If you read the article title it is not a ban on the drug.
> Ending Use of Oral Phenylephrine as OTC Monograph Nasal Decongestant Active Ingredient
It is a ban on marketing/listing this as an active ingredient on those products. If you read further into the article this is only for oral use and they're requesting comments for nasal use, which would be unaffected by this.
Makes sense. Thank you for clarifying.
