What precautions should I take when using a prolactin test?
Stress from trauma, illness, surgery, or even nervousness about a blood test can elevate prolactin levels. Drugs that may increase prolactin include phenothiazines, oral contraceptives, opiates, histamine antagonists, monoamine oxidase inhibitors (MAO inhibitors), estrogen, and antihistamines. Drugs that can decrease values include levodopa and dopamine. Source: The Gale Group. Gale Encyclopedia of Medicine, 3rd ed.
