Treatment options for a lip allergy include rinsing with warm water and salt and taking antihistamine medications in pill or cream form to ease irritation and inflammatory reactions, states Healthline. Nonprescription pain relievers can reduce discomfort. Patients need emergency medical help if breathing becomes difficult or their lips swell suddenly.
Lip allergy patients need to maintain good oral health practices if lip bumps develop, including brushing and flossing the teeth. Picking at the affected area can slow healing time and lead to infection. If a lip infection develops, patients need to replace their toothbrushes after their infections have cleared up, according to Healthline.
