Nasal Strips
External adhesive strips mechanically pull parts of the nose outward and may make nasal breathing feel easier for some people.

Nasal Dilators
Internal and external dilators use mechanical support to widen or stabilize portions of the nasal airway.

Nasal products may help some people breathe more comfortably, but they aren't a stand-alone treatment for sleep apnea.

How nasal strips work
Nasal strips are adhesive bands placed across the outside of the nose. Their spring-like structure applies an outward force that can help open the nasal valve region.
They don't remove mucus or treat every cause of nasal inflammation. Their primary action is mechanical.
What the evidence says
Research suggests that nasal dilators can improve aspects of nasal airflow for some people. However, systematic reviews have not found them to be an effective stand-alone treatment for obstructive sleep apnea.
What nasal strips may help with
- Subjective nasal airflow
- Nasal valve-related restriction
- The sensation of nasal congestion
- Breathing comfort during exercise or sleep for some people
What they don't do
- Correct a deviated septum
- Cure allergies
- Remove nasal inflammation
- Replace treatment for obstructive sleep apnea

SLEEP
Snoring isn't always just a nose problem
Nasal strips may make nasal breathing easier for some people, but snoring can have many different causes.
Persistent or disruptive snoring can sometimes occur alongside obstructive sleep apnea.
When to talk to a healthcare professional
Consider getting evaluated if snoring is accompanied by witnessed pauses in breathing, gasping or choking during sleep, significant daytime sleepiness, or major sleep disruption.

Nasal dilator classification
FDA classifies nasal dilators under product code LWF as Class I devices with the applicable 510(k)-exempt classification, subject to exemption limitations.
FDA classification →Systematic review & meta-analysis
A 2026 systematic review and meta-analysis covering 17 studies and 496 participants found no significant overall improvement in several objective sleep-disordered breathing outcomes from nasal dilators.
Read the study →Nasal dilators & OSA
A systematic review found that nasal dilators can improve subjective nasal breathing but did not demonstrate significant improvement in important obstructive sleep apnea outcomes.
Read the review →Nasal strips & congestion
Clinical research has found improvements in selected subjective congestion and sleep measures in people using certain nasal strips.

Frequently asked questions
Do nasal strips treat sleep apnea?
No. Current evidence does not support nasal dilators as a stand-alone treatment for obstructive sleep apnea.
Can nasal strips help congestion?
They can mechanically widen portions of the nasal passage, and some studies report improvements in subjective congestion or sleep measures. They do not treat every cause of congestion.
Are nasal strips FDA approved?
Be careful with this wording. FDA classifies certain nasal dilator products as Class I devices. FDA classification, registration, or listing should not automatically be described as individual FDA approval.
When should I get medical advice?
Persistent nasal obstruction, significant breathing difficulty, frequent disruptive snoring, or symptoms suggestive of sleep apnea are reasons to consider discussing the issue with a healthcare professional.
