If during therapy marked expansion of QT interval and QRS duration greater than 20%, there was a prolongation of PQ interval greater than 50%, an increase of frequency and severity of arrhythmias, QT prolongation greater than 500 msec., It is necessary to reduce the dosage or a time to stop therapy with, or analogs propanorm.

  • dry mouth, taste change, diarrhea or constipation, decreased appetite, nausea, bitter taste in the mouth, feeling of heaviness in the epigastric, cholestasis, liver function abnormalities, cholestatic jaundice;
  • dizziness, headache, diplopia, blurred vision, convulsions;
  • thrombocytopenia, increased bleeding time, the appearance of antinuclear bodies, agranulocytosis, leukopenia.
  • reduced potency, oligospermia;

  • hemorrhagic rash, bronchospasm, weakness.


Overdose propanorm Review can cause the following symptoms:

  • coma;
  • pulmonary edema;
  • AV-block.

If symptoms of overdose propanorm of reviews is necessary gastric lavage, defibrillation, enter the diazepam, dobutamine and spend symptomatic therapy.

Perhaps the use of the drug and analogs propanorm during pregnancy in the case of the balance of risks to the mother and fetus.

Drug Interactions

Propanorm and its analogs are not recommended to be combined with lidocaine, as there is a strengthening cardiodepressive effect.

In an application with propanorm:

  • increased plasma concentrations of cyclosporine, indirect anticoagulants, digoxin, metoprolol, propranolol;
  • enhanced warfarin;
  • tricyclic antidepressants, beta-blockers, anti-arrhythmic action is amplified;
  • local anesthetics increases the risk of CNS;
  • quinidine and propafenone cimetidine increases the concentration in plasma;
  • rifampicin reduced concentration propafenone plasma.
  • Amiodarone increases the risk of tachycardia type "pirouette";
  • drugs which depress AV-node and sinoatrial node, increasing the risk of side effects;
  • drugs which depress the bone marrow blood, increases the risk of myelosuppression.
