Depends on the cause: It depends what caused your swollen lip.It can be due to allergy to meds, insect bites or foods.It can also be due to infections like cold sore or another infection and may need antibiotics.You should check with your doctor as if it is due to allergy you need to find out what caused it and may need to carry Epipen if it keeps happening as it can be life threatening.Meanwhile yu can take benadryl (diphenhydramine).
