Sadhana Ahmed has written ten dramas for the stage. In addition, she wrote about twenty-five scripts for the television. She also directed some of her writings.

In her writing, she tries to portray the reality of life and contemporary socio-political and socio-economical context through diverse characters where the immediate material reality and the truth of life differ from person to person. They are not the same in societies across the world. The differences are responsible for diverse cultures and patterns. In her writing, she tries to identify the conflicting reality of human life by creating and developing different characters. At the same time, she tries to capture the philosophy behind the social-political structure to portray the handful of power-hungry people on the one hand and the oppressed majority who are living in the rural hinterland of this river delta.

Most of her characters are born in Bangladesh within a highly multicultural Indian background. While developing the characters, she tries to make it so that the struggle and resistance of the local people gradually transformed into a fight and resistance of every human being. Sadhana also wants to show that personal problems are part and parcel of social problems when she tells the story through the love story by the language of silence. Religion, politics, philosophy, rituals, social mind of people, including how they appear in a multicultural condition, is a critical focus in her plays. Sadhana writes in Bangla Narrative form, but she has made a distinguished style of writing language and expression for herself.
