Acute Cypermethrin Poisoning: Evidence‑Based Initial Management

Initial Stabilization and Assessment

Gastrointestinal Decontamination

• Routine use of activated charcoal is discouraged in cypermethrin poisoning, especially when the patient presents with altered mental status or when a considerable time has elapsed since ingestion. 1
