Five Things to Know About the Morning-After Pill on Its 20th Anniversary

In 1993, the New York Times Magazine posited that the morning-after pill might be “the best-kept contraceptive secret in America.” Even many doctors had no idea there was a fallback contraceptive that could be used shortly after unprotected sex or cases of rape.

In many ways, the morning-after pill had been right in front of U.S. doctors for decades. In terms of chemical composition, it was not much different from standard birth control, using the same main ingredients — synthetic hormones — in higher doses. Moreover, many of their colleagues in Europe and Asia had already been prescribing morning-after pills for years.


In 1998, years of research and advocacy led to the first FDA-approved morning-after pill.


Here, however, the secret was still largely intact. A 1994 study by the Kaiser Family Foundation revealed that two-thirds of American women had never heard of the morning-after pill or other forms of emergency contraception (EC). Less than 1 percent had ever used them.

There was an information shortfall in large part because there was no contraceptive that was approved by the U.S. Food and Drug Administration (FDA) specifically for emergency use. Some providers worked around that absence by using the chemically similar estrogen and progestin medications that were approved for regular birth control. By upping the dosage, they created a suitable morning-after pill on their own. But drug makers couldn’t label or market those birth-control pills for emergency, post-coital use, since they weren’t FDA-approved for that purpose. It also spelled problems for federally funded clinics. Federal dollars couldn’t pay for an off-label medication hack, a makeshift morning-after pill that wasn’t officially approved. Continue reading

STD Awareness: The Curious Case of Chancroid

Earlier this year, I asked a room full of scientists and medical professionals to raise their hands if they’d ever heard of chancroid. Everyone sat there, motionless, confused by the odd syllables I had uttered — shan kroyd. If you’ve never heard of chancroid, you’re not alone.

Chancroid is a sexually transmitted disease (STD) brought to you by Haemophilus ducreyi, a type of bacteria that can pass through microscopic tears in the skin during sexual contact. When one partner is infected, there is a 1 in 3 chance the other will become infected. An infection can cause painful sores and swollen lymph nodes, most often in the genital region. About half of people with chancroid infections will experience “buboes,” or swollen lymph glands that might rupture. Before it could be cured with antibiotics, a persistent infection could cause permanent skin damage.


Humanity can make chancroid the first STD to go extinct.


One reason you probably haven’t heard of chancroid is that, in the developed world at least, it has mostly disappeared. In fact, researchers believe chancroid can be completely wiped off the planet — which would make it the first STD ever to be forced into extinction. How amazing would that be?

Chancroid has been hopping from loin to loin since at least the days of the ancient Greeks, and was common until the 20th century, when rates began to decline. Thanks to antibiotics, U.S. chancroid rates decreased 80-fold between 1947 and 1997, all but vanishing by the late 1950s. It was virtually unheard of until there was another spike in the 1980s, correlating with the crack epidemic. But, since 1987, cases have been steadily declining. Continue reading
