Adult Side Effects

Geleidingsstoornissen, torsade de pointes (vooral bij verlengd QTc-interval en tevens hypokaliëmie), compleet AV-block, ventriculaire tachycardie en premature ventriculaire contracties kunnen voorkomen. Bij snelle infusie kan hypotensie optreden. Bij hoge doses kunnen ventrikelfibrilleren en asystolie optreden. Soms maagdarmstoornissen, bittere smaak, duizeligheid, blozen, spierzwakte, depressie, psychose met hallucinaties, vergrote lever met stijging van de transaminasewaarden en overgevoeligheidsreacties, zoals urticaria, jeuk, maculopapuleuze uitslag, angio-oedeem en stijging van de antinucleaire antistoffentiter. Dit laatste kan gepaard gaan met systemische lupus erythematodes. Bloedbeeldafwijkingen, zoals agranulocytose, hemolytische anemie, trombocytopenie, leukopenie en neutropenie zijn bij 0.5% van de patiënten gemeld en treden meestal gedurende de eerste 3 maanden van de behandeling op. Bij het optreden van bloedbeeldafwijkingen dient de therapie te worden gestaakt. Bij aritmieën ten gevolge van digitalisintoxicatie kan additionele vertraging van de geleiding optreden, hetgeen kan leiden tot ventriculaire asystolie of ventrikelfibrilleren. Bij myasthenia gravis kunnen de symptomen verergeren.
