Every woman has the right to informed consent

Fighting for justice for women and families suffering the devastating effects of hormone pregnancy tests.
But we can only do it with your support.


Our Story

In the 1960s and 70s, thousands of women were given the oral hormone pregnancy test Primodos. Today, there is more evidence to suggest this drug caused life changing and devastating congenital abnormalities, stillbirths and miscarriages. The Association for Children Damaged by Hormone Pregnancy Tests (ACDHPT) is campaigning to expose the truth about the failures of both past and present Government Regulatory Agencies and the continuing cover up by the drug company Bayer/Schering. We have had to fight to bring this scandal into the open, to ensure our families are recognised as innocent victims of an unnecessary drug and absolved of any guilt at the tragic results.
It is now time to place the blame where it belongs, with the Regulators and the Manufacturer, to allow our families to finally shed the guilt they have carried for more than 50 years. It is now time for Justice.

Marie Lyon, Chair, ACDHPT.

How Can You Help?

Sky News Primodos

The ACDHPT works together with our Legal Team PGMBM, to provide research and evidence which will support and strengthen our legal claim. This also involves working closely with MPs in the House of Commons and the House of Lords. Together, we ensure that past regulatory failures are acknowledged, and current regulatory failures exposed, to ensure we move from a protect and deny culture to an open and listening one. Only by listening to patients can we ensure these avoidable harms never happen again. We feel a moral responsibility to hold the Government and Manufacturer to account, to protect future generations from unnecessary and untested drugs.

Membership of the Association is available to anyone who has been affected by a hormone pregnancy tests (HPT), Primodos or Amenerone Forte. Members bring invaluable support as each new member offers an opportunity to increase our MP support and provide additional funding for our research and campaign. The progress we have made to uncover the scandal and launch the IMMDS review would not have been possible without the nominal subscriptions provided by our families and the vital support of MPs.

Finally, we understand that after 50 years, it can be difficult for those affected to acknowledge and discuss many of the personal issues surrounding Primodos. We understand, and ensure complete confidentiality of your support if you wish.

If you have been moved by our campaign but have not been directly affected by a HPT, we still need your help. Please see how you can support us or donate to help fund our fight for justice.



Primodos prescribed as a convenient new method of pregnancy testing.


Dr. Isabel Gal produces the first comprehensive study identifying the association between HPTs and congenital abnormalities.


First warning re: HPTs/Primodos from Government Health Regulators.


Second warning started: "The association has been confirmed".


Primodos taken off the market in the UK.


The Association (ACDHPT) was formed and received 800 family members.


Expert Working Group commissioned by the UK Government concluded there was no association.


Baroness Cumberlege was asked to Chair an Independent Medicines and Medical Devices Safety Review, which concluded there was an association between HPTs/Primodos and adverse effects. The Report, published on 8th July 2020, concluded that Primodos should have been removed from the Market in 1967, immediately after the publication of Dr. Gal's Study.

Fight For Justice

We have campaigned for over 40 years in our fight for justice. The Cumberlege Review marks a significant step forward acknowledging the colossal impact of Primodos. We continue the fight to ensure that the NHS, regulators, manufacturer, policy makers and healthcare system admit that mistakes were made and that patients should now be compensated for these failings.

1. Mistakes Acknowledged

The mistakes of the past must be acknowledged by the manufacturer of Primodos – Bayer AG, who now own Schering AG, the original creator of Primodos.

2. Cultural Change

All the recommendations from the Cumberlege Review published in July 2020 to be implemented by the UK Government

3. Financial Redress

To acknowledge and redress the avoidable harms Mothers suffered, from miscarriage, stillbirth and life changing congenital abnormalities. To support Families still caring for their badly damaged children, more than 40 years after taking an unnecessary oral hormone pregnancy test.
