Herpes is contagious from the moment you first feel tingling or other signs of the disease, and until the wounds heal completely.
To alleviate the symptoms, you can use:
In pharmacies, electronic devices are also sold that, as manufacturers promise, act on herpes using light or a laser. Some people find such devices useful, but there is very little research to prove their effectiveness.
If you regularly have a cold on your lips, use antiviral creams as soon as you feel tingling.
After the appearance of blisters, they are unlikely to help.
