Symptoms of overdosage with amlodipine include severe dizziness, fast, irregular or very slow heartbeat and confusion.
A study effecting intentional overdose with amlodipine showed that Amlokard produced prolonged hemodynamic effects which may lead to pulmonary edema. Patients with amlodipine overdose are recommended to be given aggressive decontamination therapy, considering the long elimination t½ and delayed onset of effects of Amlokard. Extended clinical monitoring and supportive care may be required if patients are hemodynamically unstable.
