INTRODUCTION: Due to the risk of overdoses increase especially with methadone, a reinforced monitoring has been set up by the French Addictovigilance Network following the first lockdown related to coronavirus disease 2019 (COVID-19). In this context, we managed a specific study to analyze overdoses related to methadone in 2020 compared to 2019.
MATERIAL AND METHODS: We analyzed methadone-related overdoses which occurred in 2019 and 2020 from two sources: DRAMES program (deaths with toxicological analysis) and the French pharmacovigilance database (BNPV) (overdoses that did not lead to death).
RESULTS: Data from DRAMES program in 2020 show methadone as the first drug involved in deaths as well as an increase in deaths: in number (n=230 versus n=178), in proportion (41% versus 35%) and number of deaths per 1000 exposed subjects (3.4 versus 2.8). According to BNPV, the number of overdose increased in 2020 compared to 2019 (98 versus 79; i.e., 1.2-fold increase) particularly during several target periods: first lockdown, end of lockdown/summer period and second lockdown. In 2020, a higher number of cases were observed in April (n=15) and May (n=15). Overdoses and deaths occurred in subjects enrolled in treatment programs or not (naïve subjects/occasional users who obtained methadone from street market or family/friends). Overdoses resulted from different factors: overconsumption, multiple drug use with depressants drugs or cocaine, injection, consumption for sedative, recreational purposes or voluntary drug poisoning.
DISCUSSION/CONCLUSION: All these data show an increase of morbidity and mortality related to methadone during COVID-19 epidemic. This trend has been observed in other countries.
