Last month a woman in her forties sat in my office and told me her triptan “doesn’t work anymore.” She had been given it a year earlier. When I asked how she used it, she smiled a little sheepishly: “I try to hold out. I don’t want to waste it on a headache that might go away.” By the time she swallowed the tablet, she was usually bent over with nausea and sensitive to every light in the room.
The short answer is this: a migraine medicine taken early, while the pain is still mild, works far better than the same medicine taken once the attack is in full swing. Before I call a drug a failure, I check when it was taken. In my experience, timing explains more “treatment failures” than any other single factor.
What happens in the brain when you wait
Early in a migraine attack, the pain signal depends on nerve endings around the blood vessels of the head. Triptans and similar drugs act at those endings. As the attack goes on, the nerve cells deeper in the brain become sensitized and start firing on their own, no longer needing much input from the outside. At that point, a drug that works at the periphery has much less to act on.
You can feel this change. It is called allodynia: your scalp becomes tender, brushing your hair hurts, glasses or a ponytail feel unbearable, even a shower can sting. When I hear that, I know the window for a simple oral pill has narrowed.
The numbers from the clinical literature are striking. In one clinic study of 61 attacks, a triptan left 25 of 27 attacks (93%) pain-free at two hours when it was taken before allodynia developed, but only 5 of 34 (15%) once allodynia was established. A larger analysis of sumatriptan combined with naproxen found that you needed to treat about 3 people for one to be pain-free at two hours when treated at mild pain, but about 5 when treated at moderate or severe pain. Same drug, very different result.
“But what if it isn’t a migraine?”
This is the fear behind most delay, and it is a fair one. Nobody wants to take medicine for nothing, and there is a real limit on how often you can take it (more on that below). My advice is to treat at the first certain sign that this is one of your migraine attacks, not to wait and see whether it becomes one. For most people with established migraine, the first twenty minutes are recognizable: the particular spot behind one eye, the neck stiffness that always comes first, the nausea, the light sensitivity. If you know your own pattern, you can act on it.
If you are still unsure whether your headaches are migraine at all, that is a diagnosis question rather than a timing question, and it is worth settling first. I wrote about how often the label is wrong in Headache Not Getting Better? What Doctors Miss.
Matching the first drug to the attack, not to your fear
A second habit I try to change is the “earn the strong drug by failing the weak one” approach, where people are told to start with an over-the-counter painkiller and move up only when it fails. A randomized trial of 835 patients compared this stepwise approach with stratified care, in which the first treatment is chosen by how disabling the attacks usually are. Two-hour headache response was about 53% with stratified care versus about 41% and 36% with the two stepwise approaches, and disability time was lower.
In practice, that means:
- Mild to moderate attacks that you can function through: a full-dose anti-inflammatory such as ibuprofen 400 to 600 mg or naproxen 500 mg, taken at the start. Under-dosing is common; see Ibuprofen Not Working for Your Migraine?
- Attacks that regularly knock you out of work or family life: a migraine-specific drug (a triptan, or a gepant if triptans are not suitable) taken early, rather than after a string of failed painkillers.
- Nausea or early vomiting: an anti-nausea medicine alongside, because a stomach that has stopped moving cannot absorb the pill. If you vomit early, a non-oral form (nasal spray or injection) may be needed.
Before you decide a drug has failed
A common standard among headache specialists is that a triptan has truly failed only if it gave an inadequate response in at least two of three attacks that were treated early, at a full dose, and with a route the body could absorb. Failure of one triptan does not predict failure of the next, so a second and third are worth trying, including non-oral forms. If it works but the headache returns within a day, that is a different problem with different fixes, which I describe in Migraine Came Back Hours Later?, and if triptans have genuinely been exhausted, Triptans Not Working? What a Neurologist Tries Next walks through the options.
Taking medicine early comes with an important ceiling. Acute treatment of any kind should stay under 10 days a month, or under 15 days a month for simple painkillers alone. Beyond that, the medicine itself can start driving more headaches, the pattern I explain in Painkillers Causing Your Daily Headache? If treating early means you are reaching for pills more than two or three days a week, the answer is not to wait longer. It is to start a preventive treatment so there are fewer attacks to treat.
What I asked the woman in my office to do
We kept her triptan but changed three things: take it at the first reliable sign of her usual attack, take an anti-nausea tablet with it, and keep a simple diary of the time of dosing and the result for her next three attacks. At her follow-up she said the second attack had been over in about an hour. The drug had not changed. The timing had.
A note of caution: if a headache is the worst of your life, comes on like a thunderclap, or arrives with weakness, confusion, fever, or a stiff neck, do not sit at home timing your pills. Those are emergencies.
