Introduction
Once a cold sore ruptures, you may apply medication as directed by a healthcare provider to help alleviate symptoms. In daily life, avoid touching the cold sore with your hands to prevent spreading the virus to other areas or to other people. Wash your hands frequently and avoid sharing towels, cups, or other personal items to reduce the risk of viral transmission. Additionally, try to avoid factors that may trigger cold sores, such as excessive sun exposure and stress.
Generally, when a cold sore ruptures, applying medication as directed by a healthcare provider can help improve symptoms. Detailed analysis is as follows:
Cold sores are infections caused by the herpes simplex virus, characterized by blister formation around the lips. When these blisters rupture, they may cause pain, itching, and discomfort. After a cold sore breaks, antiviral creams such as acyclovir cream, penciclovir cream, or酞丁安 cream (padana cream) can typically be used according to medical advice to alleviate symptoms. Antiviral creams help reduce symptoms of viral infection, promote healing of blisters, and shorten the duration of the outbreak. Additionally, using antiviral creams helps minimize the spread of the herpes virus and reduces the risk of the cold sore spreading around the lips.
In daily life, avoid touching cold sores with hands to prevent spreading the virus to other areas or to other people. Wash hands frequently and avoid sharing towels, cups, or other personal items to reduce the likelihood of virus transmission. It is also advisable to avoid factors that may trigger cold sores, such as excessive sun exposure and stress.
