This study aims to investigate efficacy of two different intravenous drugs (dimenhydrinate and piracetam) in the symptomatic management of peripheral vertigo.

The patients will be randomized in two groups according to symptomatic treatment modalities: Dimenhydrinate (100 mg) and piracetam (2 g) will be given in 100 cc normal saline in 30 minutes. Each patient will be asked if her/his vertigo symptoms resolved or not, according to a numeric rating scale (0=no vertigo, 10=worst possible vertigo). The patient will be rate the intensity of symptoms in the following times:

  • Numeric rating scale (1 to 10): Admission
  • Numeric rating scale (1 to 10): After the study drug (No ambulation)*
  • Numeric rating scale (1 to 10): After the study drug (Ambulation)*

    • Ambulation refers to head movements or walking in the room, if applicable.
