Abstract
Background. Concurrent use of dietary supplements and drugs may result in omplications of pharmacotherapy due to possible interactions between their ngredients. Objectives. The aim of the survey was to estimate the intake of dietary supplements in a group of women over 50 and to analyse the risk of interactions between the ingredients of dietary supplements and drugs taken by the women. Material and Methods. The study was carried out among 146 women over 50 years of age. Questionnaire included detailed questions on the type of prescription drugs, OTC (over-the-counter) drugs, and dietary supplements taken. The risk of interactions was determined on the basis of chemical composition of the drugs and supplements pecified by the manufacturer, by comparing the obtained data with literature reports on known interactions. Results. The analysis has shown that 88.4% of respondents constantly took prescription drugs, 44.5% of them took OTC drugs, and 66.4% of respondents took dietary supplements throughout the survey period. It has been found that 71.3% of surveyed women taking prescription drugs, took dietary supplements as well. Among women taking supplements and drugs, 36.9% of respondents were taking them concurrently, 60.9% kept such an interval, but only 21.8% of them waited for at least two hours. It has been found that the drug-supplement interactions might occur in 35.8% women under the survey. Conclusions. The analysis of the obtained results has revealed that taking dietary supplements by the group under survey was frequent, and the risk of interactions between dietary supplements and drugs was significant. It is recommended that doctors ask their patients about taken supplements during regular check-ups, and inform them about possible interactions between dietary supplements and drugs. Moreover, appropriate would be to change the labelling of dietary supplements, so that the packaging provides information on possible interactions between their ingredients and drugs.
