Cold Sore Treatment

Self-Care at Home

The blisters of HSV-1 contain the virus that causes cold sores. Without proper hygiene, this virus can be very contagious. This is why it is important if you have cold sores to wash your hands often, especially after you may have touched your face. Do not share cups or utensils with another person.

Medical Treatment

Because cold sores are caused by the virus herpes simplex I, there is no cure.

• In some severe cases, the doctor may prescribe a drug called acyclovir ( Zovirax), which may help shorten the length of the outbreak.
• Also, good hand washing when a sore is present will help prevent the spread of the infection and will also help prevent the sore from becoming infected with bacteria, which may make the sore last longer.
