Interactions between your drugs

Major

pseudoephedrine iobenguane I-131

Applies to: Zymine-D (pseudoephedrine / triprolidine) and iobenguane I 131

GENERALLY AVOID: Coadministration with drugs that reduce catecholamine uptake or deplete catecholamine stores may interfere with iobenguane I-131 uptake into neuroendocrine tumors such as pheochromocytoma and paraganglioma that express high levels of norepinephrine transporter on their cell surfaces. Since iobenguane is similar in structure to norepinephrine and is subject to the same uptake and accumulation pathways as norepinephrine, drugs that alter norepinephrine disposition in adrenergic nerve terminals and presynaptic storage vesicles will likewise affect iobenguane. Dosimetry calculations and efficacy of iobenguane I-131 may be altered. These drugs include central nervous system stimulants (e.g., amphetamines, cocaine, methylphenidate); norepinephrine and dopamine reuptake inhibitors (e.g., phentermine); norepinephrine and serotonin reuptake inhibitors (e.g., tramadol); central monoamine depleting drugs (e.g., reserpine); nonselective beta-adrenergic blockers (e.g., labetalol); alpha agonists or alpha/beta agonists (e.g., pseudoephedrine, phenylephrine, ephedrine, phenylpropanolamine, naphazoline); monoamine oxidase inhibitors; tricyclic antidepressants; norepinephrine reuptake inhibitors (e.g., bupropion, duloxetine, mirtazapine, venlafaxine); and botanicals that may inhibit reuptake of norepinephrine, serotonin, or dopamine (e.g., ephedra, ma huang, St John's wort, yohimbine). These drugs were not permitted in clinical trials that assessed the safety and efficacy of iobenguane I-131.

MANAGEMENT: Drugs that reduce catecholamine uptake or deplete catecholamine stores should be discontinued for at least five biological half-lives before administration of either the dosimetry dose or a therapeutic dose of iobenguane I-131. Do not administer these drugs until at least 7 days after each iobenguane I-131 dose. Patients should be monitored for the occurrence of clinically significant withdrawal symptoms, especially patients with elevated levels of circulating catecholamines and their metabolites.

Drug and food interactions

Moderate

triprolidine food

Applies to: Zymine-D (pseudoephedrine / triprolidine)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

pseudoephedrine food

Applies to: Zymine-D (pseudoephedrine / triprolidine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
