What to do if i cut my wrist and i don't want it to get infected do i use anti-peroxide or neosporin?

Clean: Most important thing is to adequately clean and irrigate out the laceration. Do not use hydrogen peroxide as at full strength can damage tissues. Can clean wound with 1/2 strength peroxide if necessary, anti-biotic ointment would be appropriate. Clean dressing is very important, changed daily.

Wound Care: Stop bleeding by applying pressure. Rinse wound w clean water. Clean surrounding skin w soap & water on wash cloth. Remove debris w tweezers. If material remains in wound – seek medical care. Apply antibiotic ointment. Initially cover w bandage until some healing has occurred. Change bandage when soiled/ wet or at least daily. Need tetanus shot if you haven't had one in last 10 years, don't know
