Nesiritide Side Effects: Safety Signals and Warnings
Nesiritide safety concerns are compound-specific. The main listed side effects are Hypotension (dose-limiting), Headache, and Nausea. The main warning signals are Hypotension is the most significant adverse effect - avoid in patients with SBP <100 mmHg, Should not be used as primary therapy for cardiogenic shock, and Monitor renal function during infusion.
Direct Answer
Nesiritide (Natrecor) is FDA-approved for acute decompensated heart failure with initial enthusiasm tempered by subsequent analysis showing limited mortality benefit and possible renal harm at higher doses. Current guidelines reserve it for symptom relief when other therapies are inadequate. It is a validated BNP analog with a well-characterized pharmacology, but its role in HF management has narrowed with evolving evidence.

Warnings
- Hypotension is the most significant adverse effect - avoid in patients with SBP <100 mmHg
- Should not be used as primary therapy for cardiogenic shock
- Monitor renal function during infusion
- Limited long-term outcome data - use for symptom relief, not mortality reduction
Known or Plausible Interactions
- ACE inhibitors (additive hypotension)
- ARBs (additive hypotension)
- Diuretics (enhanced natriuretic effect, risk of volume depletion)
- IV vasodilators (additive hemodynamic effects)
Regulatory Context
FDA-approved (2001) for treatment of acutely decompensated heart failure. Available by prescription for hospital/clinic use only. Marketed as Natrecor by Janssen.
