Flying back to Ireland after your abortion

When you are ready to return home following treatment, one of our Marie Stopes UK nurses will give you some advice with regards to travelling home. You will also be provided with a leaflet which details precautionary measures to take if you are flying back to Ireland.

 Following your abortion treatment, we advise you to:

  • Mobilise frequently during the flight
  • Drink plenty of fluids but avoid alcohol and limit caffeine intake

These precautions are there to avoid the risk of blood clots also known as venous thromboembolism (VTE) which can occur during air travel.

Risk factors for VTE include:

  • Pregnancy
  • Recent surgery (particularly pelvic)
  • Prolonged immobility including air travel
  • Dehydration
  • Taking the combined oral contraceptive pill
  • General anaesthesia

Evidence suggests that the greater the distance travelled by air, the higher the risk of VTE. If you are particularly worried about this risk because of family history for example, please speak about this in more details with the nurse who will look after you when you receive treatment.

Specific consideration for travel after taking the abortion tablets

Managing bleeding and pain on your way back to Ireland

After a medical abortion – taking two sets of tablets - there is a risk that heavy bleeding might start before you get home to Ireland. If you have had a medical abortion, you may also experience discomfort for a number of hours following the administration of the second tablet.

We therefore recommend that you carefully think about how you will manage possible bleeding and pain during your flight home before you leave Marie Stopes UK. Please know that our team will make sure you receive the appropriate amount of analgesia before leaving the centre if you are travelling. They are also here to respond to any queries you might have before or after your abortion so don’t hesitate to ask or contact our aftercare line. 

Passing the pregnancy on your flight home

Following a medical abortion, you may pass the pregnancy at anytime from taking the second set of tablets, however this is typically between 24 and 48hrs but can be up to 2 weeks after.

Side effects of medication: the medication you would have received for your abortion treatment may have unpleasant side effects which you might experience during your flight home. These include: nausea, diarrhoea and shivering.
