People with reduced kidney function may need a lower dose or longer time between doses, based on creatinine clearance (a kidney test). The label lists doses for 30 to 50, 5 to 29, and dialysis.
Section
2.3 Dosage Modifications in Patients with Renal Impairment, Table 4
Source text (exact source wording)
Table 4: Creatinine Clearance (mL/min) / Dose: > 50: See Usual Dosage. 30 to 50: 250 to 500 mg every 12 hours. 5 to 29: 250 to 500 mg every 18 hours. Patients on hemodialysis or Peritoneal dialysis: 250 to 500 mg every 24 hours (after dialysis). In patients with severe infections and severe renal impairment, a unit dose of 750 mg may be administered at the intervals noted above. Patients should be carefully monitored.
Liver
In stable cirrhosis the label reports no significant change in how the body handles ciprofloxacin. It has not been studied in acute liver failure.
Section
8.7 Hepatic Impairment
Source text (exact source wording)
In preliminary studies in patients with stable chronic liver cirrhosis, no significant changes in ciprofloxacin pharmacokinetics have been observed. The pharmacokinetics of ciprofloxacin in patients with acute hepatic insufficiency, have not been studied.
Elderly
The label says no dose change is needed for people over 65 with normal kidney function, but older people may have reduced kidney function, so care is needed in choosing the dose.
Section
8.5 Geriatric Use
Source text (exact source wording)
No alteration of dosage is necessary for patients greater than 65 years of age with normal renal function. However, since some older individuals experience reduced renal function by virtue of their advanced age, care should be taken in dose selection for elderly patients, and renal function monitoring may be useful in these patients
Missed dose
Take a missed dose as long as it is at least 6 hours before the next dose. If less than 6 hours remain, skip it. Never take double doses.
Section
2.4 Important Administration Instructions, Missed Doses (Medication Guide has matching text)
Source text (exact source wording)
If a dose is missed, it should be taken anytime but not later than 6 hours prior to the next scheduled dose. If less than 6 hours remain before the next dose, the missed dose should not be taken and treatment should be continued as prescribed with the next scheduled dose. Double doses should not be taken to compensate for a missed dose.
Overdose
In an overdose, kidney problems that go away have been reported. Doctors give supportive care and keep the person hydrated. Medication Guide: if you take too much, call your healthcare provider or get medical help right away. Poison control: 1-800-222-1222 (added per RxDiff rule; not from the label text).
Section
10 OVERDOSAGE; Medication Guide 'How should I take'
Source text (exact source wording)
In the event of acute overdosage, reversible renal toxicity has been reported in some cases. Empty the stomach by inducing vomiting or by gastric lavage. Observe the patient carefully and give supportive treatment, including monitoring of renal function, urinary pH and acidify, if required, to prevent crystalluria and administration of magnesium, aluminum, or calcium containing antacids which can reduce the absorption of ciprofloxacin. Adequate hydration must be maintained. Only a small amount of ciprofloxacin (less than 10%) is removed from the body after hemodialysis or peritoneal dialysis.
Storage
Store at room temperature, 20 to 25 degrees C (68 to 77 degrees F). Short trips between 15 and 30 degrees C (59 to 86 degrees F) are allowed. This is from the Aurobindo label; other labelers may differ.
Section
16 HOW SUPPLIED/STORAGE AND HANDLING
Source text (exact source wording)
Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [see USP Controlled Room Temperature].
Boxed warning
This medicine has a boxed warning, the FDA's strongest kind. Fluoroquinolones can cause serious, disabling reactions that may be permanent and can happen together: tendon swelling or rupture, nerve damage, and effects on the brain and mind. Stop it right away if any of these happen. It can make muscle weakness worse in myasthenia gravis, so it should be avoided in people with a known history. It should be saved for acute exacerbation of chronic bronchitis, acute uncomplicated cystitis and acute sinusitis only when there is no other treatment option.

Source text (exact source wording)
Clostridioides difficile (C. difficile)-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including ciprofloxacin, and may range in severity from mild diarrhea to fatal colitis.
It can lengthen the QT interval and cause heart rhythm problems.
Heading
5.12 Prolongation of the QT Interval
Source text (exact source wording)
Some fluoroquinolones, including ciprofloxacin, have been associated with prolongation of the QT interval on the electrocardiogram and cases of arrhythmia. Cases of torsade de pointes have been reported during postmarketing surveillance in patients receiving fluoroquinolones, including ciprofloxacin.
It can cause severe sunburn-like reactions. Avoid too much sun or UV light.
Heading
5.14 Photosensitivity/Phototoxicity
Source text (exact source wording)
Moderate to severe photosensitivity/phototoxicity reactions, the latter of which may manifest as exaggerated sunburn reactions (for example, burning, erythema, exudation, vesicles, blistering, edema) involving areas exposed to light (typically the face, “V” area of the neck, extensor surfaces of the forearms, dorsa of the hands), can be associated with the use of quinolones including ciprofloxacin after sun or UV light exposure. Therefore, avoid excessive exposure to these sources of light.
It can cause high or low blood sugar, mostly in people with diabetes who use diabetes medicine.
Heading
5.19 Blood Glucose Disturbances
Source text (exact source wording)
Fluoroquinolones, including ciprofloxacin, have been associated with disturbances of blood glucose, including symptomatic hyperglycemia and hypoglycemia, usually in diabetic patients receiving concomitant treatment with an oral hypoglycemic agent (for example, glyburide) or with insulin.
Pregnancy and breastfeeding
Source text (exact source wording)
Prolonged experience with ciprofloxacin in pregnant women over several decades, based on available published information from case reports, case control studies and observational studies on ciprofloxacin administered during pregnancy, have not identified any drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes (see Data). [8.1 Pregnancy] Because of the potential risk of serious adverse reactions in breastfed infants, including arthropathy shown in juvenile animal studies [see Use in Specific Populations (8.4), (Clinical Considerations)], for most indications a lactating woman may consider pumping and discarding breast milk during treatment with ciprofloxacin and an additional two days (five half-lives) after the last dose. Alternatively, advise a woman that breastfeeding is not recommended during treatment with ciprofloxacin and for an additional two days (five half-lives) after the last dose. [8.2 Lactation]
