Nortriptyline is an antidepressant medicine that's used to treat depression, but can also be used to treat nerve pain.
It's thought that nortriptyline works by increasing a chemical called serotonin in the brain. This helps to improve your mood.
For pain relief, it works by changing the way your nerves receive pain signals, so your pain goes away.
Nortriptyline is available on prescription. It comes as tablets and as a liquid that you swallow.
