Medications

Nonsteroidal anti-inflammatory drugs (NSAIDs) block prostaglandins, substances that dilate blood vessels and cause inflammation. NSAIDs are usually the first drugs tried for almost any kind of minor pain. There are dozens of NSAIDs. Aspirin is the most common. Among the most effective NSAIDs for menstrual disorders are ibuprofen (Advil, Motrin, Midol PMS), naproxen (Aleve, Naprosyn, Naprelan, Anaprox), and mefenamic acid (Ponstel). Studies have also indicated that they are most helpful when started 7 days before menstruation and continued for 4 days into the cycle.

Acetaminophen

Acetaminophen (Tylenol) is a good alternative to NSAIDs, especially when stomach problems, ulcers, or allergic reactions prohibit their use. Products that combine acetaminophen with other drugs that reduce PMS symptoms are helpful. Brands include Pamprin and Premsyn. Such drugs typically also include a diuretic to reduce fluid and an antihistamine. Little evidence exists to indicate whether they are more or less effective than NSAIDs or other mild pain relievers.

Antidepressants

Selective Serotonin-Reuptake Inhibitors. Selective serotonin-reuptake inhibitors (SSRIs) are drugs that keep higher levels of serotonin available in the brain. They have become the most effective treatments for premenstrual dysphoric disorder (PMDD) and for severe PMS symptoms. Three SSRIs are currently approved by the FDA for the treatment of PMDD symptoms. They are fluoxetine (Prozac, Sarafem), sertraline (Zoloft), and paroxetine (Paxil). Other SSRIs such as fluvoxamine (Luvox) and citalopram (Celexa) are also being investigated for PMDD treatment.

SSRIs may help not only premenstrual dysphoric disorder but also premenstrual physical symptoms, irritability, and tension. SSRIs appear to work much faster for relieving PMS-related depression than when used in major depression. These drugs are typically prescribed with either continuous (daily) dosing throughout the month or an intermittent dosing regimen. With intermittent dosing, women take the antidepressant during the 14-day premenstrual period of their luteal phase. This approach is also associated with fewer adverse effects than the standard regimens for major depression.
