Interactions between your drugs

Moderate

promethazine aldesleukin

Applies to: phenylephrine / promethazine and aldesleukin

MONITOR: Sedatives, tranquilizers, muscle relaxants, antidepressants, and other central nervous system (CNS) depressants may have additive CNS-depressant effects with aldesleukin. Aldesleukin has been associated with CNS effects including depression, confusion, and drowsiness, which may progress to coma.

MANAGEMENT: Caution is advised if aldesleukin is used with sedatives, hypnotics, tranquilizers, or other CNS-active medications. Patients should be monitored for CNS depression and other CNS adverse effects. Treatment with aldesleukin should be discontinued if severe lethargy or somnolence develop.

Drug and food interactions

Moderate

promethazine food

Applies to: phenylephrine / promethazine

GENERALLY AVOID: Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment. Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines. The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.

MANAGEMENT: Patients should be advised to avoid alcohol during phenothiazine therapy.

Moderate

phenylephrine food

Applies to: phenylephrine / promethazine

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.
