Abstract

Background: Hyperprolactinaemia among patients on antipsychotic medications is generally overlooked due to lack of outwardly visible  symptoms, patient resistance to reporting because the symptoms are perceived as shameful, or to clinician’s insufficient knowledge.    


Aim: The study aimed to evaluate the patterns and correlates of hyperprolactinemia among patients with schizophrenia on antipsychotic  medications. 


Setting: The study was conducted in a psychiatric facility in Maiduguri, Northeastern Nigeria.


Methods: A total of 209  patients with schizophrenia were evaluated through a cross-sectional design and assayed for serum prolactin with ELISA Kits.  Frequencies and percentages were tabulated for categorical variables. Variables with significant associations with hyperprolactinaemia  on chi-square (p < 0.05) were subjected to logistic regression analysis.


Results: The prevalence of hyperprolactinaemia was 45.9% in all  patients on antipsychotic medication. The prevalence because of the use of typical and atypical antipsychotics was 51.5% and 25.0%,  respectively. Hyperprolactinaemia was significantly associated with typical antipsychotics (β = 0314, p = 0.002), high overall drug dosage  (β = 2.340, p = 0.003), high-dose typical antipsychotics (β = 3.228, p = 0.000), twice daily dosing frequency (β = 2.751, p = 0.001) and  polypharmacy (β = 1.828, p = 0.0024).


Conclusion: The findings support that patients on typical, high-dose antipsychotic medications and  polypharmacy have a high prevalence of hyperprolactinaemia. As hyperprolactinaemia is often undetectable, screening and patient  psycho-education on the significance of the signs and symptoms of hyperprolactinaemia is required for necessary clinical intervention.  


Contribution: The study provides evidence for the rational use of antipsychotic medications in sub-Saharan Africa
