Ciprofloxacin - Fluoroquinolones Antibiotic Uses, MOA, Detail Dose, Drug Drug Interactions, Side effects and ADRs

What is Ciprofloxacin?

Ciprofloxacin is a fluoroquinolone (flor-o-KWIN-o-lone) antibiotic, it is used to treat different types of bacterial infections. It is also used to treat people who have been exposed to anthrax or certain types of plague. Ciprofloxacin extended-release is only approved for use in adults.

Fluoroquinolone antibiotics can cause serious or disabling side effects that may not be reversible

Ciprofloxacin should be used only for infections that cannot be treated with a safer antibiotic.

Warnings

Ciprofloxacin can cause serious side effects, including tendon problems, nerve damage, serious mood or behavior changes, or low blood sugar.

Stop using ciprofloxacin and call your doctor at once if you have: headache, hunger, irritability, numbness, tingling, burning pain, confusion, agitation, paranoia, problems with memory or concentration, thoughts of suicide, or sudden pain or movement problems in any of your joints.

In rare cases, ciprofloxacin may cause damage to your aorta, which could lead to dangerous bleeding or death. Get emergency medical help if you have severe and constant pain in your chest, stomach, or back.

You may not be able to use this medicine if you have a muscle disorder. Tell your doctor if you have a history of myasthenia gravis.

Before taking this medicine

You should not use ciprofloxacin if you are allergic to it, or if:

  • you also take tizanidine; or

  • you are allergic to other fluoroquinolones (levofloxacin, moxifloxacin, norfloxacin, ofloxacin).

Ciprofloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles' tendon of the heel. This can happen during treatment or several months after you stop taking ciprofloxacin. Tendon problems may be more likely in children and older adults, or people who use steroid medicine or have had an organ transplant.

To make sure ciprofloxacin is safe for you, tell your doctor if you have ever had:

  • arthritis or problems with your tendons, bones or joints (especially in children);

  • diabetes, low blood sugar;

  • nerve problems;

  • an aneurysm or blood circulation problems;

  • heart problems, or a heart attack;

  • muscle weakness, myasthenia gravis;

  • liver or kidney disease;

  • a seizure, head injury, or brain tumor;

  • trouble swallowing pills;

  • long QT syndrome (in you or a family member); or

  • low levels of potassium in your blood (hypokalemia).

Do not give this medicine to a child without medical advice.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant.

You should not breastfeed while taking ciprofloxacin and for 2 days after your last dose. Ask your doctor about breastfeeding if you take this medicine for anthrax exposure.

How should I take ciprofloxacin?

Take ciprofloxacin exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Take ciprofloxacin at the same time each day, with or without food.

Shake the oral suspension (liquid) for 15 seconds before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon). Do not give ciprofloxacin oral suspension through a feeding tube.

Swallow the extended-release tablet whole and do not crush, chew, or break it.

Drink plenty of liquids while you are taking this medicine.

Use ciprofloxacin for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Ciprofloxacin will not treat a viral infection such as the flu or a common cold.

Do not share this medicine with another person.

Store at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze. Throw away any unused liquid after 14 days.

What to avoid:

Do not take ciprofloxacin with dairy products such as milk or yogurt, or with calcium-fortified juice. You may eat or drink these products with your meals, but do not use them alone when taking this medicine.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor before using anti-diarrhea medicine.

Ciprofloxacin could make you sunburn more easily. Avoid sunlight or tanning beds. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors. Tell your doctor if you have severe burning, redness, itching, rash, or swelling after being in the sun.

Avoid driving or hazardous activity until you know how ciprofloxacin will affect you. Your reactions could be impaired.

Ciprofloxacin side effects

Get emergency medical help if you have signs of an allergic reaction to ciprofloxacin (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling).

Ciprofloxacin can cause serious side effects, including tendon problems, damage to your nerves (which may be permanent), serious mood or behavior changes (after just one dose), or low blood sugar (which can lead to coma).

Stop taking this medicine and call your doctor at once if you have:

  • low blood sugar - headache, hunger, irritability, dizziness, nausea, fast heart rate, or feeling shaky;

  • nerve damage symptoms - numbness, tingling, burning pain in your hands, arms, legs, or feet:

  • serious mood or behavior changes - nervousness, confusion, agitation, paranoia, hallucinations, memory problems, trouble concentrating, thoughts of suicide; or

  • signs of tendon rupture - sudden pain, swelling, bruising, tenderness, stiffness, movement problems, or a snapping or popping sound in any of your joints (rest the joint until you receive medical care or instructions).

In rare cases, ciprofloxacin may cause damage to your aorta, the main blood artery of the body. This could lead to dangerous bleeding or death. Get emergency medical help if you have severe and constant pain in your chest, stomach, or back.

Also, stop using this medicine and call your doctor at once if you have:

  • severe stomach pain, diarrhea that is watery or bloody;

  • fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out);

  • any skin rash, no matter how mild;

  • muscle weakness, breathing problems;

  • little or no urination;

  • jaundice (yellowing of the skin or eyes); or

  • increased pressure inside the skull - severe headaches, ringing in your ears, dizziness, nausea, vision problems, pain behind your eyes.

Common ciprofloxacin side effects may include:

  • nausea, vomiting, diarrhea, stomach pain;

  • headache; or

  • abnormal liver function tests.

What other drugs will affect ciprofloxacin?

Some medicines can make ciprofloxacin much less effective when taken at the same time. If you take any of the following medicines, take your ciprofloxacin dose 2 hours before or 6 hours after you take the other medicine.

  • the ulcer medicine sucralfate, or antacids that contain calcium, magnesium, or aluminum (such as Maalox, Milk of Magnesia, Mylanta, Pepcid Complete, Rolaids, Tums, and others);

  • Bacteremia: At least 14 days
  • Gastroenteritis: 7 to 10 days
  • Recurrent infections: 2 to 6 weeks
Comments:
  • Recommended as preferred therapy (if MIC is less than 0.12 mcg/mL) to shorten duration of illness and to possibly prevent spread to others
  • Increased resistance of Shigella to fluoroquinolones reported in the US; treatment of Shigella with fluoroquinolones should be avoided if ciprofloxacin MIC is 0.12 mcg/mL or greater, even if isolate identified as sensitive by laboratory.
  • Current guidelines should be consulted for additional information.

Usual Pediatric Dose for Salmonella Enteric Fever

US CDC, NIH, and HIVMA/IDSA Recommendations for HIV-Infected Adolescents:

  • IV: 400 mg IV every 12 hours
  • Oral: 500 to 750 mg orally every 12 hours
Duration of Salmonellosis Therapy:
For gastroenteritis without bacteremia:
  • If CD4 count at least 200 cells/mm3: 7 to 14 days
  • If CD4 count less than 200 cells/mm3: 2 to 6 weeks

For gastroenteritis with bacteremia:

Precautions

US BOXED WARNING:
SERIOUS SIDE EFFECTS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CNS EFFECTS, AND EXACERBATION OF MYASTHENIA GRAVIS:

  • Fluoroquinolones (including this drug) have been associated with disabling and potentially irreversible serious side effects that have occurred together (including tendinitis and tendon rupture, peripheral neuropathy, CNS effects). This drug should be discontinued immediately and use of fluoroquinolones (including this drug) should be avoided in patients with any of these serious side effects.
  • Fluoroquinolones (including this drug) may exacerbate muscle weakness in patients with myasthenia gravis. This drug should be avoided in patients with known history of myasthenia gravis.
  • Since fluoroquinolones (including this drug) have been associated with serious side effects, this drug should be reserved for use in patients with no alternative treatment options for acute exacerbation of chronic bronchitis, acute uncomplicated cystitis/uncomplicated urinary tract infections (acute cystitis), or acute sinusitis.
CONTRAINDICATIONS:
History of hypersensitivity to the active component, other quinolones, or any of the ingredients; coadministration with tizanidine

Extended-release tablets: Safety and efficacy have not been established in patients younger than 18 years.

Consult WARNINGS section for additional precautions.

  • Proquin(R) XR: Data not available
Pediatric Patients: Data not available

Comments:
  • Dose should be administered after dialysis.

Other Comments

Administration advice:

  • Infuse IV doses over at least 60 minutes; slow infusion of dilute solution into larger vein will minimize patient discomfort and reduce risk of venous irritation.
  • May switch from IV to oral therapy when clinically indicated at the physician's discretion
  • May administer immediate-release tablets and oral suspension and Cipro(R) XR without regard to meals; administer Proquin(R) XR with a main meal, preferably the evening meal.
  • In general, continue this drug (immediate-release) for at least 2 days after signs/symptoms of infection have disappeared, except for inhalation anthrax (postexposure).
  • Swallow extended-release tablets whole; do not split, crush, or chew.
  • Shake the oral suspension vigorously for about 15 seconds before each dose.
  • Use the co-packaged graduated spoon to administer the oral suspension; after use, clean under running water with dish detergent and dry thoroughly.
  • Swallow the microcapsules in the oral suspension whole; do not chew. May take water afterwards
  • Do not administer the oral suspension through feeding or nasogastric tubes.
  • May administer oral doses with meals that include dairy products (like milk, yogurt) or calcium-fortified juices; do not administer with such products alone.
  • Administer oral doses at least 2 hours before or 6 hours after magnesium/aluminum antacids, polymeric phosphate binders (e.g., sevelamer, lanthanum carbonate), sucralfate, buffered didanosine, other highly buffered drugs, or other products containing calcium, iron, or zinc; administer Proquin(R) XR at least 4 hours before or 2 hours after such products.
  • To determine dose and duration, consider the nature and severity of the infection, pathogen susceptibility, integrity of patient's host-defense mechanisms, and renal and liver function status; may administer this drug to adult patients when clinically indicated at physician's discretion.
  • Maintain adequate hydration of patients to prevent formation of highly-concentrated urine.

Storage requirements:

  • IV injection: Store between 5C to 25C (41F to 77F); protect from light; avoid excessive heat; protect from freezing.
  • Oral formulations: Store at 20C to 25C (68C to 77F); excursions permitted to 15C to 30C (59F to 86F). Protect oral suspension from freezing; discard reconstituted suspension after 14 days.
Reconstitution/preparation techniques:
  • The manufacturer product information should be consulted.
General:
  • Unless otherwise specified, the dose provided is for immediate-release formulations.
  • In patients younger than 18 years, this drug is only US FDA-approved for complicated UTIs, prevention of inhalation anthrax (postexposure), and plague.
  • Culture and susceptibility information should be considered when selecting/modifying antibacterial therapy or, if no data are available, local epidemiology and susceptibility patterns may be considered when selecting empiric therapy.
  • Appropriate culture and susceptibility testing recommended before therapy to isolate and identify infecting organisms and to establish susceptibility to this drug. Therapy may be started before test results are known; appropriate therapy should be continued when results are available.
  • If suspected pathogens include anaerobic organisms, appropriate therapy should be used.
  • Some isolates of P aeruginosa may develop resistance relatively quickly during therapy.
  • The 10% oral suspension is not appropriate for children less than 13 kg.
  • Nothing should be added to the mixed final oral suspension.
  • The extended-release tablets are not interchangeable with immediate-release tablets or oral suspension; extended-release tablets made by different manufacturers are not interchangeable due to different pharmacokinetics (e.g., Cipro[R] XR and Proquin[R] XR).

Monitoring:
