Drop by drop, the Northern Philippine Cobra has the most potent venom of all the species in the genus Naja. The venom is mainly composed of neurotoxins. The postsynaptic neurotoxins interrupt the transmission of nerve signals by binding to the neuro-muscular junctions near the muscles. The symptoms might include headache, nausea, vomiting, abdominal pain, diarrhoea, dizzyness, collapse, convulsions.
Particularly in children, collapse and convulsions may be the first evidence of envenoming, at least for certain species. It is often assumed that hypotension will occur in response to envenoming, but hypertension is also common and both tachycardia and bradycardia are reported. Complete respiratory failure leads to victim's death.
