Pregabalin: UK Information Guide

Introduction

Pregabalin is used to treat neuropathic (nerve) pain, certain types of epilepsy as an add-on treatment, and generalised anxiety disorder. It calms over-active nerve signalling in the central nervous system. In the UK it is prescription-only and a controlled medicine because of its potential for misuse and dependence. This UK-focused guide explains what Pregabalin is, how it works, how it is usually taken, common and serious side effects, safety points, and frequently asked questions. It is general information only — not personal medical advice.

What Is Pregabalin?

Pregabalin is used to treat neuropathic (nerve) pain, certain types of epilepsy as an add-on treatment, and generalised anxiety disorder. It calms over-active nerve signalling in the central nervous system. In the UK it is prescription-only and a controlled medicine because of its potential for misuse and dependence.

Generic products include Nervigesic 300mg, Nervigesic 450mg and Pregagesic 300.

How Does It Work?

Pregabalin binds to the α2δ subunit of voltage-gated calcium channels in the central nervous system, reducing release of excitatory neurotransmitters. This dampens abnormal nerve signalling that underlies neuropathic pain and can also help in certain seizure and anxiety indications. It is taken regularly, not only when symptoms occur, and the dose is usually built up gradually.

How Is It Usually Taken?

Take exactly as prescribed. Treatment is usually started low and increased gradually under medical supervision. Do not stop suddenly — the dose must be tapered under guidance. Do not drive until you know how it affects you. Avoid alcohol and opioids combinations.
