Medicines for Neuropathic pain

What it is

Neuropathic pain is pain that comes from damage to, or a problem affecting, the nerves that carry pain signals, rather than from injury to skin, muscle or bone. People often describe it as burning, shooting, stabbing, tingling or like electric shocks, and the affected area can become unusually sensitive, so that even a light touch or normal clothing hurts. Common causes include nerve damage from diabetes, shingles, an injury or surgery, trapped or compressed nerves, and conditions affecting the nervous system. Because it arises from the nerves themselves, neuropathic pain behaves differently from ordinary ("nociceptive") pain and often does not respond well to standard painkillers — which is why it is treated with a distinct group of medicines.

How it is treated

Treatment aims to reduce pain to a level that improves daily function, sleep and quality of life, while being clear that the goal is usually meaningful partial relief rather than complete freedom from pain. Where there is a treatable underlying cause, such as poorly controlled diabetes or a compressed nerve, addressing it is part of the plan. The first-line medicines are different from ordinary painkillers: certain antiepileptic-type drugs (the gabapentinoids), tricyclic antidepressants and the SNRI duloxetine are all established options, chosen and often tried in turn according to the person, other conditions and how well each is tolerated. These medicines are usually introduced gradually and reviewed, with one swapped for another if it does not help enough or is not tolerated. Non-drug approaches — physical activity, pacing, psychological support and pain-management programmes — are important alongside medication, and ordinary painkillers generally play a limited role.
