Classification of the incidence of adverse events according to recommendations
World Health Organization (WHO):
very often ≥1 / 10;
often from ≥ 1/100 to <1/10;
infrequently from ≥ 1/1000 to <1/100;
rarely from ≥ 1/10000 to <1/1000;
very rarely <1/10000, including individual messages;
frequency is unknown - but it is not possible to establish the frequency of occurrence of available data.
Disturbances from the nervous system:
often - dizziness, * headache *, asthenia (in patients with CHF), fatigue, sleep disturbances, depression, anxiety;
infrequently - asthenia (in patients with arterial hypertension or angina pectoris), drowsiness or insomnia, depression;
rarely - hallucinations, "nightmarish" dreams, confusion or short-term memory loss, myasthenia gravis, tremor, muscle cramps.Usually, these phenomena are of an easy nature and usually take place within 1-2 weeks after the start of treatment.
Disturbances on the part of the organ of sight:
rarely - impaired vision, reduced secretion of tear fluid;
very rarely - dryness and soreness of the eyes, conjunctivitis.
Violations from the organ of hearing and labyrinth:
rarely - noise in the ears, hearing loss, ear pain.
Heart Disease:
very often bradycardia;
often - aggravation of CHF symptoms (in patients with CHF);
infrequently infringement AV conduction, decompensation of CHF;
rarely - withdrawal syndrome (increased angina attacks, increased blood pressure).
Vascular disorders:
often marked decrease in blood pressure (especially in patients with CHF), manifestation of angiospasm (increased peripheral circulatory disturbance, coldness of the lower extremities, paresthesia);
infrequently - orthostatic hypotension, peripheral edema.
Gastrointestinal disorders:
often - nausea, vomiting, diarrhea, constipation, dryness of the oral mucosa, abdominal pain;
very rarely - a change in taste.
Disturbances from the liver and bile ducts:
rarely - hepatitis.
Disturbances from the respiratory system, chest and mediastinal organs:
infrequently - bronchospasm in patients with bronchial asthma or airway obstruction in anamnesis, chest pain;
rarely - nasal congestion.
Immune system disorders:
rarely - skin itching, skin rash, hives, allergic rhinitis.
Disturbances from the skin and subcutaneous tissues:
rarely - hypersensitivity reactions, such as pruritus, rash, skin hyperemia, increased sweating, exanthema, psoriasis-like skin reactions;
very rarely - exacerbation of psoriasis symptoms, alopecia.
Disturbances from muscular, skeletal and connective tissue:
infrequently - arthralgia, pain in the back.
Laboratory and instrumental data:
rarely - increased activity of "hepatic" transaminases (alanine aminotransferase, aspartate aminotransferase), increased bilirubin concentration, hypertriglyceridemia;
in some cases - thrombocytopenia, leukopenia, agranulocytosis.
Disorders from the reproductive system and mammary glands:
rarely - a violation of potency, a weakening of the libido.
* In patients with hypertension or angina pectoris, especially these symptoms appear at the beginning of the course of treatment.Usually, these symptoms are mild and usually occur within 1-2 weeks after the start of treatment.
