The short answer
Aluminum-containing oral products can interfere with delafloxacin tablet absorption. For the products named in the label, take delafloxacin at least 2 hours before or 6 hours after the mineral product. A two-hour gap in either direction would miss part of the instruction.
What this answer covers
Oral delafloxacin meglumine tablets with aluminum-containing oral antacids. The interaction concerns absorption in the digestive tract, not every route or trace exposure.
- Supplement or preparation
- Aluminum
- Medication ingredient
- delafloxacin
Which products are covered?
The delafloxacin instructions name aluminum-containing antacids. That means medicines such as an aluminum antacid should be assessed by their actual formulation. Trace aluminum in food or a skin product is a different exposure, and sucralfate, also named in the label, should retain its identity as a separate aluminum-containing medicine.
How do I arrange the two doses?
If delafloxacin is taken first, wait at least 2 hours before the aluminum product. If the mineral is first, wait at least 6 hours before delafloxacin. The order matters. Ask the pharmacist to fit repeated supplement or antacid doses around the prescribed antibiotic schedule instead of using an interval remembered from another antibiotic.
How much does the interaction change treatment?
The current label warns that overlapping oral products can leave less antibiotic available in the body, but it does not quantify a mineral-only effect in a human trial. A percentage measured with ciprofloxacin or moxifloxacin cannot be assigned to delafloxacin. The precaution supports following the label schedule, without predicting that an individual infection will fail treatment.
Does this change my need for the mineral?
A scheduling precaution does not establish that the antibiotic depletes a nutrient or makes a prescribed supplement unnecessary. Keep the reason for treatment, exact product and dose available when discussing a plan. Tablets and intravenous delafloxacin have different administration considerations; an oral spacing instruction should not be used to manage an infusion.
Evidence and practical considerations
Absorption & effectiveness
Aluminum-containing oral products can interfere with delafloxacin tablet absorption. For the products named in the label, take delafloxacin at least 2 hours before or 6 hours after the mineral product. A two-hour gap in either direction would miss part of the instruction.
- Exact scope
- aluminum-containing oral antacids with oral delafloxacin meglumine tablets, 450 mg active delafloxacin equivalent
- Medication form and route
- oral
- Timing or duration
- Precaution at each overlapping oral dose throughout the antibiotic course; mineral-specific clinical duration and effect magnitude are not established.
What remains uncertain
- Exact-drug regulatory guidance, without an independently inspected human mineral-only delafloxacin trial. No magnitude of treatment failure, nutrient depletion or all-salt equivalence is established.
Factors that may matter: exact salt and dose; order and interval between oral doses; combination-product ingredients; oral versus nonoral route.

Population: Adults prescribed oral BAXDELA tablets; injection instructions kept separate.
Take tablets at least 2 hours before or 6 hours after magnesium/aluminum antacids, iron and zinc/iron multivitamins. Patient instructions also name Mg, Al, Fe and Zn products. Tablets can be taken with or without food. Calcium/magnesium solutions are prohibited in the same IV line; that is not an oral calcium trial.
How this applies: Explicit active-moiety equivalence supports oral meglumine tablets under parent RxCUI 1927663. Oral and IV instructions are not interchangeable. Article-specific counterparty: aluminum-containing oral antacids.
No individual mineral effect size or direct oral copper/calcium trial is supplied. Label guidance is not an independent human interaction experiment.
