When patients suffer from allergic cheilitis, it is crucial to identify the specific allergen. Generally, patients do not need to panic in such cases. For mild allergic cheilitis, it usually suffices to avoid using or contacting the allergen, enabling the condition to heal. If the cheilitis is severe and causes significant redness and swelling, it may also be appropriate to use some anti-allergy ointments, which can effectively alleviate the discomfort caused by the allergies. Additionally, patients should pay attention to their diet by eating lightly and avoiding spicy or irritating foods. It is also beneficial to drink plenty of water, get adequate rest, avoid staying up late, and enhance body resistance, which can also help mitigate some inflammatory irritations.
