Norepinephrine Bitartrate Injection is indicated to raise blood pressure in adult patients with severe, acute hypotension. None. Risk Summary Limited published data consisting of a small number of case reports and multiple small trials involving the use of norepinephrine in pregnant women at the time of delivery have not identified an increased risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There are risks to the mother and fetus from hypotension associated with septic shock, myocardial infarction and stroke which are medical emergencies in pregnancy and can be fatal if left untreated. (see Clinical Considerations) . In animal reproduction studies, using high doses of intravenous norepinephrine resulted in lowered maternal placental blood flow. Clinical relevance to changes in the human fetus is unknown since the average maintenance dose is ten times lower (see Data). Increased fetal reabsorptions were observed in pregnant hamsters after receiving daily injections at approxim

INDICATIONS AND USAGE
Norepinephrine Bitartrate Injection is a catecholamine indicated for
restoration of blood pressure in adult
patients with acute hypotensive states. (1)
DOSAGE AND ADMINISTRATION
Initial dose of 0.25 mL to 0.375 mL (from 8 mcg to 12 mcg of base) per
minute, adjust the rate of flow
to establish and maintain a low to normal blood pressure (usually 80
mm Hg to 100 mm Hg systolic)
sufficient to maintain the circulation of vital organs. (2.2)
The average maintenance dose ranges from 0.0625 mL to 0.125 mL per
minute (from 2 mcg to 4 mcg
of base). (2.2)
DOSAGE FORMS AND STRENGTHS
Injection: 4 mg/4 mL (1 mg/mL) norepinephrine base in single-dose
glass vial. (3)
CONTRAINDICATIONS
None (4)
WARNINGS AND PRECAUTIONS
Tissue Ischemia: Avoid extravasation of norepinephrine bitartrate into
the tissues, as local necrosis
might ensue due to the vasoconstrictive action of the drug. Infuse
norepinephrine bitartrate into a large
vein. To prevent sloughing and necrosis in areas in which
extravasation has taken place, the area
should be infiltrated as soon as possible with 10 mL to 15 mL of
saline solution containing from 5 mg
to 10 mg of an adrenergic blocking agent. (5.1)
Hypotension After Abrupt Discontinuation: Sudden cessation of
theinfusion rate may result in marked
hypotension. Reduce the norepinephrine bitartrate infusion rate
gradually. (5.2)
Cardiac Arrhythmias: Norepinephrine Bitartrate may cause arrhythmias.
Monitor cardiac function in
patients with underlying heart disease. (5.3)
Allergic Reactions with Sulfite: Norepinephrine Bitartrate contains
sodium metabisulfite. Sulfite may
cause aller
