Can I Take These?

Can You Take Ciprofloxacin and Zinc Together?

Zinc can reduce how much ciprofloxacin your body absorbs -- NIH guidance recommends spacing them several hours apart.

Use cautionEvidence: Moderate

What the interaction means

The NIH Office of Dietary Supplements' zinc fact sheet states: "Both quinolone antibiotics (such as Cipro) and tetracycline antibiotics (such as Achromycin and Sumycin) might reduce the amount of both zinc and the antibiotic that your body absorbs. To help avoid this interaction, take the antibiotic at least 2 hours before, or 4 to 6 hours after, taking a zinc supplement."

Why it may happen

Zinc and quinolone antibiotics such as ciprofloxacin can bind together in the gastrointestinal tract, reducing absorption of both the mineral and the antibiotic.

Practical context

The source's own recommended spacing is asymmetric -- at least 2 hours before the zinc supplement, or 4 to 6 hours after it -- rather than a single symmetric interval, so no single spacing-minutes figure is published here; follow the asymmetric guidance above and any specific instructions from the prescribing clinician or pharmacist.
