Early treatment effect for recurrent herpes labialis
Recurrent herpes labialis is a blistering condition that occurs repeatedly around the lips. This medication quickly alleviates the initial symptoms of herpes labialis and promotes wound healing. Additionally, it helps reduce the frequency of recurrences by inhibiting viral replication. Thus, it should be used for early treatment to promptly improve symptoms.
Apply an appropriate amount that sufficiently covers the edges of the affected area 5 times daily for 5 days. Treatment should begin as soon as initial symptoms or signs appear.
This medication should not be used by individuals with certain infections, such as tuberculosis, syphilis, candidiasis, tinea, herpes zoster, chickenpox, scabies, or eczema. It should also be avoided by those who have hypersensitivity to this drug or have a history of such hypersensitivity. Patients with severely compromised immune systems, such as bone marrow transplant recipients or those with AIDS, should not use this medication. It should be avoided in patients with otitis externa who have eardrum perforations, as it may delay healing. Patients with ulcers, severe burns or frostbite, perioral dermatitis, common acne, rosacea, nursing mothers, individuals under 18 years of age, and those with a history of myocardial infarction should not use this medication. This drug should not be used on sensitive areas such as the eyes, nose, mouth, or genitals.

It is safe to refrain from breastfeeding during treatment, and it is recommended to avoid breastfeeding unless absolutely necessary. Women who are pregnant or may become pregnant must consult with a physician before using this medication, and elderly patients should be closely monitored due to a higher risk of side effects.

Particularly if using occlusive dressings, be aware that systemic side effects may occur. If used around the eyes, be cautious of the potential for increased ocular pressure or diseases such as glaucoma. The treatment duration should be limited to less than 5 days, and if symptoms do not improve or worsen, use should be stopped immediately and a specialist consulted. This medication is only for the early treatment of herpes labialis and should not be used for other skin infections or conditions.
