After being bitten by ants, you can apply dermaplanin, also known as dexamethasone acetate cream, three or four times a day for 2 to 3 days to heal. It is important to note that if the ant bite causes a slight stinging sensation and redness and itching, you must first wash the wound with soap because alkaline soap can neutralize the ant acid secreted by the ants to stop the itching effect. The situation is not serious, you can buy your own ointment to apply, if serious, you need to go to the hospital, you need to apply ointment and oral medicine.
