Less than a year after losing her daughter Emilia at five days old, Jillian Phillips suffered a miscarriage.

It was Halloween weekend in 2016, and her doctor said she could wait for it to end naturally, have a surgical procedure or take medication. She chose the medicine, passed the remains of her nine-week pregnancy at home and buried them in a memorial garden, near some of Emilia鈥檚 ashes.

鈥淥nce I found out that the baby inside me was no longer viable, I didn鈥檛 want to just walk around carrying the emotional trauma of that,鈥 said Phillips, a 41-year-old single mother of three from North Brookfield, Mass. 鈥淵ou just kind of want it finished. And the medication works pretty quickly.鈥

But the future of this common miscarriage treatment is in peril. The pill, mifepristone, is used in abortions, making it a target.

Last month, a to block mifepristone's approval by the Food and Drug Administration. The Supreme Court later to the drug while the lawsuit winds through the courts, a long road that continues with arguments before an appeals court on May 17.

Doctors and patients fear mifepristone could be pulled off the market when the legal wrangling ends. Already, they say, a chilling effect keeps some doctors from prescribing it.

A million U.S. women a year suffer miscarriages, which occur in at least 15% of known pregnancies. Mifepristone was approved in 2000 for early abortions but it is often used 鈥渙ff label鈥 to treat early pregnancy loss or to speed up delivery when a fetus dies later in pregnancy. These uses are so common that to apply to the FDA to add miscarriage to the label of its drug, Mifeprex.

Denise Harle, an attorney for the group that filed the Texas lawsuit on behalf of anti-abortion doctors and health care organizations, said they aren't challenging uses of the drug beyond abortion. But legal experts say if it鈥檚 taken off the market for its approved use, it wouldn鈥檛 be available for pregnancy loss.

Dr. Kristyn Brandi said that would take away 鈥渢he gold standard of miscarriage management," the two-drug combination of mifepristone and misoprostol that helps empty the uterus and reduce the chance of infection.

鈥淚 offer it to every single patient whose miscarriage I manage,鈥 said Brandi, an OB-GYN in Newark, New Jersey. 鈥淭here will be a big impact if I am no longer able to use that medication.鈥

HELP THROUGH THE PAIN

Brandi said medication speeds up the miscarriage process at a time when women are already suffering physically and emotionally.

Most patients naturally pass pregnancy tissue within two weeks of their diagnosis, but it can take several weeks, according to the American College of Obstetricians and Gynecologists. Tissue generally passes within 48 hours when women take the medication, which studies show is about 80%-90% effective.

Brandi gives mifepristone to patients in her office. It blocks the hormone progesterone and primes the uterus to respond to the contraction-causing effect of misoprostol, which is taken later at home.

Phillips, a social worker, said the medicine made a horrible situation a little more bearable.

At her second ultrasound, doctors couldn鈥檛 detect cardiac activity in the fetus. Phillips considered getting a 鈥渄ilation and curettage鈥 procedure, but didn't like that she would need general anesthesia and couldn't take the remains home. Medication seemed a better option.

She took mifepristone and wound up needing two doses of misoprostol. 鈥淏ut the miscarriage itself was not really any more significant than my worst periods,鈥 she said. 鈥淎nd I was in the comfort of my home with my family.鈥

Today, she finds solace in her memorial garden, where small angel figurines are arranged near a tree in her front yard.

Myriad Norris, 25, of Lexington, Kentucky, said she was glad mifepristone was available when she had a miscarriage in late March 鈥 even though she ended up not needing it.

About 12 hours after discovering she was pregnant, Norris started cramping, then bleeding. Worried she could develop an infection, she asked her doctor about mifepristone. She was just over five weeks pregnant, and the tissue passed on its own.

Soon news broke about the Texas judge's ruling. Norris, a stay-at-home mom who is active in the group Kentucky for Reproductive Freedom, said it brought 鈥渁n additional layer of grief.鈥

鈥楥HILLING EFFECT鈥 AND BACKUP PLANS

Mifepristone has long been subject to special restrictions, though experts say it鈥檚 as safe as the over-the-counter painkiller ibuprofen. For example, the FDA requires it to be dispensed by, or under the supervision of, a certified prescriber.

Doctors say the current legal climate is tightening access further.

鈥淚t鈥檚 kind of creating this chilling effect" where even though it's still approved and available, doctors "aren鈥檛 going to give it because they鈥檙e too worried about whatever ramifications are coming afterward,鈥 Brandi said.

Dr. Sarah Prager, an OB-GYN at the University of Washington School of Medicine, said her health system doesn鈥檛 restrict mifepristone, but others in her state do.

鈥淔acilities that don鈥檛 want to have anything to do with abortion have chosen not to carry mifepristone on site,鈥 she said. That includes Catholic facilities, which house a growing percentage of acute care hospital beds.

As doctors wait to learn mifepristone's fate, they're making backup plans for miscarriage care.

One involves using only misoprostol to manage miscarriages. While it鈥檚 safe, research shows it鈥檚 not as effective at helping expel pregnancy tissue 鈥 which can lead to a dangerous infection if it stays in the uterus. The treatment success rate for miscarriage patients who got misoprostol only was 67%, compared with 84% for those who took the two drugs, a in the New England Journal of Medicine found.

That means misoprostol-only patients are more likely to need a follow-up surgical procedure or additional doses. It also leads to "significantly more discomfort,鈥 Prager said.

鈥淚t really feels like we鈥檙e just punishing people by not being able to give them an evidence-based and least-impactful regimen of medication,鈥 she said.

Phillips said patients deserve all the options she had.

During a miscarriage, 鈥測ou already feel completely traumatized and devastated,鈥 Phillips said. 鈥淚t鈥檚 frightening to think that people may be in the same situation that I was and would not be able to get appropriate health care.鈥
