Zinc Sulfate and Delafloxacin Interaction
Drug interaction information between Zinc Sulfate and Delafloxacin.
Zinc Sulfate and Delafloxacin have a documented minor interaction in FDA labeling.
FDA drug labeling documents a minor-severity interaction between Zinc Sulfate and Delafloxacin. Major interactions are generally avoided, moderate ones may need monitoring or a dose adjustment, and minor ones are usually low-risk. This page shows the documented mechanism and guidance. Label-documented interactions are not a complete safety review, so always confirm your own medications with a pharmacist or doctor. Educational information, not medical advice.
How They Interact
Zinc binds to the antibiotic in your stomach, which stops the body from absorbing it properly. This can make the antibiotic much less effective at fighting your infection.
What To Do
Do not take these two medications at the same time. Your doctor or pharmacist can help you create a schedule to space them out safely.
FDA Label Information
Oral administration of BAXDELA with antacids containing aluminum or magnesium, with sucralfate, with metal cations such as iron, or with multivitamins containing iron or zinc, or with formulations containing divalent and trivalent cations such as didanosine buffered tablets for oral suspension or the pediatric powder for oral solution, may substantially interfere with the absorption of BAXDELA, resulting in systemic concentrations considerably lower than desired.
Zinc Sulfate Also Interacts With
- Baloxavir Marboxil moderate
- Levofloxacin minor
- Moxifloxacin minor
- Tetracycline minor
Frequently Asked Questions
Can I take Zinc Sulfate and Delafloxacin together?

Zinc binds to the antibiotic in your stomach, which stops the body from absorbing it properly. This can make the antibiotic much less effective at fighting your infection.
Understanding the Zinc Sulfate and Delafloxacin Interaction
FDA-approved prescribing information for these two drugs flags their combination as a minor-severity interaction. Zinc Sulfate belongs to the Mineral Supplement class and Delafloxacin belongs to the Fluoroquinolone Antibiotic class - two categories that can collide when co-prescribed. The mechanism described in FDA labeling is: Zinc binds to the antibiotic in your stomach, which stops the body from absorbing it properly. Severity tiers matter: major flags generally advise avoidance, moderate flags often require monitoring or dose adjustment, and minor flags may only call for awareness.
Context around a specific patient determines real-world impact. Zinc Sulfate has 5 total documented interactions on file in this dataset, and Delafloxacin has 2. Each additional medication compounds the interaction surface, which is why pharmacists run full-profile checks rather than evaluating one pair at a time. FDA-derived guidance for this pair is: Do not take these two medications at the same time. Timing of doses, renal and hepatic function, age, and other concurrent prescriptions all shape whether a labeled interaction matters clinically.
An interaction flag is not a verdict. A large share of labeled interactions are managed routinely in clinical practice, the fix may be as simple as spacing doses or adding a monitoring test. Others require the prescriber to choose a different medication entirely. This page surfaces FDA-sourced labeling and openFDA data for educational purposes only; it is not medical advice and cannot account for your full clinical picture. Never start, stop, or adjust either Zinc Sulfate or Delafloxacin based on a web page, speak with your prescriber or pharmacist before making any change.
