Medicines for Endometriosis
A long-term condition where tissue similar to the womb lining grows outside the womb, causing painful and often heavy periods, pelvic pain and sometimes fertility problems — managed, not cured, with pain relief, hormonal treatment and, for some, surgery.

Quick answer
What is Endometriosis?
Endometriosis is a long-term condition in which tissue similar to the lining of the womb grows in other places, such as the ovaries, the pelvis and the tissues around the womb. Each month this tissue responds to hormonal changes much as the womb lining does, but it has no way to leave the body, which can lead to inflammation, pain and scar tissue.
- How it is treated: The aim is to control symptoms and protect fertility where that matters, accepting that endometriosis is managed rather than cured.
- Self-care: Heat (such as a hot water bottle), gentle activity, pacing and rest during flare-ups, and support for the emotional impact of living with long-term pain can all help.
- When to seek help: See your GP if you have persistent or severe period or pelvic pain, pain during sex, or pain that stops you doing everyday things — and ask about referral to a gynaecology or specialist endometriosis service if symptoms are not controlled.
What it is
Endometriosis is a long-term condition in which tissue similar to the lining of the womb grows in other places, such as the ovaries, the pelvis and the tissues around the womb. Each month this tissue responds to hormonal changes much as the womb lining does, but it has no way to leave the body, which can lead to inflammation, pain and scar tissue. Typical symptoms include painful periods, persistent pelvic pain, pain during or after sex, pain when opening the bowels or passing urine, heavy periods and, for some women, difficulty becoming pregnant. Symptoms vary widely and do not always match the amount of tissue present. Diagnosis is often delayed because the symptoms overlap with other conditions; a definite diagnosis is usually made by looking inside the pelvis with a keyhole operation (laparoscopy).
How it is treated
The aim is to control symptoms and protect fertility where that matters, accepting that endometriosis is managed rather than cured. Pain is treated with simple pain relief such as anti-inflammatory medicines and paracetamol. Hormonal treatment is used to quieten the tissue and reduce bleeding and pain: options include the combined pill (sometimes taken without the usual break), progestogen-only treatments, the hormonal coil and, under specialist care, GnRH-based treatments that switch off the ovaries for a time. Surgery to remove or destroy the tissue helps some women, and a specialist endometriosis service may be involved for complex disease. When fertility is the priority, hormonal treatments that prevent pregnancy are not appropriate and specialist fertility input is needed. Treatment is tailored to symptoms, plans for pregnancy and how the disease affects daily life, and is reviewed over time.

Symptoms that can point to Endometriosis
Endometriosis can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Heat (such as a hot water bottle), gentle activity, pacing and rest during flare-ups, and support for the emotional impact of living with long-term pain can all help. Some women find that tracking symptoms and triggers, and accessing pain-management or fertility support early, makes the condition easier to live with.
When to get help
When to see a doctor
See your GP if you have persistent or severe period or pelvic pain, pain during sex, or pain that stops you doing everyday things — and ask about referral to a gynaecology or specialist endometriosis service if symptoms are not controlled. Sudden severe pelvic pain, heavy bleeding that soaks through protection quickly, fainting, or fever needs urgent assessment.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Endometriosis: frequently asked questions
What medicines are used for endometriosis?
Pain is usually treated with anti-inflammatory medicines and paracetamol. Hormonal treatments are central to reducing pain and bleeding: the combined pill (sometimes taken without a break), progestogen-only options and the hormonal coil, with GnRH-based treatments used under specialist care for more difficult disease. The right choice depends on your symptoms and whether you are trying to conceive.
Can endometriosis be cured?
There is no cure, but the condition can usually be managed so that symptoms are controlled. Treatment focuses on relieving pain, reducing heavy bleeding and protecting fertility where that matters, and may be adjusted over the years as needs change.
Will endometriosis affect my chances of having a baby?
Many women with endometriosis conceive naturally, but it can make becoming pregnant harder for some. If fertility is a concern, hormonal treatments that prevent pregnancy are not suitable and specialist fertility input is important — so it is worth raising plans for pregnancy early.
Why has my diagnosis taken so long?
Endometriosis symptoms overlap with several other conditions, and period pain is often assumed to be normal, so diagnosis is frequently delayed. A definite diagnosis usually needs a keyhole operation to look inside the pelvis. If your pain is being dismissed, it is reasonable to ask for further assessment or specialist referral.
