isosorbide ⇔ nefazodone

Applies to: isosorbide and nefazodone

MONITOR: Nefazodone may potentiate the hypotensive effect of many drugs including vasodilators and antihypertensive agents. Orthostatic hypotension may occur. In clinical studies, nefazodone was associated with potentially significant blood pressure decreases (SBP 90 mmHg or less and at least 20 mmHg decrease from baseline) in 5.1% of patients, postural hypotension in 2.8%, and syncope in 0.2% (versus 0.3% for placebo).

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. They should also be advised to avoid rising abruptly from a sitting or recumbent position and to contact their physician if they experience symptoms of hypotension such as dizziness, lightheadedness, or fainting.
