What are the potential side effects of dopaminergic treatments for Restless Legs Syndrome that I should discuss with my patients?

Potential side effects of dopaminergic treatments for Restless Legs Syndrome (RLS) that should be discussed with patients include:

• Augmentation: This is a worsening of RLS symptoms that may require increasing the dose of dopamine agonists. It is a common and significant risk associated with dopaminergic therapy in RLS.
• Impulse Control Disorders (ICDs): Patients may develop impulse control disorders such as compulsive gambling, hypersexuality, binge eating, and obsessive shopping. These can be concealed by the patient and require regular monitoring.
• Rebound symptoms: Abrupt discontinuation of dopamine agonists can cause dramatic rebound worsening of RLS symptoms, so gradual tapering is recommended.
• Other adverse effects: Although not detailed specifically for RLS in the provided context, dopaminergic treatments in related conditions (e.g., Parkinson's disease) are associated with side effects such as hallucinations and orthostatic hypotension, which may be relevant considerations.

Patients should be informed that dopaminergic treatments are generally considered for short-term or specific circumstances due to these risks, and regular monitoring for augmentation and impulse control disorders is essential during treatment.

Clinicians should discuss these potential side effects with patients before starting dopaminergic therapy and during follow-up reviews to ensure early detection and management.
