47 people nationwide suffer from kidney damage after ingesting products containing red yeast rice. Approximately 90% are between the ages of 40 and 69, and nearly 70% are women.
The earliest patient to receive a medical examination was November last year, and 80% of the patients visited the hospital after January this year. No deaths have been reported so far. The Japanese Society of Nephrology has been conducting a survey of its member doctors for the past day to see if any patients have experienced impaired kidney function after taking the three types of Kobayashi Pharmaceutical products.
