AddressedDear Dr. Reisacher

1Introduction

1 paragraph

The United States Food and Drug Administration (FDA) reviewed your brochure at https://ent.weill.cornell.edu/sites/default/files/lifewithoutallergies.pdf (last visited September 2025), which describes Allerdent, an allergenic toothpaste, which you state “can be sent directly to your home,” (hereafter, “your product”).1 This letter is to advise you that your product is an unapproved new drug in violation of section 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. § 355(a). Your product is also an unlicensed biological product in violation of section 351(a)(1) of the Public Health Service Act (PHS Act), 42 U.S.C. § 262(a)(1). A biological product for which a biologics license application (BLA) has been approved under section 351(a) of the PHS Act is not required to have an approved application under section 505 of the FD&C Act, 21 U.S.C. § 355; 42 U.S.C. § 262(j). Otherwise, with certain exceptions not applicable here, a new drug may not be introduced or delivered for introduction into interstate commerce without an approved application from FDA in effect, as described in section 505(a) of the FD&C Act. The introduction or delivery for introduction of your product into interstate commerce, or the causing thereof, is prohibited under section 301(d) of the FD&C Act, 21 U.S.C. § 331(d).

2Unapproved New Drug and Unlicensed Biological Product Violations

3 paragraphs

Based on information reviewed by FDA, https://ent.weill.cornell.edu/sites/default/files/lifewithoutallergies.pdf (last visited September 2025), your product is intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease or conditions in humans and/or is intended to affect the structure or function of the body. For example, your brochure states, “With Allerdent you can experience allergy immunotherapy while simply brushing your teeth every day. This is known as oral mucosal immunotherapy, or OMIT”.

Therefore, your product is a drug as defined in section 201(g)(1) of the FD&C Act, 21 U.S.C. § 321(g)(1), and a biological product as defined in section 351(i) of the PHS Act, 42 U.S.C. § 262(i).

Subject to certain exceptions not applicable here, to lawfully introduce or deliver for introduction into interstate commerce a drug that is a biological product, a valid BLA must be in effect under section 351(a)(1) of the PHS Act, 42 U.S.C. § 262(a)(1). Such licenses are issued only after showing that the product is safe, pure, and potent. Your product is not the subject of an approved BLA.
