Panic anxiety after abrupt discontinuation of mianserin.
We observed a case of withdrawal after abrupt discontinuation of mianserin. A 41-year-old woman was treated according to a diagnosis of depression, which was her 6th episode. Mianserin 30 mg/day, etizolam 1 mg/day and flunitrazepam 1 mg/day were administered. When the patient discontinued taking the drugs by herself because of subsiding of these symptoms, severe panic anxiety appeared. This panic anxiety was not relieved by taking etizolam and flunitrazepam again, but subsided rapidly by the re-administration of mianserin 30 mg/day, and because of that the depressive symptom also disappeared. From these experiences panic anxiety seemed to be a withdrawal symptom, and involvement of the noradrenergic system in panic anxiety as well as serotonergic system was suggested.
