How can I deal with PMS on my daughter?

Several Options. Pms is not unusal in young women. Symptoms vary from mild to severe, and are divided into physical symptoms as well as emotional ones. As for medications: ssris, birth control, certain diurtics, and a mutivitamin may help as needed. Additionally, increase in exercise, health diet and caffeine reduction may help. Have her keep a symptom/menstrual calender to see when she is most symptomatic.
