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.
Avelox is used in patients aged 18 years and above for treating the following bacterial infections when caused by bacteria against which moxifloxacin is active. Avelox should only be used to treat these infections when usual antibiotics cannot be used or have not worked:
Infection of the sinuses, sudden worsening of long term inflammation of the airways or infection of the lungs (pneumonia) acquired outside the hospital (except severe cases).
Mild to moderate infections of the female upper genital tract (pelvic inflammatory disease), including infections of the fallopian tubes and infections of the uterus mucous membrane.
Avelox tablets are not sufficient on their own for treating this kind of infection. Therefore, another antibiotic in addition to Avelox tablets should be prescribed by your doctor for the treatment of infections of the female upper genital tract (see section 2. What you need to know before you take Avelox, Warnings and precautions, Talk to your doctor before taking Avelox).
If the following bacterial infections have shown improvement during initial treatment with Avelox solution for infusion, Avelox tablets may also be prescribed by your doctor to complete the course of therapy: Infection of the lungs (pneumonia) acquired outside the hospital, infections of the skin and soft tissue.
Avelox tablets should not be used to initiate therapy for any type of infections of the skin and soft tissue or in severe infections of the lungs.
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 are breast-feeding.
- If you are under 18 years of age.
- If you have previously had problems with your tendons related to treatment with quinolone antibiotics (see section Warnings and Precautions … and section 4. Possible side effects).
- If you were born with or have
- any condition with abnormal heart rhythm (seen on ECG, electrical recording of the heart)
- a salt imbalance in the blood (especially low levels of potassium or magnesium in the blood)
- a very slow heart rhythm (called ‘bradycardia’)
- a weak heart (heart failure)
- 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 increased liver enzymes (transaminases) higher than 5 times the upper normal limit.
Talk to your doctor before taking Avelox
- 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 taking Avelox (see also sections Do not take and Other medicines and Avelox).
- If you suffer from epilepsy or a condition which makes you likely to have convulsions talk to your doctor before taking Avelox.
- If you have or have ever had any mental health problems, consult your doctor before taking Avelox.
- If you suffer from myasthenia gravis (abnormal muscle fatigue leading to weakness and in serious cases paralysis), taking 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 a family history of aortic aneurysm or aortic dissection or other risk factors or predisposing conditions (e.g. connective tissue disorders such as Marfan syndrome, or vascular Ehlers-Danlos syndrome, or vascular disorders such as Takayasu arteritis, giant cell arteritis, Behcet´s disease, high blood pressure, or known atherosclerosis).
- If you or any member of your family have glucose-6-phosphate dehydrogenase deficiency (a rare hereditary disease), tell your doctor, who will advise whether Avelox is suitable for you.
- If you have a complicated infection of the female upper genital tract (e.g. associated with an abscess of the fallopian tubes and ovaries or of the pelvis), for which your doctor considers an intravenous treatment necessary, treatment with Avelox tablets is not appropriate.
- For the treatment of mild to moderate infections of the female upper genital tract your doctor should prescribe another antibiotic in addition to Avelox. If there is no improvement in symptoms after 3 days of treatment, please consult your doctor.
- 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. Therefore, the recommended dosage should be followed.
- There is a rare chance that you may experience a severe, sudden allergic reaction (an anaphylactic reaction/shock) even with the first dose. Symptoms include tightness in the chest, feeling dizzy, feeling sick or faint, or dizziness when standing up. If so, stop taking Avelox and seek medical advice 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). If you suddenly feel unwell and/or are being sick and also have yellowing of the whites of the eyes, dark urine, itching of the skin, a tendency to bleed or liver induced disease of the brain (symptoms of a reduced liver function or a rapid and severe inflammation of the liver) please contact your doctor before taking any more tablets.
- If you develop a skin reaction or blistering / peeling of the skin and/or mucosal reactions (see section 4. Possible side effects) contact your doctor immediately before you continue treatment.
- Quinolone antibiotics, including Avelox, may cause convulsions. If this happens, stop taking Avelox and contact your doctor immediately.
- You may 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, inform your doctor immediately prior to continuing treatment with Avelox.
- 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, stop taking Avelox and inform your doctor immediately.
- You may develop diarrhoea whilst 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 taking Avelox immediately and consult your doctor. You should not take medicines that stop or slow down bowel movement.
- Avelox may cause pain and inflammation of your tendons, even within 48 hours of starting treatment and up to several months after discontinuing Avelox therapy. The risk of inflammation and rupture of tendons is increased if you are elderly or if you are also taking corticosteroids. At the first sign of any pain or inflammation you should stop taking Avelox, rest the affected limb(s) and consult your doctor immediately. Avoid any unnecessary exercise, as this might increase the risk of a tendon rupture (see sections Do not take Avelox… and 4. Possible side effects).
- If you feel sudden, severe pain in your abdomen, chest or back, go immediately to an emergency room.
- If you are elderly and have kidney problems make sure that you drink plenty whilst taking Avelox. If you get dehydrated this 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 Driving and using machines and 4. Possible side effects).
- Fluoroquinolone antibiotics may cause disturbances in blood sugar, including both a decrease in blood sugar below normal levels (hypoglycemia) and an increase in blood sugar above normal levels (hyperglycemia). In patients treated with Avelox, disturbances in blood sugar occurred predominantly in elderly patients receiving concomitant treatment with oral antidiabetic medicines that lower blood sugar (e. g. sulfonylurea) or with insulin. If you suffer from diabetes, your blood sugar should be carefully monitored (see section 4. Possible side effects).
- 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 taking Avelox.
- 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.
Do not give this medicine 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 take Avelox).
Tell your doctor or pharmacist about any other medicines that you are taking, took recently or might take.
For Avelox, be aware of the following:
- If you are taking Avelox and other medicines that affect your heart there is an increased risk for altering your heart rhythm. Therefore, do not take 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)
- 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 [high 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 taking Avelox.
- Any medicine containing magnesium or aluminium (such as antacids for indigestion), iron, zinc or didanosine or any medicine containing sucralfate (to treat stomach disorders) can reduce the action of Avelox tablets. Take your Avelox tablet 6 hours before or after taking the other medicine.
- Taking any medicine containing charcoal at the same time as Avelox tablets reduces the action of Avelox. It is recommended that these medicines are not used together.
- If you are currently taking drugs to thin your blood (oral anti-coagulants such as warfarin), it may be necessary for your doctor to monitor your blood clotting time.
Avelox can be taken with or without food (including dairy products).
Do not take 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 taking this medicine.
Animal studies do not indicate that your fertility will be impaired by taking this medicine.
Avelox may make you feel dizzy or light-headed, you may experience a sudden, transient loss of vision, or you may faint for a short period. If you are affected do not drive or operate machinery.
If you have been told by your doctor that you have an intolerance to some sugars, speak to your doctor before taking Avelox.
This medicine contains less than 1 millimol sodium (23 milligramm) per film-coated tablet, that is to say essentially “sodium-free”.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose for adults is one 400mg film-coated tablet once daily.
Avelox tablets are for oral use. Swallow the tablet whole (to mask the bitter taste) and with plenty of liquid. You can take Avelox with or without food. Try to take the tablet at approximately the same time each day.
The same dose can be taken by elderly patients, patients with a low bodyweight or in patients with kidney problems.
The time you will take Avelox for depends on your infection. Unless your doctor tells you otherwise, your treatment will be as follows:
- for sudden worsening (acute exacerbation) of chronic bronchitis 5 - 10 days
- for infection of the lungs (pneumonia) except for pneumonia which starts during a stay in hospital 10 days
- for acute infection of the sinuses (acute bacterial sinusitis) 7 days
- Mild to moderate infections of the female upper genital tract (pelvic inflammatory disease), including infection of the fallopian tubes and infection of the uterus mucous membrane 14 days
When Avelox film-coated tablets are used to complete a course of therapy started with Avelox solution for infusion, 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 film-coated tablets within 4 days.
- Infections of the skin and soft tissue 7 -21 days
Most patients with infections of the skin and soft tissue were switched to oral treatment with Avelox film-coated tablets within 6 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 taking Avelox too soon your infection may not be completely cured and the infection may return or your condition may get worse. The bacteria causing your infection may become resistant to Avelox.
The recommended dose and duration of treatment should not be exceeded (see section 2. What you need to know before you take Avelox, Warnings and precautions).
If you take more than the prescribed one tablet a day, get medical help immediately. Try to take any remaining tablets, the packaging or this leaflet with you to show the doctor or pharmacist what you have taken.
If you forget to take your tablet you should take it as soon as you remember on the same day. If you do not remember on the same day, take your normal dose (one tablet) on the next day. Do not take a double dose to make up for a forgotten dose.
If you are unsure about what to do ask your doctor or pharmacist.
If you stop taking this medicine too soon your infection may not be completely cured. Talk to your doctor if you wish to stop taking your tablets before the end of the course of treatment.
If you have any further questions about this medicine, ask your doctor or pharmacist.
