Eleven days after circumcision, if the wound is observed to have healed and recovered, there is usually no need to change the medication, and you will need to follow your doctor’s instructions as to whether or not you need to change the medication. After circumcision, you usually need to change the medicine regularly, about a week’s time, in order to prevent bacteria from attacking the wound and causing infection. If the wound shows more secretions such as oozing fluid and blood, localized redness and swelling, etc., it is necessary to change the medicine in time to prevent infection, which is not conducive to the recovery of the wound. If the patient observes that there is no occurrence of the above mentioned situations, the doctor indicates that the wound has basically healed and recovered, so there is no need to change the medicine. After the operation, patients should pay attention to a light diet, reduce the stimulation of the affected area, and try to avoid erection, in order to prevent infection or wound cracking, which is not conducive to recovery.
