Interactions between your drugs
multivitamin, prenatal patiromer
Applies to: Mynatal PN (multivitamin, prenatal) and patiromer
ADJUST DOSING INTERVAL: Simultaneous administration of cation-donating preparations may reduce the potassium exchange capability of cation-exchange resins due to binding of the cation to the resin.
MANAGEMENT: Patients should consider separating the times of administration of the cation-exchange resin and any cation-donating preparation (e.g., mineral supplements; antacids; products containing antacids such as didanosine buffered tablets or pediatric oral solution) by several hours if possible.

Drug and food interactions
multivitamin, prenatal food
Applies to: Mynatal PN (multivitamin, prenatal)
ADJUST DOSING INTERVAL: Concomitant use of some oral medications may reduce the bioavailability of orally administered iron, and vice versa.
Food taken in conjunction with oral iron supplements may reduce the bioavailability of the iron. However, in many patients intolerable gastrointestinal side effects occur necessitating administration with food.
MANAGEMENT: Ideally, iron products should be taken on an empty stomach (i.e., at least 1 hour before or 2 hours after meals), but if this is not possible, administer with meals and monitor the patient more closely for a subtherapeutic effect. Some studies suggest administration of iron with ascorbic acid may enhance bioavailability. In addition, administration of oral iron products and some oral medications should be separated whenever the bioavailability of either agent may be decreased. Consult the product labeling for specific separation times and monitor clinical responses as appropriate.

patiromer food
Applies to: patiromer
ADJUST DOSING INTERVAL: Patiromer can bind to some orally administered drugs, which may decrease their gastrointestinal absorption and reduce their effectiveness. According to the manufacturer, out of 28 drugs that were tested in in vitro binding studies, 14 did not show an interaction with patiromer (acetylsalicylic acid, allopurinol, amoxicillin, apixaban, atorvastatin, cephalexin, digoxin, glipizide, lisinopril, phenytoin, riboflavin, rivaroxaban, spironolactone, and valsartan). Twelve of the 14 drugs that did show an in vitro interaction were subsequently tested in in vivo studies with healthy volunteers, which revealed no changes in systemic exposure when coadministered with patiromer (amlodipine, cinacalcet, clopidogrel, furosemide, lithium, metoprolol, trimethoprim, verapamil, and warfarin). Patiromer was found to decrease systemic exposure of coadministered ciprofloxacin, levothyroxine, and metformin. However, no significant interaction occurred when patiromer and these drugs were dosed 3 hours apart.
MANAGEMENT: Patiromer should be administered with food at least 3 hours before or 3 hours after other oral medications. Alternatives to patiromer or the other medications should be considered if adequate dosing separation is not possible. Otherwise, clinical response and/or blood levels should be monitored where possible.
