“Lakshmanrekha” also known as an insecticide is a combination of Cypermethrin and Deltamethrin. Both are pyrethroid compound and is widely used due to its high insecticidal potential and slow resistance in pest. It is considered less toxic for human use, because of poor dermal absorption, rapid metabolism, less tissue accumulation, and environmental persistence. Cases of accidental pyrethroid poisoning at work places have been reported, but poisoning with suicidal intention is extremely rare. We report a case of 33-year old female who presented to our emergency department with complaints of recurrent vomiting, epigastric and throat pain, increased salivation, drooling, lacrimation, anxiety after ingestion of Lakshmanrekha. There was no history of convulsion, diarrhea, frequent urination, chest pain, or fever.
