The storyline of domestic violence between characters Suzanne Halpin and husband Damien has touched a nerve with many men who are suffering similar attacks at home.
The shocking scenes aired on the series have resulted in a rise in calls to national helpline and support service Amen.
According to the support service, the number of callers has increased dramatically as a result of the Fair City plot.
"Many factors have attributed to this, and Fair City is one of them," said Niamh Farrell, manager of Amen.
The show featured Suzanne Halpin, played by Sarah Flood, beating her husband Damien for cheating on her.
Viewers have seen Suzanne engage in abusive outbursts and acts of physical violence towards Damien -- played by Maclean Burke.
RTE said the storyline was in the making over an 18-month period and involved extensive liaison with and support from key bodies in the area.
