Congestion as a barrier to CPAP and appliance tolerance

Nasal congestion is associated with difficulty tolerating CPAP and oral-appliance therapy. Addressing the nasal airway is a non-competing adjunct that may help patients stay on the therapy you have prescribed. Allermi does not treat sleep apnea and does not compete with PAP or appliances.

Peer-reviewed anchors

What the literature shows.

Combination therapy

Nasal resistance and CPAP failure

Sugiura 2007, Saitama Medical University · Clinical study

Each 0.1 Pa/cm³/s increase in nasal resistance was associated with 1.48x higher odds of CPAP failure. Association, not an Allermi outcome.

Combination therapy

Nasal treatment and CPAP acceptance (as cited internally)

Camacho 2015 · Meta-analysis

Improved CPAP acceptance following nasal treatment in the pooled data. Establishes the nasal airway as a recognized lever in the literature.

Micro-dosed decongestant

Intranasal corticosteroid plus oxymetazoline restoring PAP tolerance (case report)

Anokwute 2025, JCSM · Case report

A published case in which intranasal corticosteroid plus oxymetazoline restored PAP tolerance, closely matching Allermi's formulation. Presented as a case report, not proof of population effect.

Allermi data, observational

Real-world patient-reported outcomes.

95.5%

of 7,087 patients reporting nasal congestion reported improvement (AAAAI abstract; chi-square p < 0.0001; all symptoms significant except snoring).

96.6%

of 1,810 patients reporting sleep disruption reported improvement (AAAAI abstract, observational; p < 0.0001). Snoring did not reach significance.

These data are observational and are presented as supplementary to the peer-reviewed evidence above.

On framing

Nasal congestion is associated with difficulty tolerating CPAP and oral-appliance therapy. Allermi does not treat sleep apnea and is not a substitute for prescribed sleep therapy.

Patient voices

In their words.

My symptoms have significantly improved and I've been able to use my CPAP more often and for a much longer duration.
Andrew D. · Verified review
I use a CPAP at night, and my breathing has improved. The average number of apnea episodes has decreased, and I'm sleeping through the night.
