The most effective at-home treatment for diaper rash is to keep the affected infant's skin as clean and dry as possible, according to Mayo Clinic. The use of over-the-counter ointments and increasing airflow around the diaper region are also effective in getting rid of diaper rash.
Diaper rash is a common skin inflammation typically caused by constantly wet diapers or diarrhea. It can also be caused by friction from a tight-fitting diaper and harsh detergents and soaps on sensitive skin, according to Kid's Health. Diaper rash can appear on the baby's bottom, genitals or upper thighs.
Frequently changing a baby's diaper is the best way to keep the diaper area clean and dry. Over-the-counter ointments and creams are widely available to help treat diaper rash. The best choices are diaper rash products with zinc oxide as the active ingredient, as it both soothes and protects the area from moisture. A doctor can help determine whether an ointment or a cream is best, depending on the particular rash.
To increase air flow to the affected area, the infant should go without a diaper for short amounts of time and larger-sized diapers should be used until the rash is gone. It's best to avoid plastic diaper covers, as they trap moisture in and prevent any air flow to the diaper region.
