Prevalence and relationship with health of off-label and contraindicated drug use in the United States: a cross-sectional study.
Article in Journal of pharmaceutical policy and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOff-label and contraindicated prescription drug use can result in adverse health outcomes. Despite concerns, the extent and characteristics of such usage patterns remain underexplored in the American population. We conducted a cross-sectional study analysing outpatient prescription data between 2016 and 2021 to determine the prevalence of off-label and contraindicated drug use.
methodsThe study used labelling information from DrugCentral and the Medical Expenditure Panel Survey, focusing on the American non-institutionalised population. We analysed 9872 drug-indication and 34,138 drug-contraindication pairs among 46,770 patients and 1,596,753 prescriptions. Linear and probit regressions, and a double machine learning approach, were employed to assess associations between off-label/contraindicated use, health status, and healthcare utilisation, adjusting for demographic and health-related factors.
resultsOverall, 75% of prescriptions were for labelled indications, while 25% were off-label; 54% were contraindicated. Only 33% of prescriptions were both indicated and not contraindicated. Off-label prescriptions had a lower contraindication rate (48.8%) compared to indicated prescriptions (56.2%). Improved health status and reduced medical expenditure correlated with lower off-label prescription rates. Notably, newer drugs (post-1997) had a higher rate of prescriptions that were both indicated and not contraindicated (43%) compared to older drugs (pre-1979, 21%). Patterns of off-label and contraindicated use were consistent across racial and educational demographics.
conclusionOff-label and contraindicated drug use is prevalent in outpatient prescriptions and is associated with worse health outcomes and increased healthcare utilisation. These findings suggest a need for enhanced monitoring and regulatory measures to minimise risks associated with inappropriate prescription practices.
