(sip roe flox' a sin)
AUDIENCE: Internal Medicine, Family Practice, Pharmacy, Patient
ISSUE: FDA is advising that the serious side effects associated with fluoroquinolone antibacterial drugs generally outweigh the benefits for patients with sinusitis, bronchitis, and uncomplicated urinary tract infections who have other treatment options. For patients with these conditions, fluoroquinolones should be reserved for those who do not have alternative treatment options.
An FDA safety review has shown that fluoroquinolones when used systemically (i.e. tablets, capsules, and injectable) are associated with disabling and potentially permanent serious side effects that can occur together. These side effects can involve the tendons, muscles, joints, nerves, and central nervous system.
As a result, FDA is requiring the drug labels and Medication Guides for all fluoroquinolone antibacterial drugs to be updated to reflect this new safety information. FDA is continuing to investigate safety issues with fluoroquinolones and will update the public with additional information if it becomes available.
See the FDA Drug Safety Communication (see http://1.usa.gov/1TdvrCk ) for a list of currently available FDA approved fluoroquinolones for systemic use.
BACKGROUND: The safety issues described in the Drug Safety Communication were also discussed at an FDA Advisory Committee (see http://1.usa.gov/1TaaUBN ) meeting in November 2015.
RECOMMENDATION: Patients should contact your health care professional immediately if you experience any serious side effects while taking your fluoroquinolone medicine. Some signs and symptoms of serious side effects include tendon, joint and muscle pain, a "pins and needles" tingling or pricking sensation, confusion, and hallucinations. Patients should talk with your health care professional if you have any questions or concerns.
Health care professionals should stop systemic fluoroquinolone treatment immediately if a patient reports serious side effects, and switch to a non-fluoroquinolone antibacterial drug to complete the patient's treatment course.

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 (Decadron, Dexpak), methylprednisolone (Medrol), or prednisone (Sterapred). 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 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 medicine prescribed?
Ciprofloxacin injection is used to treat certain infections caused by bacteria. Ciprofloxacin injection is also used to prevent or treat anthrax (a serious infection that may be spread on purpose as part of a bioterror attack) in people who may have been exposed to anthrax germs in the air. Ciprofloxacin injection is in a class of antibiotics called fluoroquinolones. It works by killing bacteria that cause infections. Antibiotics will not work for colds, flu, or other viral infections.
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 are using ciprofloxacin injection at home, use it at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or other health care provider to explain any part you do not understand. Use ciprofloxacin injection exactly as directed. Do not infuse it more quickly than directed. Do not use more or less of it or use it more often than prescribed by your doctor.
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.
Are there 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 plague, tularemia, and anthrax of the skin or mouth. 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.
