Medical Management of Miscarriage (Complete Guide)

What is medical management?

Medical management of miscarriage uses medication to help your body pass the pregnancy tissue, rather than waiting for it to happen naturally or having surgery. In the UK, the main drug used is misoprostol, a prostaglandin that softens the cervix and stimulates the womb to contract. It is usually offered when expectant management has not completed the miscarriage, or when a woman would prefer a more predictable timeline than waiting naturally.

How it is given

Misoprostol can be given in different ways. Most commonly it is inserted into the vagina, or sometimes taken as a tablet under the tongue (sublingually). You may be given one dose or a repeat dose after a few hours if the first has not worked. Some units also use mifepristone beforehand, though this is less common for miscarriage management in the NHS.

You will usually be given the medication in the early pregnancy unit and then go home to pass the miscarriage in a familiar, private setting. Some women prefer to stay in hospital, particularly if they live far from the unit or have had complications before.

What to expect

Within a few hours of taking misoprostol you will usually begin to feel cramping and see bleeding. The pain can be stronger than a normal period but should be manageable with paracetamol or ibuprofen. You will pass blood clots and possibly tissue. The heaviest part usually lasts a few hours, with lighter bleeding continuing for up to two weeks.

It is a good idea to have someone with you, plenty of maternity pads, a hot water bottle and comfortable clothing. Some women feel nauseous, shivery or develop a slight temperature after misoprostol. This is common and usually passes quickly, but a high fever may indicate infection and needs urgent review.

Success rates and follow-up

Medical management is successful in roughly 80 to 90 percent of first-trimester miscarriages. If an ultrasound scan after about seven to fourteen days shows tissue remains, you may be offered a second dose of misoprostol or surgical management.

Your EPU will arrange this follow-up scan either in person or, in some NHS trusts, through a self-administered swab or symptom check. Always ask for clarity on the plan so you know when and how you will be reviewed.

Side effects and risks

Common side effects include nausea, diarrhoea, shivering and cramping. More serious but rare risks include heavy bleeding requiring transfusion or surgery, and infection. Contact your EPU or A&E immediately if you soak a pad in under an hour, have severe pain, a high temperature or feel faint.

Emotional wellbeing

As with any miscarriage, the emotional impact can be significant. The Miscarriage Association offers excellent UK-based support, and your GP can refer you for counselling if needed. Remember that having a miscarriage does not mean you cannot go on to have a healthy pregnancy.
