Antipsychotic-induced hyperprolactinaemia in women: pathophysiology, severity and consequences. Selective literature
1Manchester Mental Health and Social Care Trust, Manchester, UK. angelika.wieck@man.ac.uk
Background:
Hyperprolactinaemia has for decades been an inevitable and neglected side-effect of antipsychotic medication. The recent introduction of prolactin-sparing antipsychotic agents makes a re-examination of this problem timely.
Aims:
To review the literature on antipsychotic-induced hyperprolactinaemia and its consequences.
Method:
A search was made of the Medline database (1966-2002) for key articles, supplemented by cross-referencing.
Results:
During antipsychotic treatment prolactin concentrations can rise to ten times normal levels or above, and existing data indicate that 17-78% of female patients have amenorrhoea with or without galactorrhoea. Survey data, however, suggest that clinicians underestimate the prevalence of these conditions. Long-term consequences of antipsychotic-related hypo-oestrogenism require further research but are likely to include premature bone loss.
Conclusions:
Antipsychotic-induced hyperprolactinaemia should become a focus of interest in the drug treatment of psychiatric patients.
