Zovirax Cold Sore Cream

Description

Zovirax Cold Sore Cream is a specialized topical antiviral medication formulated to treat and alleviate cold sores, also known as fever blisters. It is part of the antiviral medication class, specifically designed for external use on the lips and face. The active ingredient in Zovirax Cold Sore Cream is aciclovir, which has proven antiviral properties.

Cold sores are caused by the herpes simplex virus (HSV), and Zovirax Cold Sore Cream works by inhibiting the growth and spread of the virus. This results in a reduction in the severity and duration of cold sores, providing relief from the associated discomfort, itching, and burning sensations.

Zovirax Cold Sore Cream is primarily used for the treatment of cold sores but can also be applied during the early stages, known as the prodromal phase, to potentially prevent the development of a full-blown cold sore.

Directions

To ensure effective and safe use of Zovirax Cold Sore Cream, follow these step-by-step directions:
Clean Hands: Before application, wash your hands thoroughly to maintain good hygiene.
Apply Early: Start using Zovirax Cold Sore Cream at the earliest sign of a cold sore (tingling, itching, or burning sensation). The sooner you apply it, the more effective it may be.
Dosing Frequency: Apply a small amount of Zovirax Cold Sore Cream (about the size of a small pea) to the affected area on or around the lips. This is typically done five times a day, approximately every 4 hours, unless directed otherwise by a healthcare provider.
Apply with a Clean Finger or Cotton Swab: Use a clean fingertip or a cotton swab to apply the cream. Avoid using your lips to spread the cream.
Wash Hands After Application: After applying the cream, wash your hands thoroughly to prevent spreading the virus to other areas of your body.
Continue Treatment: Continue using Zovirax Cold Sore Cream for a minimum of 4 days, even if the cold sore has healed. This ensures that the virus is fully suppressed.
Always read and adhere to the instructions on the product label for specific dosing and usage guidelines.
