Serious warnings and precautions box

Fluoroquinolone antibiotics, like CIPRO ORAL SUSPENSION, are related to disabling and possibly long lasting serious side effects including but not limited to:

  • Tendinitis and tendon rupture: CIPRO ORAL SUSPENSION has caused tendinitis (inflamed tendon) and tendon rupture (partial or complete tear), which may require surgery. If you experience pain, swelling or inflammation around your joints, stop taking CIPRO ORAL SUSPENSION and talk to your healthcare professional. This may happen while you are taking CIPRO ORAL SUSPENSION or for up to several months afterwards. The risk of tendon side effects is higher if you are taking corticosteroids. Tendon problems can happen within the first 48 hours of treatment.
  • Peripheral neuropathy: problems in the nerves that can cause numbness and tingling in your hands and feet, decreased sensation of light touch, pain, temperature, position sense, vibration, and/or motor strength.
  • Neurological and mental health problems: problems in the brain such as seizures, psychosis (loss of touch with reality), confusion and other mental health symptoms. Before you take CIPRO ORAL SUSPENSION, tell your healthcare professional if you have a condition that may increase your chance of having a seizure or if you have a history of seizures or epilepsy. Stop taking CIPRO ORAL SUSPENSION and get immediate medical help if you have any of these symptoms:

    • psychosis, hallucinations, paranoia (see, hear, or believe things that are not real)
    • depression or suicidal thoughts
    • anxiety, agitation, restlessness, or nervousness
    • confusion, disorientation, or disturbances in attention
    • insomnia or nightmares
    • problems with your memory

Fluoroquinolone antibiotics can also cause serious side effects such as:

  • Heart rhythm problems: QT interval prolongation (lengthened heartbeat on an electrocardiogram (ECG) test) and arrhythmia (irregular heartbeat) can happen in patients taking CIPRO ORAL SUSPENSION. In rare cases patients have reported a condition called torsades de pointes, which can cause sudden cardiac death. Talk to your healthcare professional before taking CIPRO ORAL SUSPENSION if you have QT interval prolongation, or any other heart condition that affects your heart rhythm, low levels of potassium in your blood, or are taking any other medications that can affect your heart rhythm.
  • Allergic reactions: CIPRO ORAL SUSPENSION has caused serious allergic reactions that have been fatal. Stop taking CIPRO ORAL SUSPENSION and get immediate medical help if you develop a skin rash or any other symptoms of an allergic reaction.
  • Myasthenia gravis: quinolone antibiotics, including CIPRO ORAL SUSPENSION, can make muscle weakness in people with myasthenia gravis worse. You should not take CIPRO ORAL SUSPENSION if you have myasthenia gravis.
  • Liver problems: CIPRO ORAL SUSPENSION has caused serious liver injury that has resulted in death. Talk to your healthcare professional before taking CIPRO ORAL SUSPENSION if you have liver problems.

See the Serious side effects and what to do about them table, below for information on these and other serious side effects.

What CIPRO ORAL SUSPENSION is used for:

CIPRO ORAL SUSPENSION is an antibiotic used to treat infections caused by bacteria in adults. These include infections of the:

  • respiratory tract
  • urinary tract (bladder, kidneys)
  • prostate
  • skin and soft tissues
  • bone and joint

It is also used in adults to treat the following conditions:

  • carriers of the bacteria Neisseria meningitidis that causes meningitis. It is not used to treat meningitis infections.
  • diarrhea caused by bacterial infections
  • Typhoid fever
  • gonorrhea (an infection caused by the bacteria Neisseria gonorrhea)

Antibacterial drugs like CIPRO ORAL SUSPENSION treat only bacterial infections. They do not treat viral infections such as the common cold. Although you may feel better early in treatment, CIPRO ORAL SUSPENSION should be used exactly as directed. Misuse or overuse of CIPRO ORAL SUSPENSION could lead to the growth of bacteria that will not be killed by CIPRO ORAL SUSPENSION (resistance). This means that CIPRO ORAL SUSPENSION may not work for you in the future. Do not share your medicine.

How CIPRO ORAL SUSPENSION works:

CIPRO ORAL SUSPENSION is an antibiotic that kills the bacteria causing the infection.

The ingredients in CIPRO ORAL SUSPENSION are:

Medicinal ingredient: ciprofloxacin

Non-medicinal ingredients: hypromellose, magnesium stearate, medium chain triglycerides, poly acrylate dispersion, polysorbate 20, polyvidone 25, soy-lecithin, strawberry flavouring, sucrose and water.

CIPRO ORAL SUSPENSION comes in the following dosage form:

Oral suspension: 10 g / 100 mL

Do not use CIPRO ORAL SUSPENSION if:

  • you are allergic to ciprofloxacin, other quinolone antibiotics or any of the non-medicinal ingredients in CIPRO ORAL SUSPENSION (see The ingredients in CIPRO ORAL SUSPENSION are:)
  • you are taking tizanidine, a medication that relaxes muscles
  • you are currently taking agomelatine (currently not marketed in Canada), used to treat depression

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take CIPRO ORAL SUSPENSION. Talk about any health conditions or problems you may have, including if you:

  • have, or have had a family history of, fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase deficiency as CIPRO ORAL SUSPENSION contains sucrose
  • have a history of seizures or epilepsy or are taking medicines that could cause seizures
  • have kidney problems
  • have risk factors for an aortic aneurysm (an abnormal bulge in a large blood vessel called the aorta), or aortic dissection (a tear in the wall of the aorta):

    • have had an aortic aneurysm or aortic dissection
    • have, or if anyone in your family has, a condition called aneurysm disease which is an abnormal bulge in any large blood vessel in the body
    • have any of the following conditions: Marfan syndrome, vascular Ehlers-Danlos syndrome, Takayasu arteritis, giant cell arteritis or Behcet’s disease
    • are 65 years of age or older

Other warnings you should know about:

Aortic aneurysm and aortic dissection: Quinolone antibiotics, including CIPRO ORAL SUSPENSION, have been associated with aneurysms (an enlargement or “bulge” of the aorta or other large blood vessel) and aortic dissection (a tear in the wall of the aorta). Stop taking CIPRO ORAL SUSPENSION and get immediate medical help if you experience sudden, severe pain in your abdomen, chest or back, a pulsating sensation in your abdomen, dizziness or loss of consciousness.

Blood sugar changes: Medicines like CIPRO ORAL SUSPENSION can cause blood sugar levels to rise and drop in patients with diabetes. Serious cases of hypoglycemia (low blood sugar levels) that caused coma or death have been seen with medicines like CIPRO ORAL SUSPENSION. If you have diabetes, check your blood sugar levels often while taking CIPRO ORAL SUSPENSION. Blood sugar changes have also been seen in patients without diabetes.

Sensitivity to light: Sun sensitivity (photosensitivity) can happen when taking CIPRO ORAL SUSPENSION after exposure to sunlight or artificial ultraviolet (UV) light (e.g. tanning beds). You should avoid too much sunlight or artificial UV light while you are taking CIPRO ORAL SUSPENSION. Stop taking CIPRO ORAL SUSPENSION and talk to your healthcare professional if you have sunburn-like skin reactions when exposed to sunlight or UV light.

Clostridium difficile colitis (bowel inflammation): CIPRO ORAL SUSPENSION can cause infections of the colon caused by a bacteria called Clostridium difficile. These infections can vary in severity from mild diarrhea to fatal colitis (inflammation of the colon). If you experience diarrhea or other symptoms of colitis, talk to your healthcare professional. Symptoms of colitis can include stomach pain or cramping, rectal bleeding, urgency or inability to pass stool, fatigue, weight loss and fever.

Driving and using machines: Do not drive or use machinery if you feel dizzy or lightheaded. This is more likely to happen if you drink alcohol while taking CIPRO ORAL SUSPENSION.

Blood tests and monitoring: CIPRO ORAL SUSPENSION can cause abnormal blood test results. Your healthcare professional will decide when to perform blood tests and will interpret the results.

Drug resistance: Using CIPRO ORAL SUSPENSION for too long or not long enough may cause the bacteria to become resistant, and your infection may not be resolved. Your healthcare professional will tell you exactly how long you should be taking CIPRO ORAL SUSPENSION for.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
