Identify a common first-line treatment for premenstrual syndrome (PMS).

Selective serotonin reuptake inhibitors (SSRIs) are commonly recognized as a first-line treatment for premenstrual syndrome (PMS). They are effective in alleviating mood-related symptoms such as irritability, depression, and anxiety that can accompany PMS. SSRIs work by increasing the levels of serotonin in the brain, which can help stabilize mood and improve overall psychological well-being.

While other treatments like oral contraceptives can also be beneficial for managing PMS symptoms, especially in individuals with significant menstrual-related discomfort, SSRIs specifically target the emotional and psychological symptoms often associated with PMS. The use of NSAIDs can address physical symptoms, such as cramping and body aches, but they do not directly address the psychological aspects of PMS. Natural supplements may offer some relief for some individuals, but they are generally not as well-studied or established as SSRI therapy. This makes SSRIs a more widely accepted first-line option in clinical practice for managing the emotional symptoms of premenstrual syndrome.
