If you believe that you have been bitten by a dangerous spider, like a black widow or brown recluse, seek medical attention right away.
Home Remedies
To treat a venomous spider bite at home, wash the area well and then apply ice. The ice will help to slow your body’s absorption of the spider’s venom. Elevate the limb or area of the body that was bitten and try to remain still. Then seek medical treatment.
Medical Treatment
When you seek medical care for a possibly venomous spider bite, your healthcare provider will start by inspecting the bite mark. There is no way to test for a spider bite. Your practitioner may diagnose one based on an examination of the wound.
Once it is determined that your bite requires treatment, the healthcare provider will discuss a plan with you. Treatment for spider bites typically involves addressing the symptoms as they occur. If you have a heart condition, your healthcare provider may recommend admitting you to the hospital for observation and treatment.
