Interactions between your drugs
black cohosh ceritinib
Applies to: Menopause Support (black cohosh) and ceritinib
GENERALLY AVOID: Concomitant use of black cohosh (Cimicifuga racemosa rhizome) with other agents that are known to induce hepatotoxicity may theoretically increase the risk of liver injury. Black cohosh has been suspected in rare cases of liver toxicity ranging from abnormal liver function tests and jaundice to various forms of hepatitis and hepatic failure requiring transplantation. The onset has typically been within the first 3 months after initiation of black cohosh. Although approximately half of the cases resulted in hospitalization, most improved or resolved following discontinuation of the product. Many of the cases were not well documented with respect to the specific herbal formulation and dose used or timeframe of treatment in relation to onset of reaction, or they were complicated by multiple confounding factors. Some of the cases also involved products containing multiple herbal or other medicinal substances. Nevertheless, the European Medicines Agency (EMEA) and the Committee on Herbal Medicinal Products (HMPC) reviewed 42 such cases and released an assessment statement in 2006 indicating a potential connection between products containing Cimicifuga racemosa rhizome and human hepatotoxicity. The Medicines and Healthcare products Regulatory Agency (MHRA) in the U.K. also issued an assessment report supporting a causal association after reviewing data from over 40 cases received through their reporting system and similar systems in other countries, as well as in the published literature. Hepatotoxicity warnings are currently required on products containing black cohosh marketed in many European countries and Australia.
MANAGEMENT: Until more information is available, patients should consider avoiding the use of black cohosh if they are receiving other potentially hepatotoxic agents (e.g., acetaminophen; alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; cyclosporine (high dosages); disulfiram; endothelin receptor antagonists; interferons; ketolide and macrolide antibiotics; kinase inhibitors; minocycline; nonsteroidal anti-inflammatory agents; nucleoside reverse transcriptase inhibitors; proteasome inhibitors; retinoids; sulfonamides; tamoxifen; thiazolidinediones; tolvaptan; vincristine; zileuton; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, lomitapide, mipomersen, niacin, and statins; other herbals and nutritional supplements such as chaparral, comfrey, DHEA, kava, pennyroyal oil, and red yeast rice). Patients should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, right upper quadrant pain, dark urine, pale stools, and jaundice.

Drug and food interactions
ceritinib food
Applies to: ceritinib
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ceritinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Because ceritinib is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death. Other, more common side effects such as diarrhea, nausea, vomiting, abdominal pain, hyperglycemia, and bradycardia may also increase.
ADJUST DOSING INTERVAL: Food increases the oral bioavailability of ceritinib. The mechanism of interaction is unknown. Compared to the fast state, administration of a single 500 mg dose of ceritinib with a high-fat meal (approximately 1000 calories; 58 grams of fat) increased ceritinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 41% and 73%, respectively, and administration with a low-fat meal (approximately 330 calories; 9 grams of fat) increased ceritinib Cmax and AUC by 43% and 58%, respectively. A dose of 600 mg or higher taken with a meal is expected to produce systemic exposure exceeding that from a 750 mg dose taken in the fasted state, which may lead to increased adverse effects.
MANAGEMENT: Patients treated with ceritinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Ceritinib should be administered on an empty stomach (i.e., avoid administration within 2 hours of a meal).
