For more than a month, Shane Anthony, a 57-year-old auto mechanic, hasn’t been able to get his diabetes medication.

Ozempic, an injection that keeps blood sugar levels in check for patients with type 2 diabetes, has been in shortage for about four months, according to the database maintained by the U.S. Food and Drug Administration, and is backordered at Anthony’s Seattle pharmacy. Without the Novo Nordisk A/S-made prescription, he has suffered recurring dizzy spells while repairing cars. Alternative medications are either out of stock or not covered by his insurance.
