Q. What is the treatment for PMDD?

A. 

"Based on all of the scientific evidence, the first-line conservative treatment for PMDD are SSRIs (selective serotonin reuptake inhibitors, for example: sertraline)— about 60% of women with PMDD benefit from SSRIs. Although SSRIs are thought to take a while to “kick in” in depression or anxiety, SSRIs seem to work faster in PMDD (working better than a sugar pill after about a day!). This leads many experts to believe that they are working through a different pathway to reduce PMDD. Because they work so quickly in PMDD, SSRIs can be taken only in the luteal phase, between ovulation and menses—or, they can be taken the whole month long. SSRIs seem to help the most with emotional PMDD symptoms, and less with physical symptoms.

The second conservative treatment is drospirenone-containing oral contraceptive pills (DCOCs) that contain estrogen (.02 mg of ethinyl estradiol) plus a new progestin (3mg drospirenone), taken on a 24-4 schedule (24 active pills, 4 inactive pills). The brand name for this pill is “Yaz”, but generic versions contain the same hormones. Some studies show that DCOCs can help PMDD, but they don’t help emotional symptoms as much as SSRIs do. Some studies show that DCOCs seem to work especially well for physical PMDD symptoms.

If neither SSRIs nor DCOCs have been effective for PMDD after a few cycles, and the cyclical symptoms are severe, a doctor can prescribe other, more intensive treatments to suppress the cyclical hormone changes that are known to trigger PMDD. Some doctors use estrogen patches (transdermal estradiol) with short intermittent courses of (oral micronized) progesterone pills to prevent ovulation and therefore suppress hormone cycling. However, the more typical and best-studied cycle suppression method is an injection of something called a GnRH agonist (there are several of these, but the most-used example is called leuprolide), which shut down hormone production by the ovaries, causing a reversible menopause in which your hormone levels stay very low and flat. However, because female bodies need some hormones to stay healthy, the doctor will need to prescribe estrogen (and intermittent short doses of progesterone) in order to keep your bones and reproductive system healthy. The bad news is that, during the first month of this hormone addback on top of the GnRH agonist, you may experience your PMDD symptoms again. The good news is that a recent study has found that this hormone addback-triggered “PMDD” only lasts about a month, after which the brain is able to recover from the surge of hormones and the symptoms go away despite the same levels of stable hormones.

If the GnRH agonist plus hormone addback (often called a “menopause trial”) goes well, many women will choose to have a total hysterectomy with bilateral oopherectomy (removal of the uterus and both ovaries) to once-and-for-all remove the hormonal flux that causes symptoms. Bilateral oopherectomy (removal of the ovaries) eliminates hormone cycling, and usually eliminates cyclical symptoms in women with PMDD. Removal of the ovaries is the critical piece of this treatment—if either ovary remains in your body, so will your PMDD. Both ovaries must be removed for this surgical treatment to be effective. Addback of transdermal estrogen is also usually necessary during surgical menopause, and should be introduced gradually to reduce the risk of PMDD symptoms returning."
