Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain as well as fever. Naproxen relieves common pain symptoms of premenstrual syndrome (PMS), with the exception of breast pain. Naprosyn tablets are commonly given for menstrual cramps, headaches, and pelvic discomfort and reduce the severity of these symptoms in women with PMDD.

Naproxen tablets reduce heavy menstrual bleeding when compared with placebo but are less effective than some of the other medications used for menorrhagia such as tranexamic acid or danazol. In the limited number of studies available, NSAIDs did not differ significantly in effectiveness compared to other treatments. However, there have been some reports of fewer side effects with anti-inflammatory drugs.

Women who experience severe cramping may take naproxen 1 to 2 days before cramps begin. Naproxen improves physical symptoms and headache in women with PMS. Overall, Naprosyn may alleviate a wide range of symptoms except for breast pain.

Special information
Stop taking this drug (with doctor's approval) approximately 48 to 72 hours prior to surgical or dental procedures as it affects the body's ability to form blood clots and may increase bleeding time. In April 2005, the FDA announced the potential addition of a black box warning to the labeling of this class of drugs (NSAIDs), specifically regarding potential serious cardiac events and potentially life-threatening gastric adverse events.

In one study conducted in New Zealand, 45 ovulatory women with a complaint of menorrhagia were divided into three treatment groups. They received therapy with mefenamic acid in two cycles and one of three other agents in two cycles: naproxen, a low dose monophasic combined oral contraceptive, or low dose danazol. Mefenamic acid reduced measured blood loss by 20%; 38%; and 39% in groups one to three respectively. Naproxen reduced blood loss by 12%; the oral contraceptive by 43%; and danazol by 49%. There was no significant difference in blood loss reduction between any of the treatments, although women on danazol experienced a dramatic, highly significant further reduction in blood loss after the first treatment cycle.
