polypharmacy
The concurrent use of multiple medications, often referring to potentially inappropriate or excessive medication regimens.
Full Definition
Polypharmacy in psychiatry refers to the simultaneous use of multiple psychotropic medications, which may be appropriate for complex conditions but can also indicate suboptimal prescribing practices. While legitimate polypharmacy involves evidence-based combinations for treatment-resistant conditions, problematic polypharmacy occurs when medications are added without discontinuing ineffective treatments, leading to increased side effects, drug interactions, and reduced adherence. Psychiatric polypharmacy requires careful monitoring of therapeutic benefits versus risks, regular medication reviews, and documentation of the rationale for each medication in the regimen.
Usage
Usage note: Can be appropriate for complex conditions but requires justification and monitoring.
