What is drug-induced parkinsonism (DIP) and how does it differ from Parkinson's disease?
DIP is the second most common cause of parkinsonism symptoms in older adults. Unlike Parkinson's disease, DIP is caused by certain medications that affect dopamine levels in the brain. The good news is that DIP symptoms are usually temporary and typically fade within weeks to a year after stopping the triggering medication. Common medications that may cause DIP include:
• Antipsychotics (like haloperidol and chlorpromazine)
• Anti-nausea medications (like metoclopramide)
• Some antidepressants (like fluoxetine and sertraline)
• Calcium channel blockers
• Dopamine depleters
Risk factors for developing DIP include:
• Older age
• Being female (due to estrogen's effects on dopamine receptors) The symptoms of DIP can look similar to Parkinson's disease, including:
• Tremors (shaking)
• Muscle rigidity
• Slow movements
• Walking difficulties
• Reduced automatic responses like blinking
If you're concerned about medications causing these symptoms, speak with your healthcare provider before making any changes to your medication routine.
