Most snake bites are by nonvenomous species. Venomous snakes are found mainly in the tropics; the only species native to the UK is the adder. The effects of a venomous bite depend on the species and size of the snake, the amount of venom injected, and the age and health of the victim. A bite from an adder or other viper typically causes immediate pain and swelling at the site, followed by dizziness and nausea, a drop in blood pressure, an increase in heart-rate, and internal bleeding. Antibiotic drugs and tetanus antitoxin injections are given for all bites to prevent infection and tetanus. An injection of antivenom is also given for a venomous bite. With prompt treatment, most victims recover completely.
