• Infuse I.V. dose over at least 1 hour, using pump to ensure 1-hour duration.
☞ Know that too-rapid I.V. infusion increases risk of anaphylaxis and other adverse reactions.

Concurrent tube feedings, milk or yogurt (when consumed alone with ciprofloxacin): impaired drug absorption
Drug-herbs.Fennel: decreased drug absorption
• In patients with renal insufficiency, assess creatinine level before giving first dose and at least once a week during prolonged therapy. Monitor drug blood level closely.
☞ Watch for signs and symptoms of serious adverse reactions, including GI problems, jaundice, tendon problems, and hypersensitivity reactions.
• Tell patient to take drug with or without food at the same time each day.
• Advise patient not to take drug with dairy products or calcium-fortified juices alone or with caffeinated beverages.
• Advise patient to drink 8 oz of water every hour while awake to ensure adequate hydration.
☞ Instruct patient to stop taking drug and notify prescriber at first sign of burning, numbness, or tingling in hands or feet; yellow eyes or skin; unusual tiredness; persistent diarrhea; rash; or tendon pain, swelling, or inflammation.
• Advise patient to avoid excessive exposure to sun or ultraviolet light and to discontinue drug and notify prescriber if phototoxicity (burning, erythema, exudation, vesicles, blistering, edema) occurs.
• Advise patient taking hormonal contraceptives to use supplemental birth control method, such as condoms, because drug reduces contraceptive efficacy.
• Inform breastfeeding patient that drug is excreted in breast milk and can affect infant's bone growth. Advise her to consult prescriber before using drug.
• Teach patient how to use eye ointment or solution and tell patient not to touch eye dropper tip to any surface, to avoid contamination.
• Instruct patient how to use ear solution and to lie with affected ear upward for at least 1 minute after instilling solution.
• Caution patient with bacterial conjunctivitis not to wear contact lenses.
• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, and herbs mentioned above.
