FDA WARNING_LETTER - Prodose, Inc. - April 29, 2025

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.

Violations include: 1. **Incorrect Active Ingredient Strength:** The strength of doxylamine succinate in the labeling (6.25 mg) does not match the structured product labeling (SPL) basis of strength field ((b)(4)).
