NO WORD ON IF IT’S MADE IN CHINA, BUT I HAVE MY SUSPICIONS: Diabetes Drug Januvia Contaminated with Carcinogen. “The FDA said that it allows 37 nanograms per day of nitrosamine in a drug, but to avoid any shortages of the diabetes medications, it is allowing up to 246.7 nanograms daily.

Januvia is the third best-selling drug for Merck, followed by Janumet, with revenues of $3.3 billion and nearly $2 billion, respectively, in 2021 for the company, Bloomberg said.”
