Allergies

Moderate:

gadoterate meglumine

Gadoterate meglumine has a moderate potential interaction with Allergies.

Patients with history of bronchial asthma might have an increased risk for a hypersensitivity reaction to gadolinium-based contrast agents. Patients should always be assessed for any history of a reaction to contrast media, asthma or other allergic disorders before the administration of these agents.

Asthma

Moderate:

gadoterate meglumine

Gadoterate meglumine has a moderate potential interaction with Asthma.

Patients with history of bronchial asthma might have an increased risk for a hypersensitivity reaction to gadolinium-based contrast agents. Patients should always be assessed for any history of a reaction to contrast media, asthma or other allergic disorders before the administration of these agents.

Benign Prostatic Hyperplasia

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE 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:

Guaifen PE

The phenylephrine in Guaifen PE 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:

Guaifen PE

The phenylephrine in Guaifen PE has a major potential interaction with Cerebrovascular Insufficiency.

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.

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.

Diabetes Mellitus

Major:

gadoterate meglumine

Gadoterate meglumine has a major potential interaction with Diabetes Mellitus.

Gadolinium-based contrast agents (GBCAs) increase the risk for nephrogenic systemic fibrosis (NSF) among patients with impaired elimination of the drugs. Gadobenate ion is eliminated predominately via the kidneys. The risk for NSF appears highest among patients with chronic, severe kidney disease (GFR <30 mL/min/1.73m2), or acute kidney injury. It is recommended to avoid the use of GBCAs in these patients unless the diagnostic information is essential and not available with non-contrasted MRI or other processes. NSF may result in fatal or debilitating systemic fibrosis affecting the skin, muscle and internal organs. Consider screening patients for acute kidney injury and other conditions that may reduce renal function and for patients at risk for chronically reduced renal function (e.g., age > 60 years, hypertension or diabetes), estimate the glomerular filtration rate (GFR) through laboratory testing. For patients receiving hemodialysis, physicians may consider the prompt initiation of hemodialysis following the administration of a GBCA to enhance the contrast agent's elimination. The usefulness of hemodialysis in the prevention of NSF is unknown.

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE 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.

Glaucoma/Intraocular Hypertension

Moderate:

Guaifen PE

The phenylephrine in Guaifen PE has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors. In patients with anatomically narrow angles or narrow-angle glaucoma, pupillary dilation can provoke an acute attack. In patients with other forms of glaucoma, mydriasis may occasionally increase intraocular pressure. Therapy with sympathomimetic agents should be administered cautiously in patients with or predisposed to glaucoma, particularly narrow-angle glaucoma.
