Drug interactions
Mirogabalin + Pregabalin
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Therapeutic duplication of gabapentinoids with additive CNS depression (sedation, dizziness, ataxia), cognitive impairment, and potential respiratory depression; increased risk of peripheral edema. Limited clinical rationale for concurrent use.
Mechanism of action
Additive pharmacodynamic effect as alpha-2-delta calcium channel ligands; minimal pharmacokinetic interaction expected since both are renally eliminated with negligible CYP involvement.
Clinical management
Avoid concurrent use when possible; select a single gabapentinoid. If cross-tapering, use the lowest effective doses with brief overlap and close monitoring for CNS depression and respiratory status. Adjust doses for renal function and counsel on fall risk and impaired alertness.
