Paramedic Stephen Doohan assaulted and sexually assaulted the woman while administering the tablets at his home on two occasions in March 2023.
The 33-year-old, from Edinburgh, had researched the topic of abortion online after the woman told him she was pregnant.
While off-duty, Doohan checked for information about the drug on a work system just two days before he first gave it to the victim.
The woman later attended at a hospital with the accused and was told she was having a miscarriage.
Doohan then sent the victim gifts including perfume, socks, facial cleansing oil, money to get her hair done and bought tickets for them to attend a football match.
He also referred to the victim not reporting him to the police before telling her his location for officers to come and arrest him.
Doohan pleaded guilty to two charges at the High Court in Glasgow on 16 May 2025.
On 7 July 2025, at the same court, Doohan was jailed for 10 years and six months.
His name has been added to the sex offenders register.
A non-harassment order, banning Doohan from contacting or attempting to contact the victim, was also granted for an indefinite period.
Fiona Kirkby, Procurator Fiscal for High Court Sexual Offences, said:
"Stephen Doohan's calculated and heinous actions caused the loss of the victim's pregnancy, robbing her of plans she had for the future.
"He has now been held accountable for this fundamental breach of trust.
"While offences like this are thankfully rare, I hope this prosecution sends a clear message to all those who seek to inflict sexual harm towards women.
"Our thoughts remain with the victim, who must be commended for reporting her experience and seeking justice.
"We recognise that reporting sexual offending can be difficult but would urge anyone affected to come forward and seek support when they feel ready to do so."
