FDA Cites Ketamine Store / www.ketaminestore.org in 2026-06-23 Warning Letter — Unapproved New Drugs/Misbranded
Letter issued · posted to fda.gov .
Subject as published: Unapproved New Drugs/Misbranded
TL;DR
At a glance: The FDA Center for Drug Evaluation and Research issued a warning letter (MARCS-CMS 725147, June 23, 2026) to Ketamine Store / www.ketaminestore.org for introducing unapproved and misbranded ketamine drug products into interstate commerce in violation of the Federal Food, Drug, and Cosmetic Act (sections 301(a), 301(d), 301(k), 502(f)(1), 503(b)(1), and 505(a)). The FDA identified products including "KETAMINE LIQUID" marketed with disease-treatment claims, noting that while FDA-approved ketamine formulations exist (e.g., KETALAR, a Schedule III controlled substance available by prescription), the company's offerings lack required drug applications and pose safety risks including contamination, counterfeit ingredients, and serious adverse events, particularly from unapproved injectable products used without medical supervision. The FDA requested the entity cease offering these unapproved and misbranded drugs and warned that failure to address violations may result in seizure and injunction.

# FDA Warning Letter Analysis: Ketamine Store
**Company and Violations**
The FDA's Center for Drug Evaluation and Research issued a warning letter to Ketamine Store (www.ketaminestore.org) on June 23, 2026, for introducing unapproved and misbranded ketamine products into interstate commerce. The agency conducted a website review on February 26, 2026, and documented significant violations related to the sale of ketamine formulations marketed for psychiatric and pain management without FDA approval. The FDA identified specific products including "Ketamine Liquid," "Ketamine Troches," and "Ketamine Nasal Spray" being offered directly to consumers.
**Regulatory Citations and Implications**
The violations cite sections 301(a), 301(d), 301(k), 502(f)(1), 503(b)(1), and 505(a) of the Federal Food, Drug, and Cosmetic Act. Section 505(a) requires FDA approval before marketing new drugs; sections 301(d) and 301(k) address illegal introduction of drugs into interstate commerce; section 502(f)(1) concerns proper labeling with adequate directions for use. The company failed to meet exemption conditions under sections 503A and 503B, which govern compounded drugs. The FDA emphasized that while FDA-approved ketamine exists (KETALAR, a Schedule III injectable for anesthesia), and esketamine exists (SPRAVATO nasal spray with a black box warning for treatment-resistant depression), the products sold by Ketamine Store lack required approvals, REMS compliance, and medical supervision safeguards.
**Timeline and Industry Implications**
Companies in this sector should monitor for enforcement actions within 30 days. Compliance officers typically watch for seizure actions, injunctions, or criminal referrals if the company fails to cease operations. Peer organizations should review their own product claims, verify compounding eligibility under 503A/503B conditions, and ensure proper prescription requirements and supervision protocols. The letter signals heightened FDA scrutiny of internet-based ketamine sales outside established medical frameworks.
Severity context
Critical severity. Typically reserved for data integrity, sterile-product CGMP, or repeat violations — matters that historically precede injunctions, consent decrees, or import alerts.
Regulatory background
Unapproved-drug letters cite 21 USC 355 (NDA requirement) or 21 USC 331(d) (introduction into interstate commerce). FDA increasingly applies these provisions to homeopathic products, kratom, and certain compounded preparations.
What peer compliance teams typically do next
Most compliance officers at peer companies use a Warning Letter against a named entity as a checklist for their own CAPA program. Common steps: pull the verbatim FDA letter; map each cited 21 CFR section against the team’s SOP library; confirm CAPA coverage; brief the QMR (Quality Management Review) on whether the cited subject matter is in scope for the next internal audit. The 15-business-day response window applies to the cited entity, not to peers — but a documented internal review against the cited subjects is what regulators expect to see if a peer is later inspected on the same topic.

Promptly address the violations described herein without delay, including ensuring that appropriate resources are allocated to fully address the violations and prevent their recurrence. This is not intended to be an all-inclusive list of the violations that may exist in connection with your products or operations. It is your responsibility to ensure that you comply with all requirements of federal law, including FDA regulations. Failure to adequately address violations may result in regulatory or legal action without further notice including, without limitation, seizure and injunction. As discussed below, FDA has observed that www.ketaminestore.org introduces into interstate commerce unapproved and misbranded ketamine drug products, including certain drugs for which the FDA-approved version is an injectable or subject to a Risk Evaluation and Mitigation Strategy (REMS). 1 FDA has identified significant risks associated with unapproved ketamine products, especially in the absence of appropriate medical supervision. Given the increased interest in the use of ketamine products, the easy availability of unapproved and misbranded ketamine products via the internet puts U.S. consumers at risk for serious adverse events. Furthermore, injectable drug products can pose a serious risk of harm to users because they bypass many of the body's natural defenses against toxic ingredients, toxins, or dangerous organisms that can lead to serious and life-threatening conditions such as septicemia or sepsis. There are also inherent risks to consumers who purchase unapproved new drugs and misbranded drugs. Unapproved new drugs do not carry the same assurances of safety and effectiveness as those drugs subject to FDA oversight. Drugs that have circumvented regulatory safeguards may be contaminated, counterfeit, contain varying amounts of active ingredients, or contain different ingredients altogether. Accordingly, FDA requests that www.ketaminestore.org cease offering any unapproved and misbranded drugs for sale to U.S. consumers. This is critical to shielding the American public from harm. FDA Review Violations were identified and documented during a review of your website www.ketaminestore.org, FDA Establishment Identifier (FEI) 3043544014, on February 26, 2026.
