Medicines for Heavy periods
Menstrual bleeding heavy enough to interfere with everyday life and to risk iron-deficiency anaemia, usually treatable with medicines that reduce blood loss or hormonal options, after checking for any underlying cause.

Quick answer
What is Heavy periods?
Heavy periods, sometimes called menorrhagia or heavy menstrual bleeding, means losing enough blood during a period that it affects your daily life — needing to change pads or tampons very often, doubling up on protection, flooding through to clothes or bedding, passing large clots, or planning your day around the bleeding. What counts as "heavy" is partly about the impact on you rather than a fixed measurement.
- How it is treated: The goals are to reduce the bleeding to a level that no longer disrupts life, to prevent or treat any anaemia, and to deal with an underlying cause where one is found.
- Self-care: Heavy periods are best managed with medicines and treating any underlying cause rather than lifestyle change alone, but eating iron-rich foods and getting iron levels checked helps guard against the tiredness of anaemia.
- When to seek help: See your GP if periods are heavy enough to disrupt your life, are getting heavier, or leave you feeling tired or breathless, which can point to anaemia.
What it is
Heavy periods, sometimes called menorrhagia or heavy menstrual bleeding, means losing enough blood during a period that it affects your daily life — needing to change pads or tampons very often, doubling up on protection, flooding through to clothes or bedding, passing large clots, or planning your day around the bleeding. What counts as "heavy" is partly about the impact on you rather than a fixed measurement. Persistent heavy bleeding can lead to iron-deficiency anaemia, causing tiredness and breathlessness, which is one reason it is worth treating rather than putting up with. Often no specific cause is found, but heavy periods can be linked to conditions such as fibroids, polyps, adenomyosis, thyroid problems or, less commonly, a bleeding disorder, so an assessment looks for these. A blood test to check for anaemia, and sometimes an examination or scan, helps guide what is going on and what will help.
How it is treated
The goals are to reduce the bleeding to a level that no longer disrupts life, to prevent or treat any anaemia, and to deal with an underlying cause where one is found. For people who do not need contraception, tranexamic acid, taken only during the days of the period, can noticeably reduce blood loss, and an anti-inflammatory (NSAID) can help where there is pain as well as heavy bleeding. Hormonal options are often very effective: the hormonal intrauterine device (a coil that releases progestogen) is frequently recommended as a first-choice long-term option because it greatly reduces bleeding, and the combined pill is another hormonal route that can lighten periods and offers contraception too. Iron deficiency is checked for and treated alongside, since correcting anaemia is part of feeling well again. If bleeding stays heavy despite these steps, or a cause such as fibroids needs specific treatment, referral for further investigation or procedures is the next stage.

Lifestyle and self-care
Heavy periods are best managed with medicines and treating any underlying cause rather than lifestyle change alone, but eating iron-rich foods and getting iron levels checked helps guard against the tiredness of anaemia.
When to get help
When to see a doctor
See your GP if periods are heavy enough to disrupt your life, are getting heavier, or leave you feeling tired or breathless, which can point to anaemia. Seek prompt advice for flooding or very large clots, bleeding between periods or after sex, or any bleeding after the menopause, as these need to be checked.

Answers
Heavy periods: frequently asked questions
What medicines are used for heavy periods?
The main options are tranexamic acid, taken only during the period to reduce blood loss, and anti-inflammatory painkillers (NSAIDs), which lessen both bleeding and pain. Hormonal options are often very effective too: the progestogen-releasing intrauterine device (the hormonal coil) is frequently a first-choice long-term treatment, and the combined pill can also lighten periods while providing contraception. The best choice depends on whether you want contraception, any underlying cause, and your medical history.
Why does the hormonal coil get recommended so often?
The hormonal coil, which slowly releases a progestogen into the womb, is frequently recommended as a first-choice long-term option for heavy periods because it greatly reduces blood loss for most people, lasts for years and provides contraception at the same time. Periods often become much lighter, and for some they stop altogether. Your clinician can talk through whether it suits you and what to expect when it is first fitted.
Can heavy periods make me anaemic?
Yes. Losing a lot of blood month after month can lower your iron stores and lead to iron-deficiency anaemia, which causes tiredness, breathlessness and sometimes looking pale. This is one reason heavy periods are worth treating rather than tolerating. A simple blood test can check for anaemia, and iron treatment alongside controlling the bleeding usually helps you feel better.
Do heavy periods always mean something is wrong?
No — often no specific cause is found, and the bleeding can still be treated effectively. But heavy periods can sometimes be linked to conditions such as fibroids, polyps, thyroid problems or a bleeding disorder, so an assessment looks for these. Bleeding between periods, after sex or after the menopause is not part of normal heavy periods and should always be checked.
