Interactions between your drugs

Moderate

cholecalciferol apalutamide

Applies to: cholecalciferol / iron polysaccharide and Erleada (apalutamide)

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with CYP450 inducers such as rifampin, isoniazid, barbiturates, and certain anticonvulsants may decrease the pharmacologic effects of vitamin D analogs. These agents are thought to induce the hepatic conversion of vitamin D to inactive metabolites and have been shown to reduce circulating levels of active vitamin D, sometimes accompanied by reduced serum calcium and increased parathyroid hormone levels. Patients on long-term anticonvulsant therapy have occasionally developed osteomalacia, presumably due to interference with vitamin D and calcium metabolism. There have also been isolated reports of patients who responded poorly to vitamin D supplements during treatment with phenytoin and/or primidone.

MANAGEMENT: Patients receiving vitamin D analogs with CYP450 inducers should be monitored for potentially reduced vitamin D effects. Dosage adjustments may be necessary.

Drug and food interactions

Moderate

iron polysaccharide food

Applies to: cholecalciferol / iron polysaccharide

Food may reduce the absorption and blood levels of iron polysaccharide. In addition, some oral medications can also interfere with iron polysaccharide absorption into the bloodstream, which may make the medication less effective in treating your condition. Likewise, iron polysaccharide may interfere with the absorption of other orally administered medications. You should take iron polysaccharide on an empty stomach at least one hour before or two hours after a meal. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Talk to your doctor or pharmacist if you have questions about 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.
