I don't understand why this article states, "In the United States, undecylenic acid is not FDA-approved for over-the-counter use for skin disorders or skin problems." Yesterday I bought, without a prescription, a product called Fungicure, whose active ingredient is undecylenic acid. Its label says it is for use on the skin of fingers and toes. The label also says, "The active ingredient in Fungicure has been recognized to be safe and effective by an FDA Expert Advisory Panel when used as directed." Thus, undecylenic acid certainly appears to have been FDA-approved for over-the-counter use for skin disorders. Can someone clarify this for me, please? 18thCHist (talk) 17:15, 11 January 2015 (UTC)

A quick search on fda.gov revealed that it is approved for use as a dandruff/seborrheic dermatitis/psoriasis treatment, BUT that there is inadequate proof of safety or effectiveness. Section 310.545 of Title 21 of Code of Federal Regulations says, "A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses..." and subsequently lists this compound to be in this category under "(7) Dandruff/seborrheic dermatitis/psoriasis drug products". It is approved, but unproven. I will leve it to others to copyedit the wiki article.

[from goodell70@yahoo.com] I am adding to this my experience with athlete's foot treatment products that contain undecylenic acid and others that do not. None of the others (it is the over-the-counter products that I refer to - such as clotrimazole, toflanate, tinactin, etc. (if I have these names right) works nearly as well as products that contain undecylenic acid. This was the primary ingredient of Desenex when for many years Desenex had a total monopoly, practically, on the treatment of Athelete's foot.  The product worked.  If it said use for four (4) weeks and if the results are unfavorable, then see a physician, it nevertheless worked, typically overnight.  The other products sometimes do not work at all, and so, yes, the athelete's foot problem will get worse and worse, and you'll need to see a physician eventually.  I am surprised and disappointed that Fungicure is the only product that is readily found on the store shelves that has this ingredient.  CVS used to make a nice 4oz tube with 30% undecylenic acid as the active ingredient, and it worked fabulously. ((I discovered this product when I had been suffering for several weeks with a severe case of athlete's foot, trying those other (somewhat expensive!) products that do not work, and I could tell within 20 minutes or so after applying it that my problems were finally solved. It was the answer to prayer.)) I am disappointed that this product is no longer on the CVS shelves. I am astounded to read that an ingredient that was used by the public, and prescribed by doctors in the Armed Forces for many years, is not being listed as FDA approved. The problem of it "stinging" when used in the crouch area is not something that is going to kill someone, though a person may wish to use a different product, or a very tiny amount of this one, for that sort of application. My main concern is that the other products do not work as well -- if, in many situations, they work at all.

Undecylenic = undecanoic?
A large section of this article discusses undecanoic acid. The page on undecanoic acid https://en.m.wikipedia.org/wiki/Undecylic_acid is very brief. I'm not an expert on these but it seems to me that Wikipedia is currently incorrectly reporting here. Twocs (talk) 12:22, 30 June 2017 (UTC) Twocs (talk) 12:22, 30 June 2017 (UTC)

Some guesses: 1. Undecenoic acid is an appropriate name for this substance. Then it should be listed in this article. 2. Undecanoic acid is different from undecenoic acid. 3. The other article may wrongly list undecanoic acid as an antifungal 4. The term undecenoic acid is common enough that it should redirect to this page Twocs (talk) 12:40, 30 June 2017 (UTC)
