Drug interaction information between Pregabalin and Lorazepam.
Pregabalin and Lorazepam have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Pregabalin and Lorazepam. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.

Understanding the Pregabalin and Lorazepam Interaction
FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Pregabalin belongs to the Anticonvulsant / Nerve Pain Agent class and Lorazepam belongs to the Benzodiazepine class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Both drugs can slow down brain activity, which can lead to increased sleepiness or dizziness when they are used together. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.
Context around a specific patient determines real-world impact. Pregabalin has 14 total documented interactions on file in this dataset, and Lorazepam has 11. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Be careful when taking these together and monitor yourself for increased drowsiness or dizziness. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.
An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Pregabalin or Lorazepam based on a web page, speak with your prescriber or pharmacist before making any change.
