6. Contents of the pack and other information
Avelox contains the active substance moxifloxacin, which belongs to a group of antibiotics called fluoroquinolones. Avelox works by killing bacteria that cause infections if they are caused by bacteria that are susceptible to moxifloxacin.
Avelox is used in adults for treating the following bacterial infections:
- Infection of the lungs (pneumonia) acquired outside the hospital
- Infections of the skin and soft tissue
Contact your doctor if you are not sure if you belong to a patient group described below.
- If you are allergic to the active substance moxifloxacin, any other quinolone antibiotics or any of the other ingredients of this medicine (listed in section 6).
- If you are pregnant or breast-feeding.
- If you are under 18 years of age.
- If you have a history of tendon disease or disorder which was related to treatment with quinolone antibiotics (see sections Warnings and precautions and 4. Possible side effects).
- If you were born with or have had any condition with abnormal heart rhythm (seen on ECG, electrical recording of the heart).
- If you have salt imbalance in the blood (especially low levels of potassium or magnesium in the blood).
- If you have a very slow heart rhythm (called ‘bradycardia’).
- If you have a weak heart (heart failure).
- If you have a history of abnormal heart rhythms.
- If you are taking other medicines that result in abnormal ECG changes (see section Other medicines and Avelox). This is because Avelox can cause changes on the ECG, that is a prolongation of the QT-interval i.e. delayed conduction of electrical signals.
- If you have a severe liver disease or liver enzymes (transaminases) that are higher than 5 times the upper normal limit.
Before taking this medicine
You should not take fluoroquinolone/quinolone antibacterial medicines, including Avelox, if you have experienced any serious adverse reaction in the past when taking a quinolone or fluoroquinolone. In this situation, you should inform your doctor as soon as possible.
Talk to your doctor before Avelox is administered for the first time
- Avelox can change your heart’s ECG, especially if you are female, or if you are elderly. If you are currently taking any medicine that decreases your blood potassium levels, consult your doctor before Avelox is administered (see also sections Do not use Avelox and Other medicines and Avelox).
- If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking moxifloxacin.
- If you suffer from epilepsy or a condition which makes you likely to have convulsions, tell your doctor before Avelox is administered.
- If you have or have ever had any mental health problems, consult your doctor before Avelox is administered.
- If you suffer from myasthenia gravis using Avelox may worsen the symptoms of your disease. If you think you are affected consult your doctor immediately.
- If you have been diagnosed with an enlargement or “bulge” of a large blood vessel (aortic aneurysm or large vessel peripheral aneurysm).
- If you have experienced a previous episode of aortic dissection (a tear in the aorta wall).
- If you have been diagnosed with leaking heart valves (heart valve regurgitation).
- If you have a family history of aortic aneurysm or aortic dissection or congenital heart valve disease, or other risk factors or predisposing conditions (e.g. connective tissue disorders such as Marfan syndrome or Ehlers-Danlos syndrome, Turner syndrome, Sjögren´s syndrome [an inflammatory autoimmune disease], or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behçet´s disease, high blood pressure, or known atherosclerosis, rheumatoid arthritis [a disease of the joints] or endocarditis [an infection of the heart]).
- If you are diabetic because you may experience a risk of change in blood sugar levels with moxifloxacin.
- If you or any member of your family have glucose-6-phosphate dehydrogenase deficiency (a rare hereditary disease), inform your doctor, who will advise whether Avelox is suitable for you.
- Avelox should be given intravenously (in the vein) only, and should not be administered into an artery.
- If you experience palpitations or irregular heart beat during the period of treatment, you should inform your doctor immediately. He/she may wish to perform an ECG to measure your heart rhythm.
- The risk of heart problems may increase with increase of the dose and the speed of
the perfusion into your vein.
- There is a rare chance that you may experience a severe, sudden allergic reaction (an anaphylactic reaction/shock) even with the first dose, with symptoms that may include tightness in the chest, feeling dizzy, feeling sick or faint, or experience dizziness on standing. If this happens, treatment with Avelox solution for infusion has to be discontinued immediately.
- Avelox may cause a rapid and severe inflammation of the liver which could lead to life-threatening liver failure (including fatal cases, see section 4. Possible side effects). Please contact your doctor before you continue the treatment if you suddenly start to feel unwell or notice yellowing of the whites of the eyes, dark urine, itching of the skin, a tendency to bleed or disturbances of thought or wakefulness.
- Serious skin reactions
Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, and acute generalised exanthematous pustulosis (AGEP) have been reported with the use of moxifloxacin.
If you develop a serious rash or another of these skin symptoms, stop taking moxifloxacin and contact your doctor or seek medical attention immediately.
- SJS/TEN can appear initially as reddish target-like spots or circular patches often with central blisters on the trunk. Also, ulcers of mouth, throat, nose, genitals and eyes (red and swollen eyes) can occur. These serious skin rashes are often preceded by fever and/or flu-like symptoms. The rashes may progress to widespread peeling of the skin and life-threatening complications or be fatal.
- AGEP appears at the initiation of treatment as a red, scaly widespread rash with bumps under the skin and blisters accompanied by fever. The most common location: mainly localized on the skin folds, trunk, and upper extremities.
- Quinolone antibiotics, including Avelox, may cause convulsions. If this happens, treatment with Avelox has to be discontinued.
- Prolonged, disabling and potentially irreversible serious side effects.
Fluoroquinolone/quinolone antibacterial medicines, including Avelox, have been associated with very rare but serious side effects, some of them being long lasting (continuing months or years), disabling or potentially irreversible. This includes tendon, muscle and joint pain of the upper and lower limbs, difficulty in walking, abnormal sensations such as pins and needles, tingling, tickling, numbness or burning (paraesthesia), sensory disorders including impairment of vision, taste and smell, and hearing, depression, memory impairment, severe fatigue, and severe sleep disorders. If you experience any of these side effects after taking Avelox, contact your doctor immediately prior to continuing treatment. You and your doctor will decide on continuing the treatment considering also an antibiotic from another class.
- You may rarely experience symptoms of nerve damage (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 Avelox and inform your doctor immediately in order to prevent the development of potentially irreversible condition.
- You may experience mental health problems even when taking quinolone antibiotics, including Avelox, for the first time. In very rare cases depression or mental health problems have led to suicidal thoughts and self-injurious behaviour such as suicide attempts (see section 4. Possible side effects). If you develop such reactions, treatment with Avelox has to be discontinued.
- You may develop diarrhoea whilst taking, or after taking, antibiotics including Avelox. If this becomes severe or persistent or you notice that your stool contains blood or mucus you should stop using Avelox immediately and consult your doctor. In this situation, you should not take medicines that stop or slow down bowel movement.
- Pain and swelling in the joints and inflammation or rupture of tendons may occur rarely (see sections Do not use Avelox and 4. Possible side effects). Your risk is increased if you are elderly (above 60 years of age), have received an organ transplant, have kidney problems or if you are being treated with corticosteroids. Inflammation and ruptures of tendons may occur within the first 48 hours of treatment and even up to several months after stopping of Avelox therapy. At the first sign of pain or inflammation of a tendon (for example in your ankle, wrist, elbow, shoulder or knee), stop taking Avelox, contact your doctor and rest the painful area. Avoid any unnecessary exercise, as this might increase the risk of a tendon rupture.
- If you feel sudden, severe pain in your abdomen, chest or back, which can be symptoms of aortic aneurysm and dissection, go immediately to an emergency room. Your risk may be increased if you are being treated with systemic corticosteroids.
- If you start experiencing a rapid onset of shortness of breath, especially when you lie down flat in your bed, or you notice swelling of your ankles, feet or abdomen, or a new onset of heart palpitations (sensation of rapid or irregular heartbeat), you should inform a doctor immediately.
- If you are elderly with existing kidney problems take care that your fluid intake is sufficient because dehydration may increase the risk of kidney failure.
- If your eyesight becomes impaired or if your eyes seem to be otherwise affected, consult an eye specialist immediately (see sections 2. Driving and using machines and 4. Possible side effects).
- Fluoroquinolone antibiotics may cause an increase of your blood sugar levels above normal levels (hyperglycemia), or lowering of your blood sugar levels below normal levels (hypoglycaemia), potentially leading to loss of consciousness (hypoglycaemic coma) in severe cases (see section 4. Possible side effects). If you suffer from diabetes, your blood sugar should be carefully monitored.
- Quinolone antibiotics may make your skin become more sensitive to sunlight or UV light. You should avoid prolonged exposure to sunlight or strong sunlight and should not use a sunbed or any other UV lamp while using Avelox.
- There is limited experience on use of sequential intravenous/oral Avelox for the treatment of infection of the lungs (pneumonia) acquired outside the hospital.
- The efficacy of Avelox in the treatment of severe burns, infections of deep tissue and diabetic foot infections with osteomyelitis (infections of the bone marrow) has not been established.
This medicine must not be administered to children and adolescents under the age of 18 because efficacy and safety have not been established for this age group (see section Do not use Avelox).
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines besides Avelox.
For Avelox, be aware of the following:
- If you are using Avelox and other medicines that affect your heart there is an increased risk for altering your heart rhythm. Therefore, do not use Avelox together with the following medicines: Medicines that belong to the group of anti-arrhythmics (e.g. quinidine, hydroquinidine, disopyramide, amiodarone, sotalol, dofetilide, ibutilide), antipsychotics (e.g. phenothiazines, pimozide, sertindole, haloperidol, sultopride), tricyclic antidepressants, some antimicrobials (e.g. saquinavir, sparfloxacin, intravenous erythromycin, pentamidine, antimalarials particularly halofantrine), some antihistamines (e.g. terfenadine, astemizole, mizolastine), and other medicines (e.g. cisapride, intravenous vincamine, bepridil and diphemanil).
- You must tell your doctor if you are taking other medicines that can lower your blood potassium levels (e.g. some diuretics, some laxatives and enemas [large doses] or corticosteroids [anti-inflammatory drugs], amphotericin B) or cause a slow heart rate because these can also increase the risk of serious heart rhythm disturbances while using Avelox.
- If you are currently taking oral anti-coagulants (e.g. warfarin), it may be necessary for your doctor to monitor your blood clotting times.
The effect of Avelox is not influenced by food including dairy products.
Do not use Avelox if you are pregnant or breast-feeding.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Animal studies do not indicate that your fertility will be impaired by using this medicine.
Avelox may make you feel dizzy or light-headed, you may experience a sudden, transient loss of vision, or you might faint for a short period. If you are affected in this way do not drive or operate machinery.
This medicine contains 787 milligram (approximately 34 millimol) sodium (main component of cooking/table salt) in each bottle with 250 milliliter solution for infusion. This is equivalent to 39.35% of the recommended maximum daily dietary intake of sodium for an adult.
Avelox will always be given to you by a doctor or healthcare professional.
The recommended dose for adults is one bottle once daily.
Avelox is for intravenous use. Your doctor should ensure that the infusion is given at a constant flow over 60 minutes.
No adjustment of the dose is required in elderly patients, patients with a low bodyweight or in patients with kidney problems.
Your doctor will decide on the duration of your treatment with Avelox. In some cases your doctor may start your treatment with Avelox solution for infusion and then continue your treatment with Avelox tablets.
The duration of treatment depends upon the type of infection, and how well you respond to treatment but the recommended durations of use are:
- Infection of the lungs (pneumonia) acquired outside the hospital 7 - 14 days
Most patients with pneumonia were switched to oral treatment with Avelox tablets within 4 days.
- Infections of the skin and soft tissue 7 - 21 days
For patients with complicated skin and skin structure infections the mean duration of intravenous treatment was approximately 6 days and the average overall duration of treatment (infusion followed by tablets) was 13 days.
It is important that you complete the course of treatment, even if you begin to feel better after a few days. If you stop using this medicine too soon your infection may not be completely cured, the infection may return or your condition may get worse, and you may also create a bacterial resistance to the antibiotic.
The recommended dose and duration of treatment should not be exceeded (see section 2. What you need to know before you are administered Avelox, Warnings and precautions).
If you are concerned that you may have received too much Avelox, contact your doctor immediately.
If you are concerned that you may have missed a dose of Avelox, contact your doctor immediately.
If the treatment with this medicine is stopped too soon your infection may not be completely cured. Consult your doctor if you wish to stop the treatment with Avelox solution for infusion or Avelox tablets before the end of the course of treatment.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
The most serious side effects observed during the treatment with Avelox are listed below:
If you notice
