What should you do if a person does not have an active cold sore but is prone to them?

When dealing with a person who is prone to cold sores but does not currently have an active outbreak, the most appropriate action is to prophylactically treat them with antiviral medication. This approach helps reduce the likelihood of an outbreak occurring during or after a procedure, especially in scenarios where the skin will be exposed to potential triggering factors, such as laser treatments.

Antiviral medications work by inhibiting the replication of the herpes simplex virus, which is responsible for cold sores. Administering antiviral treatment before a procedure can help create a protective measure for individuals with a history of cold sores, helping to prevent a recurrence during a vulnerable time when skin integrity may be compromised.

While treating a person with an active cold sore may require careful consideration, and adjusting treatment settings may help mitigate risks, the proactive approach of using antivirals helps stay ahead of the potential for an outbreak. Not treating at all would leave the person vulnerable to developing sores, which can lead to complications and discomfort. Thus, prophylactic antiviral treatment is a proven strategy in cases such as this.
