Side effects.
In placebo-controlled studies 9% patients, receiving sibutramine (n=2068) and 7% patients, placebo (n=884), stopped treatment because of side effects.
In placebo-controlled studies, the most common side effects were dry mouth, anorexia, insomnia, constipation, headache.
The following are the side effects, which were observed in patients, taking sibutramine, a frequency ≥1% and more often, than placebo. Next to the name contains the frequency of occurrence of side effects in the group treated with sibutramine, in brackets - the same data in the placebo group.

Other: generalized edema - 1,2% (0,8%).
Cooperation.
Inhibitors of microsomal oxidation, incl. inhibitors of CYP3A4 cytochrome P450 (ketoconazole, Erythromycin, cyclosporin and others.) sibutramine reduced clearance. Funds, having serotonergic activity, increase the risk of serotonin syndrome (ažitaciâ, Sweating, diarrhea, fever, arrhythmia, convulsions, etc..).
Overdose.
Symptoms: increased severity of side effects, most often - tachycardia, increased blood pressure, headache and dizziness.
Treatment: administration of activated charcoal, simptomaticheskaya therapy, monitoring vital functions, with an increase in blood pressure and tachycardia - appointment of beta-blockers.
Dosing and Administration.
Inside, 1 once a day (morning), the initial dose - 10 mg (bad Portability can receive 5 mg); in the case of lack of effectiveness through 4 week increase the dose to 15 mg / day. Duration of treatment - 1 year.
Precautions.
It is necessary to control the level of blood pressure and heart rate every 2 in the first week 2 months of treatment, and then - 1 once a month. In patients with hypertension when blood pressure >145/90 mmHg. monitoring should be carried out carefully and more, in the case of double-registered rise in blood pressure >145/90 mmHg. treatment should be discontinued. The emergence during therapy of chest pain, progressive dyspnea (respiratory failure) and edema of the lower extremities may indicate the development of pulmonary hypertension (In this case, you must always consult a doctor).
It avoids simultaneous administration of drugs, prolonging the QT interval (astemizol, terfenadine, antiarrhythmic and other means), means, containing ephedrine, phenylpropanolamine, Pseudoephedrine etc.. (increase the risk of blood pressure and heart rate increase), and the other with a central anorectics mechanism of action. Precautions should be prescribed in the background gipokalie- and hypomagnesemia, in violation of liver and kidney function, and mild to moderate severity.
Women of childbearing age during treatment should use appropriate contraceptive measures.
It will be appreciated, that sibutramine may reduce saliva and contribute to the development of caries, periodontal disease, candidiasis and discomfort in the mouth. During treatment, it is recommended to limit the consumption of alcohol.
Should not be used during the drivers of vehicles and people, skills relate to the high concentration of attention.
Cautions.
Application is possible only in cases, when all other measures, aimed at the reduction of body weight, ineffective. Treatment should be under medical supervision, with experience correction obesity as part of combination therapy (diet, changes in eating habits and lifestyle, increasing physical activity). Reception period at a dose 15 mg should be limited in time.
