Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE Phentolamine Mesylate for Injection, USP is indicated for the prevention or control of hypertensive episodes that may occur in a patient with pheochromocytoma as a result of stress or manipulation during preoperative preparation and surgical excision. Phentolamine Mesylate for Injection, USP is indicated for the prevention or treatment of dermal necrosis and sloughing following intravenous administration or extravasation of norepinephrine. Phentolamine Mesylate for Injection, USP is also indicated for the diagnosis of pheochromocytoma by the Phentolamine Mesylate for Injection, USP blocking test.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION The reconstituted solution should be used upon preparation and should not be stored. Note: Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. 1.
Prevention or control of hypertensive episodes in the patient with pheochromocytoma. For preoperative reduction of elevated blood pressure, 5 mg of Phentolamine Mesylate for Injection, USP (1mg for children) is injected intravenously or intramuscularly 1 or 2 hours before surgery, and repeated if necessary. During surgery, Phentolamine Mesylate for Injection, USP (5 mg for adults, 1 mg for children) is administered intravenously as indicated, to help prevent or control paroxysms of hypertension, tachycardia, respiratory depression, convulsions, or other effects of epinephrine intoxication.
(Postoperatively, norepinephrine may be given to control the hypotension that commonly follows complete removal of a pheochromocytoma.) 2. Prevention or treatment of dermal necrosis and sloughing following intravenous administration or extravasation of norepinephrine. For Prevention: 10 mg of Phentolamine Mesylate for Injection, USP is added to each liter of solution containing norepinephrine.
The pressor effect of norepinephrine is not affected. For Treatment: 5-10 mg of Phentolamine Mesylate for Injection, USP in 10 mL of saline is injected into the area of extravasation within 12 hours. 3.
Diagnosis of pheochromocytoma — Phentolamine Mesylate for Injection, USP blocking test. The test is most reliable in detecting pheochromocytoma in patients with sustained hypertension and least reliable in those with paroxysmal hypertension. False-positive tests may occur in patients with hypertension without pheochromocytoma. a.
Intravenous Preparation The CONTRAINDICATIONS , WARNINGS , and PRECAUTIONS sections should be reviewed. Sedatives, analgesics, and all other medications except those that might be deemed essential (such as digitalis and insulin) are withheld for at least 24 hours, and preferably 48 -72 hours, prior to the test. Antihypertensive drugs are withheld until blood pressure returns to the untreated, hypertensive level.
This test is not performed on a patient who is normotensive. Procedure The patient is kept at rest in the supine position throughout the test, preferably in a quiet, darkened room. Injection of Phentolamine Mesylate for Injection, USP is delayed until blood pressure is stabilized, as evidenced by blood pressure readings taken every 10 minutes for at least 30 minutes.
Five milligrams of Phentolamine Mesylate for Injection, USP is dissolved in 1mL of Sterile Water for Injection. The dose for adults is 5 mg; for children, 1 mg. The syringe needle is inserted into the vein, and injection is delayed until pressor response to venipuncture has subsided.
Phentolamine Mesylate for Injection, USP is injected rapidly. Blood pressure is recorded immediately after injection, at 30-second intervals for the first 3 minutes, and at 60-second intervals for the next 7 minutes. Interpretation A positive response, suggestive of pheochromocytoma, is indicated when the blood pressure is reduced more than 35 mmHg systolic and 25 mmHg diastolic.
A typical positive response is a reduction in pressure of 60 mmHg systolic and 25 mmHg diastolic. Usually, maximal effect is evident within 2 minutes after injection. A return to preinjection pressure commonly occurs within 15-30 minutes but may occur more rapidly.
If blood pressure decreases to a dangerous level, the patient should be treated as outlined under OVERDOSAGE . A positive response should always be confirmed by other diagnostic procedures, preferably by measurement of urinary catecholamines or their metabolites. A negative response is indicated when the blood pressure is elevated, unchanged, or reduced less than 35 mmHg, systolic and 25 mmHg diastolic after injection of Phentolamine Mesylate for Injection, USP.

⛔ Contraindications ▾
CONTRAINDICATIONS Myocardial infarction, history of myocardial infarction, coronary insufficiency, angina or other evidence suggestive of coronary artery disease; hypersensitivity to phentolamine or related compounds.
⚠️ Warnings ▾
WARNINGS Myocardial infarction, cerebrovascular spasm, and cerebrovascular occlusion have been reported to occur following the administration of Phentolamine Mesylate for Injection, USP, usually in association with marked hypotensive episodes. For screening tests in patients with hypertension, the generally available urinary assay of catecholamines or other biochemical assays have largely replaced the Phentolamine Mesylate for Injection, USP and other pharmacological tests for reasons of accuracy and safety. None of the chemical or pharmacological tests is infallible in the diagnosis of pheochromocytoma.
The Phentolamine Mesylate for Injection, USP blocking test is not the procedure of choice and should be reserved for cases in which additional confirmatory evidence is necessary and the relative risks involved in conducting the test have been considered.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Acute and prolonged hypotensive episodes, tachycardia, and cardiac arrhythmias have been reported. In addition, weakness, dizziness, flushing, orthostatic hypotension, nasal stuffiness, nausea, vomiting, and diarrhea may occur. To report SUSPECTED ADVERSE REACTIONS, contact Precision Dose Inc. at 1-844-668-3942 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

🤰 Pregnancy ▾
Pregnancy Category C Administration of Phentolamine Mesylate for Injection, USP to pregnant rats and mice at oral doses 24-30 times the usual daily human dose (based on a 60-kg human) resulted in slightly decreased growth and slight skeletal immaturity of the fetuses. Immaturity was manifested by increased incidence of incomplete or unossified calcanei and phalangeal nuclei of the hind limb and of incompletely ossified sternebrae. At oral doses 60 times the usual daily human dose (based on a 60-kg human), a slightly lower rate of implantation was found in the rat.
Phentolamine Mesylate for Injection, USP did not affect embryonic or fetal development in the rabbit at oral doses 20 times the usual daily human dose (based on a 60-kg human). No teratogenic or embryo toxic effects were observed in the rat, mouse, or rabbit studies. There are no adequate and well-controlled studies in pregnant women.
Phentolamine Mesylate for Injection, USP should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
🆘 Overdosage ▾
OVERDOSAGE Acute Toxicity No deaths due to acute poisoning with Phentolamine Mesylate for Injection, USP have been reported. Oral LD 50 's (mg/kg): mice, 1000; rats, 1250. Signs and Symptoms Overdosage with Phentolamine Mesylate for Injection, USP is characterized chiefly by cardiovascular disturbances, such as arrhythmias, tachycardia, hypotension, and possibly shock.
In addition, the following might occur: excitation, headache, sweating, pupillary contraction, visual disturbances; nausea, vomiting, diarrhea; hypoglycemia. Treatment There is no specific antidote. A decrease in blood pressure to dangerous levels or other evidence of shock like conditions should be treated vigorously and promptly.
The patient's legs should be kept raised and a plasma expander should be administered. If necessary, intravenous infusion of norepinephrine, titrated to maintain blood pressure at the normotensive level, and all available supportive measures should be included. Epinephrine should not be used, since it may cause a paradoxical reduction in blood pressure.
