Doctor Fox supplies Aciclovir cream on prescription for the treatment of cold sores. Dr Fox also provides information about cold sores and their treatment. We carry out online consultations to issue prescriptions for aciclovir cream.
Cold sores break out when a dormant virus under the skin becomes active. Cold sores come up time and again in the same places, usually around the lips. Cold sores come up in the same place because the virus causing them remains dormant under the skin in the same place between outbreaks of the sores.
How to order
From start to finish most cold sores heal up in 7 to 10 days. Cold sores usually start as minute blisters that usually break within a few hours of appearing. This produces the familiar shallow open cold sores we are all familiar with. During the period the skin surface is broken the cold sore virus will be shed from the surface. The sore is infectious at this stage.
People who do not have immunity to the cold sore virus from a previous infection with the virus can catch the infection by contact with open cold sores. For this reason cold sore are sometimes called the ‘kissing disease’.
Cold sores can be settled down by the aciclovir cream. Aciclovir cream is an antiviral cream and is available on prescription. This cream reduces the activity of the cold sore virus and reduces the severity and duration of sores. Aciclovir cream works best if it is applied to sores early in an outbreak. If a sore has been present for more than a day or two before treatment is started aciclovir cream will have little effect. It can be useful to have a supply of aciclovir cream in the fridge for use when it is needed.
Aciclovir cream does not eliminate the cold sore virus from the body. No treatment is available currently which will entirely remove the virus. Aciclovir cream and tablets and other antiviral treatments settle outbreaks of the virus temporarily.
Sores that have not healed after 10 days may not be cold sores and should be assessed by a doctor. Sores that are spreading to new areas may not be cold sores. Spreading sores are more likely to be a surface bacterial infection called impetigo. Further information on cold sores.
Each outbreak of a cold sore is usually preceded by tingling of the skin at the site where the sore is about to come up. The sores themselves, once they appear, usually burn and sting. People who get cold sores often know when their sores are about to appear because they get a familiar tingling in the skin first.
The cold sore virus is often picked up in childhood. Touching contact with an active sore is all that is required to catch the cold sore virus. A child with an active sore can transfer the virus to another child by touch or by transferring the virus to objects that are then touched by other children. This sort of contact can not be avoided and children with active sores are not excluded from nurseries or school.
The virus producing cold sores comes from the herpes family of viruses, the herpes simplex virus. There are various types of herpes simplex virus broadly divided into herpes type 1 and herpes type 2. The cold sore virus producing cold sores around the lips and on the face is similar, or even sometimes the same virus, that produces the sores of genital herpes. Cold sores can be picked up from contact with an open sores in the genital region. This is becoming a more frequent way for the herpes virus to be transmitted. Aciclovir cream will not prevent this transmission.
When herpes is first contracted (picked up) it often produces multiple sores, often in the mouth. Young children with their first infection with the cold sore virus are often markedly unwell with fever, swollen glands and pain. Infection usually settles down fully within a week or so. The sores heal up and disappear. It is reactivation of the cold sore virus later in life that produces the typical cold sore. Cold sores can be picked up later in childhood or adolescence and even in adulthood. A high proportion of the adult population have had herpes infection at some time in their lives. Many of these people do not go on to suffer from cold sores.
It is not known why some people have recurrent cold sores after a primary infection. Some people just seem to be prone to them. Even people who are prone to cold sores usually build up immunity to the virus eventually and stop getting sores or get them only infrequently.
The start of a cold sore may be triggered by environmental factors. Wind and sunburn are known to trigger cold sores. Cold sores are also said to be a sign a person is run down. Most people who suffer from cold sores are perfectly healthy. Only when a whole mass of sores breaks out at the same time or when cold sores will not heal is it necessary to check for reduced immunity.
