Symptoms: Overdose of acetylcysteine has been reported to be associated with effects similar to the 'anaphylactoid' reactions noted in Adverse Reactions, but they may be more severe.
Treatment: Overdose treatment is based on immediate discontinuation of the infusion administration and symptomatic treatment and resuscitation. There are no specific antidotal treatments; acetylcysteine is dialyzable.
Paediatric population: The same symptoms and treatment apply to the paediatric population.
