4.6.2 Drugs for the treatment of labyrinthine vertigo
|1st choices||Cinnarizine tablets 15mg||Dose:|
15-30mg three times daily
|Prochlorperazine tablets 5mg; syrup 5mg/ml||Dose:|
5mg three times daily, gradually increased if required to 30mg daily in divided doses, and reduced after several weeks to 5-10mg daily
- These products are only effective for labyrinthine vertigo.
- Prochlorperazine buccal tablets may be a suitable alternative for patients who are vomiting.
- Prochlorperazine should not be prescribed for “dizziness” in older patients due to the risk of drug-induced parkinsonism, postural hypotension and mental confusion.
- Prolonged use of cinnarizine in the treatment of labyrinthine vertigo can cause tremor.
- Betahistine use may delay labyrinthine rehabilitation.
- Patients prescribed drugs for the treatment of nausea and vertigo should be reviewed regularly and medicines which are not of benefit should be stopped.
