TOPLINE:
The estimated number of US adults who consumed at least one of the six most frequently reported hepatotoxic botanicals in the last 30 days is similar to the number of patients prescribed potentially hepatotoxic drugs, including nonsteroidal anti-inflammatory drugs (NSAIDs) and simvastatin.
METHODOLOGY:
- Herbal and dietary supplements (HDS) are an increasingly common source of drug hepatotoxicity cases, but their prevalence and the reasons for their use among the general population are uncertain.
- This survey study evaluated nationally representative data from 9685 adults (mean age, 47.5 years; 51.8% women) enrolled in the National Health and Nutrition Examination Survey (NHANES) between January 2017 and March 2020.
- Participants reported their use of HDS and prescription drugs through personal interviews for a 30-day period prior to the survey date.
- Researchers compared the clinical features and baseline demographic characteristics of users of six potentially hepatotoxic botanicals (ie, turmeric, green tea, Garcinia cambogia, black cohosh, red yeast rice, and ashwagandha) with that of nonusers.
- The prevalence of use of these at-risk botanicals was compared with that of widely prescribed potentially hepatotoxic medications, including NSAIDs, simvastatin, and sertraline.
TAKEAWAY:
- In the cohort of 9685 participants, 4.7% of individuals reported consumption of at least one of the six potentially hepatotoxic botanicals in the past 30 days, with turmeric being the most common, followed by green tea.
- Extrapolating the survey data, researchers estimated that 15.6 million US adults use at least one of these six botanicals, which is comparable to the number of those prescribed potentially hepatotoxic drugs, including NSAIDs (14.8 million) and simvastatin (14.0 million). Sertraline use was lower (7.7 million).
- Most individuals used these botanicals without the recommendation of their healthcare provider.
- Those using botanicals were more likely to be older (adjusted odds ratio [aOR], 2.36; P = .04 for 40-59 years; aOR, 3.96; P = .001 for ≥ 60 years), to have some college education (aOR, 4.78; P P
- The most common reasons for using any of these six potential hepatotoxic botanicals were to improve or maintain health or to prevent health problems or boost immunity.
IN PRACTICE:
“In light of the lack of regulatory oversight on the manufacturing and testing of botanical products, it is recommended that clinicians obtain a full medication and HDS use history when evaluating patients with unexplained symptoms or liver test abnormalities,” the authors wrote.
SOURCE:
The study, led by Alisa Likhitsup, MD, MPH, Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan, was published online on August 5 in JAMA Network Open.
LIMITATIONS:
The survey response rate was low at 43.9% for adults aged ≥ 20 years. As NHANES is a cross-sectional study, the causal relationship between consumption of the six botanicals of interest and the development of liver injury could not be determined. The use of HDS products and medications was self-reported in NHANES and not independently verified using source documents.
DISCLOSURES:
This study did not report any source of funding. Two authors declared receiving grants from pharmaceutical companies outside the submitted work.
