The venom of the Philippine cobra is a neurotoxin which affects cardiac and respiratory function and can cause neurotoxicity and respiratory paralysis(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. The death time of the victims is usually about several minutes in average (the fastest recorded is at some 30 seconds) after the envenomation. -Wiki
