Anal fissures in children are common and frequent, and the medications used include hemorrhoid creams, such as Ma Yinglong hemorrhoid cream, tylenol ointment, and antibiotic ointments, such as gentamycin ointment or erythromycin ointment. However, since most anal fissures in children are caused by constipation, dry stools, thick and hard stool lines, and fissures in the skin of the anal canal during the process of discharge, parents should let their children eat more vegetables, fruits, cereals and other coarse fiber foods during the treatment with medication, and drink more water to deliberately help them develop good bowel habits, so as to keep the stool soft and clear to prevent constipation, so as to promote the healing of anal fissures. This will promote the healing of fissures.
