Potential Interactions Between Pharmaceuticals and Natural Health Products in Canada
Bibliographic record
Abstract
This study sought to measure the extent to which potentially interacting combinations of natural health products (NHPs) and drugs are used in the Canadian adult population. Data were obtained from the Statistics Canada 2000-2001 National Population Health Survey. A total of 11 424 adults completed the survey. Of the survey participants, 9.3% reported the use of at least 1 natural health product in the prior 2 days. Among natural health product users, 57% also used a conventional medicine with systemic exposure in the same time period. A minimum of 1 potential drug-NHP interaction was identified in 28.4% of such combination users. Most interactions (90%) were of unknown clinical significance. Female gender, older age, lower education, and the presence of diabetes and high blood pressure were associated with a higher risk of having at least 1 potential interaction. Health professionals need to maintain a working knowledge of common potential drug-NHP interactions, to dialogue with all patients regarding the use of natural health products, and to remain vigilant in reporting all suspected interactions and adverse events involving natural health products. Regulatory agencies should also capture and assess reports of drug-NHP interactions more effectively.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
