Interactions between your drugs
ezetimibe rosuvastatin
Applies to: ezetimibe / rosuvastatin and ezetimibe / rosuvastatin
MONITOR: Coadministration with ezetimibe may rarely increase the risk of myopathy and serum transaminase elevations associated with HMG-CoA reductase inhibitors (i.e., statins). The mechanism of interaction is unknown. A case report describes two patients whose serum creatine kinase increased after ezetimibe was added to their statin therapy (atorvastatin and fluvastatin, respectively). One of the patients also developed myalgia and tendinopathy, which resolved promptly after withdrawal of both drugs. Statin therapy was subsequently reintroduced at the previous dosage without incident. In the other patient, serum creatine kinase returned to normal within 4 weeks after discontinuation of ezetimibe while the statin was continued. On the contrary, no cases of myopathy or tendinopathy occurred in a study of 33 hypercholesterolemic patients treated with ezetimibe and atorvastatin or simvastatin. There were also no reports of myopathy or significant increases in serum creatine kinase in a study of 32 subjects treated with ezetimibe and fluvastatin. In controlled clinical studies, the incidence of consecutive elevations (greater than 3 times the upper limit of normal) in serum transaminases was 1.3% for patients treated with ezetimibe in combination with a statin versus 0.4% for patients treated with a statin alone. These elevations were generally asymptomatic, not associated with cholestasis, and returned to baseline after discontinuation of therapy or with continued treatment.
MANAGEMENT: Until further information is available, use of a statin in combination with ezetimibe should be approached with caution. Patients should be advised to promptly report to their physician any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. The drugs should be discontinued if creatine kinase is markedly elevated in the absence of strenuous exercise or if myopathy is otherwise suspected or diagnosed. In addition, liver function tests should be performed at initiation of therapy and according to the recommendations of the HMG-CoA reductase inhibitor.

rosuvastatin ruxolitinib
Applies to: ezetimibe / rosuvastatin and ruxolitinib
MONITOR: Coadministration with ruxolitinib may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein efflux transporter and/or the breast cancer resistance protein (BRCP) in the intestine. The mechanism is decreased clearance via these routes due to inhibition by ruxolitinib. The clinical significance is unknown.
MANAGEMENT: Caution is advised if ruxolitinib must be used concurrently with medications that are substrates of the P-glycoprotein efflux transporter and/or the breast cancer resistance protein (BRCP) , particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever ruxolitinib is added to or withdrawn from therapy. The interaction may possibly be avoided or minimized if the doses of the affected medications are separated for as long as possible.

Drug and food interactions
ruxolitinib food
Applies to: ruxolitinib
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ruxolitinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits.
MANAGEMENT: Patients treated with ruxolitinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Ruxolitinib may be administered with or without food.
