Drug Interactions
Pregabalin is excreted essentially unchanged by the kidneys with negligible metabolism, so it has very few pharmacokinetic interactions. Most clinically important interactions are pharmacodynamic, particularly involving CNS depression.
- Opioids (e.g., oxycodone, morphine, fentanyl, tramadol): Concurrent use significantly increases the risk of respiratory depression, sedation, and overdose death. An FDA warning highlights this combination. Use the lowest doses, monitor closely, and provide naloxone in higher-risk patients.
- Benzodiazepines and other CNS depressants (e.g., alcohol, sedating antihistamines, sleep medications): Additive sedation and respiratory depression. Counsel patients to avoid alcohol and report excessive drowsiness.
- ACE inhibitors: Reports of increased risk of angioedema with concurrent use. Be alert for facial, lip, or tongue swelling, particularly in the early weeks of combined therapy.
- Thiazolidinediones (e.g., pioglitazone): Both drugs cause weight gain and peripheral edema; combination therapy may worsen these effects, particularly in patients with heart failure risk.
- Gabapentin: Mechanistically similar; concurrent use offers no added benefit and increases CNS depression. Avoid combination.
