Today, we welcome the news that the National Institute for Health and Care Excellence (NICE) has recommended the use of progesterone to help prevent early miscarriage.
The new guidance comes after researchers at our National Centre for Miscarriage Research published findings from their clinical trial, PRISM, in 2019. This study looked at using progesterone – a natural hormone produced during pregnancy that helps prepare the body for a growing baby – as a treatment to prevent miscarriage.
One of the key findings showed how taking daily progesterone can help give those with early pregnancy bleeding and a history of miscarriage the best chance of carrying a baby to term.
PRISM studied 4,153 women who experienced early pregnancy bleeding at 48 hospitals in the UK. Of those, around half were given progesterone pessaries (400mg) to take until 16 weeks into their pregnancy, and the other half were given dummy tablets. The results found a 5% increase in the number of babies born to those given progesterone, who had previously had one or more miscarriages, compared to those given a placebo. The benefit was even greater for the women who had experienced recurrent miscarriages with a 15% increase in the live birth rate.
Until now, many families have found it difficult to get progesterone, despite our research and the evidence of its benefits to certain pregnant people. This is because healthcare professionals can be reluctant to prescribe treatments which aren’t recommended under national guidelines. We’re hopeful this new guidance from NICE, based on the findings of our research, will mean more parents get the help they need, when they need it.
