Summary: Background: Analgesics prescriptions may provide a marker for identifying individuals at higher risk of suicide. In particular, awareness of which analgesics are implicated may help clinicians assess and modify risk. Method: A case–control study in England using the Clinical Practice Research Datalink (for primary care records) linked with hospital and national mortality electronic registries. We included patients aged ≥15 who died by suicide between 2001 and 2019 (N = 14,515), to whom we individually matched 580,159 controls by suicide date and general practice (N = 594,674). Odds ratios (ORs) for suicide, controlled for age and sex, were assessed using conditional logistic regression. Findings: Suicide risks were highest in those prescribed adjuvant analgesics (pregabalin, gabapentin and carbamazepine) (adjusted OR 4.07; 95% confidence intervals CI: 3.62–4.57), followed by those prescribed opioids (adjusted OR 2.01; 95% CI: 1.88–2.15) and those prescribed non-opioid analgesics (adjusted OR 1.48; 95% CI: 1.39–1.58) compared to those not prescribed these medications. By individual analgesic, the highest suicide risks were seen in patients prescribed oxycodone (adjusted OR 6.70; 95% CI: 4.49–9.37); pregabalin (adjusted OR 6.50; 95% CI: 5.41–7.81); morphine (adjusted OR 4.54; 95% CI: 3.73–5.52); and gabapentin (adjusted OR 3.12; 95% CI: 2.59–3.75). Suicide risk increased linearly with the number of analgesic prescriptions in the final year (p
