Migraine and HRT: what to log
Migraine with aura is a genuine caution for combined hormonal contraception, and that caution gets carried over into conversations about HRT where it doesn't actually apply. NICE guidance treats the two differently: migraine, including migraine with aura, is not a reason HRT is withheld.
Two different products, one confused rule
The stroke-risk caution attached to migraine with aura comes from research on combined hormonal contraception, which uses a different type and dose of oestrogen than menopausal HRT. NICE's menopause guideline is explicit that women with migraine, including migraine with aura, can be offered HRT — it is not on the list of things HRT is withheld for. If a prescriber has said otherwise, it's worth asking specifically whether they're applying the contraceptive-pill caution to a different product by mistake; this is a documented, common mix-up.
Why route sometimes comes up in the conversation
Where migraine is part of someone's history, guidance points toward starting with a transdermal route — patch or gel — rather than a tablet, because it delivers a steadier level of oestrogen. Migraine frequency for some people tracks with hormone fluctuation more than with the hormone level itself, so a steadier delivery method is the more common starting choice where migraine is a factor. This is a preference to discuss, not a rule that overrides what already works for you.
If a new-onset migraine with aura appears only after starting HRT, the usual next steps discussed are switching to (or within) a transdermal route, adjusting the dose, or trying a different formulation — always as something to raise with a prescriber, not to self-adjust.
What to log
| Field | Why it matters |
|---|---|
| Migraine frequency, before and after a change | Shows whether a route or dose change tracks with a real difference, not chance |
| Whether aura is present, and any change in aura pattern | New or changed aura is always worth flagging promptly, HRT or not |
| Route and dose at the time | So a pattern can be matched to what was actually being taken |
| Timing relative to the change | A shift in the first few weeks reads differently from one months later |
See HRT formulations explained for what patch, gel, spray and tablet actually mean, without doses. See How to log an HRT dose change for the dated-entry format that makes this pattern visible at a review appointment.

About HormoneLog
HormoneLog is an iOS app from Baker Ventures LLC for tracking perimenopause and menopause symptoms and keeping an HRT record: what you took, at what dose, from when, and what changed afterwards. It is built for the appointment, where "it has been bad lately" is worth far less than a dated record of frequency and severity. The app is in development.
HormoneLog is a record-keeping tool. It does not diagnose, does not score you, and makes no claim about symptom relief. The guides on this site link to NICE, the NHS, the Menopause Society and peer-reviewed sources, and say plainly where the evidence is thin. Everything here is free and needs no account.
Questions and answers
Does migraine with aura mean I can't take HRT?
No. NICE guidance distinguishes HRT from combined hormonal contraception on this point — migraine with aura is a caution for the contraceptive pill, not for HRT. This is a common point of confusion, including among some prescribers.
Does the form of HRT matter for migraine?
NICE guidance points toward transdermal oestrogen (patch or gel) where migraine is a factor, because it keeps hormone levels more stable than a tablet, which can matter for headache frequency. This is a route preference, not a rule.
What should I log if I have migraine and I'm starting or changing HRT?
Whether migraines change in frequency or character after starting or changing HRT, and whether that follows a switch in route or dose. A pattern over several weeks is what a review appointment can act on.
Can HormoneLog tell me if my HRT is causing my migraines?
No. HormoneLog records what you log. Whether a headache pattern is related to a hormone change, and what to do about it, is a clinical judgement for your prescriber.
