Thanks to Kipp Ellsworth for this link: FDA Announcement Regarding Medical Product Shortages Related to Puerto Rico Production

An excerpt: the hurricane disrupted Baxter’s amino acids production facilities in Puerto Rico; Baxter is one of the largest manufacturers of this product serving the U.S. market. In order to help mitigate this shortage, the FDA has worked with Baxter to facilitate the temporary importation of amino acids for pediatric and adult formulations of IV amino acids from Baxter facilities in the United Kingdom and Italy.
