1. What is Bactyflox and what is it used for

The name of this medication is Bactyflox. Bactyflox contains an active ingredient called levofloxacin, which belongs to a group of medications called antibiotics. Levofloxacin is a type of antibiotic known as a quinolone, and it works by killing the bacteria that cause infections in your body.

Bactyfloxcanbeusedtotreatinfectionsin:

• the nasal sinuses.
• the lungs, in people with long-term respiratory problems or pneumonia.
• the urinary tract, including the kidneys or bladder.
• the prostate, when the infection is persistent.
• the skin and underlying tissues, including muscles. This is sometimes referred to as "soft tissue".

In some special situations, Bactyflox can be used to reduce the likelihood of acquiring a lung infection called anthrax or worsening of the disease after exposure to the anthrax-causing bacteria.

2. What you need to know before taking Bactyflox

Do not take this medicationand consult your doctor if:

• You are allergic to levofloxacin, other quinolone-type antibiotics such as moxifloxacin, ciprofloxacin, or ofloxacin, or any of the other components of this medication (listed in section 6).
• The signs of an allergic reaction include: skin rash, difficulty swallowing or breathing, swelling of the lips, face, throat, or tongue.
• You have or have had epilepsy.
• You have ever had tendon problems, such as tendinitis, related to taking quinolone-type medications. The tendon is the tissue that connects your muscle to your skeleton.
• You are a child or adolescent in the growth phase.
• You are pregnant, may become pregnant, or think you may be pregnant.
• You are breastfeeding.

Do not take this medication if any of the above cases apply to you. If in doubt, consult your doctor or pharmacist before taking Bactyflox.

Warnings and precautions

Consult your doctor or pharmacist before taking your medication if:

• You are 60 years old or older.
• You are using corticosteroids, sometimes called steroids (see section "Taking Bactyflox with other medications").
• You have received a transplant.
• You have had a seizure (convulsions) in the past.
• You have had brain damage due to a stroke or other brain injury.
• You have kidney problems.
• You have what is known as "glucose-6-phosphate dehydrogenase deficiency", as you may be prone to having serious blood problems when taking this medication.
• You have had mental health problems in the past.
• You have had heart problems: caution should be exercised when using this type of medication if you were born with, or have a family history of, prolonged QT interval (seen on an electrocardiogram (ECG), a graphical representation of the heart's electrical activity), have an imbalance in blood salt levels (especially low potassium or magnesium levels in the blood), have a slow heart rate (bradycardia), have a weak heart (heart failure), have a history of heart attack (myocardial infarction), if you are a woman or an elderly person, or are taking other medications that may cause abnormal changes in the ECG (see section "Taking Bactyflox with other medications").
• You are diabetic.
• You have had liver problems in the past.
• You have myasthenia gravis.
• You have peripheral nerve disorder (peripheral neuropathy).
• You have been diagnosed with an aneurysm (a bulge in a large blood vessel) or a large peripheral blood vessel aneurysm.
• You have had a previous episode of aortic dissection (tear in the aortic wall).
• You have been diagnosed with heart valve insufficiency (regurgitation of the heart valves).
• If you have a family history of aortic aneurysm or aortic dissection, congenital heart valve disease, or other risk factors or predisposing disorders (e.g., connective tissue disorders such as Marfan syndrome or Ehlers-Danlos vascular syndrome, Turner syndrome, or Sjögren's syndrome (an autoimmune inflammatory disease), or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behçet's disease, high blood pressure, or atherosclerosis, or rheumatoid arthritis (a joint disease), or endocarditis (a heart infection)).
• You have developed a severe skin rash or skin peeling, blisters, and/or ulcers in the mouth after taking levofloxacin.

Severe skin reactions

Severe skin reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported with the use of levofloxacin.

• SJS/TEN may initially appear on the trunk as reddish target-like lesions or circular patches, often with blisters in the center. They can also appear as ulcers in the mouth, throat, nose, genitals, and eyes (red and swollen eyes). These severe skin rashes are often preceded by fever and/or flu-like symptoms. The rashes can progress to widespread skin peeling and life-threatening or fatal complications.

• DRESS is initially manifested by flu-like symptoms and a rash on the face, followed by a more widespread rash with elevated body temperature, elevated liver enzymes observed in blood tests, and an increase in a type of white blood cell (eosinophilia) and enlarged lymph nodes.

If you develop a severe rash or any of these skin symptoms, stop taking levofloxacin and contact your doctor or seek immediate medical attention.

Do not take antibacterial medications containing fluoroquinolones or quinolones, including Levofloxacino, if you have experienced a severe adverse reaction in the past when taking a quinolone or fluoroquinolone. If this is the case, inform your doctor as soon as possible.

While taking your medication:

• If you experience sudden and severe pain in the abdomen, chest, or back, which can be symptoms of aortic dissection or aneurysm, go to the emergency room immediately. The risk may increase if you are receiving systemic corticosteroid treatment.

• If you start experiencing sudden shortness of breath, especially when lying down, or if you notice swelling in the ankles, feet, or abdomen, or the appearance of heart palpitations (feeling of rapid or irregular heartbeat), inform your doctor immediately.

• If you start experiencing sudden, involuntary jerks, muscle spasms, or contractions - consult a doctor immediately, as these could be signs of myoclonus. Your doctor may need to interrupt treatment with levofloxacin and initiate appropriate treatment.

• If you experience fatigue, pale skin, bruising, uncontrolled bleeding, fever, sore throat, and a severe deterioration of your general condition, or a feeling that your resistance to infections may be decreased - consult a doctor immediately, as these could be signs of blood disorders. Your doctor should monitor your blood with blood counts. In case of abnormal blood counts, your doctor may need to interrupt treatment.

In rare cases, pain and swelling in the joints and inflammation or rupture of the tendons can occur. The risk is higher if you are an elderly person (over 60 years old), have received an organ transplant, have kidney problems, or are being treated with corticosteroids. Tendon inflammation and rupture can occur within the first 48 hours of treatment and even several months after stopping treatment with Bactyflox. At the first sign of pain or tendon inflammation (e.g., in the ankle, wrist, elbow, shoulder, or knee), stop taking Bactyflox, contact your doctor, and rest the affected area. Avoid any unnecessary exercise, as it may increase the risk of tendon rupture.

In rare cases, you may experience symptoms of nerve damage (peripheral neuropathy) such as pain, burning, tingling, numbness, and/or weakness, especially in the feet and legs or hands and arms. If this happens, stop taking Bactyflox and inform your doctor immediately to prevent the development of a potentially irreversible disorder.

Severe, disabling, long-lasting, and potentially irreversible side effects

Antibacterial medications containing fluoroquinolones or quinolones, including Bactyflox, have been associated with very rare but severe side effects, some of which were long-lasting (persisting for months or years), disabling, or potentially irreversible. These include pain in the tendons, muscles, and joints of the upper and lower limbs, difficulty walking, abnormal sensations such as pins and needles, tingling, numbness, or burning, sensory disorders such as decreased vision, taste, smell, or hearing, depression, decreased memory, intense fatigue, and severe sleep disorders.

If you experience any of these side effects after taking Bactyflox, contact your doctor immediately, before continuing treatment. You and your doctor will decide whether to continue or not continue treatment, also considering the use of an antibiotic from another class.

Inform your doctor or pharmacist before taking Bactyflox if you are unsure whether any of the above cases apply to you.

Taking Bactyflox with other medications

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication. This is because Bactyflox can affect the functioning of other medications. Additionally, some medications can affect the functioning of Bactyflox.

In particular, inform your doctor if you are taking any of the following medications, as they increase the likelihood of experiencing side effects when taken with Bactyflox:

• Corticosteroids, sometimes called steroids - used for inflammation. You may be more likely to experience tendon inflammation and/or rupture.
• Warfarin - used to make blood more fluid. You may be more likely to experience bleeding. Your doctor may need to perform periodic blood tests to check if your blood is clotting correctly.
• Theophylline - used for respiratory problems. You may be more likely to experience a seizure (convulsions) if taken with Bactyflox.
• Non-steroidal anti-inflammatory drugs (NSAIDs) - used for pain and inflammation, such as acetylsalicylic acid, ibuprofen, fenbufen, ketoprofen, indomethacin. You may be more likely to experience a seizure (convulsions) when taken with Bactyflox.
• Cyclosporine - used after organ transplants. You may be more likely to experience the side effects of cyclosporine.
• Medications with a known effect on heartbeats. This includes medications used for abnormal heart rhythm (antiarrhythmics such as quinidine, hydroquinidine, disopyramide, sotalol, dofetilide, ibutilide, and amiodarone), for depression (tricyclic antidepressants such as amitriptyline and imipramine), for psychiatric disorders (antipsychotics), and for bacterial infections (macrolide antibiotics such as erythromycin, azithromycin, and clarithromycin).
• Probenecid (used for gout). If you have kidney problems, your doctor may want to give you a lower dose.
• Cimetidine (used for ulcers and heartburn). If you have kidney problems, your doctor may want to give you a lower dose.

Inform your doctor if any of the above cases apply to you.

Do not take Bactyflox at the same time as the following medications, as they may affect the action of Bactyflox:

• Iron tablets (for anemia), zinc supplements, antacids containing aluminum or magnesium (for acidity or heartburn), didanosine, or sucralfate (for stomach ulcers). See section 3 "If you are already taking iron, zinc supplements, antacids, didanosine, or sucralfate" below.

Determination of opiates in urine

Urine tests may show "false positive" results for the presence of strong painkillers called "opiates" in patients taking Bactyflox. Inform your doctor that you are taking Bactyflox if you have been prescribed a urine test.

Tuberculosis test

This medication may cause a "false negative" result in some laboratory tests that look for the bacteria that cause tuberculosis.

Pregnancy and breastfeeding

Do not take this medication if:

• you are pregnant, may become pregnant, or think you may be pregnant.
• you are breastfeeding or plan to breastfeed.

Driving and using machines

Some side effects, such as dizziness, drowsiness, balance disturbance (vertigo), or visual disturbances, may occur. Some of these side effects can affect your ability to concentrate or reduce your reaction time. If this happens, do not drive or perform any work that requires a high level of attention.

3. How to take Bactyflox
