Emergency Department Visits for Adverse Events Related to Dietary Supplements.

BACKGROUND: Dietary supplements, such as herbal or complementary nutritional products and micronutrients (vitamins and minerals), are commonly used in the United States, yet national data on adverse effects are limited. METHODS: We used nationally representative surveillance data from 63 emergency departments obtained from 2004 through 2013 to describe visits to U.S. emergency departments because of adverse events related to dietary supplements. RESULTS: On the basis of 3667 cases, we estimated that 23,005 (95% confidence interval [CI], 18,611 to 27,398) emergency department visits per year were attributed to adverse events related to dietary supplements. These visits resulted in an estimated 2154 hospitalizations (95% CI, 1342 to 2967) annually. Such visits frequently involved young adults between the ages of 20 and 34 years (28.0% of visits; 95% CI, 25.1 to 30.8) and unsupervised children (21.2% of visits; 95% CI, 18.4 to 24.0). After the exclusion of unsupervised ingestion of dietary supplements by children, 65.9% (95% CI, 63.2 to 68.5) of emergency department visits for single-supplement-related adverse events involved herbal or complementary nutritional products; 31.8% (95% CI, 29.2 to 34.3) involved micronutrients. Herbal or complementary nutritional products for weight loss (25.5%; 95% CI, 23.1 to 27.9) and increased energy (10.0%; 95% CI, 8.0 to 11.9) were commonly implicated. Weight-loss or energy products caused 71.8% (95% CI, 67.6 to 76.1) of supplement-related adverse events involving palpitations, chest pain, or tachycardia, and 58.0% (95% CI, 52.2 to 63.7) involved persons 20 to 34 years of age. Among adults 65 years of age or older, choking or pill-induced dysphagia or globus caused 37.6% (95% CI, 29.1 to 46.2) of all emergency department visits for supplement-related adverse events; micronutrients were implicated in 83.1% (95% CI, 73.3 to 92.9) of these visits. CONCLUSIONS: An estimated 23,000 emergency department visits in the United States every year are attributed to adverse events related to dietary supplements. Such visits commonly involve cardiovascular manifestations from weight-loss or energy products among young adults and swallowing problems, often associated with micronutrients, among older adults.

Scientific and Regulatory Perspectives in Herbal and Dietary Supplement Associated Hepatotoxicity in the United States.

In the United States (US), the risk of hepatotoxicity linked to the widespread use of certain herbal products has gained increased attention among regulatory scientists. Based on current US law, all dietary supplements sold domestically, including botanical supplements, are regulated by the Food and Drug Administration (FDA) as a special category of foods. Under this designation, regulatory scientists do not routinely evaluate the efficacy of these products prior to their marketing, despite the content variability and phytochemical complexity that often characterizes them. Nonetheless, there has been notable progress in the development of advanced scientific methods to qualitatively and quantitatively measure ingredients and screen for contaminants and adulterants in botanical products when hepatotoxicity is recognized.

Procedures and lifestyle changes that can enhance the lives of diabetic patients.

This article emphasizes to primary care physicians the importance of maintaining a diabetic patient's blood sugar level within the normal range. Additionally, it aims to impress on those who care for diabetic patients some of the adverse consequences of surgical and dental procedures that can be avoided by proper precautionary measures taken before the procedures.

Herbal products and supplemental nutrients used in the management of diabetes.

As companies, including large pharmaceutical houses, try to market supplemental nutrients and herbal products to ever-increasing numbers of consumers, diabetics will start to approach their physicians about these alternative remedies. A whole new industry know as "neutraceuticals" has evolved. This new industry is a combination of the vitamin supplement and herbal industries trying to work with regulatory agents to develop good manufacturing processes to ensure that consumers obtain good products. In fact, some diabetics may be taking herbal or nutritional supplements without their physician's knowledge. Therefore, it is important to query diabetic patients at least once a year as to whether they are using any herbal or nutritional products. Once it is determined that a patient is using these products, physicians must decide if they or someone else should address the issue of taking these products. Physicians who have a good comfort level with herbal products by all means should recommend them to their patients. If such a comfort level is lacking or low, patients can be referred for a consultation on the use of supplements or told that information will be forwarded to them after contact is made with someone who has knowledge of diabetes and use of appropriate supplements. This article reviews nine nutrient and herbal remedies commonly used for diabetes to facilitate such patient education.
