ASCOR® (Ascorbic Acid Injection, USP) — Product Availability Update

Updated: 10/21/2025

McGuff Pharmaceutical, Inc. is committed to returning ASCOR® (Ascorbic Acid Injection, USP) to the U.S. market as soon as possible. We are actively coordinating with the U.S. Food and Drug Administration (FDA) and our supply partners to complete the remaining steps necessary for product release.

At this time, product release timing has not been finalized. Several factors continue to influence availability, including supply chain conditions and FDA lot-release processes. Because some of these factors are external to McGuff, timelines may change without prior notice.

Please be assured that restoring the ASCOR supply remains our highest priority. All McGuff employees are working diligently to ensure that when ASCOR returns to the market, it meets the quality, safety and reliability standards expected by both customers and regulators.

We understand the importance of this medication to patients and healthcare providers and we appreciate your continued patience and understanding.

We will provide additional updates as soon as more definitive information becomes available.
