Goering called Morell Der Reichsspritzenmeister, a nickname that stuck. This term does not have a precise English translation. Among the translations of this nickname are "Injection Master of the German Reich", or Reichmaster of Injections "The Reich's Injections Impresario" (Junge, Until the Final Hour), and "The Master of the Imperial Needle" (O'Donnell, The Bunker). When this term is translated, its underlying meaning is the same - it implied that Morell always resorted to using injections and drugs when faced with a medical problem, and that he overused these drug injections.

After the 20 July 1944 assassination attempt against Hitler, Morell treated him with topical penicillin, which had only recently been introduced into testing by the U.S. Army. Where he acquired it is unknown, and Morell claimed complete ignorance of penicillin when he was interrogated by American intelligence officers after the war. When members of Hitler's inner circle were interviewed for the book The Bunker, some claimed Morell owned a significant share in a company fraudulently marketing a product as penicillin.

By April 1945, Hitler was taking 28 different pills a day, along with numerous injections (including many of glucose) every few hours and intravenous injections of methamphetamine almost every day.[citation needed]

On 22 April 1945, about a week before committing suicide, Hitler dismissed Morell from the Führerbunker in Berlin, saying that he did not need any more medical help. Morell left behind a large amount of prepared medicine; during the last week of Hitler's life, they were administered by Dr. Werner Haase and by Heinz Linge, Hitler's valet.
