Often an adder bite goes unnoticed or is confused with an insect sting until the ensuing pain gets the victim’s attention. Unfortunately, at that point, administering anti-venom may be too late. Adder venom attacks the blood and nervous system. The venom of an adder bite is less toxic than that of a puff-adder, but it is far more toxic when injected intravenously. .

Effects and Symptoms: Victims of viper bites exhibit the same symptoms as victims of cobra bites. In addition to bleeding from the gums, chills and fever, severe poisoning is indicated by swelling or haemorrhaging above the elbows or knees. These symptoms normally appear within two hours of the bite. Following a bite on the hand, the entire arm will become swollen within a half hour and skin will become purple. The victim will perspire heavily, vomit blood, and collapse within an hour. The nose and eyes bleed and loss of vision occurs, with subsequent loss of consciousness. Death, caused by cardio-respiratory arrest is inevitable if the anti-venom is not administered quickly.
