CPAP is the most effective treatment for obstructive sleep apnea, but only when it is used, and many people cannot make it part of their nights. If the mask, the pressure, or the noise has beaten you, you are not out of options. Sleep apnea now has more alternatives than at any point in the past, from custom mouth guards and an implant that moves the tongue to the first medicine approved for the condition. This guide explains the main CPAP alternatives, who each one suits, how they compare, what is being tested now, and how to find a study if CPAP is not working for you.
A different approach to sleep apnea
Excess weight is one of the main drivers of sleep apnea, and new weight loss medicines are being tested to treat both. One study is enrolling adults with moderate to severe apnea and a BMI of 27 or higher.
Before you give up on CPAP
Many reasons people stop using CPAP can be fixed in a single visit: a mask that fits badly, dryness that a humidifier would solve, or pressure that feels too strong and can be adjusted with ramp settings or an auto adjusting machine. Claustrophobia and insomnia respond to treatment too. If you have not had a mask refit or your settings reviewed, it is worth asking your sleep clinic before moving on.
Our guide explains why CPAP may not be working and how each problem is fixed.
But if you have tried and it still does not work, the options below are real alternatives, not second best.
The main alternatives to CPAP
1. Oral appliances (mandibular advancement devices)
A custom mouthpiece, made by a dentist trained in sleep medicine, holds the lower jaw slightly forward during sleep so the airway stays open. Sleep medicine guidelines recommend oral appliances for mild to moderate sleep apnea and as an option for people with any severity who cannot tolerate CPAP. Many people find them far easier to use every night. They are usually less powerful than CPAP in severe apnea, and side effects can include jaw soreness, tooth discomfort, and changes in the bite over time, so a follow-up sleep test is needed to confirm they are working. Over-the-counter mouth guards are not the same and are not recommended for treating apnea.
2. Weight loss and weight loss medicines
Excess weight is one of the main drivers of obstructive sleep apnea, because fat around the neck and tongue narrows the airway. Losing weight can reduce how often breathing stops, and in some people it can make apnea much milder. In December 2024, the FDA approved tirzepatide (Zepbound) as the first medicine for moderate to severe obstructive sleep apnea in adults with obesity, after two trials in 469 adults. It is a weekly injection and is used alongside, or sometimes instead of, other treatments, depending on how much the apnea improves. Our guides cover Zepbound side effects and obesity treatment options.
3. Hypoglossal nerve stimulation (Inspire and similar implants)
A small device implanted under the skin of the chest stimulates the nerve that controls the tongue, moving it forward during sleep so it does not block the airway. You switch it on at night with a remote. The first device, Inspire, was approved in 2014, and more than 120,000 people have received one. Under its current FDA approval, Inspire is for adults with moderate to severe apnea, an apnea hypopnea index (AHI) between 15 and 100, who have tried CPAP without success, with a body mass index (BMI) up to 40. Two newer implants, Genio and Aura6000, are also approved, with narrower ranges. Candidates usually need a sleep endoscopy first, a short procedure under sedation that checks how the airway collapses, because some patterns do not respond.
4. Positional therapy
Some people have apnea mainly when they sleep on their back. For them, wearable devices that vibrate gently when they roll onto their back, or simple positioning aids, can reduce breathing pauses. A sleep study can show whether your apnea is position dependent; if it is not, this approach will not be enough on its own.
5. Surgery
Surgery can widen the airway by removing or reshaping tissue in the throat, treating nasal blockage, removing large tonsils, or, in more extensive procedures, moving the upper and lower jaw forward. Sleep medicine guidelines recommend that adults with a BMI under 40 who cannot tolerate or do not accept CPAP discuss a referral to a sleep surgeon. Results vary a great deal depending on the anatomy, so careful evaluation comes first.
6. Other CPAP style options
If the problem is the pressure rather than the idea of a machine, an auto adjusting machine or a bilevel machine, which uses a lower pressure when you breathe out, can be much easier to tolerate. For some people with mild apnea, small nasal devices that create gentle resistance when breathing out are another option. Your sleep doctor can tell you whether these would be enough in your case.
Which alternative fits you?
The right choice depends mostly on how severe your apnea is, your weight, the shape of your airway, and what you can live with every night. In broad terms, oral appliances and positional therapy suit mild to moderate apnea; nerve stimulation and surgery are considered for moderate to severe apnea when CPAP has failed; and weight loss, including medicine for people with obesity, can help at any severity. Many people combine approaches, such as an oral appliance with weight loss. Whatever you choose, untreated moderate to severe apnea raises blood pressure and the risk of heart disease and stroke, so the goal is a treatment you will actually use, followed by a sleep test to confirm it works.
What is being tested now
Sleep apnea research has never been more active. A pill designed to keep the airway muscles from collapsing during sleep, AD109, is under FDA review, with a decision date of February 28, 2027. Newer weight loss medicines are being tested specifically in people with sleep apnea, and studies are comparing implants with oral appliances and testing new two sided nerve stimulators. Many of these studies are designed for people who could not use CPAP, and some drug studies require that you are not currently using it. Our guide explains how sleep studies work, and our sleep apnea treatment trials page lists what is recruiting.
A study for people with sleep apnea and excess weight
A study of eloralintide, an investigational weight loss medicine from Eli Lilly, is enrolling adults with moderate to severe obstructive sleep apnea and a BMI of 27 or higher. It has two parts: one for people who cannot or prefer not to use CPAP, and one for people who have used CPAP regularly for at least three months. People with diabetes, and those who have taken a weight loss medicine in the past three months, are not eligible, and some participants receive a placebo. Applying takes about 5 minutes, and nothing is decided until you have gone through informed consent.
Common questions
What is the best alternative to CPAP? It depends on your apnea and your body. Oral appliances are the most common alternative for mild to moderate apnea, nerve stimulation is an option for moderate to severe apnea when CPAP has failed, and weight loss helps at any severity. Your sleep doctor can help you choose.
Can sleep apnea be treated without CPAP? Yes. Oral appliances, nerve stimulation implants, positional therapy, surgery, and weight loss, including tirzepatide for people with obesity, can all treat sleep apnea. A follow-up sleep test confirms whether the alternative is working.
Is there a pill for sleep apnea? Not yet for the airway itself. Tirzepatide, a weekly injection, is approved for moderate to severe apnea in adults with obesity, and a pill called AD109 is under FDA review, with a decision expected by February 28, 2027.
Who qualifies for Inspire? Under its current FDA approval, adults with moderate to severe obstructive sleep apnea, an AHI between 15 and 100, who have tried CPAP without success, generally with a BMI up to 40. A sleep endoscopy checks whether your airway is suitable.
Do mouth guards for sleep apnea work? Custom oral appliances made by a dentist can work well for mild to moderate apnea and for people who cannot use CPAP. Over-the-counter mouth guards are not recommended for treating apnea.
Can I join a sleep apnea study if I stopped using CPAP? Often, yes. Many studies are designed for people who could not tolerate CPAP, and some require that you are not using it. Each listing explains its rules.
Do sleep apnea trial participants get paid? Some studies offer compensation for time and travel, and study related care is typically provided at no cost to participants. Compensation varies by trial and is always described during the informed consent process before you agree to anything.
