CIAV — Centro de Informação Antivenenos (poison information centre at INEM)
A telephone service run by the emergency medical service: doctors explain what to do in cases of poisoning or bites and stings — from insects, snakes or sea creatures — and whether to go to hospital. The number is 800 250 250 and calls are free.
Where you come across it. you have been stung by a wasp or hornet and are not sure whether it is dangerous; a child has drunk a household chemical; a snakebite.
This is an advice line, not an ambulance service. If the person is struggling to breathe, their face is swelling or they are losing consciousness, call 112, not this number.
