When injuries and illnesses are not life-threatening, first-aid kits and supplies can provide relief. To prevent contamination, wounds are covered with bandages, gauze, pads, and wraps. Ice packs and thermal wraps can be used to relieve muscle and joint pain. First-aid tape is used to secure bandages and wound dressings. First-aid kits contain medical supplies for treating minor injuries such as cuts, insect bites, and burns. A variety of nonprescription medications are available for treating headaches, aches, pains, coughs, colds, and upset stomachs. Topical ointments, creams, and antiseptics are used to treat pain, stings, and rashes.
