Reported utilisation of prescription drug use concurrently with herbal or vitamin products have increased, placing an estimated 15 million patients at risk of potential drug-supplement interactions. This systematic review aims to consolidate relevant herb and supplement interactions data available for some of the more common classes of interactions experienced by clinicians. These classes include: hypoglycaemic/hyperglycaemics; hypotensive/hypertensives, diuretics, sedatives, cardiac glycosides, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, laxatives, immunomodulators, agents that may increase the risk of bleeding or clotting, agents that may be hepatotoxic, agents that may have hormonal properties, and agents with cytochrome P450 enzyme activity. The format is designed to promote use as a decision support tool for healthcare providers.
