  • Tizanidine is a muscle relaxant (Schedule 4 prescription): an alpha-2 agonist with antispasmodic action; requires monitoring of operational health for low blood pressure and liver function changes.
  • Orphenadrine (Schedule 4 prescription): an anticholinergic muscle relaxant; adverse effects can include dry mouth, blurred vision and dizziness.
  • Diazepam (Schedule 4 prescription): a benzodiazepine with muscle relaxant effects; effective short term but associated with dependence and sedation with longer use.
