polypharmacy
The concurrent use of multiple medications, particularly when the number or combination may increase the risk of adverse effects or drug interactions.
Full Definition
Polypharmacy in psychiatric practice refers to the simultaneous use of multiple psychotropic medications, often defined as five or more concurrent medications or the use of multiple agents within the same therapeutic class. While sometimes clinically justified for complex conditions or treatment-resistant cases, polypharmacy increases risks of drug interactions, adverse effects, medication errors, and reduced adherence. In psychiatric settings, polypharmacy may occur through layering of medications over time, combination therapy for comorbid conditions, or augmentation strategies. Careful monitoring and periodic medication reviews are essential to minimize unnecessary polypharmacy.
Usage
Usage note: Generally carries negative connotations; use 'combination therapy' for intentional, clinically justified multiple medications.
