Introduction

If lip corner blisters are caused by bacterial infections, such as streptococcal or staphylococcal infections, using erythromycin ointment can help inhibit bacterial growth and promote wound healing. Erythromycin ointment may also be used as directed by a physician for angular cheilitis. However, if the blisters around the mouth are caused by a herpes simplex virus infection, erythromycin ointment is not the treatment of choice.

Generally speaking, if blisters appear at the corners of the mouth, erythromycin ointment may be used if they are caused by bacterial infection. However, if the blisters are caused by other factors, this medication is not recommended. It is advisable to visit a hospital to determine the underlying cause and follow medical instructions for treatment. The analysis is as follows:

If the blisters at the corners of the mouth are caused by bacterial infections, such as streptococcus or staphylococcus infections, using erythromycin ointment can help inhibit bacterial growth and promote wound healing. If angular cheilitis occurs, erythromycin ointment may also be used under medical guidance. Angular cheilitis is sometimes caused by bacterial infection when the corners of the mouth are dry and cracked. In such cases, erythromycin ointment can serve as an adjunctive treatment to help reduce inflammation and promote tissue repair.

If the blisters at the corners of the mouth are caused by herpes simplex virus infection, erythromycin ointment is not the first-line treatment. In this case, antiviral ointments such as valacyclovir hydrochloride tablets, acyclovir cream, or penciclovir cream should be used to suppress viral replication and promote healing of the blisters. If the blisters are caused by an allergic reaction to a contact allergen, erythromycin ointment will not directly address the issue. In such cases, exposure to the allergen should be avoided.

During the application of any ointment, it is important to maintain cleanliness and dryness in the affected area. Scratching or squeezing the blisters with hands should be avoided to prevent infection or worsening of symptoms.
