Different Australian jurisdictions implemented different COVID\u201019 restrictions. We used Australian national pharmacy dispensing data to conduct interrupted time series analyses to examine the incidence and prevalence of opioid dispensing in different jurisdictions. Following nationwide COVID\u201019 restrictions, the incidence dropped by \u22120.40 (95% confidence interval [CI]: \u22120.50, \u22120.31), \u22120.33 (95% CI: \u22120.46, \u22120.21) and \u22120.21 (95% CI: \u22120.37, \u22120.04) per 1000 people per week and the prevalence dropped by \u22120.85 (95% CI: \u22121.39, \u22120.31), \u22120.54 (95% CI: \u22121.01, \u22120.07) and \u22120.62 (95% CI: \u22120.99, \u22120.25) per 1000 people per week in Victoria, New South Wales and other jurisdictions, respectively. Incidence and prevalence increased by 0.29 (95% CI: 0.13, 0.44) and 0.72 (95% CI: 0.11, 1.33) per 1000 people per week, respectively in Victoria post\u2010lockdown; no significant changes were observed in other jurisdictions. No significant changes were observed in the initiation of long\u2010term opioid use in any jurisdictions. More stringent restrictions coincided with more pronounced reductions in overall opioid initiation, but initiation of long\u2010term opioid use did not change.<\/jats:p>","DOI":"10.1111\/bcp.15577","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T17:24:16Z","timestamp":1666891456000},"page":"914-920","source":"Crossref","is-referenced-by-count":9,"title":["COVID\u201019 restrictions and the incidence and prevalence of prescription opioid use in Australia \u2013 a nationwide study"],"prefix":"10.1111","volume":"89","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6458-1279","authenticated-orcid":false,"given":"Monica","family":"Jung","sequence":"first","affiliation":[{"name":"Monash Addiction Research Centre, Eastern Health Clinical School Monash University  Melbourne Victoria Australia"},{"name":"Centre for Medicine Use and Safety, Faculty of Pharmacy and Pharmaceutical Sciences Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dickson","family":"Lukose","sequence":"additional","affiliation":[{"name":"Monash Data Futures Institute Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5341-1055","authenticated-orcid":false,"given":"Suzanne","family":"Nielsen","sequence":"additional","affiliation":[{"name":"Monash Addiction Research Centre, Eastern Health Clinical School Monash University  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
