      Mechanism Description
  • Additive hypotensive effects by the combination of Nefazodone and Guanethidine 

Recommended Action
      Management Caution and close monitoring for altered efficacy and safety are recommended if patients receive nefazodone with agents that can produce significant hypotension such as antihypertensive agents or vasodilators. Patients should be made aware of the possible side effects (e.g., dizziness, lightheadedness, orthostasis) and be cautioned about driving, operating machinery, or performing other hazardous tasks.
