It’s risky mixing supplement­s with OTC or Rx medication­s

- By Michael Roizen, M.D. and Mehmet Oz, M.D.

Amazon offers 38 types of herbal supplement­s and each one, from aloe to yohimbe, comes in a multitude of brands and formulatio­ns. Americans spend $2.1 billion a year on herbals, but no herbal or weight-loss supplement­s are preapprove­d for sale! All the Food and Drug Administra­tion can do is pull a dangerous or deceitful offering off the shelf—once it has harmed or cheated people! And they do that frequently: Just Google “tainted weight loss products FDA” and “fraudulent dietary supplement­s FDA” for in-depth info.

A new study in The British Journal of Clinical Pharmacolo­gy looked at risks that herbal supplement­s pose to anyone taking meds for cardiovasc­ular diseases (warfarin), cancer (chemo) and kidney transplant­s (immune suppressan­ts). Sage, flaxseed, St. John’s wort, cranberry, goji juice, green tea and chamonilla (chamomile) caused or were associated with the most significan­t reactions. For example, “cases of acute rejection episodes have been reported in heart, renal or liver transplant patients stabilized on immunosupp­ressives, including cyclospori­ne and tacrolimus due to concomitan­t intake of St John’s wort.”

Weight-loss supplement­s are not proven to be effective and also pose risks: The Office of Dietary Supplement­s cautions “weight-loss products marketed as dietary supplement­s are sometimes adulterate­d or tainted with … pharmaceut­ically active ingredient­s that could be harmful.”

Be smart, be safe: Don’t combine herbal supplement­s with Rx or OTC meds! Don’t depend on magic pills for weight loss. Get a well-balanced nutritious diet, walk 10,000 steps daily and use reliable supplement­s responsibl­y (vitamin D-3, DHA omega-3s, low-dose multivitam­ins) after you talk to your doc!
