Mr Trank is a 55 year old male who has requested an appointment for assessment of ongoing dizzy spells for approximately two weeks. More detailed discussion reveals Mr Trank usually wakes with a sensation of the world spinning which progresses through the day. He denies any hearing loss, tinnitus or problems with balance/co-ordination. Apart from a mild upper respiratory tract infection a month ago, he is normally fit and well and has no regular medication. Examination reveals fine horizonal nystagmus but otoscopy examination and systems examination is otherwise unremarkable. A clinical diagnosis of Vestibular Neuronitis is made and he enquires what treatment will help his symptoms.
What is the most suitable initial treatment?
