The U.S. Food and Drug Administration (FDA) has granted expanded approval for the weight loss drug Zepbound to treat obstructive sleep apnea (OSA) in adults with obesity. This groundbreaking decision, announced by drugmaker Eli Lilly, makes Zepbound the first medication approved for addressing this prevalent disorder, which affects around 39 million adults in the United States.
What Is Obstructive Sleep Apnea?
Obstructive sleep apnea occurs when the upper airway becomes blocked during sleep, disrupting airflow and often causing the person to wake up gasping for air. This condition leads to fragmented sleep and is linked to serious health issues, including:
- Diabetes
- Heart arrhythmias
- Heart failure
- Stroke
- Brain damage
Obesity is one of the leading contributors to OSA, as excess weight can narrow the airway. The new approval highlights the role weight loss can play in mitigating this condition.
Current Treatments for Sleep Apnea
Traditionally, OSA has been managed with positive airway pressure (PAP) machines, such as CPAP (continuous positive airway pressure), which work by gently blowing air into the airway to prevent collapse. While effective, these machines can be inconvenient for many patients. Moreover, a 2021 recall of millions of CPAP machines by manufacturer Phillips Respironics has added to patient frustrations.
Zepbound’s Role in Treating Sleep Apnea
Zepbound, which contains the active ingredient tirzepatide (also used in Lilly’s diabetes drug Mounjaro), was already FDA-approved to treat obesity. The recent approval for OSA is based on two clinical trials involving men and women with obesity and moderate to severe sleep apnea. Participants who took Zepbound achieved an average weight loss of 20%, which significantly improved their sleep apnea symptoms.
How Does Zepbound Work?
It remains unclear whether Zepbound’s effectiveness in treating OSA is solely due to weight loss or if tirzepatide has additional mechanisms of action. This approval aligns with a growing body of evidence supporting GLP-1 receptor agonists as transformative drugs for overall health improvement.

GLP-1 Drugs: A Broader Impact
Zepbound’s approval is part of a larger trend showcasing the benefits of GLP-1 drugs, such as Novo Nordisk’s Wegovy, which was recently approved to reduce heart disease risk. Ongoing research is exploring whether these drugs can also help prevent Alzheimer’s disease, curb addiction, and delay kidney disease.
Expert Opinions
Dr. Susan Spratt, Duke Health
Dr. Spratt emphasized the challenges of achieving weight loss without medication, noting that OSA symptoms often improve when patients lose weight. “Weight loss without medication is hard to do,” she said, highlighting Zepbound’s potential to bridge this gap.
Dr. Timothy Morgenthaler, Mayo Clinic
Dr. Morgenthaler, a pulmonologist and sleep medicine specialist, praised CPAP machines for their reliability and affordability but acknowledged the barriers many patients face in using them consistently. Zepbound’s approval offers an alternative for those struggling with traditional treatments.
Implications for Patients and Insurers
Zepbound’s expanded approval may encourage more insurance companies to cover this costly medication, given its dual benefits for weight loss and sleep apnea management. As awareness grows about OSA’s health risks, the availability of a medication-based treatment could drive earlier diagnosis and intervention.
The Connection Between Sleep Apnea and Memory
A recent study presented at the American Academy of Neurology’s annual meeting found that people with sleep apnea are more likely to experience memory and cognitive issues. This underscores the importance of addressing the disorder promptly to prevent long-term complications.
The Road Ahead
Zepbound’s approval marks a significant step forward in the treatment of obstructive sleep apnea. As research continues, it is likely that we will uncover even more ways GLP-1 drugs can improve health outcomes. For the millions of Americans grappling with obesity and sleep apnea, this decision offers new hope for a better quality of life.
FAQs
What is Zepbound?
Zepbound is a weight loss drug containing tirzepatide, a GLP-1 receptor agonist. It has now been approved to treat obstructive sleep apnea in adults with obesity.
How does Zepbound improve sleep apnea?
Zepbound aids in significant weight loss, which reduces airway obstruction. Additional mechanisms of action are still being studied.
Is Zepbound covered by insurance?
Coverage depends on individual insurers, but the expanded approval for OSA may make it more likely to be covered.
Are there side effects to using Zepbound?
Like other GLP-1 drugs, Zepbound may cause nausea, vomiting, or gastrointestinal discomfort. Consult your healthcare provider for detailed information.
Can Zepbound replace CPAP machines?
Zepbound is an alternative for managing OSA, but CPAP machines remain effective and widely used. Your doctor can help determine the best treatment for you.
