About cold sores

What are cold sores?

Cold sores are small blisters developing on or around the edge of the lips. They can split and bleed slightly which can be painful. Cold sores are common and affect men and women of all ages. A cold sore develops when you are infected with either Herpes Simplex Virus-1 (HSV-1) or Herpes Simplex Virus-2 (HSV-2)  around the mouth. This is usually contracted via direct contact with another person who has a cold sore, such as kissing, or by sharing toiletries such as lip balm. It can also be caught via oral sex with someone who has genital herpes.

Being infected with HSV-1 or HSV-2 will not always cause symptoms. If you are not currently symptomatic there is no cause for concern.

Who can get cold sores?

Cold sores can affect anyone who has come into contact with the virus. Once you have been infected, a cold sore can flare up at any time but can be well-managed with appropriate medical care.

Cold sores are often triggered when you are run down or stressed.

You have a higher risk of developing cold sores if you:

  • kiss someone with unhealed cold sore blisters
  • share cosmetic products with someone who has cold sores
  • have oral sex with someone who has genital herpes

To reduce your risk of cold sores you should avoid direct contact with someone else’s cold sores.


Cold Sore Treatment

Cold sores can be treated with antiviral medication, which reduces your healing time.

We offer the following cold sore treatments:

  • Aciclovir treatment therapy
  • Aciclovir suppressive therapy

A longer course of suppressive therapy can reduce the number of cold sore outbreaks you have over a period of time. The short course treatment therapy helps to ease a current outbreak more quickly.

Cold Sore Symptoms

Cold sores are not generally dangerous but can sometimes be embarrassing and uncomfortable. Development of a cold sore blister starts with a strange tingling sensation on or around the lips. Small blisters then form and can crack and bleed which can be painful.

How is aciclovir taken?

Aciclovir tablets can be taken to heal existing cold sores or to suppress recurrent bouts.

When treating an acute bout of oral herpes, you need to take one 200mg aciclovir tablet fives times a day for a course of five days. You should start your treatment as soon as you notice the first symptoms.

For suppression treatment, take one 200mg tablet four times a day for a minimum of three months. Ideally, suppression treatment should continue for six to twelve months. It is very unlikely that you experience another bout while taking suppression treatment. However, if this does happen you can take one 200mg aciclovir tablet fives times a day for a course of five days.

You need to drink plenty of water while taking aciclovir to prevent the side effect of dehydration.

Who can take aciclovir?

Your doctor may not wish to prescribe Aciclovir for you if, in the past, you have had any trouble or allergic reactions to aciclovir, valaciclovir, other medicines or ingredients in this medicine; or if you are dehydrated, elderly, immunocompromised, or if you have kidney problems.

Drink plenty of water when taking this medicine.

These medicines and types of medicines can interact with Aciclovir:

  • cimetidine
  • mycophenolate mofetil
  • probenecid
  • immunosuppressant medicines

Which side effects can aciclovir cause?

Aciclovir can cause the following side effects:

  • headaches and feeling sick
  • diarrhoea
  • dizziness
  • itchiness/rashes
  • tummy pain
  • fatigue

For a list of all known side effects, read the patient leaflet supplied with your medication.
