[Code of Federal Regulations] [Title 21, Volume 4] [Revised as of April 1, 2008] From the U.S. Government Printing Office via GPO Access [CITE: 21CFR250.108] [Page 178-179] TITLE 21--FOOD AND DRUGS CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES (CONTINUED) PART 250_SPECIAL REQUIREMENTS FOR SPECIFIC HUMAN DRUGS--Table of Contents Subpart B_New Drug or Prescription Status of Specific Drugs Sec. 250.108 Potassium permanganate preparations as prescription drugs. (a) There have been a number of reports in the medical literature of serious injuries to women resulting from the misuse of potassium permanganate in an effort to induce abortion. Reports from physicians who have treated such cases show that the injuries are commonly caused by introducing tablets or crystals of potassium permanganate into the vagina. Experience with these cases shows that such use of potassium permanganate is not effective in producing abortion, but that instead the drug produces serious and painful injury to the walls of the vagina, causing ulcers, massive hemorrhage, and infection. Such dangerous and useless employment of potassium permanganate is apparently encouraged among the misinformed by the mistaken idea that the vaginal bleeding caused by the corrosive action of the drug indicates a termination of pregnancy, which it does not. (b) Potassium permanganate is a strong oxidizing agent, a highly caustic, tissue-destroying chemical, and a poison. There are no circumstances under which crystals and tablets of potassium permanganate constitute safe dosage forms for use in self-medication. It is the consensus of informed medical opinion that the only dosage forms of potassium permanganate known to be safe for use in self-medication are aqueous solutions containing not more than 0.04 percent potassium permanganate. Such solutions are safe for use in self-medication only by external application to the skin. (c) In view of the very real potentiality for harmful effect, and the actual injuries caused by the misuse of potassium permanganate, the Food and Drug Administration believes that in order adequately to protect the public health: (1) Potassium permanganate and potassium permanganate tablets intended for human use are drugs subject to section 503(b)(1) of the Federal Food, Drug, and Cosmetic Act and should be restricted to prescription sale. Such drugs will be regarded as misbranded if at any time prior to dispensing the label fails to bear the statement ``Rx only.'' (2) Potassium permanganate labeled for use as a prescription component in human drugs under the exemption provided in Sec. 201.120 of this chapter or labeled for manufacturing use under the exemption provided in Sec. 201.122 of this chapter will be regarded as misbranded unless the label bears the statement, ``Rx only.'' (3) These drugs will be regarded as misbranded when intended for veterinary use unless the label bears the legend, ``Caution: Federal law restricts this drug to sale by or on the order of a licensed veterinarian''; Provided, however, That this shall not apply to a drug labeled and marketed for veterinary use if such drug contains not more than 50 percent of potassium permanganate and includes other ingredients which make it unsuitable for human use and unlikely that the article would be used in an attempt to induce abortion. (4) Any preparation of potassium permanganate intended for over-the- [[Page 179]] counter sale for human use internally or by application to any mucous membranes or for use in the vagina will be regarded as misbranded under the provisions of section 502(f) (1) and (2) and section 502(j) of the act. (5) Any other preparation of potassium permanganate intended for over-the-counter sale for human use will be regarded as misbranded under section 502(f) (1) and (2) and section 502(j) of the act unless, among other things, all of the following conditions are met: (i) It is an aqueous solution containing not more than 0.04 percent potassium permanganate. (ii) The label and labeling bear, in juxtaposition with adequate directions for use, clear warning statements designated as ``Warning,'' and to the effect: ``Warning--For external use on the skin only. Severe injury may result from use internally or as a douche. Avoid contact with mucous membranes.'' (d) The labeling or dispensing of any potassium permanganate preparations intended for drug use within the jurisdiction of the Federal Food, Drug, and Cosmetic Act contrary to this statement after 60 days from the date of its publication in the Federal Register may be made the subject of regulatory proceedings.
