Interactions between your drugs

Major

amLODIPine encorafenib

Applies to: Amturnide (aliskiren / amlodipine / hydrochlorothiazide) and encorafenib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of calcium channel blockers, the majority of which are primarily metabolized by the isoenzyme. Undetectable plasma levels have been reported for some calcium blockers when given orally.

MANAGEMENT: Concomitant use of calcium channel blockers with potent CYP450 3A4 inducers should generally be avoided. If coadministration is necessary, pharmacologic response should be monitored more closely following the initiation or discontinuation of the CYP450 3A4 inducer, and the CCB dosage adjusted accordingly.

aliskiren food

Applies to: Amturnide (aliskiren / amlodipine / hydrochlorothiazide)

Food can affect the absorption of aliskiren from the intestine. Therefore, you should take aliskiren at the same time each day exactly as prescribed by your doctor. You may take aliskiren with or without food, but take it the same way every time. This will help keep blood levels and effects of the medication steady. You should avoid drinking orange, apple, or grapefruit juice as much as possible during treatment with aliskiren. Studies have shown that drinking these juices regularly or within a short period before or after a dose of aliskiren can interfere with the absorption of the medication.
