Women should not take abortifacient drugs, the Irish Medicines Board (IMB) has warned.

More than 250 abortion pills have been seized since the beginning of the year. Abortifacients are not legally available here and it is not legal for anyone to supply or receive such medicines through an online source, the Irish Times reports.

A spokeswoman for the IMB said that the Board, in conjunction with the Revenue’s Customs Service and An Garda Síochána, monitors and investigates instances of the illegal supply of such products via the internet, “and actively enforces against suspected breaches of the law”.

Misoprostol and mifepristone are the most common abortion-inducing drugs. A total of 259 tablets have been detained in 10 consignments since the start of 2013. Of these, 256 contained misoprostol and three mifepristone.

Last year, 487 abortifacient tablets were seized, of which 471 contained misoprostol and 16 mifepristone, from 25 detentions.

A total of 635 tablets were seized in 2011 from 28 detentions. In 2010, 671 pills were detained in 40 consignments while the figure for the previous year was 1,216 tablets from 62 detentions.

The spokeswoman said when a package containing an abortifacient or other prescription-only medicinal product was detained on importation, the board made contact with the consignee to advise on the medicinal status of the product and of the legal position regarding supply.

“The IMB strongly recommends that a woman should not seek to obtain or self-medicate with such potent medicines. Any woman experiencing anxiety regarding a pregnancy should consult with her doctor or contact the crisis pregnancy programme of the HSE,” she said.

The IMB has also worked with agencies in other countries in a bid to stop or curtail such illegal supplies, she added.

Trade in the illegal pills is growing, and customs officials have seized more than 1,800 pills in recent years.
