Antiviral tablets can shorten the attack, control the rash, and minimise damage to the nerves, if taken early enough. They should be started within two to three days of the rash appearing.

Antiviral tablets can also prevent an outbreak of shingles in people who have a weakened immune system and who come into contact with the illness.

Your doctor may also prescribe painkillers and also antibiotics if there is a secondary infection.

Although they were originally developed to treat depression, many doctors prescribe a low dose of antidepressant drugs (such as amitriptyline or nortriptyline) every night, starting as soon as shingles is diagnosed. This can help to prevent long-term pain.

Looking after yourself

To stop the rash irritating it's a good idea to wear loose fitting, comfortable clothes preferably in a natural fibre such as cotton.

You may find that vitamins help, especially those related to skin and nerve healing like vitamins A, E and B-complex. Your immune system will need a boost so make sure your diet contains plenty of fresh fruit, vegetables and cereals. Stress can also affect your immune system so try not to worry.
