A team led by Abigail Aiken at the University of Texas analysed the experiences of 1,000 women from the Republic and Northern Ireland who used the drugs distributed by the organisation, mifepristone and misoprostol, in early pregnancy.
"Organisations like Women on Web supply the same safe, high quality medications that women would receive if they came to BPAS.' She also said 'the greatest risk women face when using online pills is not a medical one, but a legal one", pointing out that taking the pills illegally carries a maximum sentence of life in jail.
Online telemedicine can offer a safe and effective way to end pregnancies in nations that restrict abortions, where many women to choose unsafe alternative methods.
78 per cent were under seven weeks pregnant, while the remaining 22 per cent were seven to nine weeks pregnant.

She added that the criminalisation of abortion puts women and pregnant people at risk. "It does not compare these women to another group of women who had medical abortions under medical supervision", he said.
For the study, researchers analyzed data from the group between 2010 and 2012, and found that during follow-up consultations, 95 percent of the participants reported having terminated their pregnancies without surgical intervention, the Post notes.
According to the academics, the results of the survey provide "the best world evidence to date" about the effectiveness of using an online service. Women can either travel long distances to access care in a clinic--if they have the requisite financial and social resources--or they can find a way to do their own abortion outside the clinic setting.
Potential legislation would require more rigorous reporting of medical complications related to an abortion and a ban on medical research on fetal tissue from abortions.
"The Adverse Events Report lists 2,207 reported cases of adverse events including 14 deaths, 612 hospitalizations, 58 ectopic pregnancies, 339 cases of blood loss requiring transfusions, and 256 cases of infections, of which 48 cases were considered severe", she said.
