## **Core Concept**
The patient's symptoms of amenorrhea, infertility, and galactorrhea suggest hyperprolactinemia, a condition characterized by elevated levels of prolactin in the blood. This condition can disrupt normal menstrual function and fertility. The treatment often involves medications that decrease prolactin secretion.

## **Why the Correct Answer is Right**
The correct answer, **C. Cabergoline**, is a dopamine agonist that inhibits the secretion of prolactin from the pituitary gland. It is commonly used to treat hyperprolactinemia and its symptoms, such as amenorrhea, infertility, and galactorrhea. Cabergoline works by stimulating dopamine receptors in the pituitary gland, which decreases prolactin secretion. It is administered orally and has a higher efficacy and tolerability compared to other dopamine agonists like bromocriptine. The careful questioning about previous mental health problems is relevant because dopamine agonists can have psychiatric side effects.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that when using dopamine agonists like cabergoline, it's crucial to monitor patients for potential side effects, including psychiatric manifestations such as depression, anxiety, and hallucinations. The patient's history of mental health issues is important because these drugs can exacerbate or trigger psychiatric conditions.

## **Correct Answer:** C. Cabergoline
