What the trials show
Gabapentinoids for neuropathic pain
Supported by trial evidenceThey help a minority of people with nerve pain: about one extra person in nine gains meaningful relief.
The evidence
A 2025 meta-analysis of 313 randomised trials for the Neuropathic Pain Special Interest Group found a number needed to treat of 8.9 (95% CI 7.4 to 11.1) for the gabapentinoids, with one extra person withdrawing because of adverse events for every 26 treated. Tricyclic antidepressants (number needed to treat 4.6) and serotonin and noradrenaline reuptake inhibitors (7.4) were also recommended first-line. Capsaicin and lidocaine plasters received weak, second-line recommendations, and opioids a weak, third-line recommendation 31.
In practice
The medicines section explains anticholinergic burden, which is relevant when a tricyclic antidepressant is considered for an older person.
Pregabalin for sciatica
Not supportedIn an Australian trial, pregabalin did not reduce sciatica leg pain and caused more side effects, mainly dizziness.
The evidence
In 209 people with sciatica, leg pain at eight weeks was no better with pregabalin than with placebo (adjusted difference 0.5 on a 10-point scale, 95% CI −0.2 to 1.2), and no better at one year. There were 227 adverse events with pregabalin against 124 with placebo, and dizziness was more common 32.
Gabapentinoids with opioids
In Ontario, among people taking opioids, also taking gabapentin was associated with a higher risk of opioid-related death (adjusted odds ratio 1.49, 95% CI 1.18 to 1.88). This was an observational study of people on public drug coverage, and unmeasured differences between groups may explain part of the association 33.
The combination is common in Australian aged care. In 12 South Australian nursing homes, 62% of residents prescribed a gabapentinoid were also prescribed an opioid, and the authors called for attention to the central nervous system-active polypharmacy that results 5.
Questions for a review
-
What is it treating, and is the pain neuropathic?
-
Has it helped, judged against a goal set when it was started?
-
Is the resident also taking an opioid or a sedative?
-
Has there been dizziness, unsteadiness, drowsiness or new confusion since it started?
