When seeking advice, tell your health professional about prescribed medicines, over-the-counter medicines, supplements and herbal products you use or are thinking about using.

Take extra care in higher-risk situations

Check with a doctor or pharmacist before using herbal products if you take regular medicines, are preparing for surgery, are pregnant or breastfeeding, or are considering a product for a child or for a significant health concern.

Do not stop prescribed treatment on your own

Do not stop or change prescribed medicines because of information on a website or a product label. Ask the clinician who manages your care or a pharmacist for advice about your own situation.
