Interactions between your drugs

Moderate

ivabradine tarlatamab

Applies to: ivabradine and tarlatamab

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with tarlatamab may increase the plasma concentrations of drugs that are substrates of CYP450 3A4 isoenzymes. Initiation of tarlatamab 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 during and for up to 14 days after the occurrence of cytokine release syndrome.

MANAGEMENT: Caution is advised when tarlatamab 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 during and after cytokine release syndrome, and individual product labeling for the CYP450 substrate(s) should be consulted for specific dosage adjustment recommendations.

Drug and food interactions

Major

ivabradine food

Applies to: ivabradine

Do not consume grapefruit or grapefruit juice during treatment with ivabradine. Grapefruit juice can significantly increase the blood levels and effects of ivabradine, which may result in excessive slowing of heart rate or other conduction disturbances. Talk to your doctor if you have any questions or concerns. Let your doctor know if you experience significant decreases in heart rate or symptoms such as dizziness, fatigue, or low blood pressure. Also seek medical attention if you develop heart palpitations, chest pressure, or worsened shortness of breath, as these may be symptoms of atrial fibrillation caused by ivabradine. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
