Xerese is a prescription medication that is used to treat cold sores caused by the herpes simplex virus. It is a combination of two active ingredients, acyclovir and hydrocortisone, which work together to reduce the severity and duration of cold sores.

Acyclovir is an antiviral medication that works by stopping the growth and spread of the herpes virus. It helps to speed up the healing process and reduce the risk of complications from cold sores. Hydrocortisone is a corticosteroid that helps to reduce inflammation and itching associated with cold sores.

Xerese comes in the form of a cream that is applied directly to the affected area. It is important to follow the instructions provided by your healthcare provider and use the medication as directed. Typically, Xerese is applied five times a day for five days at the first sign of a cold sore.

Like all medications, Xerese may cause side effects in some individuals. Common side effects may include mild burning or stinging at the application site. If you experience any severe or persistent side effects, it is important to contact your healthcare provider.

It is important to note that Xerese is not a cure for cold sores or the herpes virus. It is intended to help manage symptoms and reduce the frequency of outbreaks. It is also important to practice good hygiene and avoid close contact with others while you have an active cold sore to prevent spreading the virus.

If you have any questions or concerns about Xerese or its use, do not hesitate to speak with your healthcare provider. They can provide you with more information and guidance on how to best manage your cold sores.
