Patients bitten by venomous snakes are usually given anti-venom, snake venom antidote; unfortunately these drugs often cause severe allergic reactions. To overcome this, there searchers suggested give adrenaline in snake bite victims before they were given anti-venom.
In a study of 1,000 people who were taken to hospital from being bitten by venomous snakes in Sri Lanka, known to those given low dose of adrenaline immediately before the given anti-venom, allergic reaction was reduced to 43 percent within an hour and fell down to 38 percent in 48 hours.
Meanwhile, patients in the control group given promethazine, hydrocortisone or placebo, did not show the same benefits.
The researchers stressed the importance of these results, especially in countries where cases of snake bite is still a common health problems and allergic reactions resulting anti-venom because most lethal.
"Currently there is no action of anti-venom manufacturer or regulations of the WHO to improve the quality of anti-venom. Until that time comes, we can show early treat with low doses of the hormone adrenaline can be effective and safe for preventing acute reactions to the anti-venom," said researchers from the University of Kelaniya, Sri Lanka.
