What is the recommended evaluation and treatment for elevated serum prolactin?

History and physical examination can distinguish among most physiologic, pharmacologic, or pathologic causes of an elevated serum prolactin level (SPL) (strength of recommendation [SOR]: C, expert opinion). Patients with unexplained elevations of serum prolactin or with a level above 200 ng/mL should undergo imaging of the sella turcica (SOR: C, expert opinion). Mildly elevated SPL due to physiologic causes may be managed expectantly (SOR: B, cohort studies) and pharmacologic elevations may be treated by discontinuing the causative medication (SOR: C, expert opinion). Elevated SPL due to pathologic causes requires both monitoring for complications and treatment of the underlying condition (SOR: C, expert opinion)
