The US Food and Drug Administration approved the type 2 diabetes drug tirzepatide for use in chronic weight management Wednesday (Thursday AEDT), making official the use of a medicine already widely prescribed off-label for weight loss.
“Obesity and overweight are serious conditions that can be associated with some of the leading causes of death such as heart disease, stroke and diabetes,” Dr John Sharretts, the FDA’s director of the Division of Diabetes, Lipid Disorders, and Obesity, said in the FDA’s news release. “In light of increasing rates of both obesity and overweight in the United States, today’s approval addresses an unmet medical need.”
The main side effects of Zepbound are gastrointestinal issues such as nausea, vomiting, constipation and diarrhoea, the FDA said. The drug’s label will contain warnings for inflammation of the pancreas, gallbladder problems, low blood sugar, acute kidney injury, diabetic retinopathy, or damage to the eye’s retina, in patients with type 2 diabetes mellitus and suicidal behavior or thinking.

Lilly specifically highlighted in its release that Zepbound costs 20 per cent less than semaglutide for weight loss.
Lilly said in the US it would offer a savings card for patients with commercial insurance to be able to get the drug for $US25 for a one- or three-month prescription, if patients’ plans cover the medicine; if their plan doesn’t cover Zepbound, the savings card would allow them to pay $US550 for a one-month prescription.
“Far too many hurdles continue to prevent people living with obesity from accessing obesity treatments that could lead to significant weight loss,” Mike Mason, president of Lilly Diabetes and Obesity, said in the company’s release. “Broader access to these medicines is critical, which is why Lilly is committed to working with healthcare, government and industry partners to ensure people who may benefit from Zepbound can access it.”
