Safety of cabergoline in the management of pituitary prolactin-induced symptoms with patients treated with atypical neuroleptics.

UNLABELLED: 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.
