Aciclovir cream contains the antiviral, aciclovir. It destroys the herpes simplex virus that is responsible for causing cold sores to appear around the lips and face. If the cold sore outbreak is caught early, at the 'tingle' phase, Aciclovir cream can sometimes prevent the cold sore from coming out. In most cases, it can help a cold sore to heal within 4 - 5 days.
Recurrent cold sores often appear in the same place. The skin in this area often tingles or burns before a cold sore comes out in to a blister around the lip. Aciclovir should be applied as soon as the tingle is felt.
Aciclovir cream is suitable for ordering online if you suffer with recurrent cold sores that have been diagnosed by your doctor. It should not be used in children or to treat genital herpes. If cold sores appear around the nose or are yellow and crusty, it may be a sign of impetigo and requires treatment from your doctor.
How to apply Aciclovir cream
Wash your hands before and after applying the cream. This prevents spreading the cold sores from spreading and helps to prevent them becoming infected.
Squeeze a small amount of cream onto your finger and gently rub into the cold sore.
Apply Aciclovir cream to the cold sore(s) FIVE times daily (roughly every four hours).
Treatment should be continued for FOUR days even if the cold sore has healed. If it has not healed, treatment can be continued for a further FIVE days.
If your cold sore has not healed after nine days treatment with Aciclovir you should see your doctor for further advice.
Aciclovir cream is not effective if it is started more than five days after your cold sore has come out. Do not use Aciclovir cream in this situation. Always try to apply Aciclovir cream as soon as you feel a cold sore starting.
