The study

The palmitoylethanolamide (300 mg) was taken when the pain started, and a second dose was permitted if pain persisted after 2 hours. If the pain persisted after 4 hours, rescue medication (e.g., acetaminophen) was permitted, but if it was taken within 4 hours of pain onset, the data were excluded.

Palmitoylethanolamide reduced the reported menstrual pain at 1, 1.5, and 2 hours after treatment, compared with a placebo. For half of the menstrual pain episodes that required a second palmitoylethanolamide dose, the decrease in pain continued at 2.5 hours. At 3 hours after taking the supplement, there were no differences between the groups, likely due to the natural progression of menstrual pain relief over time.

There were no differences in rescue medication use or adverse events.
