Note: This document contains side effect information about nitroprusside. Some dosage forms listed on this page may not apply to the brand name Nipride RTU.
Applies to nitroprusside: intravenous solution.
Warning
Intravenous route (Solution)
Sodium nitroprusside may cause precipitous decreases in blood pressure and may lead to irreversible ischemic injuries or death. Continuous blood pressure monitoring is required. Sodium nitroprusside metabolism produces dose-related cyanide and may be lethal. Limit infusions at the maximum rate (10 mcg/kg/min) to the shortest duration possible as patient's ability to buffer cyanide will be exceeded in less than 1 hour at this rate.
Intravenous route (Solution)
Sodium nitroprusside is not suitable for direct injection; the reconstituted solution must be further diluted in sterile 5% dextrose injection before infusion. Sodium nitroprusside can cause precipitous decreases in blood pressure; monitor blood pressure continuously while patient is on therapy. Nitroprusside can cause cyanide toxicity which can be lethal. Infusion at the maximum dose rate (10 mcg/kg/min) should never last more than 10 minutes. Monitor acid-base balance and venous oxygen concentration while on therapy; these tests may indicate cyanide toxicity.
