Label text (1 paragraph)

Drug Interactions: Specific drug interaction studies have not been conducted with ophthalmic ciprofloxacin. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, enhance the effects of the oral anticoagulant, warfarin, and its derivatives and has been associated with transient elevations in serum creatinine in patients receiving cyclosporine concomitantly.

Supplement interactions

Dietary supplement interactions

3 noted
  • CalciumQuinolone antibiotics
    Simultaneous use of calcium supplements and quinolone antibiotics—such as ciprofloxacin (Cipro), gemifloxacin (Factive), and moxifloxacin (Avelox)—can reduce the absorption of quinolones. Taking the antibiotic 2 hours before or 2 hours after calcium supplements prevents this effect.
    Fact sheet, updated Jun 22, 2026
  • MagnesiumAntibiotics
    Magnesium can form insoluble complexes with tetracyclines, such as demeclocycline (Declomycin) and doxycycline (Vibramycin), and with quinolone antibiotics, such as ciprofloxacin (Cipro) and levofloxacin (Levaquin). These antibiotics should be taken at least 2 hours before or 4 to 6 hours after a magnesium-containing supplement.
    Fact sheet, updated Jan 6, 2026
  • ZincAntibiotics
    Both quinolone antibiotics (such as Cipro) and tetracycline antibiotics (such as Achromycin and Sumycin) might interact with zinc in the gastrointestinal tract, which could inhibit the absorption of both zinc and the antibiotic if they are taken at the same time. Taking the antibiotic at least 2 hours before or 4 to 6 hours after the zinc supplement minimizes this interaction.

Contraindications

CONTRAINDICATIONS A history of hypersensitivity to ciprofloxacin or any other component of the medication is a contraindication to its use. A history of hypersensitivity to other quinolones may also contraindicate the use of ciprofloxacin.

Reported adverse events (FAERS)

Liver injury (LiverTox)

A

Likelihood score A: Well established but uncommon cause of clinically apparent liver injury.

Ciprofloxacin is a second generation fluoroquinolone antibiotic that is widely used in the therapy of mild-to-moderate urinary and respiratory tract infections caused by susceptible organisms. Ciprofloxacin has been linked to rare but convincing instances of liver injury that can be severe and even fatal.

ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.

Pregnancy and lactation

Pregnancy

Pregnancy – Pregnancy Category C: Reproduction studies have been performed in rats and mice at doses up to six times the usual daily human oral dose and have revealed no evidence of impaired fertility or harm to the fetus due to ciprofloxacin. In rabbits, as with most antimicrobial agents, ciprofloxacin (30 and 100 mg/kg orally) produced gastrointestinal disturbances resulting in maternal weight loss and an increased incidence of abortion. No teratogenicity was observed at either dose. After intravenous administration, at doses up to 20 mg/kg, no maternal toxicity was produced and no embryotoxicity or teratogenicity was observed.

There are no adequate and well controlled studies in pregnant women. Ciprofloxacin Ophthalmic Solution, USP 0.3% should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Lactation

Nursing Mothers: It is not known whether topically applied ciprofloxacin is excreted in human milk; however, it is known that orally administered ciprofloxacin is excreted in the milk of lactating rats and oral ciprofloxacin has been reported in human breast milk after a single 500 mg dose. Caution should be exercised when Ciprofloxacin Ophthalmic Solution, USP 0.3% is administered to a nursing mother.

Breastfeeding (LactMed)

Amounts of ciprofloxacin in breastmilk are low. Fluoroquinolones such as ciprofloxacin have traditionally not been used in infants because of concern about adverse effects on the infants' developing joints. However, studies indicate little risk. The calcium in milk might decrease absorption of the small amounts of fluoroquinolones in milk, but insufficient data exist to prove or disprove this assertion. Use of ciprofloxacin is acceptable in nursing mothers with monitoring of the infant for possible effects on the gastrointestinal flora, such as diarrhea or candidiasis (thrush, diaper rash). Avoiding breastfeeding for 3 to 4 hours after a dose should decrease the exposure of the infant to ciprofloxacin in breastmilk. Maternal use of an ear drop or eye drop that contains ciprofloxacin presents negligible risk for the nursing infant.
