Quinagolide — Uses, Dosage, Side Effects & Safety

Drug class: Dopamine agonist (prolactin inhibitor)

Overview

Quinagolide is a medication used to treat high levels of the hormone prolactin, a condition known as hyperprolactinemia. This can result from pituitary tumors (prolactinomas) or other causes and may lead to symptoms such as irregular menstrual periods, infertility, or unwanted breast milk production in both women and men. Quinagolide works by mimicking the action of dopamine, a natural chemical in the brain that helps control the release of prolactin from the pituitary gland. By lowering prolactin levels, it helps restore normal menstrual cycles, fertility, and reduces symptoms related to excess prolactin. Patients should know that Quinagolide is usually taken once daily, preferably in the evening. It is important to follow your healthcare provider’s instructions closely and report any unusual symptoms, especially if you experience severe headaches, vision changes, or signs of low blood pressure.
