Sleep apnea treatment: your options, who they suit and what the evidence says

The main sleep apnea treatment for moderate to severe obstructive sleep apnea (OSA) is positive airway pressure, usually a CPAP or auto-CPAP machine [1][7]. If that doesn't work for you, proven alternatives include a custom oral appliance, weight loss (including the prescription drug tirzepatide for some adults), positional therapy, an implanted nerve stimulator and surgery [2][3][4][7]. The right choice depends on your severity, anatomy, weight and what you will actually use every night.

This guide explains each option, who it suits and how strong the evidence is. It's for education, not diagnosis. Treatment decisions belong with a sleep physician who has seen your sleep study. Not tested yet? Start with our guide to getting a sleep apnea test.

What are the sleep apnea treatment options?

The table lists the main treatments for adults with OSA, roughly in the order a sleep clinician would consider them.

AASM is the American Academy of Sleep Medicine, whose guidelines most US sleep clinicians follow.

Why is CPAP the first-line treatment for sleep apnea?

CPAP has the most evidence. The AASM's 2019 guideline strongly recommends PAP for adults with OSA and excessive sleepiness [1]. It also suggests PAP when OSA hurts quality of life or comes with high blood pressure [1].

The guideline treats fixed CPAP and auto-adjusting APAP as equally good for ongoing care, and suggests either over bilevel for routine OSA [1]. Head to head, CPAP lowers the apnea-hypopnea index (what AHI means) more than oral appliances or positional therapy [2][11].

For equipment help, see our guides to sleep apnea machines and choosing a CPAP mask.

Why adherence matters as much as the machine

CPAP only works on the nights, and hours, you wear it. The AASM notes that use in the first days to weeks predicts long-term use [1]. People also tend to overestimate their own use, so objective machine data matters [1]. Education, early troubleshooting and remote monitoring all improved adherence in studies [1].

Insurers care too. For Medicare, continued coverage after three months needs a face-to-face re-evaluation. It also needs PAP use of 4 or more hours per night on 70% of nights during a consecutive 30-day period in those first three months [6]. That's at least 21 of 30 nights. Our CPAP usage and adherence guide explains how this is counted.

Mask discomfort, leaks, dryness and pressure that feels too strong are common reasons people quit. Most are fixable with your care team. Never change your prescribed pressure yourself.

What is the best treatment for mild sleep apnea?

Mild OSA (an AHI of 5 to under 15) has more options.

PAP still helps if you have symptoms. The AASM's PAP recommendations are based on sleepiness, quality of life and blood pressure, not on AHI cut-offs alone [1].

Oral appliances are a common alternative for mild or moderate OSA [7]. For mild OSA, one study found no significant difference between CPAP and oral appliances in reaching a target AHI, though evidence was limited [2].

Other options include positional therapy for back-dependent apnea [11] and weight loss. In one long-term cohort, losing 10% of body weight was linked to about a 26% drop in AHI [10]. Mayo Clinic also notes a newer daytime tongue-stimulation device that may help very mild cases, though it doesn't replace CPAP for moderate to severe OSA [7].

Mild doesn't mean ignore it. Our article on whether sleep apnea is dangerous covers the risks.

How can you treat sleep apnea without CPAP?

Good alternatives exist, but each suits a different person.

Oral appliances (mouthguards)

A custom oral appliance moves your lower jaw forward to keep the airway open. The AASM and the American Academy of Dental Sleep Medicine recommend them for adults who can't tolerate CPAP or prefer an alternative [2].

The guideline prefers a custom, titratable device from a qualified dentist over an over-the-counter one, because custom devices lowered AHI more [2]. It also recommends a follow-up sleep test to confirm it works [2]. For severe OSA, CPAP stays first-line [2]. See our guide to sleep apnea devices.

Is there a pill or shot for sleep apnea?

There is now one FDA-approved medicine for OSA, and it's an injection, not a pill. On December 20, 2024, the FDA approved Zepbound (tirzepatide) for moderate to severe OSA in adults with obesity, used with a reduced-calorie diet and more activity [4].

Approval rested on two 52-week trials in 469 adults without type 2 diabetes, one off PAP and one on PAP [4][5]. Average starting AHI was about 50 events per hour [5]. Compared with placebo [5]:

• AHI fell by about 25 events per hour off PAP and 29 on PAP, versus about 5 to 6 with placebo.
• Body weight dropped by about 18% to 20%.
• About 42% to 50% reached an AHI under 5, or 5 to 14 with little daytime sleepiness, versus 14% to 16% on placebo.

Common side effects include nausea, diarrhea, vomiting and constipation, and there are important warnings [4]. Only a prescriber can say if it's right for you. Some people still need treatment after losing weight [7]. Other GLP-1 drugs, such as Ozempic, are not FDA-approved specifically for sleep apnea.

Positional therapy

A vibrating wearable, special pillow or tennis ball sewn into a shirt keeps you off your back [7]. A 2019 Cochrane review found it lowered AHI by about 7 events per hour versus no treatment [11]. CPAP was still better by about 6 events per hour, though people wore positional devices longer [11]. Studies were small and short [11].

Hypoglossal nerve stimulation (Inspire)

This implant, placed in the upper chest, stimulates the nerve that moves your tongue forward as you breathe in [7]. The FDA indication covers adults 22 and older with moderate to severe OSA (AHI 15 to 100) who can't use or tolerate PAP and have no complete concentric collapse at the soft palate [9]. In 2023 the recommended upper BMI rose from 32 to 40 [9].

In the 126-person STAR trial, median AHI fell from 29.3 to 9.0 events per hour at 12 months, a 68% drop [8]. That study had no control group [8].

Sleep apnea surgery options

Surgery is usually considered when other therapies fail or don't fit your life [7]. The AASM's 2021 guideline recommends referring adults who can't use CPAP to a sleep surgeon if BMI is under 40, and to a bariatric surgeon if BMI is 35 or more [3]. With a major blockage like large tonsils, it suggests trying CPAP first [3].

Common procedures include [7]:

• UPPP: removes tissue from the back of the mouth and top of the throat.
• Maxillomandibular advancement: moves both jaws forward to enlarge the airway.
• Nasal surgery, or tonsil and adenoid removal.
• Bariatric (weight-loss) surgery.
• Tracheostomy: reserved for life-threatening cases when nothing else works.

Results vary by procedure and person. Ask how success will be measured, and whether you'll have a sleep test afterward.

Can sleep apnea be cured?

Sometimes, but not for most people.

Apnea can improve a lot, or resolve, when the cause is removed. Weight is the clearest example. In one long-term study, a 10% weight gain was linked to about a 32% rise in AHI, and a 10% loss to about a 26% fall [10]. In the tirzepatide trials, up to about half reached a near-normal or mild, low-symptom level at one year [5].

Surgery can cure apnea when there's one fixable blockage. In children with large tonsils, the American Academy of Pediatrics recommends removing tonsils and adenoids first, with CPAP if apnea persists [14].

But many people still have apnea afterward, and weight regain or aging can bring it back [7]. A repeat sleep test, not just feeling better, is the honest way to know [2]. CPAP, oral appliances and implants treat apnea while you use them. They don't cure it.

How do you treat central sleep apnea?

Central sleep apnea (CSA) is different. The airway isn't blocked; the brain briefly stops signaling you to breathe. It can be linked to heart failure, opioids, high altitude, or appear after starting CPAP.

The AASM's 2025 CSA guideline makes only conditional recommendations, because evidence is limited [13]. Depending on the cause, it suggests CPAP, adaptive servo-ventilation (ASV), bilevel with a backup rate, low-flow oxygen, the medicine acetazolamide, or an implanted phrenic nerve stimulator [13]. It suggests against bilevel without a backup rate [13].

ASV needs special care in heart failure with reduced ejection fraction. The guideline limits it there to experienced centers with close monitoring [13].

If your CPAP data shows many central events, raise it with your clinician. Our guide to central vs. obstructive apneas on CPAP explains those flags.

Can you treat sleep apnea at home?

Home steps support medical treatment. They rarely replace it for moderate to severe OSA.

What has real support:

• Lose weight if you carry extra. Even moderate loss can ease airway narrowing and sleepiness [7][10].
• Exercise about 150 minutes a week [7].
• Limit alcohol and sedatives, which can worsen OSA [7]. Don't stop a prescribed medicine without asking your prescriber.
• Sleep on your side if apnea is worse on your back [7][11].
• Keep your nose clear with saline spray; ask before using decongestants [7].
• Mouth and throat exercises. A 2015 meta-analysis found they cut adult AHI by about 50%, from 24.5 to 12.3, but studies were small and the authors saw them as an add-on [12].

Be cautious with over-the-counter mouthguards, since guidelines prefer custom devices [2]. Mouth taping isn't an approved sleep apnea treatment; ask your clinician first. And less snoring doesn't prove apnea is treated.

How do you know your sleep apnea treatment is working?

Feeling better is a great sign, but check three things.

1. Symptoms. Less daytime sleepiness, fewer morning headaches, and less snoring. Track sleepiness with the Epworth Sleepiness Scale interpreter.

2. Residual AHI. On PAP, your machine estimates events per hour. For oral appliances and surgery, a follow-up sleep test confirms the result [2]. See what a good AHI on CPAP is. Machine-estimated AHI is not a clinical diagnosis.

3. Usage. Watch for slips below about 4 hours a night, the Medicare benchmark [6]. Leaks matter too; see our CPAP leak rate guide.

Apnealytics reads the SD card from ResMed machines (Philips DreamStation 1 and Fisher & Paykel SleepStyle are in testing). It shows nightly AHI, usage, leak and pressure trends in one place. It doesn't diagnose or change treatment, but it makes patterns easy to spot and share.

Contact your care team if you're still sleepy, snoring returns, or your weight changes by 10% or more [7].

The bottom line

The best sleep apnea treatment lowers your AHI, eases your symptoms, and is one you'll use every night. For most adults with moderate to severe OSA, that starts with CPAP, and there are now more proven alternatives than ever.

If you're on CPAP, Apnealytics helps you see whether treatment is doing its job. Upload your SD card, check AHI and usage trends, and bring clear charts to your next appointment. Free and Pro plans are available.

Frequently asked questions

What is the most effective treatment for sleep apnea?

For moderate to severe obstructive sleep apnea, CPAP or auto-CPAP has the strongest evidence. It lowers AHI more than oral appliances or positional therapy [1][2][11]. But effectiveness depends on use, and a treatment you wear all night may beat a stronger one you abandon. Your sleep physician can help you weigh both.

Can sleep apnea go away on its own?

Usually not without a change in its cause. Significant weight loss can lower AHI, and some people reach a normal or mild level [5][10]. Surgery can resolve apnea when there's one fixable blockage, like large tonsils in children [14]. Many people still need ongoing treatment, so a repeat sleep test is the best way to know [2].

Is there a pill for sleep apnea?

Not yet. The only FDA-approved medicine for obstructive sleep apnea is tirzepatide (Zepbound), an injection approved in December 2024 for adults with moderate to severe OSA and obesity [4]. It works mainly through weight loss and is used with diet and exercise [4]. Other weight-loss drugs aren't approved specifically for sleep apnea.

What is the best sleep apnea treatment without CPAP?

It depends on you. A custom oral appliance suits many people with mild to moderate OSA [2]. Tirzepatide is an option for adults with obesity [4]. Inspire suits some people with moderate to severe OSA who can't use PAP [9]. Positional therapy helps back-dependent apnea [11], and surgery may help selected people [3].

Does insurance cover sleep apnea treatment?

Often, but rules vary. For Medicare, ongoing CPAP coverage after three months requires a doctor's re-evaluation and use of 4 or more hours a night on 70% of nights in a 30-day stretch [6]. Coverage for oral appliances, implants, surgery and medicines differs by plan, so check with your insurer first.

How long does it take for sleep apnea treatment to work?

CPAP can cut breathing events from the first night it's used well, though comfort and benefits often build over weeks. The AASM notes early use predicts long-term use, so the first weeks matter [1]. Weight-loss approaches take much longer; the tirzepatide trials measured results at 52 weeks [5].
