A new report suggests that men and women experience pain very differently from one another, and that doctors should consider these differences when prescribing pain medications. When researchers administered the same dosage of kappa opioids . a painkiller . to 28 men and 20 women who were having their wisdom teeth extracted, the women reported feeling much less pain than the men, and the easing of pain lasted considerably longer in women. This research suggests that kappa opioids should be prescribed for women whenever pain medication is required, whereas men should be given other kinds of pain medication. In addition, researchers should reevaluate the effects of all medications on men versus women.
