There are concerns about women who access abortion pills online. An organisation called 'Women On Web' is using college notice boards and lampposts to advertise a drug that induces miscarriage.
After an online consultation, the pills are sent to addresses in the north to evade detection.
'Women on Web' say they are an international collective that answer questions from women around the world.
The website lists their postal address as Amsterdam in The Netherlands.
However, health groups here are warning that those who order the pills online have no guarantee they are safe or effective.
The medical director of the Well Woman Clinic in Dublin is Dr Shirley McQuaid.
She is advising people who have side effects from the drug to seek medical assistance.
