Promacta (Eltrombopag Tablets) and Multivitamins with minerals

Eltrombopag and multivitamin with minerals should not be taken orally at the same time. Products that contain aluminum, calcium, iron, magnesium, zinc or other minerals may interfere with the absorption of eltrombopag into the bloodstream and reduce its effectiveness. You should take eltrombopag on an empty stomach at least 2 hours before or 4 hours after multivitamin with minerals. Talk to a healthcare professional if you are not sure whether a product contains something that could potentially interact with your medication or if you have questions on 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.

ADJUST DOSING INTERVAL: Products containing aluminum, calcium, iron, magnesium, zinc and other polyvalent cations such as antacids or mineral supplements can significantly reduce the gastrointestinal absorption of eltrombopag due to chelation. In one clinical trial, administration of a single 75 mg dose of eltrombopag with an antacid containing 1524 mg aluminum hydroxide and 1425 mg magnesium carbonate resulted in an approximately 70% decrease in eltrombopag peak plasma concentration (Cmax) and systemic exposure (AUC).

MANAGEMENT: Eltrombopag should be taken on an empty stomach at least 2 hours before or 4 hours after oral medications that contain antacids (e.g., didanosine buffered tablets or pediatric oral solution), aluminum, calcium, iron, magnesium, zinc or other polyvalent cations.
