Market view

5 marketed package NDCs · 2 active manufacturers
Same drug class
Other molecules FDA puts in HER2/neu Receptor Antagonist, with whether each is in shortage right now. Same class is not the same drug — substitution is a clinical decision, and this is a supply picture, not a recommendation.
Common questions
- Is Trastuzumab-anns in shortage right now?
- No. FDA does not currently list Trastuzumab-anns in shortage. This page is rebuilt every morning from FDA's shortage database, so a new posting appears here the day it is published.
- Who makes Trastuzumab-anns?
- 2 companies have marketed Trastuzumab-anns in the last 30 days, according to the FDA NDC Directory. That is a thin market — if one stops making it, supply is at risk quickly. Every manufacturer and package is listed on this page.
