Crema di aciclovir

About aciclovir cream

Aciclovir is an antiviral agent. It works by attacking the herpes simplex virus, of which there are two types:

• Type 1 herpes simplex virus is the usual cause of herpes labiale around the mouth. It also causes up to half of the cases of genital herpes.

• Type 2 herpes simplex virus usually only causes herpes genitale. It can sometimes cause cold sores.

Aciclovir does not kill the herpes simplex virus, but it does prevent it from multiplying. This means that, although it may have little effect on existing blisters, it can prevent them from getting worse. If you use aciclovir cream as soon as your symptoms start then it will reduce the severity and duration of the symptoms. Aciclovir cream is available on prescription for the treatment of cold sores and genital herpes infections. You can also buy some brands without a prescription in order to treat cold sores.

There are other preparations of aciclovir available which are not dealt with by this medicine leaflet. See the separate leaflets called Aciclovir per infezioni virali e Pomata oculare di aciclovir for more information about other formulations of aciclovir.

Before using aciclovir cream

To make sure that this is the right treatment for you, before you start using aciclovir cream it is important that your doctor or pharmacist knows:

• If you are pregnant. This is because, if you are expecting a baby, medicines should only be used on the advice of a doctor.

• If your immune system is not working as well as it should (for instance, if you have HIV or AIDS). This is because you may need additional antiviral treatment.

• Se stai assumendo o utilizzando altri medicinali. Questo include qualsiasi medicinale che stai assumendo e che è disponibile per l'acquisto senza prescrizione, così come i medicinali a base di erbe e complementari.

• If you have ever had an allergic reaction to a medicine or skin product.

How to apply aciclovir cream

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about using aciclovir cream and will provide you with a full list of the side-effects which you could experience from using it.

• Apply the cream five times a day. The best way to do this is to use it every four hours during the day (suggested times are 7 am, 11 am, 3 pm, 7 pm and 11 pm). Dab the cream on to the area rather than rubbing it in. This will minimise any damage to the blisters, which could cause pain and spread the virus around.

• Start using the cream at the first sign of infection (for instance, when you first feel your skin tingling) and continue to use it for five days. This is often sufficient time for the sore to heal but you can continue to use the cream for a further five days if needed. Remember to wash and dry your hands before and after using aciclovir, to prevent spreading any infection.

• If you forget to use the cream, apply it as soon as you remember and then continue using it again at your usual times.

Ottenere il massimo dal tuo trattamento

• Try to keep the areas affected by blisters as clean and dry as possible and only touch the sores when you apply the cream.

• Aciclovir cream is not intended for use in your mouth or vagina, or near your eyes. This is because it may irritate these parts of your body. If you have sores in any of these areas, you should make an appointment to see your doctor, as alternative preparations can be prescribed which will be suitable for you to use.

• When you have a cold sore you should not kiss anyone or allow anyone to come into skin contact with the sore. In particular, avoid kissing newborn babies and anyone who has a poor immune system. When you have no symptoms, you are not usually infectious.

• Genital herpes simplex virus is very contagious when blisters are present. You should not have sex from the time your symptoms first start until they are fully over, as there is a high chance of passing on the virus.

Can aciclovir cream cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the ones associated with creams containing aciclovir. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
