What should I do when I have itchy blisters on my lips?

The itchy blisters at the corners of the mouth are often caused by the herpes simplex virus. Antiviral drugs are required, and a light diet should be maintained to avoid all stimulating foods. When the body's immune function is particularly low, it is easy to be infected with some viruses, such as the herpes simplex virus. At this time, blisters and even itching sensations may be observed at the corners of the mouth, requiring prompt medication.

Treatment for Itchy Blisters at the Corners of the Mouth

1. Antiviral drugs: Antiviral treatment should be adopted, including oral antiviral drugs such as Aciclovir, Ganciclovir, Antiviral Oral Liquid, and Banlangen granules. Aciclovir ointment can also be applied to the affected area for local antiviral treatment.

2. Erythromycin ointment for inflammation: If the blisters at the corners of the mouth rupture and secondary infection occurs, erythromycin ointment can be applied locally for anti-inflammatory treatment.

3. Daily care: In addition, a light and digestible diet should be maintained, avoiding spicy and stimulating foods to prevent local irritation to the blisters at the corners of the mouth.

Mechanism of Itchy Blisters at the Corners of the Mouth

When the human body's immunity decreases, due to fatigue, illness, or mental stress, it is more prone to this condition. In the early stages, it manifests as local itching and burning sensations, followed by erythema and blisters. The blisters tend to cluster densely and can easily rupture, ulcerate, and exude. In severe cases, bacterial infections may occur, but usually without systemic symptoms.
