The most effective treatment for sleep apnea depends on what type you have and what’s causing it. For most people with obstructive sleep apnea (the most common form), a CPAP machine remains the gold standard. But it’s not the only option. Oral appliances, positional devices, medications, and lifestyle changes can all play a role, sometimes on their own and sometimes alongside CPAP.
CPAP and Oral Appliances
Continuous positive airway pressure (CPAP) delivers a steady stream of air through a mask to keep your airway open while you sleep. It reduces breathing interruptions more effectively than any other single treatment. Meta-analyses consistently show CPAP is significantly better at lowering the number of apnea and shallow-breathing events per hour (called the apnea-hypopnea index, or AHI) compared to other approaches.
The catch is that many people struggle to wear CPAP consistently. The mask can feel claustrophobic, cause dry mouth, or just be uncomfortable enough that it ends up in a drawer. If that sounds familiar, a mandibular advancement device (MAD) is worth considering. These custom-fitted oral appliances push your lower jaw slightly forward to open the airway. They don’t reduce breathing events as dramatically as CPAP, but people tend to use them more consistently, which can make the real-world benefit comparable. MADs work best for mild to moderate sleep apnea.
Tirzepatide: The First FDA-Approved Medication
In a landmark decision, the FDA approved tirzepatide (sold as Zepbound) as the first medication specifically indicated for obstructive sleep apnea. It’s approved for adults with moderate to severe OSA who also have obesity, and it’s meant to be used alongside a reduced-calorie diet and increased physical activity.
The approval was based on two placebo-controlled studies involving 469 adults. After 52 weeks of treatment, participants taking tirzepatide had significantly fewer breathing interruptions per hour compared to placebo. Greater proportions of people on the medication achieved remission or dropped to mild sleep apnea with symptoms resolved. The drug works primarily through weight loss: excess weight, especially around the neck and upper airway, is one of the strongest drivers of obstructive sleep apnea. Losing even 10% of body weight can substantially reduce the severity of the condition, and tirzepatide helps achieve that.
Positional Therapy Devices
If your sleep apnea is significantly worse when you sleep on your back (which is true for a large subset of people), positional therapy can be surprisingly effective. Vibrotactile devices are small wearable gadgets that gently vibrate when you roll onto your back, nudging you to shift positions without fully waking you up.
A meta-analysis published in Thorax found these devices reduced the time spent sleeping on your back by about 70% and cut breathing events by roughly 43% overall. For people with mild positional sleep apnea, back-sleeping time dropped by 64%. For moderate to severe cases, it dropped by 71%. These aren’t a replacement for CPAP in severe sleep apnea, but for position-dependent cases, they can make a meaningful difference on their own or combined with other treatments.
Nasal Sprays for Sleep Apnea With Congestion
If you have chronic nasal congestion or allergies alongside your sleep apnea, a steroid nasal spray may help. A randomized, placebo-controlled study tested fluticasone (a common nasal corticosteroid) in patients who had both snoring-related sleep apnea and rhinitis. After four weeks, the group using fluticasone had significantly fewer breathing events per hour compared to placebo. In people with confirmed sleep apnea, the median reduction was about 6.5 fewer events per hour.
Nasal sprays won’t cure sleep apnea on their own, but if nasal congestion is contributing to your airway obstruction, treating it can reduce severity and also make CPAP more comfortable to use.
Treatments for Central Sleep Apnea
Central sleep apnea is a different condition where your brain intermittently fails to signal your muscles to breathe. It’s less common than the obstructive type and requires a different approach. One medication that has shown benefit is acetazolamide, a mild diuretic that stimulates breathing by slightly acidifying the blood. This shifts the threshold at which your body triggers a breath, making it less likely that breathing will pause during sleep.
Acetazolamide is particularly well-studied for central sleep apnea caused by high altitude or heart failure. In a double-blind, placebo-controlled crossover study of patients with severe heart failure, a dose taken 30 minutes before bedtime significantly improved both the number of breathing pauses and blood oxygen levels during sleep. It’s typically prescribed as a nightly dose at bedtime, though the specifics vary by individual.
What About Supplements?
You’ll find claims online that magnesium, vitamin D, or melatonin can treat sleep apnea. The evidence is thin. People with sleep apnea do tend to have lower magnesium levels, and correcting low magnesium has been shown to improve inflammation and oxidative stress markers related to poor sleep quality. But no clinical trial has demonstrated that magnesium supplementation meaningfully reduces the number of breathing events during sleep.
The same is true for vitamin D. Deficiency is common in people with sleep apnea, but that doesn’t mean supplementing it fixes the underlying airway problem. These supplements may support general sleep quality and overall health, but they shouldn’t be relied on as a primary treatment for sleep apnea.
Alcohol and Sleep Apnea Severity
What you avoid taking can matter as much as what you take. Alcohol relaxes the muscles in your throat, which worsens airway collapse during sleep. One study estimated that for every alcoholic drink consumed per day, there was a 25% increased odds of at least mild sleep-disordered breathing in men. Even moderate drinking in the evening can turn mild sleep apnea into something noticeably worse, increasing both the frequency and duration of breathing pauses overnight. Cutting back on alcohol, especially in the hours before bed, is one of the simplest ways to reduce severity.
Choosing the Right Approach
The right treatment depends on several factors: the type of sleep apnea you have (obstructive vs. central), how severe it is, whether it’s position-dependent, and whether weight or nasal congestion plays a role. For many people, the answer isn’t a single treatment but a combination. Someone with moderate obstructive sleep apnea, obesity, and nasal congestion might benefit from CPAP, a weight-loss medication, and a nasal steroid spray all working together.
Mild cases, especially position-dependent ones, may respond well to a positional device or an oral appliance alone. Severe cases almost always need CPAP or a similar airway pressure device as the foundation, with other treatments layered on to improve comfort and outcomes. A sleep study is the starting point for any of these decisions, since the specific pattern of your breathing events during sleep determines which treatments are most likely to help.
