Black Box Warning

See full prescribing information for complete Boxed Warning.
* NITROPRESS® (Sodium Nitroprusside Injection) is not suitable for direct injection. The solution must be further diluted in sterile 5% dextrose injection before infusion.
  • NITROPRESS can cause precipitous decreases in blood pressure (see DOSAGE AND ADMINISTRATION). In patients not properly monitored, these decreases can lead to irreversible ischemic injuries or death. Sodium nitroprusside should be used only when available equipment and personnel allow blood pressure to be continuously monitored.
  • Except when used briefly or at low (< 2 mcg/kg/min) infusion rates, sodium nitroprusside gives rise to important quantities of cyanide ion, which can reach toxic, potentially lethal levels (see WARNINGS). The usual dose rate is 0.5-10 mcg/kg/min, but infusion at the maximum dose rate should never last more than 10 minutes. If blood pressure has not been adequately controlled after 10 minutes of infusion at the maximum rate, administration of sodium nitroprusside should be terminated immediately.
  • Although acid-base balance and venous oxygen concentration should be monitored and may indicate cyanide toxicity, these laboratory tests provide imperfect guidance.

Overview

Nitroprusside is a vasodilator that is FDA approved for the {{{indicationType}}} of hypertensive crises and acute congestive heart failure. It is also indicated for producing controlled hypotension in order to reduce bleeding during surgery.. There is a Black Box Warning for this drug as shown here. Common adverse reactions include excessive hypotension and cyanide toxicity.

Administration and Monitoring

Administration

  • Dilution to proper strength for infusion
  • Depending on the desired concentration, the solution containing 50 mg of NITROPRESS must be further diluted in 250-1000 mL of sterile 5% dextrose injection. The diluted solution should be protected from light, using the supplied opaque sleeve, aluminum foil, or other opaque material. It is not necessary to cover the infusion drip chamber or the tubing.
  • Verification of the chemical integrity of the product
  • Sodium nitroprusside solution can be inactivated by reactions with trace contaminants. The products of these reactions are often blue, green, or red, much brighter than the faint brownish color of unreacted NITROPRESS. Discolored solutions, or solutions in which particulate matter is visible, should not be used. If properly protected from light, the freshly diluted solution is stable for 24 hours.
  • No other drugs should be administered in the same solution with sodium nitroprusside.

Monitoring

Blood Pressure and Urine Output
  • Because sodium nitroprusside can induce essentially unlimited blood pressure reduction, the blood pressure of a patient receiving this drug must be continuously monitored, using either a continually reinflated sphygmomanometer or (preferably) an intra-arterial pressure sensor. Special caution should be used in elderly patients, since they may be more sensitive to the hypotensive effects of the drug.
  • When sodium nitroprusside is used in the treatment of acute congestive heart failure, titration of the infusion rate must be guided by the results of invasive hemodynamic monitoring with simultaneous monitoring of urine output.
