Famciclovir para infecções virais

About famciclovir

Famciclovir is used to treat infections caused by two common viruses - herpes zoster and herpes simplex. The herpes zoster virus is the cause of herpes zoster. Herpes simplex viruses cause herpes genital. You will have been prescribed famciclovir to treat either shingles, or genital herpes. Famciclovir works by preventing viruses from multiplying, and this reduces the severity of the infection.

Before taking famciclovir

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 famciclovir it is important that your doctor knows:

• Se você está grávida, tentando ter um bebê ou amamentando.

• Se você tiver algum problema com o funcionamento do seu fígado, ou se tiver algum problema com o funcionamento dos seus rins.

• Se você estiver tomando ou usando qualquer outro medicamento. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

How to take famciclovir

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about famciclovir, 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 famciclovir exactly as your doctor tells you to. Typically, doses range from 250 mg to 750 mg, and doses are taken either one, two or three 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.

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

• Even if you feel your infection has cleared up, keep taking the tablets until the course is finished (unless your doctor tells you to stop sooner). This is to prevent the infection from coming back. A course of treatment usually lasts for around 5-10 days, although some people need to take famciclovir for only one day, and other people need a course lasting for several months. If you still feel unwell after finishing your course of treatment, go back to see your doctor.

• Se você esquecer de tomar uma dose, tome-a assim que se lembrar e depois continue como antes. Tente tomar o número correto de doses a cada dia, mas não tome duas doses ao mesmo tempo para compensar uma dose esquecida.

Obtendo o máximo do seu tratamento

• If you have been prescribed famciclovir 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 famciclovir.
