Washington D.C. - February 18th, 2026 - The U.S. Food and Drug Administration (FDA) announced today that it is undertaking a comprehensive reassessment of the safety profile of over-the-counter (OTC) lice treatments containing permethrin. This action follows a notable increase in reported adverse reactions, ranging from localized skin irritation to severe systemic effects like allergic reactions and respiratory distress. The FDA's move signals a growing concern over the widespread use of this common pediatric treatment and is prompting calls for increased awareness among parents, caregivers, and healthcare professionals.

For decades, permethrin has been a go-to solution for eradicating head lice, a common parasitic infestation particularly affecting school-aged children. However, recent data submitted through the FDA's MedWatch adverse event reporting system reveals a concerning trend. While the total number of lice infestations remains relatively stable, the frequency of reported complications following permethrin treatment is demonstrably rising. The FDA's initial investigation indicates the reactions are not limited to a specific age group or formulation, raising questions about potential manufacturing inconsistencies, increasing resistance within lice populations, or previously underreported sensitivities.

The Nature of the Adverse Reactions

The reported adverse reactions are diverse in severity. Mild cases typically involve localized redness, itching, and burning at the application site. However, the FDA is particularly concerned with the growing number of reports detailing more serious symptoms. These include widespread hives, facial swelling, difficulty breathing, and even anaphylactic shock - a life-threatening allergic reaction. Several reports detail the need for emergency medical intervention, including epinephrine administration and hospitalization.

Dr. Eleanor Vance, a leading pediatric dermatologist consulted by this publication, explained, "While allergic reactions to permethrin aren't entirely new, the increase in their frequency, and the reported severity, warrants careful investigation. We're also seeing anecdotal evidence suggesting that prolonged or repeated use of permethrin may be contributing to increased skin sensitivity, making subsequent treatments more problematic."

What the FDA is Doing - and What You Should Do The FDA's reassessment includes a thorough review of existing clinical data, manufacturing processes, and post-market surveillance reports. The agency is also actively collaborating with the Centers for Disease Control and Prevention (CDC) to monitor lice resistance patterns and assess the effectiveness of alternative treatment options. The review is expected to be completed within the next six to nine months, with potential outcomes ranging from revised product labeling to voluntary recalls or even the removal of certain permethrin-based products from the market.

In the meantime, the FDA is urging parents and caregivers to take the following steps:

• Report Adverse Reactions: Prompt reporting of any suspected adverse reaction following permethrin use is crucial. The FDA's MedWatch online reporting system ([ https://www.fda.gov/safety/medwatch ]) provides a straightforward platform for submitting these reports.
• Explore Alternative Treatments: The FDA recommends considering non-chemical methods or alternative active ingredients. Effective alternatives include:
  • Wet Combing: This labor-intensive method involves meticulously removing lice and nits (lice eggs) from wet hair using a fine-toothed comb. It requires multiple sessions but avoids chemical exposure.
  • Lice Treatments with Different Active Ingredients: Products containing pyrethrins, benzyl alcohol, or other approved insecticides offer alternative mechanisms of action. However, it's important to be aware that cross-resistance can sometimes occur.
  • Professional Treatment: Consult a healthcare professional for guidance and potential prescription-strength treatments.
• Strictly Follow Label Instructions: Always read and carefully follow the instructions provided on the product label. Do not exceed the recommended dosage or application time.
• Consult a Healthcare Professional: Before using any medicated lice treatment on a child, especially those with pre-existing skin conditions or allergies, consult with a pediatrician or dermatologist.

The Broader Implications

This situation highlights a broader concern regarding the safety of widely available OTC medications. While convenient, these products often undergo less rigorous scrutiny than prescription drugs. The FDA's response to the permethrin issue serves as a reminder that even established treatments can pose unforeseen risks and that ongoing vigilance is essential to protect public health. It also underscores the growing issue of insecticide resistance in parasitic populations, a problem that demands continued research and the development of innovative treatment strategies. The agency expects to release a public statement with findings and recommendations once the review is complete.
