Shingles is a viral infection that causes a painful rash. This study aims to find out whether taking a low dose of amitriptyline soon after getting shingles can prevent the long-term pain associated with shingles

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

Participants take tablets nightly for 10 weeks: half will be given low-dose amitriptyline and the other half will get placebo (dummy) tablets. Pain is assessed at 90 days after rash onset.


Patients aged over 50 years who have been diagnosed by their GP with shingles.

If starting amitriptyline early on does help, it is a cheap medicine that would prevent prolonged, difficult-to-treat pain for thousands of people. However, amitriptyline commonly causes side effects such as dizziness, dry mouth and constipation. It can also cause problems when used together with some other tablets. This study is needed so doctors can be sure that any benefits outweigh any harm.
