Do NOT take MOFLOXX:
- If you are known to be allergic to moxifloxacin, any other component of the tablets or to any other quinolone antibiotics.
- If you or your child are younger than 18 years of age.
- If you are pregnant or breastfeeding (see ʺPregnancy and breastfeedingʺ).
- If you have previously experienced side effects with the use of quinolone/fluoroquinolone antibiotics relating to your joints, muscles, ligaments, nerves, central nervous system (brain), epilepsy or mental health (psychiatric disorder).
- If you were born with or have any condition with abnormal rhythm whether related to QT time prolongation or not (seen on ECG, electrical recording of the heart).
- If you have recently been diagnosed with electrolyte disturbances, such as low blood potassium levels.
- If you have any heart disease, especially heart failure or any disease affecting the blood supply to your heart (also known as coronary heart disease, ischaemic heart disease, heart attack or angina).
- If you are taking other medicines that result in abnormal heart rate or rhythm tracing (ECG) e.g. (prolongation of the “QT time”).
- If you suffer from liver problems.
- If you have moderate to severe impairment of your kidney function and are treated with ACE inhibitors/angiotensin receptor blockers. Ask your doctor if you are not sure.
- If you have an enlargement or “bulge” of a large blood vessel (aortic aneurysm) or a previous episode of aortic dissection (a tear in the aortic wall) or a family history of aortic aneurysm/dissection or have other risk factors or existing predisposing conditions.
- If you have mitral valve or aortic valve regurgitation (when your heart's mitral or aortic valve does not close tightly, causing blood to flow back into the heart instead of pumping out).
Take special care with MOFLOXX:
The presence of other medical conditions may affect the use of MOFLOXX. Tell your doctor or pharmacist if you have any of the following conditions as you may require a lower dose or special monitoring:
- Any condition that requires the use of medicines that may slow down your heart rate, such as cisapride, erythromycin (another antibiotic), antipsychotic medication (for the treatment of psychosis), antidepressants or medicines for irregular heart beat (e.g. disopyramide, amiodarone or sotalol) (see ʺDo NOT take MOFLOXX if youʺ and ʺTaking other medicines with MOFLOXXʺ).
- If you are currently taking other medicines that can reduce blood potassium levels (see ʺDo NOT take MOFLOXX if youʺ and ʺTaking other medicines with MOFLOXXʺ). You should inform your doctor of any other medicines that you are taking, including over-the-counter medicines, before you start taking MOFLOXX.
- Any personal or family history of heart problems / conditions.
- Convulsions, or epileptic seizures or fits since treatment with MOFLOXX may lead to convulsions in certain patients (see Do not take MOFLOXX).
- Any central nervous system disorder, such as reduced blood flow to the brain due to atherosclerosis. Treatment with MOFLOXX may cause central nervous system (CNS) events, including dizziness, confusion, tremors, hallucinations (hearing voices or seeing things that are not real), depression, anxiety, sleeplessness, nightmares or paranoia, agitation, nervousness and rarely suicidal thoughts or acts. You may experience some of these reactions following the first dose of MOFLOXX. If you experience any of these adverse reactions, you should immediately report them to your doctor.
- If you have been diagnosed with or have a history of any psychiatric disease, as you may develop psychiatric reactions even after the first dose of MOFLOXX (see Do not take MOFLOXX). In some people depression or psychotic reactions have progressed to suicidal thoughts and self-injurious behaviour, such as suicide attempts (see ʺPOSSIBLE SIDE - EFFECTSʺ). If you develop these reactions, treatment with MOFLOXX should be stopped. Your doctor may prescribe alternative medicine(s).
- Allergic reactions to other antibiotics, especially if you had an allergic reaction to other fluoroquinolone antibiotics. Symptoms of an allergic reaction may include hives, itching, skin rash, shortness of breath, swelling of the lips, tongue or throat, and tingling, and may progress to loss of consciousness, severely low blood pressure and even death. Some patients have experienced allergic reactions after the first dose of MOFLOXX. You should immediately report to your doctor if you develop a skin rash or any other sign of an allergic reaction, such as those listed here.
- If you have been diagnosed with myasthenia gravis (an inborn autoimmune disorder of the muscles) (see “Do Not Take Mofloxx”).
- If you are elderly and have any kidney problems. You should maintain adequate fluid intake because dehydration may increase your risk of kidney failure. You should take MOFLOXX with or without meals, and drink plenty of fluids.
- If you have been diagnosed with or have a family history of glucose-6-phosphate dehydrogenase deficiency (an inborn condition).
- 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, Vascular Ehlers-Danlos syndrome, Takayasu arteritis, giant cell arteritis, Behcet’s disease, high blood pressure or known atherosclerosis (see “Do Not Take Mofloxx”).
- MOFLOXX may interfere with the interpretation of diagnostic culture tests for tuberculosis.
- If you have moderate to severe impairment of your kidney function, or if you are elderly and are treated with ACE inhibitors/angiotensin receptor blockers to control your blood pressure as this may cause further injury to your kidneys (see “Do Not Take Mofloxx”).
Treatment with antibiotics, including MOFLOXX, may lead to the development of conditions known as antibiotic-associated diarrhoea (loose stools) and antibiotic-associated colitis, including pseudomembranous colitis, which cause an overgrowth of bacteria in the colon that are not sensitive to MOFLOXX. This condition is characterised by offensive-smelling diarrhoea (watery and severe), which may be bloody, severe stomach pain or cramps, fever, and loss of appetite. You should immediately report these symptoms to your doctor.
Another potentially serious complication of treatment with MOFLOXX is the development of tendon disorders, such as inflammation of a tendon (also known as tendinitis) or tendon rupture. This may develop from 2 to 42 days after the start of treatment with MOFLOXX. In the elderly and with concurrent use of corticosteroids the risk of tendon disorders may increase. If you experience pain, swelling, or redness over a tendon you should refrain from exercise and immediately report to your doctor. You should inform your doctor if you experience pain, burning, tingling, numbness or weakness while taking MOFLOXX, as these may be symptoms of a nerve condition and your doctor may decide to prescribe alternative medicine(s) for you (see ʺPOSSIBLE SIDE EFFECTSʺ).
You should contact your doctor if you develop weakness, yellow discolouration of the skin or whites of the eyes with or without pain over the liver area, dark urine, or bleeding tendency, as this may be due to liver disease, which may be life-threatening (see ʺPOSSIBLE SIDE EFFECTSʺ). Your doctor may decide to monitor your liver function (see ʺDo NOT take MOFLOXX if youʺ).
Tell your doctor if you have been diagnosed with mitral valve or aortic valve regurgitation (when your heart's mitral or aortic valve does not close tightly, causing blood to flow back into the heart instead of pumping out). Your doctor will perform a thorough examination of your heart, including an echocardiogram, since MOFLOXX should not be taken if you have mitral valve or aortic valve regurgitation (see ʺDo not take MOFLOXXʺ).
If you develop any blister-forming skin rash, or blisters on mucous membranes, you should report to your doctor immediately (see ʺPOSSIBLE SIDE - EFFECTSʺ).
If you develop poor or blurred vision, you should consult an eye specialist immediately (see ʺPOSSIBLE SIDE EFFECTSʺ).
Treatment with MOFLOXX may interfere with biological tests used in the diagnosis of certain diseases and cause false negative test results. Please also note that treatment with MOFLOXX may lead to:
- Electrocardiogram (ECG) changes.
- Dizziness, palpitations and fainting spells, which you should report to your doctor immediately. Women and the elderly may be more sensitive to these effects and therefore special caution is required.
- The development of a skin rash or discolouration on sun exposed areas (known as phototoxicity or photosensitivity). In keeping with good medical practice, you should avoid excessive sunlight or artificial ultraviolet light (e.g. tanning beds). If sunburn-like reactions or skin eruptions occur, contact your doctor.
