Description
Indications
This medication combines two active ingredients: acyclovir and hydrocortisone. It is primarily used to treat cold sores or fever blisters caused by the herpes simplex virus. Acyclovir, an antiviral medication, works by inhibiting the growth of the virus. Hydrocortisone, a corticosteroid, aids in relieving symptoms such as itching, pain, and burning.
Uses and Dosage
To use this medication effectively, apply it at the first sign of a cold sore outbreak. Before and after application, wash your hands thoroughly with soap and water. Ensure the affected area is clean and dry before applying the medication.
Follow your doctor’s instructions and apply a thin layer of the cream on the affected area, typically 5 times a day (every 3 to 4 hours) for a duration of 5 days. Apply enough cream to cover all affected areas, but avoid rubbing the area to prevent spreading to other areas around your mouth or exacerbating the cold sore.
Refrain from using other skin products, including makeup, sunscreen, or lip balm, and avoid covering the affected area with a bandage.
To ensure the medication stays in place, refrain from bathing, showering, or swimming for at least 30 minutes after application. Do not apply this medication in the eyes or nose, inside the mouth, or on the genitals.
Remember that cold sores caused by herpes can easily spread. While acyclovir/hydrocortisone cream can help alleviate symptoms, it does not prevent the spread of herpes. Avoid sharing eating utensils, cups, razors, or towels during an outbreak. Additionally, try to refrain from touching the cold sore, including kissing, and wash your hands if you inadvertently touch it.
Consistent use of this product is essential to derive the maximum benefit. If your condition persists or worsens after 2 weeks, inform your doctor promptly.
