If you or someone in your family has experienced a serious side effect to a health product, you are encouraged to report the experience to your health care professional (eg, physician, pharmacist). Your health care provider can provide additional clinical information and complete a copy of the side effect reporting form.

Side effects reports are analyzed to discover potential health product safety signals. Some important reactions may take an extremely long time to develop or occur infrequently. Continued monitoring of adverse reactions is thus essential to maintain a comprehensive safety and effectiveness profile of health products.
