Medication

Pramipexole

Antiparkinsonian (dopamine agonist)

Brand names: Mirapex

Oral health effects

  • Xerostomia (dry mouth)

    Reduced salivary flow with elevated caries and discomfort risk.

    Clinical management: Hydration, salivary substitutes, high-fluoride caries prevention.

  • Dizziness on standing (orthostatic hypotension)

    Symptomatic orthostatic hypotension is a label warning for dopamine agonists, especially during dose escalation (3% vs 1% on placebo in Parkinson's trials).

    Clinical management: Raise the chair slowly at the end of the appointment and have the patient sit upright for a minute or two before standing; steady them as they get up. Ask about dizziness on standing, especially after dose changes or in older patients.

  • Involuntary movements (dyskinesia)

    Dopamine agonists can cause or worsen dyskinesia, including orofacial movements, especially with levodopa (label: 17–18% when added to levodopa (vs 8% with extended-release)).

    Clinical management: Expect involuntary jaw, tongue or limb movements that can interrupt instrumentation; use short appointments, bite blocks and good head support, and schedule care when medication is working well (patient-reported 'on' time).
