The symptoms described - lack of emotion, indifference and problems with concentration often occur at the beginning of therapy, when the body adapts to the medication, and usually disappear within a few days. However, if symptoms persist longer or worsen, it is recommended to consult a doctor to assess the need for dose adjustment or to consider alternative treatment. It is important not to ignore these symptoms, especially if they affect your quality of life and daily functioning.
