Premenstrual Syndrome - Highlights

Highlights

Oral Contraceptives

• A new type of low-dose oral contraceptive may help improve the symptoms of premenstrual dysmorphic disorder (PMDD), according to research published in Obstetrics and Gynecology. PMDD is characterized by severe mood swings and includes depression, irritability, and anxiety. The new oral contraceptive called Yaz combines an estrogen (estradiol) with a new type of progestin called drospirenone. The FDA is currently reviewing the drug.

Antidepressants

• Taking the antidepressant paroxetine (Paxil) for just two weeks before menstruation (“intermittent dosing”) can help prevent mood disorders associated with PMS, according to a 2005 study published in the American Journal of Obstetrics and Gynecology. Earlier studies indicated that paroxetine helps control PMDD when patients take it on a continuous basis. Intermittent dosing is also known as luteal phase dosing. The luteal phase is the time between ovulation and menstruation. PMS symptoms tend to occur during the last week of this phase.

Diet

• Skim milk and low-fat yogurt might help ward off PMS. A study published in the Archives of Internal Medicine reported that calcium and vitamin D, found in dairy products, may help prevent PMS symptoms. Researchers studied the diets of over 3000 women. Women whose diets were highest in calcium (about 1200 mg/day) and vitamin D (about 400 IUD/day) had the lowest risk of developing PMS. Supplements may also help prevent PMS, but food sources provide the most nutritional value.
