Stay Calm and Limit Movement
Remain as still as possible to slow venom spread. Sit or lie down, keep the bitten limb below heart level, and remove rings or tight clothing before swelling begins.
Call Emergency Services Immediately
Dial local emergency services or park rescue. Describe the location, snake description, and time of bite. If you are hiking in a remote area, use a satellite messenger or signal for help. For official guidance on venomous snakebite response, visit the American Red Cross first aid page at https://www.redcross.org/first-aid/first-aid-tips/venomous-snakebite.html.
Avoid Common Myths and Harmful Actions
Do not apply a tourniquet, ice, cut the wound, or attempt to suck out venom. Do not use electricity or herbal remedies. These methods can worsen tissue damage and delay proper medical treatment.
Get to Professional Medical Care Quickly
Antivenom is the only proven treatment for serious rattlesnake envenomation. Keep the victim still, monitor breathing, and transport to the nearest hospital or emergency clinic as fast as safely possible.
