OBJECTIVE: We examined the relationships between long-term treatment response, side-effects and drug discontinuation in panic disorder (PD)-agoraphobia. METHOD: A total of 326 patients were naturalistically treated with antidepressants and followed for a period of 3 years. All patients were evaluated by means of the Panic Disorder/Agoraphobia Interview and the Longitudinal Interview Follow-up Examination (LIFE-UP). RESULTS: A total of 179 patients interrupted pharmacological treatment. Among them, 26.8% were not traceable; 36.9% had deemed further contact with the psychiatrist unnecessary because of remission. Other reasons for interruption were: ineffectiveness (18.4%), side-effects (10.6%) and personal reasons (7.3%). Patients who interrupted pharmacological treatment because of symptom remission remained in the study for a longer period than those patients who interrupted their treatment because of inefficacy. CONCLUSION: In the long-term treatment of PD with antidepressants, a high percentage of patients who have achieved symptom remission tend to default from further treatment; adherence to long-term treatment with antidepressants was predicted by severe and long-lasting symptomatology.
