1. What Sineflox is and what it is used for

Sineflox contains the active substance called levofloxacin. This medicine belongs to a group of medicines known as antibiotics. Levofloxacin is a "quinolone" antibiotic. This medicine works by killing the bacteria responsible for infections in the body.
Sineflox can be used to treat:

  • acute bacterial infection of the nose and paranasal sinuses (acute bacterial sinusitis)
  • acute infection in a respiratory disease called chronic obstructive bronchopneumopathy, which includes chronic bronchitis
  • community-acquired lung infection (community-acquired pneumonia)
  • complicated urinary tract infections (cystitis, an infection of the bladder, and urethritis, an infection of the urethra, the tube connecting the bladder to the outside) and acute kidney and upper urinary tract infection (pyelonephritis)
  • chronic bacterial infections of the prostate (chronic bacterial prostatitis)
  • bladder infection (uncomplicated cystitis)
  • skin and subcutaneous tissue infections, including muscles. These are sometimes referred to as "soft tissues"
  • prevention and treatment of an infection caused by inhalation of anthrax (a bacterium causing skin, lung, and intestinal disorders)

2. What you should know before taking Sineflox

Before taking this medicine
Do not take antibacterial medicines containing quinolones/fluoroquinolones, including Sineflox,
if you have previously experienced any severe adverse reaction during treatment with a
quinolone or fluoroquinolone. In such a case, inform your doctor as soon as possible.
Do not take this medicine and inform your doctor if:

  • you are allergic (hypersensitive) to levofloxacin, to any other quinolone antibiotic such as moxifloxacin, ciprofloxacin or ofloxacin, or to any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include: skin rash, difficulty swallowing or breathing, swelling of the lips, face, throat or tongue
  • you have had epilepsy
  • you have had tendon-related problems, such as tendinitis, associated with treatment with a "quinolone antibiotic". Tendons are fibrous structures connecting skeletal muscles
  • you are a child or adolescent during the growth period
  • you are pregnant, could become pregnant, or think you may be pregnant
  • you are breastfeeding with breast milk
  • you have been diagnosed with an enlargement or "bulging" of a large blood vessel (aortic aneurysm or peripheral aneurysm of a large blood vessel)
  • you have previously experienced episodes of aortic dissection (a tear in the wall of the aorta)
  • you have a family history of aortic aneurysm, aortic dissection, or other risk factors or predisposing conditions (e.g. connective tissue disorders such as Marfan syndrome, vascular Ehlers-Danlos syndrome, or if you have vascular diseases such as Takayasu arteritis, giant cell arteritis, Behcet’s disease, known high blood pressure, or atherosclerosis).

If you experience sudden pain in the abdomen, chest, or back, go immediately to
the emergency room.
Do not take this medicine if any of the above may in any way apply to you. If you have any
doubts, consult your doctor, nurse, or pharmacist before taking Sineflox.
When taking this medicine
Rarely, joint pain and swelling, and inflammation or rupture
of tendons may occur. The risk is higher if you are elderly (over 60 years of age), if you have received an
organ transplant, if you have kidney problems, or if you are being treated with corticosteroids.
Tendon inflammation and rupture may occur within the first 48 hours of treatment and
up to several months after stopping treatment with Sineflox. At the first signs of pain or
inflammation in a tendon (e.g. in the ankle, wrist, elbow, shoulder, or
knee), stop treatment with Sineflox, consult your doctor, and rest the affected area. Avoid any unnecessary physical activity, as the risk of tendon rupture could
increase.
Warnings and precautions
Consult your doctor or pharmacist before taking this medicine if:

  • you are 60 years old or older
  • you are taking corticosteroids, sometimes called steroids (see “Other medicines and Sineflox”)
  • you have had epileptic seizures
  • you have suffered brain damage due to stroke or other brain injury
  • you have kidney problems
  • you suffer from a condition known as “glucose-6-phosphate dehydrogenase deficiency”. Administration of this medicine increases the likelihood of developing serious blood-related problems
  • you have had mental health issues
  • you have had heart problems: you should exercise caution when using this type of medicine if you were born with or have a family history of QT interval prolongation (seen on electrocardiogram, the heart's electrical tracing), have an electrolyte imbalance in the blood (especially low levels of potassium or magnesium in the blood), have a very slow heart rate (called “bradycardia”), have a weak heart (heart failure), have had a heart attack (myocardial infarction), are female or elderly, or are taking other medicines that can alter the electrocardiogram (see section “Other medicines and Sineflox”).
  • if you have been diagnosed with heart valve insufficiency (aortic and mitral regurgitation);
  • if you have a family history of aortic aneurysm or aortic dissection, congenital heart valve disease, or other risk factors or predisposing conditions (e.g., connective tissue disorders such as Marfan syndrome, Ehlers-Danlos syndrome, Turner syndrome, Sjögren’s syndrome [an autoimmune inflammatory disease], or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behçet’s disease, high blood pressure, known atherosclerosis, rheumatoid arthritis [an autoimmune inflammatory disease], or endocarditis [inflammation of the heart]).
  • you have diabetes
  • you have had liver problems
  • you have myasthenia gravis
  • you have developed a severe skin reaction or skin peeling, blisters and/or mouth ulcers after taking any medicine containing levofloxacin.

If you have any doubts whether any of the above may in any way apply to you, consult your doctor or
pharmacist before taking Sineflox.
While taking Sineflox:

  • if you experience sudden, severe pain in the abdomen, chest, or back, which may be a symptom of aneurysm or aortic dissection, go immediately to the emergency room. The risk may be higher if you are taking systemic corticosteroid medicines.

  • Inform your doctor immediately if you notice a sudden onset of shortness of breath, especially when lying down, or swelling of the ankles, feet, or abdomen, or new episodes of palpitations (sensation of rapid or irregular heartbeat).

  • If you begin to experience sudden involuntary jerks, muscle fasciculations, or contractions

  • consult a doctor immediately, as these may be signs of myoclonus. Your doctor may need to stop treatment with levofloxacin and start appropriate treatment.

  • If you experience fatigue, pale skin, bruising, uncontrolled bleeding, fever, sore throat, and severe worsening of your general condition, or if you feel that your resistance to infections has decreased – consult a doctor immediately, as these may
    be signs of blood disorders. Your doctor should monitor your blood with a complete blood count.
    If blood tests are abnormal, your doctor may need to stop treatment.
    Severe skin reactions
    Serious skin reactions have been reported with the use of levofloxacin, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS).

  • SJS and TEN may initially appear on the body as reddish spots or circular patches, often with central blisters. Mouth, throat, nose, genital, and eye ulcers (red, swollen eyes) may also occur. These serious skin rashes are often preceded by fever and/or flu-like symptoms. The rashes may progress to widespread skin peeling and life-threatening or fatal complications.

  • DRESS initially presents as flu-like symptoms and a skin rash on the face, followed by widespread skin rash with fever, elevated liver enzyme levels in blood tests, increased levels of a type of white blood cell (eosinophilia), and swollen lymph nodes.

If you develop a severe skin rash or any of these other skin symptoms, stop taking levofloxacin and contact your doctor or seek immediate medical help.
Other medicines and Sineflox
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicine. This is because Sineflox can affect the action of other medicines. Some medicines can also affect the action of Sineflox.
In particular, inform your doctor if you are taking any of the following medicines. This
is because taking Sineflox together with other medicines may increase the
likelihood of you experiencing side effects:

  • corticosteroids – sometimes called steroids – used to treat inflammation. The risk of developing tendon inflammation and/or rupture is higher.
  • warfarin – used to delay blood clotting. The risk of bleeding is higher. Your doctor may ask you to have regular blood tests to monitor blood clotting.
  • theophylline – used for respiratory problems. The risk of seizures (epileptic episodes) is higher if you take theophylline together with Sineflox.
  • non-steroidal anti-inflammatory drugs (NSAIDs) – used for pain and inflammation, such as aspirin, ibuprofen, fenbufen, ketoprofen, and indomethacin. The risk of seizures (epileptic episodes) is higher when taken together with Sineflox.
  • cyclosporine – used for organ transplants. The risk of experiencing typical side effects of cyclosporine is higher.
  • medicines known to affect heart rhythm. These include medicines used to treat abnormal heart rhythm (antiarrhythmics such as quinidine, hydroquinidine, disopyramide, amiodarone, sotalol, dofetilide, and ibutilide), depression (tricyclic antidepressants such as amitriptyline and imipramine), psychiatric disorders (antipsychotics), and bacterial infections (macrolide antibiotics such as erythromycin, azithromycin, and clarithromycin).
  • probenecid – used to treat gout. Your doctor may prescribe a lower dose if you have kidney problems.
  • cimetidine – used for ulcers and heartburn. Your doctor may prescribe a lower dose if you have kidney problems. Consult your doctor if any of the above may in any way apply to you.

Do not take Sineflox together with the following medicines. This is because the mechanism
of action of Sineflox may be affected:

  • iron salts in tablets (for anemia), zinc supplements, antacids containing magnesium or aluminium (for acidity or heartburn), didanosine, or sucralfate (for gastric ulcers). See section 3 “If you are taking iron salts in tablets, zinc supplements, antacids, didanosine, or sucralfate”. Rarely, symptoms of nerve damage (neuropathy) such as pain, burning, tingling, numbness, and/or weakness, particularly in the feet and legs or hands and arms, may occur. In such cases, stop treatment with Sineflox and inform your doctor immediately to prevent permanent nerve damage.

Serious, prolonged, disabling, and potentially irreversible side effects

  • Fluoroquinolone/quinolone antibacterial medicines, including Sineflox, have been associated with very rare but serious side effects, some of which are prolonged (lasting months or years), disabling, or may not improve. These include tendon, muscle, and joint pain in arms and legs, difficulty walking, unusual sensations such as tingling, prickling, itching, numbness, or burning (paresthesia), sensory organ disturbances such as changes in vision, taste, smell, or hearing, depression, memory impairment, severe fatigue, and severe sleep disturbances.
  • If you experience any of these side effects after taking Sineflox, consult your doctor immediately before continuing treatment. Your doctor will decide together with you whether to continue treatment and may consider using an antibiotic from another class. Urine tests for opiates In patients taking Sineflox, urine tests may give "false-positive" results for strong painkillers called "opiates". If your doctor considers it necessary to perform urine tests, inform them that you are taking Sineflox. Tuberculosis testing This medicine may cause "false-negative" results in certain laboratory tests used to detect the bacteria causing tuberculosis.

Pregnancy and breastfeeding
Do not take this medicine if:

  • you are pregnant, could become pregnant, or think you may be pregnant
  • you are breastfeeding or think you may breastfeed

Driving and using machines
Some side effects may occur after taking this medicine, including dizziness, drowsiness, subjective sensation of movement (vertigo), or visual disturbances.
Some of these side effects may affect your ability to concentrate and your reaction speed. If this occurs, do not drive or perform activities requiring a high level of attention.
