K-Y Lubricating Jelly (Van Horn and Sawtell, New York), originally advertised as a lubricant for instruments and the hands, is now also recommended as a therapeutic agent. If the claims for “K-Y” were limited strictly to such effects as result from the purely mechanical properties of a lubricant, it might be held that it would not come under the purview of the Council. The preparation, however, while introduced as a lubricant, is now offered for a broader field of use, and the manufacturers make claims which are not supported by any evidence available to the Council. Evidence the following, taken from a circular that accompanies the package: “K-Y allays smarting and burning at once through its pronounced soothing and cooling effects, and thus makes an admirable dressing for burns.” “Many physicians make a practice of anointing the bodies of their measle and scarlet fever patients with ‘K-Y,’ in this way affording gratifying relief from itching and irritation, and effectively preventing dissemination of infectious material.” And this from another circular: “I had one of the most troublesome cases of pruritus vulvæ that I had ever seen. I guess I must have tried everything and the case had been referred to me by another man, who had previously tried everything, including cauterization. Well, one day I was examining her, and of course K-Y on the speculum--the irritation seemed to quiet down, and the following day she said she felt no effects from it at all. Then later on, it returned, and I couldn’t imagine what had done so much good, unless it could have been the lubricant, so I told her to buy a tube, which she did. Every once in a while she has a return of it slightly, but she just applies K-Y and clears it all up.” The manufacturers state that they do not know why K-Y is so soothing, but suggest: “Possibly the cooling action of the combination, and the effect of the 4% boric acid contained, are factors that enter. Be all that as it may, the fact certainly remains that oftentimes, after other local measures fail, ‘K-Y’ lubricating Jelly gives relief.” Elsewhere it is claimed to be germicidal, and to give relief in other conditions, thus: “Diabetic and uremic irritations, not only of the genitalia, but of other parts, have been found fully as amenable as pruritus vulvae to the soothing influence of ‘K-Y’ Lubricating Jelly, especially if the previous application is removed with water every time a new one is put on.”
