Adhd medication1/7/2024 1 According to a 2006 US Food and Drug Administration (FDA) advisory committee briefing on the safety of ADHD medications, more than 1.5 million US adults were taking stimulants in 2005, and adults received approximately 32% of all issued prescriptions. Apparent protective associations likely represent healthy-user bias.īetween 20, use of medications labeled for treatment of attention-deficit/hyperactivity disorder (ADHD) increased even more rapidly in adults than in children. The adjusted RR for current use vs remote use was 1.03 (95% CI, 0.86-1.24) for new use vs remote use, the adjusted RR was 1.02 (95% CI, 0.82-1.28) the upper limit of 1.28 corresponds to an additional 0.19 events per 1000 person-years at ages 25-44 years and 0.77 events per 1000 person-years at ages 45-64 years.Ĭonclusions Among young and middle-aged adults, current or new use of ADHD medications, compared with nonuse or remote use, was not associated with an increased risk of serious cardiovascular events. Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI, 0.63-0.94). The multivariable-adjusted rate ratio (RR) of serious cardiovascular events for current use vs nonuse of ADHD medications was 0.83 (95% CI, 0.72-0.96). Results During 806 182 person-years of follow-up (median, 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. Main Outcome Measures Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke, with comparison between current or new users and remote users to account for potential healthy-user bias. Each medication user (n = 150 359) was matched to 2 nonusers on study site, birth year, sex, and calendar year (443 198 total users and nonusers). Participants were adults aged 25 through 64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Objective To examine whether current use of medications prescribed primarily to treat ADHD is associated with increased risk of serious cardiovascular events in young and middle-aged adults.ĭesign, Setting, and Participants Retrospective, population-based cohort study using electronic health care records from 4 study sites (OptumInsight Epidemiology, Tennessee Medicaid, Kaiser Permanente California, and the HMO Research Network), starting in 1986 at 1 site and ending in 2005 at all sites, with additional covariate assessment using 2007 survey data. These agents can increase heart rate and blood pressure, raising concerns about their cardiovascular safety.
