Women face financial barriers to filling prescriptions, or regular healthcare, due to cost, a new report on women's health has found.
Women living rurally and disabled women struggle to reach services, or find that the facilities lack the equipment, accessibility, or staffing to meet their needs.
The report, 'Our Health, Our Voices', is the result of a collaboration project between the National Women's Council and the Department of Health.
It says many women reported experiencing discrimination based on ethnicity, disability, age, gender identity, or sexual orientation.
There were also problems due to language barriers, literacy challenges, and lack of interpretation supports.
NWC Head of Policy Doireann Crosson said that while there have been many really positive advancements in women's health, the study found that these advancements have not reached all women equally.
She said that marginalised women in Ireland continue to face significant health inequalities and persistent barriers to care.
Ms Crosson said that the next Women's Health Action Plan should prioritise more targeted, inclusive and culturally propriate implementation of healthcare services.
Salome Mbugua, Chief Executive of AkiDwA, a national network for migrant women, said it was shocking and unacceptable that so many migrant women, including women and families who have lived in Ireland for years, cannot access a GP, due to a GP shortage.
She said that without this crucial link to primary care, migrant women cannot access essential services such as potentially life-saving screening programmes, free contraception, HRT and other services.
The Department of Health said that €180 million has been invested in women's healthcare in the last five years.
It said this has enabled the delivery of new services including specialist menopause clinics, fertility hubs, State-funded Assisted Human Reproduction services, as well as free contraception.
