Applies to: Poly-Vita Drops with Iron (multivitamin with iron) and vadadustat
Consumer information for this interaction is not currently available.
ADJUST DOSING INTERVAL: Coadministration of vadadustat with oral products containing multivalent cations such as calcium, magnesium, or aluminum may significantly decrease the bioavailability of vadadustat. The mechanism of this interaction has not been fully described but may involve the formation of an insoluble complex or chelate with multivalent cations that is poorly absorbed from the gastrointestinal tract. According to product labeling, when non-iron-containing phosphate binders were coadministered-administered with vadadustat, the systemic exposure (AUC) and peak plasma concentration (Cmax) decreased by 55% and 52%, respectively.
MANAGEMENT: Vadadustat should be administered at least one hour before, or two hours after the administration of oral non-iron-containing phosphate binders or other medicinal products whose primary component consists of multivalent cations such as calcium, magnesium, or aluminum.
Drug and food interactions
multivitamin with iron food
Applies to: Poly-Vita Drops with Iron (multivitamin with iron)
Food may reduce the absorption and blood levels of multivitamin with iron. In addition, some oral medications can also interfere with multivitamin with iron absorption into the bloodstream, which may make the medication less effective in treating your condition. Likewise, multivitamin with iron may interfere with the absorption of other orally administered medications. You should take multivitamin with iron 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.

Applies to: vadadustat

MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.
MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.
