1 in 3 Pregnant Women Can't Breathe Through Their Nose — and Most Treatments Are Off-Limits
Pregnancy rhinitis affects roughly 30% of expectant mothers, typically arriving in the second trimester and lasting until delivery. Hormonal shifts cause nasal blood vessels to swell, mucus production increases, and suddenly every night is a battle between your blocked nose and the sleep you desperately need.
Here's the cruel catch: the most effective treatments — nasal steroid sprays and oral decongestants — carry safety concerns during pregnancy. Most belong to FDA Pregnancy Category C, meaning animal studies have shown fetal harm and there are insufficient human trials to confirm safety.
Intranasal triamcinolone was associated with a 2.71× increased risk of respiratory tract defects in a large population-based cohort study. Oral decongestants have associations with cardiac, ear, and limb abnormalities in the first trimester.
— Bérard et al., J Allergy Clin Immunol (2016); Medical Management of Rhinitis in Pregnancy, ScienceDirect (2022)So most mothers-to-be are told: "Just deal with it." Use saline rinse. Elevate your pillow. Wait it out. But pregnancy congestion isn't just discomfort — it disrupts the deep sleep that's critical for fetal development, maternal recovery, and emotional wellbeing.

Nasal Steroids vs. SONU: A Safety Comparison
Every pregnant woman facing congestion is forced into a risk-benefit calculus that shouldn't be necessary. Here's how the options compare:
| Nasal Steroids | SONU | |
|---|---|---|
| Drug category | ⚠ Category B–C (most are C) | ✓ No drugs whatsoever |
| Fetal risk | ⚠ "Cannot rule out possibility of harm" — FDA label language for budesonide | ✓ Zero pharmacological exposure to fetus |
| Triamcinolone | ✗ 2.71× risk of respiratory defects (Bérard 2016) | ✓ Not applicable — no systemic absorption |
| Clinical trial | ⚠ "Lacking sufficient clinical trials in pregnancy" — Alhussein et al. (2017) | ✓ Pivotal trial did NOT exclude pregnant women; no adverse events reported |
| Side effects | ⚠ Nosebleed, nasal irritation, sore throat | ✓ None reported across all clinical trials |
| Mechanism | Suppresses immune/inflammatory response | Acoustic vibration promotes natural vasoconstriction + mucociliary clearance |
Key safety distinction: SONU's randomized controlled trial, published in the International Forum of Allergy & Rhinology, did not exclude pregnant participants. Among all women in the trial — including those with pregnancy-related rhinitis — zero adverse events were reported.

How SONU Works — and What the Research Shows
SONU uses your phone's camera to map your unique sinus anatomy, then delivers personalized acoustic resonance therapy through a comfortable headband. Gentle vibrations at your sinuses' specific resonant frequencies promote natural decongestion — no chemicals enter your body.

The mechanism works through vasoconstriction (reducing nasal tissue swelling), sonication (thinning mucus), and mucociliary clearance (natural drainage) — all without introducing any substance into the body. Acoustic vibration associated with humming has been shown to modulate autonomic inputs to the nasal mucosa and enhance nitric oxide activity, which may exert a natural decongestant and anti-inflammatory effect.
Your new bedtime ritual
Three Steps. 15 Minutes. No Medication.
1
Scan Your Face
The SONU app maps your sinus anatomy via your phone camera to calculate your personalized resonant frequencies.
2
Wear & Relax
Place the soft headband on your forehead. Close your eyes as soothing vibrations gently open your nasal passages. Many moms describe it as spa-like and calming.
3
Breathe & Sleep
Remove the band and breathe freely through your nose. Fall asleep knowing you and your baby are completely safe.
