From a  distance, FDA’s October announcements look like a collection of obscure policy  actions that only a regulator would love, but taken together, they add up to a distinct  plan to crack down on some homeopathic drug products that raise health concerns.  FDA doesn’t think its past policies toward this special category of drugs are  sufficient to protect the public health.
The core  principle of homeopathy is that diluted forms of substances that cause bad  symptoms or illnesses can be used to treat people with those symptoms or  illnesses. Homeopathy has for decades been recognized by the law as an  alternative form of medicine. In fact, ever since 1938, the Federal Food, Drug  and Cosmetic Act’s very definition of what a “drug” is has explicitly included  a clause saying that any product whose active ingredients are listed in the  Homeopathic Pharmacopeia of the United States would be considered a drug on  that basis alone.  
FDA says that  lately there have been newer examples of homeopathic products that pose  significant risks. The FDA points to, for example, 99 cases of belladonna  toxicity possibly related to teething products in 2016, and over 130 reported  cases of loss of the sense of smell potentially related to an intranasal zinc  product.
FDA emphasizes  the point that that homeopathic drugs products are “subject to the same  regulatory requirements as other drugs; nothing in the FD&C Act exempts  homeopathic drug products from any of the requirements related to approval,  adulteration, or misbranding, including labeling requirements.”  
Nevertheless,  the agency has long regulated them a little differently. FDA issued its Compliance  Policy Guide about homeopathic drugs for the first time in 1988 and it was  amended over the years as the homeopathic drug industry boomed and changed, so  much so that FDA believed it necessary to list conditions under which those  products can be lawfully marketed, “including conditions regarding ingredients,  labeling, prescription status, and current good manufacturing practice.” The  conditions were designed to assure that the homeopathic drugs were promoted or  used consistently with what we might call old-fashioned homeopathy, the “recognized  or customary practice of homeopathy,” said FDA. In short, FDA’s Compliance  Policy Guide was saying that, if homeopathic drugs met the listed conditions,  FDA wouldn’t take any enforcement action against them.
Last month, completing  a process it’s been working on since 2015, the agency changed its announced  attitude. In reaction to concerns that more and more homeopathic drugs were not  promoted or used consistently with recognized or customary homeopathy , FDA  withdrew its Compliance Policy Guide altogether, and announced new guidance  that says it will take enforcement action against homeopathic drugs on a “risk-based”  basis, making a higher priority out of homeopathic products that are marketed  without FDA new drug approval if, for example, there are serious injury reports  associated with the products; or if they contain ingredients associated with  significant safety concerns such as, for example, a pathogenic infectious agent  or a controlled substance; or products that are intended to prevent or treat  serious or life-threatening diseases or conditions, among other types of  products.
                        
It’s still  only a draft guidance (Drug Products Labeled as Homeopathic, Guidance for  FDA Staff and Industry) and FDA invited public comments on it, the plan  being that the agency would take those comments into account to one degree or  another and then issue a final guidance at some point in the future. In the meantime,  the message is clear that FDA is taking a closer look at, and could start  taking more actions against, homeopathic products.
