The observed adverse events are usually mild and transient, disappear when the Ludomil® drug is continued or if its dose is reduced. They do not always clearly correlate with the concentration of the active substance in the blood plasma or with the dose of the drug. Often there are difficulties in the differential diagnosis of certain undesirable phenomena and symptoms of depression: feelings of fatigue, sleep disturbances, agitation, anxiety, constipation, dry mouth.
When developing serious adverse events, for example, from the central nervous system, the drug Ludomil® should be discontinued.
The elderly are particularly sensitive to the m-cholinoblocking effects of Ludomil®, as well as its effect on the central nervous and cardiovascular systems. In elderly patients with a reduced ability to metabolize and withdraw drugs, the risk of a significant increase in the concentration of active substance in the blood plasma when the drug is administered in therapeutic doses increases.
Below are the undesirable phenomena observed with the use of both the drug Ludomil® and tricyclic antidepressants listed in frequency, starting with the most frequent. The frequency of unwanted reactions is estimated as follows: very often (1/10); often (1/100, <1/10); infrequently (1 / 1,000, <1/100); rarely (1 / 10,000, <1 / 1,000); very rarely (<1 / 10,000), including individual messages.
From the central and peripheral nervous system: very often - drowsiness, dizziness, headache, tremor, myoclonus; often - sedation, memory loss, attention disturbance, paresthesia, dysarthria; rarely - cramps, akathisia, ataxia; very rarely - dyskinesia, fainting, a violation of taste.
Mental disorders: often - anxiety, anxiety, agitation, manic disorders, violation of libido, aggressiveness, sleep disturbance, insomnia, nightmares, increased symptoms of depression; rarely - oppression of consciousness of various degrees, delirious disorders, hallucinations (mainly in elderly patients), increased excitability; very rarely - the activation of symptoms of psychosis, depersonalization.
From the cardiovascular system: often - sinus tachycardia, palpitations, orthostatic hypotension, "hot flashes" (sensation of heat); rarely - arrhythmia; very rarely - violations of intracardiac conduction (eg, expansion of the QRS complex, bundle branch blockade, changes in the PQ interval), prolongation of the QT interval, ventricular tachycardia, ventricular fibrillation, torsade des pointes, purpura.
There are reports of individual cases of ventricular tachycardia, ventricular fibrillation, bi-directional spindle-shaped ventricular torsade des pointes (fatal).
From the digestive system: very often - dry mouth; often - nausea, vomiting, discomfort in the abdomen, constipation; rarely diarrhea; very rarely - stomatitis, hepatitis, accompanied or not accompanied by jaundice.
From the skin: often - allergic dermatitis, rash, hives, photosensitization, hyperhidrosis; very rarely - itching, skin vasculitis, alopecia, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis.
From the endocrine system and metabolism: often - increased appetite, weight gain; very rarely - the syndrome of inadequate secretion of antidiuretic hormone.
From the respiratory system: very rarely - allergic alveolitis (with or without eosinophilia), interstitial lung diseases (including subacute interstitial pneumonitis), bronchospasm, nasal congestion.
On the part of the hematopoiesis system: very rarely - leukopenia, agranulocytosis, eosinophilia, thrombocytopenia.
From the sense organs: often - "blurring" of vision, violation of accommodation; very rarely - noise in the ears.
From the side of the musculoskeletal system and connective tissue: often - muscle weakness.
From the excretory and reproductive systems: often - urination disorders, erectile dysfunction; very rarely - urinary retention, mammary gland hypertrophy, galactorrhea.
Common disorders and reactions at the site of administration: very often fatigue; often - fever; very rarely - swelling (local or general).
Laboratory and instrumental studies: often - electrocardiographic disorders (for example, changes in the ST segment and T wave); rare - marked increase in blood pressure, deviation of functional hepatic samples; very rarely - violations on the electroencephalogram.
Other: very rarely - falls, dental caries.
The manifestation of the syndrome of "withdrawal"
After a sudden withdrawal or rapid dose reduction, the following symptoms rarely occur: nausea, vomiting, abdominal pain, diarrhea, insomnia, headache, increased excitability, anxiety, increased depression or relapse of depressive mood disorders.
Fractures of bones
In patients aged ≥50 years, receiving selective serotonin reuptake inhibitors and tricyclic antidepressants, there was an increased risk of fractures, the mechanism of occurrence of which is not known.
If any of the side effects listed in the manual are aggravated, or if you notice any other side effects not listed in the instructions, tell your doctor.
