Menstrual migraine: definition and meaning
A menstrual migraine is a migraine attack that happens regularly in the window from 2 days before to 3 days after a period starts, in at least two out of three cycles. It is thought to be triggered by the drop in estrogen before a period. These attacks are often longer and harder to treat than other migraines.
Two types
- Pure menstrual migraine: attacks only happen around the period.
- Menstrually related migraine: attacks happen around the period and at other times too. This is much more common.
Why it happens
Estrogen falls sharply in the last days of the luteal phase. In people prone to migraine, that withdrawal seems to make the brain more sensitive. Prostaglandins, released as the uterine lining breaks down, may add to it. Migraines can also cluster during the pill-free week or in perimenopause, when estrogen swings.
What helps
- Track it: a diary of attacks and cycle days for 2 to 3 months confirms the pattern.
- Treat early: standard migraine medicines work best at the first sign.
- Short-term prevention: doctors sometimes suggest anti-inflammatories or a triptan for a few days before an expected attack, if your cycle is regular.
- Hormonal options: for some, steadier hormones help. Combined pills aren't suitable for people with migraine with aura.
For milder period headaches, see period headaches. Pain and poor sleep can pull mood down too, so a migraine week often feels emotionally heavier.
Get urgent help for a sudden, severe "worst ever" headache, a headache with weakness, confusion, a stiff neck or fever, or a new pattern of headaches after 50.
Frequently asked questions
Is a menstrual migraine worse than a normal migraine?
Often, yes. Studies suggest menstrual attacks last longer, are more severe and respond less well to treatment.
Do menstrual migraines stop after menopause?
For many people they improve once periods stop, though they can get worse in perimenopause first.
