Aciclovir per infezioni virali

About aciclovir

Aciclovir is used to treat two common viral infections - varicella-zoster and herpes simplex. The varicella-zoster virus is the cause of varicella e fuoco di Sant'Antonio. Herpes simplex viruses cause herpes labiale e herpes genitale. Aciclovir works by preventing viruses from multiplying, and this reduces the severity of the infection and stops it from spreading. As well as treating infections, aciclovir can also be prescribed to prevent some viral infections from occurring. This is particularly the case in people who have a lowered immune system.

Although some herpes infections (for example, cold sores) can be treated with creams or ointments, more severe infections need to be treated with tablets or medicine taken by mouth. This leaflet provides information on how to take aciclovir tablets and medicine. Information about the topical forms of aciclovir (creams and ointments) is not included in this leaflet. See the separate medicine leaflets called Crema di aciclovir e Pomata oculare di aciclovir for more information about how to use these preparations.

Before taking aciclovir

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking aciclovir it is important that the person prescribing it for you knows:

• If you are pregnant or breastfeeding (although aciclovir is not known to be harmful to a baby).

• Se hai problemi con il funzionamento dei tuoi reni.

• 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.

• Se hai mai avuto una reazione allergica a un medicinale.

How to take aciclovir

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

• Your dose will depend upon the type of infection you have, so take aciclovir exactly as your doctor tells you to. Typically, doses range from 200 mg to 800 mg, and these doses are taken either three, four or five times daily. Your doctor or pharmacist will tell you what dose is right for you, and this information will also be printed on the label of the pack to remind you about what was said to you.

• Space out your doses evenly during the day. You can take aciclovir either with or without food.

• Even if you feel your infection has cleared up, keep taking aciclovir until the course is finished (unless your doctor tells you to stop sooner). This is to prevent the infection from coming back. The course of treatment prescribed could last between 2-10 days. If you still feel unwell after finishing the course, go back to see your doctor.

• If you have been prescribed a dispersible tablet - these can be stirred into a small glassful (50 ml) of water to make them easier to swallow. You can, however, swallow them as normal if you prefer.

• Se dimentichi di prendere una dose, prendila appena te ne ricordi e poi continua come prima. Cerca di prendere il numero corretto di dosi ogni giorno, ma non prendere due dosi contemporaneamente per compensare una dose dimenticata.
  

Ottenere il massimo dal tuo trattamento

• You should drink plenty while you are on aciclovir to keep your kidneys working well. Drinking water is best, but hot drinks and non-alcoholic cold drinks are also suitable.

• Aciclovir could cause your skin to become more sensitive to sunlight than it is usually. Avoid strong sunlight and sunbeds, and use a sun cream with a high sun protection factor until you know how your skin reacts.

• If you have been prescribed aciclovir for genital herpes, do not have sex while you have sores or blisters. Even after these have healed, there is still a small chance that you may pass on the virus when you have sex - using a condom reduces this risk.

• If you are having an operation or any other medical treatment, tell the person carrying out the treatment that you are taking aciclovir.
