What is ciprofloxacin?

Ciprofloxacin, also known as ciprofloxacin hydrochloride, belongs to a class of drugs called fluoroquinolone antibiotics. Ciprofloxacin is a bactericidal antibiotic, which means it kills bacteria rather than just stopping their growth.

It is a generic drug and is considered to be safe and effective. This medicine is a suitable treatment for patients with infections caused by multiple types of bacteria or those at risk of Gram-negative bacterial infections [1].

How ciprofloxacin works

Ciprofloxacin inhibits two vital bacterial enzymes: DNA gyrase (topoisomerase II) and topoisomerase IV. The medicine blocks DNA gyrase, which is an enzyme that introduces negative supercoils into bacterial DNA, stopping normal DNA replication and transcription [2].

It also inhibits topoisomerase IV, an enzyme critical for separating replicated chromosomal DNA into daughter cells during cell division.

The broad-spectrum activity and good tissue penetration make Ciprofloxacin a powerful antibiotic, but the potential for resistance highlights the need for caution and appropriate use.

What is ciprofloxacin used for?

Ciprofloxacin is used to treat bacterial infections in adults. This includes:

  • Urinary tract infections (UTIs)
  • Gonorrhea (a sexually transmitted infection)
  • Sinus infection
  • Gastrointestinal and abdominal infection
  • Chronic prostatitis
  • Joint and bone infections
  • Lower respiratory tract infections
  • Skin infections
  • Typhoid fever
  • Diarrhea
  • Plague

This medication is recommended for children in certain situations to treat bacterial infections. They are:

  • Urinary tract infections in children ages 1 year or older.
  • Plague (children of any age).
  • Prevention of infections from inhaled anthrax in children of any age.

Important safety warning (FDA and MHRA)

Ciprofloxacin carries the FDA's strongest warning for serious adverse reactions, which include tendinitis, tendon rupture, peripheral neuropathy (nerve damage), and central nervous system effects. It also warns that systemic fluoroquinolones can cause permanent peripheral neuropathy (tingling, burning, numbness, or weakness in the arms/legs) and marked disturbances in blood glucose levels.

It highlights an increased risk of rare but life-threatening tears (dissections) in the aorta (the main blood vessel of the body), particularly in older patients or those having a history of blockages/aneurysms.

The MHRA warns that fluoroquinolones can cause long-lasting, disabling, and potentially irreversible side effects across multiple bodily systems, including muscles, tendons, joints, nerves, and mental health. The guidance says systemic fluoroquinolones should be prescribed only when standard alternatives are inappropriate and should not be used for mild, non-bacterial, or self-limiting infections like uncomplicated cystitis or mild bronchitis [3].

For preventing inhaled anthrax, the usual dosage of ciprofloxacin is 500 mg every 12 hours. It is usually continued for 60 days.

Dosage information for children

UseDosageLength of treatment
Treatment of kidney infections and complicated UTIs10 mg/kg to 20 mg/kg (up to 750 mg) every 12 hours10 to 21 days
Treatment of plague15 mg/kg (up to 500 mg) every 8 to 12 hours14 days
Prevention of infections from inhaled anthrax15 mg/kg (up to 500 mg) every 12 hours60 days

For a 55-lb child weighing about 25 kg being treated for a kidney infection, the child's dosage would be 250 mg every 12 hours. For certain infections in children, a doctor may determine the right dosage.

How to take ciprofloxacin

  • Take ciprofloxacin as prescribed by your healthcare professional.
  • Read the medication guide carefully and follow the instructions.
  • Take the tablet at the exact time as advised by your doctor.
  • Swallow the oral tablet whole with a glass of water. Drink plenty of water while taking this medication.

  • Ask your doctor before taking just one-half of the tablet.
  • Take guidance from a healthcare professional before using this medication for your child.

Missed dose

If you miss a dose of ciprofloxacin and it is more than 6 hours until your next dose, take the missed dose as soon as you remember. If it is less than 6 hours away, skip the missed dose and take your next dose at its usual time.

Avoid taking an extra dose to make up for a missed dose, as it can increase the risk of side effects.

Overdose

If you take more than your prescribed dose and experience severe adverse effects, seek emergency medical care.

Who should avoid ciprofloxacin?

Do not take Ciprofloxacin if you are/have:

  • Taking tizanidine (a muscle relaxant), as it can cause a dangerous drop in blood pressure and extreme drowsiness
  • History of myasthenia gravis, as it can worsen muscle weakness and lead to severe breathing difficulties or death
  • History of severe allergic reactions to ciprofloxacin or other fluoroquinolone antibiotics

Tell your doctor before taking ciprofloxacin, as extra caution is needed, if you are/have:

  • History of blockages, aneurysms, or genetic conditions affecting blood vessels
  • Under 18 (it is used in children only for certain infections)
  • Older adults (age 60 and older)
  • Taking corticosteroids, as it sharply increases the risk of tendon rupture
  • Pregnant, planning pregnancy or breastfeeding
  • Kidney or liver disease

Possible interactions

Some medicines may not mix well with Ciprofloxacin. This includes:

  • Theophylline
  • Blood thinners like warfarin
  • Antidiabetic medications like metformin and sulfonylureas
  • Tizanidine
  • QT-prolonging drugs such as amiodarone, sotalol and certain antidepressants
  • Phenytoin
  • Methotrexate

  • Ziprasidone
  • Chlorpromazine
  • Zolpidem

Food, alcohol and drinks while taking ciprofloxacin

Food

Dairy and calcium

Calcium in dairy products can reduce ciprofloxacin absorption. It makes ciprofloxacin less effective, which could lead to an undertreated infection. Avoid dairy products like milk, cheese, and yogurt, as well as calcium-fortified drinks and juices, on their own. Separate these products from ciprofloxacin by at least 2 hours.

Drinks

Caffeine

Ciprofloxacin can make caffeine last longer in your body. It is best to limit caffeinated beverages like coffee, tea and energy drinks.

Alcohol

Alcohol

You can drink alcohol while taking ciprofloxacin, but it may make side effects such as nausea feel worse.

Ciprofloxacin vs other antibiotics

Ciprofloxacin is a fluoroquinolone antibiotic and not a penicillin. Amoxicillin and cephalexin are beta-lactam antibiotics, and azithromycin is a macrolide that works by stopping bacteria from making proteins. These medications are used for the treatment of different bacterial infections, so they are not directly interchangeable.

Frequently asked questions

What is the half-life of ciprofloxacin?

The half-life of ciprofloxacin is about 4 hours. The half-life is the time it takes the body to eliminate half of a drug's dose. It takes about five half-lives for a drug to leave your system entirely.

Is ciprofloxacin a strong antibiotic?

Ciprofloxacin is a potent, broad-spectrum antibiotic belonging to the fluoroquinolone class. It is a high-priority medication used to treat bacterial infections.

How long does ciprofloxacin stay in the body after the last dose?

With normal kidney function and a half-life of about 4 hours, it usually takes about 5.5 half-lives for the drug to be fully cleared, so ciprofloxacin is out of the body in approximately 20-24 hours.

Can you crush Cipro (ciprofloxacin) tablets and mix with food?

Consult a doctor before doing so, as crushing can affect taste and dosing accuracy, especially if mixed with food and not fully consumed. It might reduce the antibiotic's effectiveness.
