Migraine and the pill: aura is the dividing line

Migraine and the contraceptive pill come up together for a specific reason. For most people who get migraines the pill is perfectly fine. But there is one form of migraine, migraine with aura, that changes the picture entirely, because combined with oestrogen it raises the risk of stroke.

Knowing which type you get is one of the most important things we establish. This article explains the difference and what it means for you.

What aura actually is

Aura is a set of temporary neurological symptoms that come on before or at the start of a migraine, usually lasting between 5 and 60 minutes. The most common is visual: a blind spot, a shimmering or zigzag line, or flashing lights that spread across your vision. Aura can also involve tingling or numbness spreading up an arm, or trouble finding words. The key features are that it builds up over minutes and then fades, and it happens around the headache.

Ordinary migraine without aura is just the headache, often one-sided and throbbing, with nausea or sensitivity to light and sound, but without those preceding neurological symptoms. Feeling generally off, tired, or irritable before a migraine is not aura.

Why aura matters for the combined pill

Migraine with aura is itself associated with a small increase in the risk of ischaemic stroke, the kind caused by a blocked blood vessel. Adding the oestrogen in a combined pill increases that risk further. The two together push it high enough that the national safety guidance treats migraine with aura, at any age, as a reason not to use the combined pill. This is one of the clearest lines in contraceptive prescribing.

What you can take instead

If you get migraine with aura, the progestogen-only pill is safe and is the recommended route. It contains no oestrogen, so it does not carry the same stroke risk, and it works just as well at preventing pregnancy. Long-acting progestogen methods are also safe. In other words, having aura narrows the choice but does not leave you without good options. This is one of the clearest examples of why having more than one type of pill matters: a fact that closes one door opens another.

How common is aura, and how sure do we need to be

Aura affects roughly a quarter to a third of people who get migraines, so it is far from rare. Because the safety stakes are real, we ask about it carefully rather than in passing. If you are not sure whether what you experience counts as aura, describe it as best you can and the doctor will help work it out. When it is genuinely unclear, we err on the side of caution and treat it as aura, which usually means choosing a progestogen-only method. That is a small trade-off for removing a stroke risk you cannot feel coming.

Migraine without aura

If your migraines do not come with aura, the combined pill can usually be used, taking your other risk factors into account. Occasionally the combined pill makes migraines worse, often during the hormone-free break when oestrogen levels drop. If that happens, running packets together to avoid the break, or switching to a progestogen-only method, can help. If you only get migraines around the time of your period, that pattern is common and does not by itself rule out the combined pill.

If migraine changes after starting the pill

This part is important. If you start getting aura for the first time while on a combined pill, or your migraines suddenly become much more frequent or severe, stop the combined pill and get reviewed. A new aura on the combined pill is a clear signal to move away from oestrogen.

When migraine needs its own attention

If you get frequent or disabling migraines, the contraception question is only part of the picture, and the migraines themselves deserve proper management. Keeping a simple diary of when migraines happen and what they feel like makes that conversation much easier, and helps the doctor judge the aura question. And if you ever have neurological symptoms that do not fit your usual aura, last much longer than an hour, or come on with the worst headache of your life, treat that as urgent rather than assuming it is a migraine.
