If you are bitten by a common spider at home, you need to wash the wound immediately, disinfect it, apply ice, and then apply or take medication under a doctor’s supervision. If you are bitten by a common spider at home, you need to rinse the bite site as soon as possible with a lot of soapy water or soda, which can play a role in neutralizing the venom, and then rinse off the soapy residue with water. Then, use iodophor or alcohol to disinfect the bite twice from the inside out to avoid infection of the wound. After that, use a towel wrapped in an ice pack to apply ice to the wound to relieve swelling and other discomforts. It is important to note that the ice pack should not come into direct contact with the skin. After the above steps, patients are advised to go to the hospital and choose the appropriate medication according to the severity of the symptoms. If the injured person has severe localized pain, he or she can take painkillers such as acetaminophen as prescribed by the doctor. If the bite is mild, anti-inflammatory medications such as topical hydrocortisone ointment can be applied. For more severe symptoms, medications such as cetirizine may also be prescribed for relief. Bites from common household spiders should be treated immediately and medical attention should be sought. Sucking venom from the bite wound with your mouth is prohibited.
