In August 2021, the Centers for Disease Control and Prevention (CDC) released a health alert following the rapid increase in ivermectin prescriptions and reports of severe illness associated with use of products containing ivermectin for the prevention or treatment of COVID-19 infections. The United States Food and Drug Administration (FDA) and the CDC have explicitly discouraged the use of ivermectin in the prevention or treatment of COVID-19 outside of clinical trials. The study aims to describe the adverse events (AEs) related to ivermectin use for the prevention or treatment of COVID-19.This is a prospective case series of adverse events related to therapeutics used in the prevention or treatment of COVID-19 submitted to the FDA ACMT COVID-19 ToxIC (FACT) Pharmacovigilance Project sub-registry between October 2020 and December 2021. This is an ongoing toxico-surveillance system at 15 major academic medical centers in 12 states. Data collected included sociodemographics, exposure related information including dose, frequency, route, duration, and reason for taking ivermectin as well as a clinical description of the adverse event and the outcome.A total of 40 patients who developed AEs following ivermectin use were reported to FACT over 15 months. Self-medication with veterinary formulations were reported in 18/40 patients Thirty-three patients presented to emergency departments and nineteen patients were admitted to the hospital. Patients reported using ivermectin for prevention (24/40), treatment of symptoms (19/40), and for treatment of documented COVID-19 (8/40). Neurological toxicity was the most frequent finding. Fifteen patients had minor symptoms while 25 developed severe toxicity.Ivermectin use for the attempted treatment of COVID-19 has potential adverse health effects primarily related to neurological function. This is especially true when patients are self-treating with this medication and when they are using formulations intended for non-human use.

The Toxicology Investigators Consortium (ToxIC) Core Registry was established by the American College of Medical Toxicology in 2010. The Core Registry collects data from participating sites with the agreement that all bedside and telehealth medical toxicology consultations will be entered. This twelfth annual report summarizes the registry's 2021 data and activity with its additional 8552 cases. Cases were identified for inclusion in this report by a query of the ToxIC database for any case entered from January 1 to December 31, 2021. Detailed data was collected from these cases and aggregated to provide information, which included demographics, reason for medical toxicology evaluation, agent and agent class, clinical signs and symptoms, treatments and antidotes administered, mortality, and whether life support was withdrawn. Gender distribution included 50.4% of cases in females, 48.2% of cases in males, and 1.4% of cases in transgender or gender non-conforming individuals. Non-opioid analgesics were the most commonly reported agent class (14.9%), followed by opioids (13.1%). Acetaminophen was the most common agent reported. Fentanyl was the most common opioid reported and was responsible for the greatest number of fatalities. There were 120 fatalities, comprising 1.4% of all cases. Major trends in demographics and exposure characteristics remained similar to past years' reports. Sub-analyses were conducted to describe new demographic characteristics, including marital status, housing status and military service, the continued COVID-19 pandemic and related toxicologic exposures, and novel substances of exposure.

Novel opioids in the illicit drug supply, such as the "nitazene" group of synthetic opioids, present an ongoing public health problem due to high potency and respiratory depressant effects. We describe three patients in whomThis is a case series of patients with acute opioid overdose enrolled in an ongoing multicenter prospective cohort study. Data collected included reported substance use, clinical course, naloxone dose and response, outcome, and analytes detected in biological samples.Between October 6, 2020 and October 31, 2021, 1006 patients were screened and 412 met inclusion criteria. Of these, three patients (age 33-55) tested positive forThese cases represent a local outbreak of a novel "nitazene" opioid. Public health toxicosurveillance should incorporate routine testing of this emerging class of synthetic compounds in the illicit drug supply.

Exposure to single-use detergent sacs (SUDS), or laundry pods, have declined in the pediatric population between 2015 and 2018. Older adult exposures are less well described, and it is unclear if there is an increased risk of unintentional exposure to SUDS in older adults, especially in those with dementia. This study aims to review SUDS exposures in adults greater than 60-year-old between 2012 and 2020.Using the National Poison Data System (NPDS), a query was performed for cases involving an acute single substance exposure with substance coded as "laundry detergent unit dose" (Generic code: 0201181, 0201182, and 0201183) in adults greater than 60-years-old between January 1, 2012 and December 31, 2020. Exclusion criteria included unknown age, age less than 60 years, any multi-substance exposure, and chronic or acute-on-chronic acuity. The distribution of cases was analyzed for demographics, exposure circumstances, management, clinical effects, and medical outcome.SUDS exposure reported to NPDS increased from 46 cases in 2012 to 219 cases in 2020. Among the 1289 total reported cases, 94.9% (Despite a declining incidence of pediatric SUDS exposure, older adult exposures have increased over 400% between 2012 and 2020.
