Apply pressure with a sterile cloth or bandage and elevate your hand above your heart until the bleeding stops.
If the cut bleeds for longer than 10 minutes, or is deep enough that you can see fatty tissue, seek medical attention. Otherwise, wash your hands with soap and water, then rinse the wound with saline solution or tepid water and pat it gently with a clean cloth to dry. Apply antibiotic cream and dress the wound with a nonstick bandage. Replace the dressing daily or whenever it gets wet or dirty.
