In some cases, after the first use of the drug may develop hypersensitivity and allergic reactions, which should immediately inform the doctor. Very rarely even after the first use of the drug, anaphylactic reactions can progress to a life-threatening anaphylactic shock.In these cases, treatment with moxifloxacin should be discontinued and necessary medical measures (including anti-shock) should be carried out.
With the use of moxifloxacin in some patients, lengthening of the interval QT.
A drug moxifloxacin should be used with caution in women and elderly patients. Because women have a longer interval than men QT, they may be more sensitive to drugs that extend the interval QT. Elderly patients are also more prone to the effects of drugs that affect the interval QT.
Degree of lengthening interval QT may increase with increasing drug concentration, therefore, do not exceed the recommended dose. However, in patients with pneumonia, the correlation between the concentration of moxifloxacin in the blood plasma and the lengthening of the interval QT was not noted. Interval lengthening QT is associated with an increased risk of ventricular arrhythmias, including polymorphic ventricular tachycardia. None of the 9,000 patients who received moxifloxacin, there were no cardiovascular complications and lethal cases associated with lengthening the interval QT. However, in patients with predisposing arrhythmias, the risk of developing ventricular arrhythmias may increase with moxifloxacin.
Concerning moxifloxacin contraindicated in: changes in the electrophysiological parameters of the heart, expressed in the lengthening of the interval QT: congenital or acquired; documented lengthening interval QT, electrolyte disturbances, especially uncorrectable hypokalemia; clinically significant bradycardia; clinically significant heart failure with a reduced fraction of the left ventricular ejection; presence in the anamnesis of rhythm disturbances, accompanied by clinical symptoms; application with other drugs that extend the interval QT (see the section "Interaction with other medicinal products").
Moxiflocacin should be used with caution: in patients with potentially proarrhythmic conditions, such as acute myocardial ischemia and cardiac arrest; in patients with cirrhosis of the liver (since this category of patients can not exclude the risk of developing an extension of the interval QT).
Disglycemia. As in the case of other fluoroquinolones, when the drug is used moxifloxacin there was a change in the concentration of glucose in the blood, including hypo- and hyperglycemia. Against the background of drug therapy moxifloxacin dysglycemia occurred predominantly in elderly patients with diabetes mellitus receiving concomitant therapy with oral hypoglycemic drugs (eg, sulfonylureas) or insulin. When performing treatment in patients with diabetes, careful monitoring of the concentration of glucose in the blood is recommended.
When moxifloxacin was taken, cases of fulminant hepatitis, potentially leading to the development of hepatic insufficiency (including fatal cases) were reported (see section "Side effect"). The patient should be informed that if symptoms of hepatic insufficiency occur, the doctor should be consulted before continuing with moxifloxacin.
When moxifloxacin was taken, cases of development of bullous skin lesions (Stevens-Johnson syndrome, toxic epidermal necrolysis) were reported. The patient should be informed that in case of symptoms of skin or mucous membrane damage, the doctor should be consulted before continuing with moxifloxacin.
The use of drugs quinolone series is associated with a possible risk of seizures. Moxifloxacin should be used with caution in patients with diseases of the central nervous system (CNS) and with conditions suspicious of CNS involvement predisposing to the occurrence of seizures or reducing the threshold of seizure activity.
The use of broad-spectrum antibacterial drugs, including moxifloxacin, is associated with a risk of developing pseudomembranous colitis associated with taking antibiotics. This diagnosis should be borne in mind in patients with moxifloxacin onset of severe diarrhea. In this case, the drug should be withdrawn and immediate therapy should be prescribed.
Preparations that inhibit the intestinal peristalsis are contraindicated in the development of severe diarrhea.
Moxifloxacin should be used with caution in patients with myasthenia gravis gravis in connection with a possible exacerbation of the disease.
Against the background of quinolone therapy, including moxifloxacin, especially in the elderly and patients receiving glucocorticosteroids, tendonitis and tendon rupture may develop.Cases which have arisen within several months after the end of treatment are described. At the first symptoms of pain or inflammation at the site of damage, stop taking the medication and unload the affected limb.
When applying quinolones, photosensitivity reactions are noted. However, in the conduct of preclinical, clinical studies, as well as with the use of moxifloxacin, no photosensitivity reactions were observed in practice. Nevertheless, patients receiving moxifloxacin, should avoid direct sunlight and ultraviolet light.
It is not recommended to use the drug in patients with complicated inflammatory diseases of the pelvic organs (for example, associated with tubo-ovarian or pelvic abscesses).
It is not recommended to use moxifloxacin for the treatment of infections caused by strains Staphylococcus aureus, resistant to methicillin (MRSA). In the case of suspected or confirmed infections caused by MRSA, should be prescribed treatment with appropriate antibacterial drugs (see the section "Pharmacodynamics"). Ability of the drug Moxifloxacin To suppress the growth of mycobacteria can cause in vitro interaction of moxifloxacin with a test for Mycobacterium spp., leading to false negative results in the analysis of samples of patients treated with moxifloxacin during this period.
In patients treated with quinolones, including moxifloxacin, described cases of sensory or sensorimotor polyneuropathy, leading to paresthesia, hypoesthesia, dysesthesia or weakness. Patients undergoing treatment with moxifloxacin should be warned of the need to seek immediate medical attention before continuing treatment in the event of symptoms of neuropathy, including pain, burning, tingling, numbness, or weakness (see "Side effect" section).
Reactions from the psyche may occur even after the first appointment of fluoroquinolones, including moxifloxacin. In very rare cases, depression or psychotic reactions progress to the occurrence of suicidal thoughts and behavior with a tendency to self-harm, including suicidal attempts (see "Side effect" section). If the patient develops such reactions, it is necessary to cancel the drug and take the necessary measures.Caution should be exercised when administering moxifloxacin to patients with psychoses and patients with a history of mental illness.
Because of the wide spread and growing incidence of infections caused by fluoroquinolone-resistant Neisseria gonorrhoeae, in the treatment of patients with inflammatory diseases of the pelvic organs, monotherapy with moxifloxacin should not be carried out. Except where the presence of a resistant to fluoroquinolones N. gonorrhoeae excluded. If there is no way to exclude the presence of fluoroquinolones resistant N. gonorrhoeae, it is necessary to resolve the issue of supplementing empirical therapy with moxifloxacin with an appropriate antibiotic that is active against N. gonorrhoeae (e.g., cephalosporin).
