Medication is a mainstay of treatment of Parkinson’s disease (PD), and can vary for each person with PD. Each medication has its own properties, and healthcare professionals have reasons to choose certain ones at various times as conditions warrant. At those times, people with PD and their care partners need to ask questions about the reasons for starting specific medications, what they can expect, and whether they will interact well with other medications. This advice applies to all medications, not just ones for PD. All healthcare providers need to be aware that someone has PD and what medications they are taking because not only can they interact with other medications, but they may also affect what procedures can be performed and when. Emily Peron, PharmD, of Virginia Commonwealth University School of Pharmacy in Richmond discusses these issues and more, with advice about medications, their effects and adverse effects, and medication changes.
