for Intravenous Infusion

Read this Medication Guide before you start taking ciprofloxacin and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is the most important information I should know about ciprofloxacin?

Ciprofloxacin, a fluoroquinolone antibacterial medicine, can cause serious side effects. Some of these serious side effects can happen at the same time and could result in death.

If you get any of the following serious side effects while you take ciprofloxacin, you should stop taking ciprofloxacin immediately and get medical help right away.

1.

Tendon rupture or swelling of the tendon (tendinitis).
Tendon problems can happen in people of all ages who take ciprofloxacin. Tendons are tough cords of tissue that connect muscles to bones. Symptoms of tendon problems may include:

• pain
• swelling
• tears and swelling of the tendons including the back of the ankle (Achilles), shoulder, hand, thumb, or other tendon sites.

 

• The risk of getting tendon problems while you take ciprofloxacin is higher if you:
  • are over 60 years of age
  • are taking steroids (corticosteroids)
  • have had a kidney, heart or lung transplant.
• Tendon problems can happen in people who do not have the above risk factors when they take ciprofloxacin.
• Other reasons that can increase your risk of tendon problems can include:
  • physical activity or exercise
  • kidney failure
  • tendon problems in the past, such as in people with rheumatoid arthritis (RA).
• Stop taking ciprofloxacin immediately and get medical help right away at the first sign of tendon pain, swelling or inflammation. The most common area of pain and swelling is the Achilles tendon at the back of your ankle. This can also happen with other tendons.
• Tendon rupture can happen while you are taking or after you have finished taking ciprofloxacin. Tendon ruptures can happen within hours or days of taking ciprofloxacin and have happened up to several months after people have finished taking their fluoroquinolone.
• Stop taking ciprofloxacin immediately and get medical help right away if you get any of the following signs or symptoms of a tendon rupture:
  • hear or feel a snap or pop in a tendon area
  • bruising right after an injury in a tendon area
  • unable to move the affected area or bear weight

The tendon problems may be permanent.

2.

Changes in sensation and possible nerve damage (Peripheral Neuropathy). Damage to the nerves in arms, hands, legs, or feet can happen in people who take fluoroquinolones, including ciprofloxacin. Stop taking ciprofloxacin immediately and talk to your healthcare provider right away if you get any of the following symptoms of peripheral neuropathy in your arms, hands, legs, or feet:

pain burning tingling

numbness weakness

Ciprofloxacin may need to be stopped to prevent permanent nerve damage.

3.

Central Nervous System (CNS) effects. Mental health problems and seizures have been reported in people who take fluoroquinolone antibacterial medicines, including ciprofloxacin. Tell your healthcare provider if you have a history of seizures before you start taking ciprofloxacin. CNS side effects may happen as soon as after taking the first dose of ciprofloxacin. Stop taking ciprofloxacin immediately and talk to your healthcare provider right away if you get any of these side effects, or other changes in mood or behavior:

seizures hear voices, see things, or sense things that are not there (hallucinations) feel restless or agitated tremors feel anxious or nervous confusion depression reduced awareness of surroundings

trouble sleeping nightmares feel lightheaded or dizzy feel more suspicious (paranoia) suicidal thoughts or acts headaches that will not go away, with or without blurred vision memory problems false or strange thoughts or beliefs (delusions)

The CNS changes may be permanent.

4.

Worsening of myasthenia gravis (a problem that causes muscle weakness). Fluoroquinolones like ciprofloxacin may cause worsening of myasthenia gravis symptoms, including muscle weakness and breathing problems. Tell your healthcare provider if you have a history of myasthenia gravis before you start taking ciprofloxacin. Call your healthcare provider right away if you have any worsening muscle weakness or breathing problems.

What is ciprofloxacin?

Ciprofloxacin is a fluoroquinolone antibacterial medicine used in adults age 18 years and older to treat certain infections caused by certain germs called bacteria. These bacterial infections include:

• Studies of ciprofloxacin for use in the treatment of plague and anthrax were done in animals only, because plague and anthrax could not be studied in people.
• Ciprofloxacin should not be used in patients with acute exacerbation of chronic bronchitis, acute uncomplicated cystitis, and sinus infections, if there are other treatment options available.
• Ciprofloxacin should not be used as the first choice of antibacterial medicine to treat lower respiratory tract infections caused by a certain type of bacterial called Streptococcus pneumoniae.
• Ciprofloxacin is also used in children younger than 18 years of age to treat complicated urinary tract and kidney infections or who may have breathed in anthrax germs, have plague or have been exposed to plague germs.
• Children younger than 18 years of age have a higher chance of getting bone, joint, or tendon (musculoskeletal) problems such as pain or swelling while taking ciprofloxacin. Ciprofloxacin should not be used as the first choice of antibacterial medicine in children under 18 years of age.

Who should not take ciprofloxacin?

Do not take ciprofloxacin if you:

• have ever had a severe allergic reaction to an antibacterial medicine known as a fluoroquinolone, or are allergic to ciprofloxacin hydrochloride or any of the ingredients in ciprofloxacin. See the end of this Medication Guide for a complete list of ingredients in ciprofloxacin.
• also take a medicine called tizanidine (Zanaflex®).

Ask your healthcare provider if you are not sure.

If you become resistant to ciprofloxacin, ciprofloxacin and other antibacterial medicines may not work for you in the future.

• If you take too much ciprofloxacin, call your healthcare provider or get medical help right away.

What should I avoid while taking ciprofloxacin?

• Ciprofloxacin can make you feel dizzy and lightheaded. Do not drive, operate machinery, or do other activities that require mental alertness or coordination until you know how ciprofloxacin affects you.
• Avoid sunlamps, tanning beds, and try to limit your time in the sun. Ciprofloxacin can make your skin sensitive to the sun (photosensitivity) and the light from sunlamps and tanning beds. You could get a severe sunburn, blisters or swelling of your skin. If you get any of these symptoms while you take ciprofloxacin, call your healthcare provider right away. You should use a sunscreen and wear a hat and clothes that cover your skin if you have to be in sunlight.

What are the possible side effects of ciprofloxacin?

Ciprofloxacin may cause serious side effects, including:

• Serious allergic reactions. Serious allergic reactions, including death, can happen in people taking fluoroquinolones, including ciprofloxacin, even after only 1 dose. Stop taking ciprofloxacin and get emergency medical help right away if you get any of the following symptoms of a severe allergic reaction:

  hives trouble breathing or swallowing swelling of the lips, tongue, face throat tightness, hoarseness

  rapid heartbeat faint skin rash

  Skin rash may happen in people taking ciprofloxacin even after only 1 dose. Stop taking ciprofloxacin at the first sign of a skin rash and call your healthcare provider. Skin rash may be a sign of a more serious reaction to ciprofloxacin.

• Liver damage (hepatotoxicity). Hepatotoxicity can happen in people who take ciprofloxacin. Call your healthcare provider right away if you have unexplained symptoms such as:

  nausea or vomiting stomach pain fever weakness abdominal pain or tenderness itching

  unusual tiredness loss of appetite light colored bowel movements dark colored urine yellowing of the skin and whites of your eyes

  Stop taking ciprofloxacin and tell your healthcare provider right away if you have yellowing of your skin or white part of your eyes, or if you have dark urine. These can be signs of a serious reaction to ciprofloxacin (a liver problem).

The chances of this event are higher in people:
  • who are elderly.
  • with a family history of prolonged QT interval.
  • with low blood potassium (hypokalemia) or low magnesium (hypomagnesemia).
  • who take certain medicines to control heart rhythm (antiarrhythmics).
