Interactions between your drugs

Moderate

dextromethorphan teclistamab

Applies to: PediaCare Children's Multi-Symptom Cold (dextromethorphan / phenylephrine) and teclistamab

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with teclistamab may increase the plasma concentrations of drugs that are substrates of CYP450 isoenzymes. Initiation of teclistamab treatment causes transient release of cytokines that may suppress CYP450 isoenzymes, although the potential for interaction has not been studied. According to the manufacturer, the highest drug-drug interaction risk would be from the start of teclistamab therapy (including the initial step-up dosing schedule) up to 7 days after the first treatment dose (considered to be the first weekly dose administered after the completion of the step-up dosing schedule), as well as during and after cytokine release syndrome.

MANAGEMENT: Caution is advised when teclistamab is coadministered with drugs that are metabolized by CYP450 isoenzymes, particularly those with a narrow therapeutic range, where minimal changes to concentration may lead to significant adverse reactions, such as carbamazepine, colchicine, cyclosporine, disopyramide, phenytoin, quinidine, theophylline, warfarin, macrolide immunosuppressants, vinca alkaloids, and some narcotic analgesics. Clinical and/or laboratory monitoring are recommended, particularly at the initial phase of treatment with teclistamab as well as during and after cytokine release syndrome, and the dosage(s) of the CYP450 substrate(s) adjusted accordingly.

Drug and food interactions

Moderate

dextromethorphan food

Applies to: PediaCare Children's Multi-Symptom Cold (dextromethorphan / phenylephrine)

Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Switch to professional interaction data

Moderate

phenylephrine food

Applies to: PediaCare Children's Multi-Symptom Cold (dextromethorphan / phenylephrine)

Consumer information for this interaction is not currently available.

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.

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.
