• Clean Hands and Application Site: Wash your hands before and after applying the cream to prevent the spread of the virus and to avoid contaminating the cream.

• Complete the Course: Use the medication for the full course as prescribed by your healthcare provider, even if the symptoms improve before the completion of the treatment.
• Avoiding Certain Activities: It is advisable to avoid activities that may exacerbate the irritation, such as rubbing or scratching the affected area.
