This FDA Warning Letter, dated March 28, 2025, addresses Spirit Pharmaceuticals LLC (now Prodose, Inc.) regarding drug listing violations for their product, Maximum Strength Nighttime Severe Cold and Flu, NDC 68210-4210.
The FDA previously communicated these issues on March 30, 2023, and again via a deficiency letter on December 30, 2024, and a data removal notification on February 13, 2025, due to continued deficiencies.
