AUDIENCE: Health Professional, Infectious Disease, Cardiology, Patient
ISSUE: FDA review found that fluoroquinolone antibiotics can increase the occurrence of rare but serious events of ruptures or tears in the main artery of the body, called the aorta. These tears, called aortic dissections, or ruptures of an aortic aneurysm can lead to dangerous bleeding or even death. They can occur with fluoroquinolones for systemic use given by mouth or through an injection.
BACKGROUND: Fluoroquinolone antibiotics are approved to treat certain bacterial infections and have been used for more than 30 years. They work by killing or stopping the growth of bacteria that can cause illness. Without treatment, some infections can spread and lead to serious health problems (see List of Currently Available FDA-Approved Systemic Fluoroquinolones, available at http://bit.ly/2LN7Omq).
Healthcare professionals should:
- Avoid prescribing fluoroquinolone antibiotics to patients who have an aortic aneurysm or are at risk for an aortic aneurysm, such as patients with peripheral atherosclerotic vascular diseases, hypertension, certain genetic conditions such as Marfan syndrome and Ehlers-Danlos syndrome, and elderly patients.
- Prescribe fluoroquinolones to these patients only when no other treatment options are available.
- Advise all patients to seek immediate medical treatment for any symptoms associated with aortic aneurysm.
- Stop fluoroquinolone treatment immediately if a patient reports side effects suggestive of aortic aneurysm or dissection.
- Seek medical attention immediately by going to an emergency room or calling 911 if you experience sudden, severe, and constant pain in the stomach, chest or back.
- Be aware that symptoms of an aortic aneurysm often do not show up until the aneurysm becomes large or bursts, so report any unusual side effects from taking fluoroquinolones to your health care professional immediately.
- Inform your health professional before starting an antibiotic prescription, if you have a history of aneurysms, blockages or hardening of the arteries, high blood pressure, or genetic conditions such as Marfan syndrome or Ehlers-Danlos syndrome.
- Not stop the antibiotic without first talking to your health care professional.
Using ciprofloxacin injection increases the risk that you will develop tendinitis (swelling of a fibrous tissue that connects a bone to a muscle) or have a tendon rupture (tearing of a fibrous tissue that connects a bone to a muscle) during your treatment or for up to several months afterward. These problems may affect tendons in your shoulder, your hand, the back of your ankle, or in other parts of your body. Tendinitis or tendon rupture may happen to people of any age, but the risk is highest in people over 60 years of age. Tell your doctor if you have or have ever had a kidney, heart, or lung transplant; kidney disease; a joint or tendon disorder such as rheumatoid arthritis (a condition in which the body attacks its own joints, causing pain, swelling, and loss of function); or if you participate in regular physical activity. Tell your doctor and pharmacist if you are taking oral or injectable steroids such as dexamethasone, methylprednisolone (Medrol), or prednisone (Rayos). If you experience any of the following symptoms of tendinitis, stop using ciprofloxacin injection, rest, and call your doctor immediately: pain, swelling, tenderness, stiffness, or difficulty in moving a muscle. If you experience any of the following symptoms of tendon rupture, stop using ciprofloxacin injection and get emergency medical treatment: hearing or feeling a snap or pop in a tendon area, bruising after an injury to a tendon area, or inability to move or bear weight on an affected area.
Using ciprofloxacin injection may cause changes in sensation and nerve damage that may not go away even after you stop using ciprofloxacin. This damage may occur soon after you begin using ciprofloxacin injection. Tell your doctor if you have ever had peripheral neuropathy (a type of nerve damage that causes tingling, numbness, and pain in the hands and feet). If you experience any of the following symptoms, stop using ciprofloxacin and call your doctor immediately: numbness, tingling, pain, burning, or weakness in the arms or legs; or a change in your ability to feel light touch, vibrations, pain, heat, or cold.
Using ciprofloxacin injection may affect your brain or nervous system and cause serious side effects. This can occur after the first dose of ciprofloxacin injection. Tell your doctor if you have or have ever had seizures, epilepsy, cerebral arteriosclerosis (narrowing of blood vessels in or near the brain that can lead to stroke or ministroke), stroke, changed brain structure, or kidney disease. If you experience any of the following symptoms, stop using ciprofloxacin injection and call your doctor immediately: seizures; tremors; dizziness; lightheadedness; headaches that won't go away (with or without blurred vision); difficulty falling asleep or staying asleep; nightmares; not trusting others or feeling that others want to hurt you; hallucinations (seeing things or hearing voices that do not exist); thoughts or actions towards hurting or killing yourself; feeling restless, anxious, nervous, depressed, memory problems, or confused, or other changes in your mood or behavior.
Using ciprofloxacin injection may worsen muscle weakness in people with myasthenia gravis (a disorder of the nervous system that causes muscle weakness) and cause severe difficulty breathing or death. Tell your doctor if you have myasthenia gravis. Your doctor may tell you not to use ciprofloxacin injection. If you have myasthenia gravis and your doctor tells you that you should use ciprofloxacin injection, call your doctor immediately if you experience muscle weakness or difficulty breathing during your treatment.
Talk to your doctor about the risks of using ciprofloxacin injection.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ciprofloxacin injection. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs) or the manufacturer's website to obtain the Medication Guide.
Why is this medication prescribed?
Ciprofloxacin injection is used to treat certain infections caused by bacteria such as pneumonia; and infections of the skin, bone, joint, abdomen (stomach area), urinary tract, and prostate (male reproductive gland). Ciprofloxacin injection is also used to treat patients who have fever and are at high risk for infection because they have very few white blood cells. Ciprofloxacin injection is also used to prevent or treat plague (a serious infection that may be spread on purpose as part of a bioterror attack) and inhalation anthrax (a serious infection that may be spread by anthrax germs in the air on purpose as part of a bioterror attack). Ciprofloxacin may also be used to treat bronchitis and sinus infections, but should not be used for these conditions if there are other treatment options available. Ciprofloxacin injection is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections.
Antibiotics such as ciprofloxacin injection will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
How should this medicine be used?
Ciprofloxacin injection comes as a solution (liquid) to be given through a needle or catheter placed in your vein. It is usually infused (injected slowly) intravenously (into a vein) over a period of 60 minutes, usually once every 8 or 12 hours. The length of your treatment depends on the type of infection you have. Your doctor will tell you how long to use ciprofloxacin injection.
You may receive ciprofloxacin injection in a hospital or you may use the medication at home. If you will be using ciprofloxacin injection at home, your healthcare provider will show you how to infuse the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions. Ask your healthcare provider what to do if you have any problems infusing ciprofloxacin injection.
You should begin feeling better during the first few days of your treatment with ciprofloxacin injection. If your symptoms do not improve, or if they get worse, call your doctor.
Use ciprofloxacin injection until you finish the prescription, even if you feel better. Do not stop using ciprofloxacin injection without talking to your doctor unless you experience certain serious side effects listed in the IMPORTANT WARNING or SIDE EFFECTS sections. If you stop using ciprofloxacin injection too soon or if you skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.
Other uses for this medicine
In the event of biological warfare, ciprofloxacin may be used to treat and prevent dangerous illnesses that are deliberately spread such as , tularemia, and anthrax of the skin or mouth. Ciprofloxacin injection is also sometimes used to treat cat scratch disease (an infection that may develop after a person is bitten or scratched by a cat), Legionnaires' disease (type of lung infection), and infections of the outer ear that spread to the bones of the face. Ciprofloxacin injection is also sometimes used to prevent infections in people who are having certain types of surgery.Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
