Mone said she left the store in tears.
"Last night I experienced something no woman should ever have to go thru [sic]", posted Arteaga, a teacher. Unfortunately on Tuesday we found out the baby's development had stopped and I ultimately will have a miscarriage.
"Each week I went for my ultrasound praying to see progress and hear the sound of little heartbeat". In the case of a fetus failing to develop, it is performed to prevent infection or heavy bleeding.
"We are looking into the matter to ensure that our patients' needs are handled properly", the statement said.
It said it had "reached out to the patient and apologised for how the situation was handled".
As devastating as Mone's experience is, it is not illegal for pharmacists in Arizona to deny filling a person's prescription if it conflicts with their moral or ethical beliefs.
Arteago said she left Walgreens without her prescription. "You get that excitement and then things like this happen and I don't have control over it. This is something I have zero control over". And I wanted this baby.
"I will not tolerate the possibility of one of us, or my children, being denied life-saving medication because some pharmacist with less education than I makes a personal moral call about the medication our DOCTORS feel is warranted".
Ms Mone wrote the pharmacist had "no idea" what it was like to want to deliver a child but be unable to do so.
As for the pharmacist, she has this message: "Just have compassion for people because you don't know what they're going through", said Arteaga.
Mone says she has contacted the store manager, the Walgreens corporate office and has filed a complaint with the Arizona Board of Pharmacy. "What I have inside of me is an undeveloped baby", she recalled telling the pharmacist. At this time I have done what I can to report the situation.
"You have a right to step away, but you don't have a right to step between" patients and their access to legal and medically appropriate treatment options, she added.
Ms. Arteaga described her response in the post, which has been shared more than 30,000 times.
Arteaga was offered a choice between taking prescribed medication to induce a miscarriage or undergoing a hospital procedure. So, she took her 7-year-old with her to her local Walgreens to pick up the medication-and her pharmacist wouldn't give it to her.
But it is within the store's guidelines for pharmacists to refuse service "for which they have a moral objection". "At the same time, they are also required to refer the prescription to another pharmacist or manager on duty to meet the patient's needs in a timely manner".
"A pharmacy, hospital or health professional, or any employee of a pharmacy, hospital or health professional, who states in writing an objection to abortion, abortion medication, emergency contraception or any medication or device meant to inhibit or prevent implantation of a fertilized ovum on moral or religious grounds is not required to facilitate or participate in the provision of an abortion, abortion medication, emergency contraception or any medication or device meant to inhibit or prevent implantation of a fertilized ovum".
Under state law, Arizona pharmacies must require employees to notify them of drugs they would decline to fill because of "sincerely held religious beliefs".
