Like all medications, Norages can produce side effects, although not everyone will experience them
Vein leakage can cause destruction of the surrounding tissue
It can cause a decrease in heart rate
Prolonged use can decrease heart output
Prolonged administration of this type of substance can cause blood loss, which, if not corrected, can cause a relapse in blood pressure when treatment is suspended
It can cause severe narrowing of the body's veins and viscera (e.g., decreased blood flow to the kidney) with decreased blood flow and tissue perfusion, resulting in tissue hypoxia, increased blood acidity, and damage due to poor blood flow
Although rare, the following symptoms may occur during application and require medical attention:
Skin disorders: Pale skin along the infusion vein, scarring, blue discoloration, flushing or redness of the skin, skin rash, urticaria, or pruritus
Cardiovascular system disorders: Irregular heartbeats, decreased heart rate
Respiratory system disorders: Wheezing or difficulty breathing
General disorders: Severe dizziness or feeling of fainting
Less frequently, the following symptoms may occur and require medical attention only if they last or are bothersome:
Skin disorders: Pale skin
Cardiovascular system disorders: Palpitations
Nervous system disorders: Anxiety or restlessness, sleep problems, tremors, headache
General disorders: Dizziness, swelling in the neck
In sensitive individuals, for example, people with nervous system diseases or hyperthyroidism, it produces:
Nervous system disorders: Fear, anxiety, pulsating headache, and difficulty breathing
Cardiovascular system disorders: Pale skin, tachycardia, palpitations, slight elevation of blood pressure
If you experience side effects, consult your doctor or pharmacist, even if they are side effects that do not appear in this prospectus

This information is intended solely for doctors or healthcare professionals:
Dosage and administration
Norepinephrine should be administered intravenously:
Usual adult dosage
The initial dose is administered at a rate of 8 to 12 micrograms (0.008 to 0.012 mg) (base) per minute, adjusting the rate of administration to establish and maintain the desired blood pressure.
To maintain, the rate is adjusted from 2 to 4 micrograms (0.002 to 0.004 mg) (base) per minute, titrating the dosage according to the patient's response.
In the case of septic shock, the doses should be adjusted around 0.5 micrograms/kg/min (up to a maximum of 1.0 micrograms/kg/min) to achieve the desired mean blood pressure. It is recommended to administer it along with doses of 2 – 2.5 micrograms/kg/min of dopamine, which counteract vasoconstriction, ensuring good renal and splenic circulation.
- To prepare the solution for intravenous infusion of norepinephrine, add 4 mg of L-norepinephrine (base) to 1 liter of 5% glucose solution. The resulting solution will contain 4 micrograms (0.004 mg) of L-norepinephrine (base) per ml. It should be noted that 1 mg of L-norepinephrine bitartrate is equivalent to 0.5 mg of L-norepinephrine base.
Duration of treatment
The infusion should be continued until the desired blood pressure and tissue perfusion are maintained without treatment. The norepinephrine infusion should be gradually reduced, avoiding abrupt interruption. In some cases described of vascular collapse due to acute myocardial infarction, treatment was required for up to six days.
Usual pediatric dosage
Intravenous infusion, 0.1 micrograms (base) per kg per minute, adjusting the rate of administration gradually to achieve the desired blood pressure, up to 1 microgram (base) per kg per minute.
- When added to local anesthetics, these solutions contain a concentration of norepinephrine around 1: 200,000 (5 micrograms/ml).
Administration should be avoided:
- Norepinephrine should not be used as the sole therapy in hypotensive patients due to hypovolemia, except as an emergency measure to maintain coronary and cerebral perfusion until volume replacement therapy is completed.
- Administration should be avoided in the veins of the lower limbs of elderly patients and patients with occlusive diseases due to possible vasoconstriction.
- Accidental cases may occur where, if proper precautions are not taken, extravasation or even gangrene may occur. To avoid necrosis and scarring of the tissue in the area where extravasation has occurred, the area should be infiltrated immediately with 10 to 15 ml of sodium chloride solution containing 5 to 10 mg of fentolamine. A hypodermic needle and syringe should be used, and the solution should be infiltrated abundantly throughout the area. If the area is infiltrated within 12 hours, the sympathetic block with fentolamine produces immediate and perceptible local hyperemia.
- The lost blood volume should be replenished as completely as possible before administering any vasopressor.
Special precautions for use
- Before administration, norepinephrine injectable should be diluted with 5% glucose solution in distilled water or 5% glucose solution in sodium chloride solution. Sodium chloride solution alone should not be used.
- To prepare the solution for intravenous infusion of norepinephrine, add 4 mg of L-norepinephrine (base) to 1 liter of 5% glucose solution. The resulting solution will contain 4 micrograms (0.004 mg) of L-norepinephrine (base) per ml. It should be noted that 1 mg of L-norepinephrine bitartrate is equivalent to 0.5 mg of L-norepinephrine base.
- Use a controlled infusion system to achieve a precise estimate of the flow rate in drops per minute. The infusion should be performed in veins of upper limbs.
- The technique of ligature of the catheter should be avoided, if possible, because obstruction of blood flow around the tube may cause stasis and increased local concentration of norepinephrine.
- Do not use the injectable if it has a brown color or contains precipitate.
Overdose
Symptoms
Overdose causes severe hypertension with intense headache, photophobia, acute retrosternal pain, pharyngeal pain, intense pallor, and sweating, and vomiting.
Emergency treatment, antidotes
The recommended treatment for norepinephrine overdose includes:
for hypertension: if necessary, a α-adrenergic blocker can be administered intravenously with 5 to 10 mg of fentolamine.
