Drug Overview

Docosanol Cream, 10% is a non-prescription medication designed to help treat cold sores and fever blisters on the face or lips. It works by shortening the healing time and reducing the duration of symptoms such as tingling, pain, burning, and itching associated with these outbreaks.

This topical cream is similar to the active ingredient found in Abreva® and is intended for external use only. If you're looking for relief from cold sore symptoms, Docosanol Cream may be a helpful option to consider.

Uses

If you’re dealing with cold sores or fever blisters on your face or lips, this medication can help. It not only treats these uncomfortable sores but also shortens the healing time and reduces the duration of symptoms like tingling, pain, burning, and itching.

When you notice the first signs of a cold sore or fever blister, such as a tingling sensation, apply the cream directly to the affected area on your face or lips.

For adults and children aged 12 years and older, you should apply the cream five times a day until the cold sore is healed. If you are considering using this cream for a child under 12, it’s best to consult a doctor first for guidance. Remember to wash your hands again after applying the cream to avoid spreading the virus.
