The observed adverse events are usually mild and transitory, occur during the continuation of treatment or after a reduction in the dose of Anafranil.They do not always correlate with the concentration of the active substance in the blood plasma or with the dose of the drug. Some undesirable phenomena, such as fatigue, sleep disorders, agitation, anxiety, constipation, dry mouth, are often difficult to distinguish from manifestations of depression.
In case of serious reactions from the nervous system or mental status Anafranil should be canceled.
Elderly people are particularly sensitive to the action of Anafranil on the nervous system, cardiovascular system, the effect of the drug on mental status, and also on the anticholinergic effect of Anafranil.
Metabolism and excretion of drugs at this age can be slowed down, which leads to an increase in the concentration of drugs in the blood plasma when using therapeutic doses.
Undesirable reactions are listed by frequency, starting with the most frequentx: emerging
"Often" - ≥ 1/10, "often" - ≥1/100-<1/10, "sometimes" - 1 / 1000- <1 /100, "rarely" - 1 / 10000- <1 /1000, "very rarely" - <1 /10000, including individual cases.
From the central and peripheral nervous system. Mental status: very often - drowsiness, a sense of fatigue, anxiety,increased appetite; often confusion, disorientation, hallucinations (especially in elderly patients and patients with Parkinson's disease), anxiety, agitation, sleep disorders, manic state, hypomanic state, aggressiveness, memory impairment, depersonalization, increased depression, attention deficit disorder, insomnia, nightmares, yawning; sometimes: the activation of the symptoms of psychosis.
Neurological status: very often - dizziness, tremor, headache, myoclonus;
often - delirium, speech disorders, paresthesia, muscle weakness, increased muscle tone;
sometimes - cramps, ataxia; very rarely - changes in the electroencephalogram, increase in body temperature.
AnTikhoninergic effects: very often - dry mouth, excessive sweating, constipation, disruption of accommodation, blurred vision ("vein before the eyes "), urination disorders, often - hot flashes, mydriasis, very rarely - glaucoma, urinary retention.
From the cardiovascular system: often - sinus tachycardia, palpitations, orthostatic hypotension, clinically insignificant changes on the ECG
(e.g., an interval ST or T wave) in patients without a pathology of the heart; sometimes - arrhythmias, increased blood pressure; very rarely - violations of intracardiac conduction (for example, the expansion of the complex QRS, lengthening the interval QT, interval changes PQ, bundle branch blockade, bi-directional spindle-shaped ventricular tachycardia ("torsade de points"), especially in patients with hypokalemia).
From the gastrointestinal tract (FTOT): very often - nausea; often - vomiting, abdominal discomfort, diarrhea, anorexia.
From the side of the liver: often - increased levels of transaminases; very rarely, hepatitis with or without jaundice.
Dermatological reactions: often - allergic skin reactions (rash, urticaria), photosensitization, pruritus; very rarely - swelling (local or general), hair loss.
From the endocrine system and metabolism: very often - weight gain, libido and potency disorders; often - galactorrhea, enlarged mammary glands; very rarely - the syndrome of inadequate secretion of antidiuretic hormone.
Hypersensitivity reactions: very rarely - allergic alveolitis
(pneumonitis) with or without eosinophilia, systemic anaphylactic/anafylactoid
reactions, including hypotension.
On the part of the hematopoiesis system: very rarely - leukopenia, agranulocytosis, eosinophilia, thrombocytopenia, purpura.
From the sense organs: often - the violation of taste sensations, noise in the ears.
The withdrawal syndrome: after sudden withdrawal or rapid dose reduction Anafranil often have the following symptoms: nausea, vomiting, abdominal pain, diarrhea, insomnia, headache, irritability, anxiety.
