Disease interactions
12 potential interactions Applies to: 11 conditions, including High Blood Pressure, Underactive Thyroid, Benign Prostatic Hyperplasia, Hyperthyroidism, and Diabetes Mellitus.
Benign Prostatic Hyperplasia
Moderate:
Primatene
The ePHEDrine in Primatene has a moderate potential interaction with Benign Prostatic Hyperplasia.
Sympathomimetic agents may cause or worsen urinary difficulty in patients with prostate enlargement due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate.
Cardiovascular Conditions and Disorders
Major:
Primatene
The ePHEDrine in Primatene has a major potential interaction with Cardiovascular Conditions and Disorders.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Cerebrovascular Insufficiency
Major:
Primatene
The ePHEDrine in Primatene has a major potential interaction with Cerebrovascular Insufficiency.

Diabetes Mellitus
Moderate:
Primatene
The ePHEDrine in Primatene has a moderate potential interaction with Diabetes Mellitus.
Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.
Moderate:
Primatene
The ePHEDrine in Primatene has a moderate potential interaction with Diabetes Mellitus.
Ephedrine may produce slight increases in blood glucose concentrations. Therapy with ephedrine should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. It is important that the recommended dosages of ephedrine are not exceeded.
High Blood Pressure
Moderate:
iobenguane I 131
The iobenguane I-131 in iobenguane I 131 has a moderate potential interaction with High Blood Pressure.
Eleven percent of patients who received a therapeutic dose of iobenguane I-131 experienced a worsening of preexisting hypertension defined as an increase in systolic blood pressure to =160 mmHg with an increase of 20 mmHg or an increase in diastolic blood pressure to = 100 mmHg with an increase of 10 mmHg. All changes in blood pressure occurred within the first 24 hours post infusion. Blood pressure should be frequently monitored during the first 24 hours after each therapeutic dose of iobenguane I-131.
Hyperthyroidism
Major:
Primatene
The ePHEDrine in Primatene has a major potential interaction with Hyperthyroidism.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Pheochromocytoma
Major:
Primatene
The ePHEDrine in Primatene has a major potential interaction with Pheochromocytoma.
Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors.

These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.
Prostate Tumor, Benign
Moderate:
Primatene
The ePHEDrine in Primatene has a moderate potential interaction with Prostate Tumor, Benign.
Sympathomimetic agents may cause or worsen urinary difficulty in patients with prostate enlargement due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate.
Renal Dysfunction
Moderate:
iobenguane I 131
The iobenguane I-131 in iobenguane I 131 has a moderate potential interaction with Renal Dysfunction.
Renal failure or acute kidney injury and a demonstrated clinically significant decrease in glomerular filtration rate (GFR) has been reported in some patients receiving iobenguane I-131. Monitor renal function during and after treatment with iobenguane I-131. Patients with baseline renal impairment may be at greater risk of toxicity, and their radiation dose may be increased due to the delayed elimination of the drug. Adjust the therapeutic dose based on radiation exposure estimates from the dosimetry assessment. Perform more frequent assessments of renal function in patients with mild or moderate impairment. Iobenguane I-131 has not been studied in patients with severe renal impairment (creatinine clearance <30 mL/min), or end-stage renal disease.
Underactive Thyroid
Moderate:
iobenguane I 131
The iobenguane I-131 in iobenguane I 131 has a moderate potential interaction with Underactive Thyroid.
Hypothyroidism was reported in patients who received a therapeutic dose of iobenguane I-131. Caution and close monitoring is advised in patients with history of hypothyroidism. Initiate thyroid- blocking medications starting at least 1 day before and continuing for 10 days after each iobenguane I-131 dose to reduce the risk of hypothyroidism or thyroid neoplasia. Evaluate for clinical evidence of hypothyroidism and measure thyroid-stimulating hormone (TSH) levels prior to initiating treatment with iobenguane I-131 and annually thereafter.
Urinary Tract Obstruction
Moderate:
Primatene
The ePHEDrine in Primatene has a moderate potential interaction with Urinary Tract Obstruction.
Sympathomimetic agents such as ephedrine have the potential for producing clinically significant systemic effects, particularly during prolonged or indiscriminate use. In patients with prostate enlargement, urinary difficulty may develop or worsen due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with ephedrine should be administered cautiously in patients with difficulty for urination due to hypertrophy or neoplasm of the prostate. It is important that the recommended dosages are not exceeded.
