MONITOR: Alcohol may decrease the antidiuretic effect of vasopressin. Clinical studies found that plasma vasopressin levels often decrease during alcohol consumption and increase upon cessation of consumption. In addition, alcoholics were found to have a more pronounced decrease in plasma vasopressin levels when drinking and suppressed vasopressin levels even during alcohol withdrawal as compared to non-alcoholic individuals. The mechanism of this interaction is not fully understood.

MANAGEMENT: Patients should be advised to abstain from alcohol during vasopressin treatment. Hemodynamic monitoring is suggested for patients known to drink alcohol while receiving vasopressin.

Moderate

phenylephrine food

Applies to: MontePhen (guaifenesin / phenylephrine)

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.

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.
