1. What is Levalox and what is it used for
The name of this medicine is Levalox. Levalox film-coated tablets contain the active substance levofloxacin, which belongs to a group of medicines called antibiotics. Levofloxacin is a "quinolone" antibiotic. It works by killing the bacteria that cause infections in the body.
Levalox film-coated tablets can be used to treat the following bacterial infections:
- sinusitis,
- lung infections, in patients with long-term breathing problems or pneumonia,
- urinary tract infections, including kidney or bladder infections,
- prostate infections, in cases of chronic infection,
- skin and soft tissue infections, including muscle infections. This is sometimes referred to as "soft tissue" infections.
In some cases, Levalox film-coated tablets may be used to prevent a lung disease called anthrax, which can occur after contact with anthrax bacteria, or to treat this disease.
2. Important information before taking Levalox
When not to take Levalox and contact your doctor:
- If you are allergic to levofloxacin, any other quinolone antibiotic, such as moxifloxacin, ciprofloxacin, or ofloxacin, or any of the other ingredients of this medicine (listed in section 6). Symptoms of an allergic reaction include: rash, difficulty swallowing or breathing, swelling of the lips, face, throat, or tongue.
- If you have ever had epilepsy.
- If you have ever had tendon problems, such as tendonitis, related to treatment with quinolone antibiotics. A tendon is a cord that connects muscles to bones.
- If the medicine has been prescribed for a child or adolescent during growth.
- If you are pregnant, may become pregnant, or suspect that you are pregnant.
- If you are breastfeeding.
You should not take this medicine if any of the above applies to you.
In case of doubt, before starting treatment with Levalox, you should talk to your doctor or pharmacist.
Warnings and precautions
Before starting treatment with Levalox, you should discuss with your doctor or pharmacist if you:
- are 60 years or older,
- are taking corticosteroids, sometimes called steroids (see "Levalox and other medicines"),
- have had a transplant,
- have ever had seizures (epileptic fits),
- have had brain damage caused by a stroke or other brain injury,
- have kidney problems,
- have a condition called "glucose-6-phosphate dehydrogenase deficiency"; you may be more prone to developing serious blood disorders while taking this medicine,
- have had mental health problems in the past,
- have had heart problems: you should be cautious when taking this medicine if you have a prolonged QT interval (visible on an ECG, i.e., an electrical activity test of the heart), you have electrolyte disturbances in the blood (especially low potassium or magnesium levels), you have a slow heart rate (bradycardia), your heart function is impaired (heart failure), you have had a heart attack (myocardial infarction), or you are a woman or an elderly person or are taking other medicines that cause abnormal changes in the ECG (see "Levalox and other medicines"),
- have nerve damage (peripheral neuropathy),
- have an enlarged blood vessel (aortic aneurysm or large peripheral artery aneurysm),
- have had an aortic dissection (tear in the aortic wall),
- have been diagnosed with heart valve problems,
- have a family history of aortic aneurysm or aortic dissection or congenital heart valve problems, or other risk factors or conditions (e.g., connective tissue diseases such as Marfan syndrome, Ehlers-Danlos syndrome, Turner syndrome, or Sjögren's syndrome (an autoimmune inflammatory disease) or vascular diseases such as Takayasu arteritis, giant cell arteritis, Behçet's disease, hypertension, or confirmed atherosclerosis, rheumatoid arthritis (joint disease), or endocarditis),
- suffer from diabetes,
- have had liver problems in the past,
- suffer from myasthenia gravis,
- have had severe skin rash or skin peeling and blistering after taking levofloxacin.
Before taking this medicine
You should not take antibacterial medicines containing fluoroquinolones or quinolones, including Levalox, if you have ever had a severe side effect while taking a quinolone or fluoroquinolone. In such a case, you should inform your doctor as soon as possible.
While taking this medicine
If you experience sudden severe abdominal, back, or chest pain, which may be a sign of an aortic aneurysm or dissection, you should immediately go to the emergency department. The risk of these changes may be higher if you are being treated with systemic corticosteroids.
If you experience sudden shortness of breath, especially when lying down, or notice swelling of the ankles, feet, or abdomen, or an irregular heartbeat (feeling of rapid or irregular heartbeat), you should immediately consult your doctor.
If you experience: sudden, involuntary muscle twitches, muscle tremors, or muscle cramps, you should immediately consult your doctor, as these may be symptoms of myoclonus. Your doctor may decide to discontinue levofloxacin and start appropriate treatment.
If you experience: nausea, general malaise, discomfort, or severe and persistent pain or worsening pain in the abdominal area or vomiting – you should immediately consult your doctor, as these may be symptoms of pancreatitis (acute pancreatitis). See section 2.
If you experience: fatigue, pallor, bruising, uncontrolled bleeding, fever, sore throat, and significant deterioration in health or feeling of reduced resistance to infections – you should immediately consult your doctor, as these may be symptoms of blood disorders. Your doctor should monitor your blood test results. If abnormalities are found in your blood test results, your doctor may decide to discontinue treatment.
Rarely, pain and swelling of the joints and tendons, as well as tendon inflammation or rupture, may occur. The risk is increased in elderly people (over 60 years), after organ transplantation, in cases of kidney problems, or during corticosteroid treatment. Tendon inflammation and rupture can occur within the first 48 hours of treatment and even up to several months after discontinuing Levalox. After the first symptoms of pain or tendon inflammation appear (e.g., in the ankle, wrist, elbow, shoulder, or knee), you should discontinue Levalox, consult your doctor, and rest the affected area. You should avoid excessive strain, as it may increase the risk of tendon rupture.
The patient may rarely experience symptoms of nerve damage (peripheral neuropathy), such as pain, burning, tingling, numbness, and/or weakness, especially in the feet and legs and hands and arms. In such a case, you should discontinue Levalox and immediately inform your doctor to prevent the development of potentially irreversible disease.
Long-term, debilitating, and potentially irreversible severe side effects
Fluoroquinolone and quinolone antibacterial medicines, including Levalox, have been associated with very rare but severe side effects. Some of these have been long-term (lasting for months or years), debilitating, or potentially irreversible. These include: tendon pain, muscle pain, and joint pain in the upper and lower limbs, walking difficulties, abnormal sensations, such as tingling, burning, prickling, numbness, or itching (paresthesia), sensory disturbances, including vision, taste, and smell and hearing disorders, depression, memory disturbances, severe fatigue, and severe sleep disturbances.
If you experience any of these side effects after taking Levalox, you should immediately consult your doctor before continuing treatment. You and your doctor will decide whether to continue treatment, also considering antibiotics from another group.
Severe skin reactions
Severe skin reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported with levofloxacin.
- SJS or TEN may initially appear as red, target-like, or circular patches, often with blisters in the center on the torso. They can also cause mouth ulcers, throat, nose, genital, and eye ulcers (red and swollen eyes). These severe skin rashes are often preceded by fever and flu-like symptoms. These rashes can lead to widespread skin peeling, which can be life-threatening or fatal.
- In DRESS syndrome, flu-like symptoms and a rash on the face appear first, followed by a widespread rash with high body temperature, elevated liver enzymes, and eosinophilia (an increased number of white blood cells) in blood tests, as well as swollen lymph nodes. If you experience a severe rash or any of these skin symptoms, you should discontinue levofloxacin and consult your doctor or seek immediate medical attention.
If you are not sure whether any of the above applies to you, you should talk to your doctor or pharmacist before starting treatment with Levalox.
Children and adolescents
Levalox is contraindicated in children and adolescents.
Levalox and other medicines
You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take. This is because Levalox may affect the action of other medicines. Other medicines may also affect the action of Levalox.
In particular, you should inform your doctor if you are taking any of the following medicines, as the risk of side effects may increase when taking these medicines with Levalox:
- corticosteroids, sometimes called steroids, used in inflammatory conditions; you may be more prone to developing tendonitis or tendon rupture,
- warfarin, used to thin the blood; you may be more prone to bleeding; your doctor may order regular blood tests to check blood clotting,
- theophylline, used in breathing problems; you may be more prone to developing seizures (epileptic fits) if you take Levalox,
- non-steroidal anti-inflammatory medicines (NSAIDs), used in pain and inflammatory conditions, such as acetylsalicylic acid, ibuprofen, fenbufen, ketoprofen, indomethacin; you may be more prone to developing seizures (epileptic fits) if you take Levalox,
- cyclosporine, used after organ transplantation; you may be more prone to developing side effects of cyclosporine,
- medicines that affect heart rhythm; this includes medicines used in irregular heart rhythm (antiarrhythmic medicines, such as quinidine, hydroquinidine, disopyramide, sotalol, dofetilide, ibutilide, and amiodarone), in depression (tricyclic antidepressants, such as amitriptyline and imipramine), in psychiatric disorders (antipsychotic medicines), and in bacterial infections (macrolide antibiotics, such as erythromycin, azithromycin, and clarithromycin),
- probenecid, used in gout; your doctor may recommend taking a lower dose if you have kidney problems,
- cimetidine, used in the treatment of stomach ulcers and heartburn; your doctor may recommend taking a lower dose if you have kidney problems.
You should not take Levalox film-coated tablets at the same time as the following medicines, as they may affect the action of Levalox:
- medicines containing iron (used in anemia), zinc preparations, antacids containing magnesium or aluminum (used in acidity or heartburn), didanosine, or sucralfate (used in stomach ulcers). See section 3 below "If you are already taking medicines containing iron, zinc preparations, antacids, didanosine, or sucralfate".
