Drug-induced hyperprolactinemia.

Hyperprolactinemia is the most common biochemical abnormality currently encountered in clinical endocrinology. Hyperprolactinemic syndromes are a diverse group of disorders that are common in both men and women. Once the diagnosis of hyperprolactinemia has been established, the patient should be screened for the numerous causes of hormone hypersecretion. Hence, an accurate medical history is extremely important for the clinician to find out the most frequent causes of hypersecretion of prolactin (e.g., drugs). Clinicians should be aware of the possibility of prolactin elevation and associated problems with any drug that has the potential to cause hyperprolactinemia, particularly in patients who have other factors that might stimulate prolactin release.
