Abstract
|
What is already known about this topic?
Administration of botulinum toxin for cosmetic reasons is considered safe in clinical settings, although it can cause transient effects near the injection site.
What is added by this report?
During March 2024, seven women experienced illness after receiving botulinum toxin injections in nonmedical settings; four were hospitalized. At least four patients had received counterfeit product.
What are the implications for public health practice?
Botulinum toxin injections should be administered by licensed and trained providers using recommended doses of Food and Drug Administration-approved products, preferably in a licensed or accredited health care setting. Clinicians who see patients with suspected botulism should immediately contact their state or local public health department.
Botulinum neurotoxin (BoNT) products are considered safe for cosmetic use when administered in clinical settings, although potential spread of BoNT around the injection site can result in local, transient neurological effects (e.g., ptosis or diplopia) (1). In March 2024, clinicians notified the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) and Tennessee Department of Health (TDH) of illnesses after presumed cosmetic BoNT injections. A multistate investigation, which included the Food and Drug Administration (FDA) and CDC, sought to characterize these illnesses and identify implicated BoNT products.
Investigation and Outcomes
Health department staff members interviewed patients and reviewed medical records to obtain information about patients' signs and symptoms, health care encounters, and exposure to BoNT products. Product information was shared with FDA. TDH Division of Laboratory Services tested patient specimens for BoNT.* This activity was reviewed by CDC, deemed not research, and conducted consistent with applicable federal law and CDC policy.†
NYC DOHMH identified three patients, and TDH identified four (including one Kentucky resident who was admitted to a Tennessee hospital). All patients were women, aged 26-55 years (median age = 48 years). Reported signs and symptoms included ptosis, dry mouth, dysphagia, shortness of breath, and weakness (Table), with onset during February 23-March 7, 2024. All patients sought health care for their illness; four were hospitalized, and two were monitored in intensive care units. None required intubation. CDC's Botulism Consultation Service determined that botulinum antitoxin was not indicated for any of the seven patients.§ All patients reported receiving cosmetic BoNT injections in nonmedical settings a median of 3 days (range = 2-20 days) before symptom onset. Serum and stool specimens collected from two patients approximately 3 weeks after symptom onset tested negative for BoNT, likely because of the interval between symptom onset and specimen collection.
The three Tennessee residents and the Kentucky resident received injections of presumed BoNT in a nonmedical residential setting from a relative of one of the recipients, who was not licensed to administer these injections. FDA determined that the BoNT product administered to those four persons was counterfeit.¶ The three NYC patients had no epidemiologic links to one another or to the Tennessee and Kentucky patients. The three NYC residents also received injections of presumed BoNT in separate nonmedical settings, with administration by an unlicensed person confirmed for one resident and suspected for two. Product information was not available; however, one person reported paying less than U.S. wholesale acquisition cost for the administered product, and another reported that the product had been purchased overseas.
Preliminary Conclusions and Actions
Seven persons experienced illness consistent with local and possible distant spread of BoNT after injection of presumed counterfeit BoNT product by unlicensed persons in nonmedical settings. Severe and potentially fatal illnesses associated with unlicensed product and off-label BoNT use have been reported (2,3). This investigation did not determine why these illnesses occurred after cosmetic BoNT injections; potential reasons might include use of counterfeit BoNT, which might be more potent or contain harmful additional ingredients or higher susceptibility to BoNT effects among some persons. Further studies are needed to describe the clinical spectrum of cosmetic BoNT injection effects (e.g., severity of signs and symptoms).
Health care providers should ask patients with symptoms of botulism about recent BoNT injections and, if botulism is suspected, immediately contact their local or state health departments.** Health departments should investigate reports of possible botulism and, if indicated, consult CDC regarding antitoxin release and notify other federal agencies to identify and remove counterfeit BoNT products from the market. BoNT injections should be administered only by licensed and trained providers using recommended doses of FDA-approved products.
