Selective serotonin reuptake inhibitors (SSRIs) are widely used in the treatment of 
many types of mental disorders. Citalopram is commonly used as a new generation 
of SSRIs in this regard; however, unfortunately, its overdose is associated with 
seizure and heart disorders. The reported case in the present study indicated 
recurrent seizures, nonspecific ST-T changes, and prolonged QT interval due to 
the overuse of citalopram. The patient had bilateral anterior shoulder dislocation 
along with right proximal humerus fracture that was occurred during the seizure. 
The dislocation was initially reduced and then fixed. Moreover, the seizure was 
controlled with diazepam without any problems, and cardiac monitoring continued 
for 2 days. Massive citalopram overdose may be associated with recurrent seizures 
and QT prolongation. Complications postseizures, such as shoulder dislocations, 
should be examined for and managed appropriately.
