First Aid & Emergencies

Minor animal and human bites usually can be treated at home. If you do not have an increased chance of getting an infection, do not have other injuries, and do not need evaluation by a doctor or a tetanus shot, you can clean and bandage a bite at home. Home treatment can prevent infection and promote healing.

Treat bleeding

To stop heavy bleeding, try firm, direct pressure on the wound. For more information, see how to stop bleeding .

After the bleeding has been stopped, check your symptoms to determine if and when you need to see your doctor.

Clean the wound

Clean the animal or human bite as soon as possible to reduce the chance of infection and scarring.

• Wash the wound for 5 minutes with large amounts of cool water and soap (mild dishwashing soap, such as Ivory, works well). For more information, see how to clean a bite. Some nonprescription products are available for wound cleaning that numb the area so cleaning doesn't hurt as much. Be sure to read the product label for correct use.
• Don't use rubbing alcohol, hydrogen peroxide, iodine, or Mercurochrome, which can harm the tissue and slow healing.

Some bites cause only bruising (contusions) at the bite site but do not break the skin. These bites usually do not become infected.

Stitches, staples, or skin adhesives (also called liquid skin)

Determine whether your bite needs to be treated by a doctor. Bites may need to be closed with sutures, staples, or skin adhesives so that they won't leave a large scar. Bites to the hand are not usually closed because closing the bite wound may increase your chance of having an infection. Cat bites are rarely closed because they are usually no larger than a puncture. For more information, see Are Stitches, Staples, or Skin Adhesives Necessary?

Your doctor will tell you how to take care of your stitches or staples and when to return to have them removed. Skin adhesives usually do not need to be removed, but your doctor may wish to see you to check on the wound. Be sure to carefully follow your doctor's instructions. If you are unsure of how to care for your wound or have questions, call your doctor for instructions.

Consider applying a bandage

Most bites heal well and may not need a bandage. You may need to protect the bite from dirt and irritation. Be sure to clean the bite thoroughly before bandaging it to reduce the risk of infection occurring under the bandage.

• Select the bandage carefully. There are many products available. Do not use liquid skin bandages and moisture-enhancing bandages unless your doctor tells you to. These types of dressings may seal in bacteria that could cause an infection.
• If you use a cloth-like bandage, apply a clean bandage when your bandage gets wet or soiled. If a bandage is stuck to a scab, soak it in warm water to soften the scab and make the bandage easier to remove. If available, use a nonstick dressing. There are many bandage products available. Be sure to read the product label for correct use.
• Watch for signs of infection. If an infection develops under a bandage, a visit to your doctor may be needed.
• An antibiotic ointment, such as polymyxin B sulfate (for example, Polysporin) or bacitracin, will keep the bandage from sticking to the wound. Apply the ointment lightly to the wound. Antibiotic ointments have not been shown to improve healing. Be sure to read the product label about skin sensitivity. If a skin rash or itching under the bandage develops, stop using the ointment. The rash may be caused by an allergic reaction to the ointment.
• Use an adhesive strip to hold the edges of a wound together. Always put an adhesive strip across a wound to hold the edges together, not lengthwise. You can make a butterfly bandage at home or purchase one to help hold the skin edges together.

Tetanus

• Determine whether you need a tetanus shot.
• You may have a localized reaction to a tetanus shot. Symptoms include warmth, swelling, and redness at the injection site. A fever of up to 100�F (37.8�C) may occur. Home treatment can help reduce the discomfort.
