Can't tolerate CPAP?You still have options

CPAP is the first-line treatment for moderate-to-severe obstructive sleep apnea, and it works well for many people. But not everyone tolerates it, and not every case requires it. If you've tried CPAP and can't get comfortable — or you want to understand your options before you start — there are established alternatives worth discussing with a physician.

Before abandoning CPAP entirely, it's worth troubleshooting: mask fit, pressure, and humidification problems are common and often fixable. When CPAP still isn't right, the options below may apply. The correct choice depends on the type and severity of your apnea, which is why it's guided by your sleep test results and physician judgment — not a one-size-fits-all rule.

Excess weight is a major, modifiable driver of obstructive sleep apnea, and weight loss can meaningfully reduce its severity. For patients with obesity, this is often the highest-leverage place to start — and it now includes a medication option.

Our physicians can prescribe Zepbound (tirzepatide) — a once-weekly injection that, in December 2024, became the first medication the FDA approved specifically for obstructive sleep apnea in adults who also carry extra weight. In a year-long study (the SURMOUNT-OSA trial, New England Journal of Medicine, 2024), people lost about 18–20% of their body weight and, on average, cut the pauses in breathing that define sleep apnea by more than half — often easing daytime tiredness and, for some, reducing how much they rely on CPAP.

Zepbound isn't right for everyone, and weight management is usually combined with — not a replacement for — active apnea treatment while the weight changes take effect. A physician reviews your sleep test results, health history, and candidacy to decide whether it fits your plan. For a deeper look at the trial data, insurance coverage, and how to sequence GLP-1s with CPAP, see our guide to GLP-1s and sleep apnea.

BiPAP delivers two pressure levels — higher when you breathe in, lower when you breathe out — which some people find easier to tolerate than the single pressure of CPAP. A physician may consider BiPAP when you struggle with CPAP pressure, need higher pressures, or have certain breathing patterns. Because it's still positive airway pressure, it requires a prescription and a valid diagnosis. See our CPAP and BiPAP prescription page for how this works.

An oral appliance is a custom-fitted dental device, worn during sleep, that holds the lower jaw slightly forward to keep the airway open. The American Academy of Sleep Medicine recommends oral appliance therapy for adults with mild to moderate obstructive sleep apnea and for those who cannot tolerate CPAP. Appliances are fitted by a qualified dental sleep medicine provider, so a sleep physician provides a referral and continues to oversee your care.

Some people have positional sleep apnea — breathing events that happen mainly when sleeping on the back. In these cases, strategies or devices that keep you off your back can reduce events. Positional therapy is usually a complement to other treatment rather than a standalone cure, and its role depends on what your sleep study shows.

There's no universal "best" alternative — the right treatment depends on your apnea type and severity, your anatomy, other health conditions, and how you responded to previous therapy. That's a clinical decision made with a board-certified sleep physician using your test data.

If you haven't been diagnosed yet, start with a home sleep test. For the full picture of how diagnosis and treatment fit together, see our sleep apnea treatment guide.
