title: Rapid normalization of the dexamethasone suppression test with mianserin.
abstract: Dexamethasone suppression tests (DSTs) were carried out in 6 depressed patients and 2 with schizophrenia before and 48 to 72 hours after starting treatment. All 8 were non-suppressors before treatment but the 5 patients treated with mianserin and 1 treated with chlorpromazine had normal suppression with the repeat DST, unrelated to clinical change. Non-suppression persisted in the 2 patients treated with ECT or haloperidol. Mianserin and chlorpromazine could, therefore, be associated with false negative DST results. Possible mechanisms for this are discussed.
