Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial tests whether chewing sugar-free gum for 20 minutes, alongside standard intravenous medication, can reduce dizziness and nausea in adults with a common inner-ear condition called posterior canal BPPV. Participants are randomly assigned to either chew gum or receive standard treatment alone, with symptom severity measured before and after. The idea is that chewing may stimulate nerve pathways that help calm the vestibular system, potentially offering a simple, drug-free boost to standard care.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Chewing gum (sugar-free, mint-flavored) added to standard intravenous dimenhydrinate treatment
What this could lead to
If chewing gum helps, it could offer a simple, drug-free way to ease dizziness and nausea during BPPV attacks, potentially reducing reliance on sedating medications.
What could go wrong
This is a small, early-stage trial, and the effect may be modest or not clinically significant. Chewing gum might not work for everyone, and the study only measures short-term symptom changes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Aged 18-65 years * Duration of dizziness complaint less than 24 hours * Posterior canal BPPV diagnosis confirmed by the emergency physician via the Dix-Hallpike test * Intravenous administration of 50 mg dimenhydrinate in 100 cc 0.9% NaCl initiated by the responsible emergency physician * Symptomatic dizziness with VAS ≥ 4 * Alert, cooperative, and able to chew gum * Willingness to participate and provision of written informed consent Exclusion Criteria: * Findings suggestive of central vertigo (vertical nystagmus, diplopia, ataxia, hemiparesis, focal neurological deficit, etc.) * Pregnancy * Known gum intolerance, history of allergy to gum or its excipients, temporomandibular joint dysfunction, significant tooth loss, use of dentures or removable prosthetics that would prevent chewing * Altered level of consciousness * Central pathology detected on investigations performed during the visit * Hemodynamic and/or respiratory instability * Diagnosis other than posterior canal BPPV as the cause of vertigo * Treatment other than pharmacological therapy planned or already administered by the responsible emergency physician * Active vomiting at the time of enrollment * Severe dizziness with VAS ≥ 8 (excluded due to high likelihood of requiring additional treatment, risk of protocol deviation, and safety concerns regarding gum chewing) * Patients who initially consented but subsequently wish to withdraw from the study
