Embase, Cochrane Central Register of Clinical Trials (CENTRAL), CINAHL, and LILACS.

Study selection Randomised controlled trials assessing the efficacy and tolerability of drugs versus placebo or other treatment for sciatica.

Data extraction Two independent reviewers extracted data and assessed methodological quality using the PEDro scale. Pain and disability outcomes were converted to a common 0 to 100 scale. Data were pooled with a random effects model, and the GRADE approach was used in summary conclusions.

Results Twenty three published reports met the inclusion criteria. The evidence to judge the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antidepressants, anticonvulsants, muscle relaxants, and opioid analgesics ranged from moderate to low quality. Most of the pooled estimates did not favour the active treatment over placebo. The pooled results of two trials of corticosteroids (mean difference in overall and leg pain −12.2, 95% confidence interval −20.9 to −3.4) and a single trial of the anticonvulsant gabapentin for chronic sciatica (mean difference in overall pain relief −26.6, −38.3 to −14.9) showed some benefits but only in the short term. The median rate of adverse events was 17% (interquartile range 10-30%) for the active drugs and 11% (3-23%) for placebo. Trial limitations included failure to use validated outcome measures, lack of long term follow-up, and small sample size.

Conclusions As the existing evidence from clinical trials is of low quality, the efficacy and tolerability of drugs commonly prescribed for the management of sciatica in primary care is unclear.
