Over-the-counter pain relievers such as ibuprofen, naproxen, or acetaminophen may help ease mild PMS symptoms (e.g., cramps, headaches, breast tenderness). When symptoms of PMS are severe, selective serotonin reuptake inhibitors (SSRIs) such as paroxetine (Paxil), fluoxetine (Prozac), citalopram (Celexa), or sertraline (Zoloft) can be tried. Oral contraceptives have also shown some benefit for reducing PMS symptoms. Theoretically, these work by regulating fluctuations of estrogen and progesterone throughout a cycle.[1]
