Why is this medication prescribed?

Acyclovir topical is prescribed to treat viral infections of the skin caused by the herpes simplex virus. It is commonly used to treat:

• Cold Sores (Herpes Labialis): Acyclovir topical can help reduce the symptoms and duration of cold sores on the lips or face.
• Genital Herpes: Acyclovir topical can be applied to treat outbreaks of genital herpes and help reduce the severity and healing time of sores.
• Shingles (Herpes Zoster): In some cases, it might be used to alleviate the pain and discomfort associated with shingles.

The medication works by inhibiting the replication of the herpes virus, which helps to slow the spread of the infection and allows the immune system to fight it off more effectively. It does not cure herpes but can reduce the severity and frequency of outbreaks.

How should this medicine be used?

Acyclovir topical should be used according to your healthcare provider’s instructions. Here are general guidelines for its use:

• Apply as Soon as Symptoms Appear: For the best results, apply Acyclovir topical as soon as you notice the first signs of a herpes outbreak, such as tingling, redness, or itching.
• Clean and Dry the Affected Area: Before applying the medication, wash the affected area with soap and water, and gently pat it dry with a clean towel.
• Apply a Thin Layer: Using a clean finger or a cotton swab, apply a thin layer of the cream or ointment to the affected area. Make sure to cover all sores or blisters.
• Wash Your Hands: After applying the medication, wash your hands thoroughly to avoid spreading the infection to other parts of your body or to other people.
• Dosage Frequency: Typically, Acyclovir topical is applied 5 times a day (about every 3 to 4 hours while awake) for 4 days for cold sores. The frequency and duration may vary depending on your healthcare provider’s instructions.
• Avoid Contact with Eyes: Do not apply the medication near or in your eyes, and avoid touching your eyes after applying it. If it accidentally gets into your eyes, rinse thoroughly with water.
• Do Not Cover with Bandages: Avoid covering the treated area with bandages or dressings unless directed by your healthcare provider.
• Avoid Touching or Scratching: To prevent further irritation or spread of the virus, try not to touch or scratch the sores.
• Complete the Full Course: Use the medication for the full prescribed period, even if symptoms improve before the treatment is finished.

If you have any specific questions or concerns about how to use Acyclovir topical, it’s best to consult your healthcare provider.

Other uses for this medicine

• Herpes Zoster (Shingles): Although not a primary treatment, Acyclovir topical may sometimes be used to help alleviate skin symptoms associated with shingles.
