These will include cases that involve recently marketed drugs for which there is limited knowledge of adverse effects and cases that highlight unusual reactions to drugs that have been marketed for several years.Sexual side-effects are common among those using antipsychotic medication and may result in poor compliance and reduced quality of life. Retrograde ejaculation (RE) has been described occurring with a number of antipsychotic medications (thioridazine, risperidone, iloperidone and clozapine) but there are no guidelines regarding management of antipsychotic-associated RE. Imipramine has been suggested as a treatment for antipsychotic-associated RE in one small study of patients prescribed thioridazine and a case series of patients prescribed iloperidone. Quetiapine is a commonly used antipsychotic and is thought to be associated with less sexual side-effects relative to other antipsychotic medications. This case report describes a 25-year-old man with first episode psychosis who developed RE during treatment with quetiapine which improved with low-dose imipramine. This is the first description of RE occurring with quetiapine and successful treatment of quetiapine-associated RE with imipramine.Quetiapine is a commonly used atypical antipsychotic medication.1 It is a dopamine D1 and D2, 5-HT2, alpha1-adrenoceptor and histamine-1 receptor antagonist and is licensed in the UK for the treatment of schizophrenia and bipolar affective disorder and as an adjunctive treatment in depression.2 Retrograde ejaculation (RE), where ejaculate passes into the bladder as oppose to down the urethra, occurs secondary to failure of contraction of the bladder neck. Causes of this include mechanical, for example, surgery, disruption of sympathetic innervation, such as diabetes or pharmacologic (eg, alpha1 antagonism).3 4 RE has been reported to occur with antipsychotic medications including … ER -
