2. What you need to know before you take Tavanic tablets

Do not take this medicine and consult your doctor if:

• You are allergic to levofloxacin, to other quinolone antibiotics 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

Warnings and precautions

Consult your doctor or pharmacist before starting to take your medicine if:

• You are 60 years old or older.
• You are using corticosteroids, sometimes called steroids (see section "Other medicines and Tavanic").
• 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 medicine.
• You have had mental health problems in the past.
• You have had heart problems: caution should be exercised when using this type of medicine if you were born with, or have a family history of, prolongation of the QT interval (seen on an electrocardiogram (ECG), a graphical representation of the electrical activity of the heart), 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 medicines that may cause abnormal changes in the ECG (see section "Other medicines and Tavanic").
• You are diabetic.
• You have had liver problems in the past.
• You have myasthenia gravis.
• You have peripheral nerve disorder (peripheral neuropathy).
• If you have been diagnosed with an aneurysm or a large blood vessel "bulge" (aortic aneurysm or large peripheral blood vessel aneurysm).
• If you have had a previous episode of aortic dissection (tear in the aortic wall).
• If you have been diagnosed with heart valve insufficiency (regurgitation of the heart valves).
• If you have a family history of aortic dissection or aneurysm, 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, or Sjögren's syndrome (an autoimmune inflammatory disease), or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behçet's disease, hypertension, atherosclerosis, rheumatoid arthritis (a joint disease), or endocarditis (a heart infection).
• If you have ever developed a severe skin rash or peeling of the skin, blisters, and/or sores in the mouth after taking levofloxacin.

Severe skin reactions

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

• SJS/TEN may initially appear on the trunk as reddish targets 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 in the blood (eosinophilia) and enlarged lymph nodes.
• Widespread skin rash, red and scaly, with bumps under the skin (including skin folds, chest, abdomen (including stomach), back, and arms) and blisters, accompanied by fever. Symptoms usually appear at the start of treatment (acute generalized exanthematous pustulosis).

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

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

While taking your medicine:

• If you feel a sudden and severe pain in your 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 onset of shortness of breath, especially when lying down, or if you notice swelling in your 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 and involuntary jerks, muscle spasms, or muscle 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 have nausea, general discomfort, have intense discomfort or ongoing pain in the stomach area, or vomit - consult a doctor immediately, as this could be a sign of pancreatitis (inflammation of the pancreas).
• If you experience fatigue, pale skin, bruising, uncontrolled bleeding, fever, sore throat, and a severe deterioration in 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.

Rarely, pain and swelling in the joints and inflammation or rupture of the tendons can occur. The risk is greater 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 Tavanic. At the first sign of pain or tendon inflammation (e.g., in the ankle, wrist, elbow, shoulder, or knee), stop taking Tavanic, contact your doctor, and rest the affected area. Avoid any unnecessary exercise, as this could increase the risk of tendon rupture.

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

Severe, long-lasting, and potentially irreversible adverse effects

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

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

Inform your doctor or pharmacist before taking Tavanic if you are not sure if any of the above cases apply to you.

Other medicines and Tavanic

Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is because Tavanic can affect the way other medicines work. Also, some medicines can affect the way Tavanic works.

In particular, inform your doctor if you are taking any of the following medicines, as they may increase the risk of adverse effects when taken with Tavanic:

• Corticosteroids, sometimes called steroids - used for inflammation. You may be more likely to experience tendon inflammation and/or rupture.
• Warfarin - used to make the 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 Tavanic.
• 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 Tavanic.
• Cyclosporine - used after organ transplants. You may be more likely to experience the adverse effects of cyclosporine.
• Medicines that affect your heart rhythm. This includes medicines 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. Your doctor may need to give you a lower dose if you have kidney problems.
• Cimetidine - used for ulcers and heartburn. Your doctor may need to give you a lower dose if you have kidney problems.

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

Do not take Tavanic tablets at the same time as the following medicines, as they may affect the way Tavanic tablets work:

• Iron tablets (for anemia), zinc supplements, antacids that contain aluminum or magnesium (for acidity or heartburn), didanosine, or sucralfate (for stomach ulcers). See section 3 "If you are already taking iron tablets, 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 Tavanic. Inform your doctor that you are taking Tavanic if you have been asked for a urine test.

Tuberculosis test

This medicine 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 medicine if:

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

Driving and using machines

Some adverse effects such as dizziness, drowsiness, altered balance (vertigo), or visual disturbances may occur. Some of these adverse 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.

Tavanic contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; it is essentially "sodium-free".
