Symptoms and signs: There is limited experience of ONDAVELL overdose. In the majority of cases symptoms were similar to those already reported in patients receiving recommended doses.
Treatment: There is no specific antidote for ONDAVELL therefore in cases of suspected overdose ONDAVELL, supportive therapy and symptomatic should be given as appropriate.
The use of ipecacuanha to treat overdose with ONDAVELL is not recommended as patients are unlikely to respond due to the anti-emetic action of ondansetron itself.
