The FDA is warning Americans about the risk of overdosing on weight loss drugs Ozempic and Wegovy. The agency says doses of the drugs are often miscalculated by users or health care providers, by drawing too much from a multi-dose vial. Symptoms of overdose can including nausea, vomiting, headache, abdominal pain, and lead to acute pancreatitis or gallstones. Do you know anyone who's using Ozempic or similar drugs?
