Ointments for cold sores have antiviral substances in their composition, such as acyclovir or penciclovir, which help to eliminate the herpes simplex virus, facilitating the healing of blisters, preventing the formation of new sores, decreasing itching and relieving the pain. In this way, the ointments accelerate the recovery of mouth sores, which usually last about 7 to 10 days.
Ointments can be used from the first signs of herpes to the total disappearance of the sores, and should be used with medical advice and guidance. However, if there is no improvement in symptoms, it may be necessary to use antiviral pills, which can only be used with a doctor's prescription. Check out the main pills used in the treatment of cold sores.

Cautions when using ointments
Some important precautions during the treatment of cold sores with ointment are:
- Use the ointment at the correct times, as directed by the doctor;
- Wash your hands before and after applying the ointment, with water and mild soap, to prevent the infection from getting worse or spreading to other parts of the body;
- Avoid kissing or having contact with other people's herpes sores while there are blisters or sores on the lips;
- Avoid sharing utensils, towels or lip balm with others;
- Avoid eating spicy foods or citrus fruits to avoid irritating the mouth sore.
It is also recommended to consume some foods, such as peas, fish or peanuts, which are rich in lysine, a protein that acts by inhibiting the growth of the Herpes simplex virus, which can help to complement the treatment with the ointment and accelerate skin healing.
