Interactions between your drugs

Moderate

nintedanib encorafenib

Applies to: nintedanib and encorafenib

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with encorafenib may increase the plasma concentrations of drugs that are substrates of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), organic cation transporter (OCT2), organic anion transporter (OAT1, OAT3), organic anion transporting polypeptide (OATP1B1, OATP1B3), or uridine diphosphate glucuronosyltransferase (UGT) 1A1. In in vivo studies, encorafenib has been shown to be an inhibitor of OATP1B1, 1B3, and BCRP. In vitro studies have demonstrated it to be an inhibitor of OCT2, OAT1, OAT3, and P-gp at expected clinical concentrations as well as a potent, reversible inhibitor of UGT1A1. Administration of a single dose of rosuvastatin, an OATP1B1, OATP1B3 and BCRP substrate, after repeated administration of encorafenib 450 mg once daily and binimetinib 45 mg twice daily, resulted in increased systemic exposure (AUC) and peak plasma concentration (Cmax) of rosuvastatin by approximately 1.6 fold and 2.7 fold respectively.

MANAGEMENT: Caution is advised if encorafenib must be used concomitantly with drugs that are substrates of the affected transporters or UGT1A1, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever encorafenib is added to or withdrawn from therapy.

Drug and food interactions

Major

encorafenib food

Applies to: encorafenib

You should preferably avoid consumption of grapefruit and grapefruit juice while taking encorafenib. Grapefruit and grapefruit juice can significantly increase the blood levels of encorafenib. This may increase the risk of serious side effects such as bleeding complications, eye and vision problems, liver problems, irregular heart rhythm, and development of new skin cancers. Talk to your doctor if you have any questions or concerns. 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.

Moderate

nintedanib food

Applies to: nintedanib

Grapefruit juice and Seville orange juice can increase the blood levels of nintedanib. This may increase the risk and/or severity of side effects such as liver problems, diarrhea, nausea, vomiting, stomach or intestinal wall perforation, bleeding, and cardiovascular problems such as heart attack, chest pain, or stroke. It is best to avoid or minimize the consumption of Seville oranges, Seville orange juice, grapefruit, and grapefruit juice during treatment. You should take nintedanib with food and swallow it whole with water. Taking nintedanib with food may help with absorption of the medication and reduce gastrointestinal side effects. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Multikinase inhibitors

Therapeutic duplication

The recommended maximum number of medicines in the 'multikinase inhibitors' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'multikinase inhibitors' category:

  • encorafenib
  • nintedanib

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

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.
