am reluctant to use it until I know for sure it is safe.

Hello all,

You might want to try the Fort Dodge website.

I also found several products including this one.

https://www.1800petmeds.com/Nolvasan+Skin+++Wound+Cleanser-prod2140.html

and found this one as well
https://shopping.yahoo.com/817461198-nolvasan-surgical-scrub-gallon/

I think the products for horses are not made with diacetate but with glutonate.
All the best

Thanks Rachelle, but I do not think those 'scrubs' are what Dr. O is talking about. They are soapy. I am under the assumption that the product Dr. O recommended is a 'solution' that is applied and not rinsed. Hopefully he will confirm.

This stuff used to be available in a "scrub" form and also in a diluted form for a shampoo. I have had Vets dispense the more concentrated stuff with instructions to dilute as described by Leilani. It is good stuff. There is also a nolvasan ointment that is very good.

Hello Sachet,
Yes we have used the undiluted 2% solution for dermatophilus where the skin is unbroken. As noted above you may have luck with lower percents but we seem to get the worse ones here. Human studies have suggested that even at 1% there may have been irritation (inconclusive) and certainly any animal can develop allergies. However we have not seen problems with undiluted use.

The article referenced above discusses some of the other questions above. Note well this should not be used for open wounds however. For that recommendation we use the recommendations at HorseAdvice.com » Diseases of Horses » Skin Diseases, Wounds, and Swellings » Wounds / Burns » Wounds: First Aid Care. I think this article answers most of the other questions asked above.

The one unanswered is gluconate vs acetate. As far as I can tell they should be compared on equal % of active ingredient, therefore a 4% gluconate solution is approximately twice as strong as a 2% acetate solution. I can't find this out for sure however.
