Atypical antipsychotic-induced hyperprolactinemia can cause important clinical symptoms, particularly in
young women and also in men, such as impotence, loss of libido, gynecomastia, anovulation and galactorrhea.
Methods: Observational over one-year follow-up of six patients (four women and two men, mean age of 31.1 years, range
26-37), treated with different atypical antipsychotics in an outpatient psychiatric device, who had clinical complications
associated to high prolactin serum levels. All of them were treated with standard doses of cabergoline.
Results: Most patients experienced significant clinical improvement after treatment with standard doses of cabergoline
(mean dosage 1.08 mg/week), maintained for a mean of 18 month. Normal prolactin levels were achieved after the first
months of treatment with cabergoline. No side effects or worsening of psychotic or behavioral symptoms were observed.
Conclusions: Long-term treatment with cabergoline seems to be safe in atypical antipsychotic-treated patients.
