At a glance
- NSAIDs like ibuprofen or naproxen are the best-evidenced option for premenstrual headache pain, especially if your headaches follow a migraine pattern tied to your cycle.
- Vitamin B6, taken daily up to 100mg, showed modest benefit for PMS symptoms overall across nine trials and 940 women, though trial quality was mixed (BMJ, 1999).
- Chasteberry (Vitex agnus-castus) has supportive evidence from a 2017 meta-analysis of 17 randomized trials for PMS symptoms, though headache specifically wasn't the main outcome tested.
- Start an NSAID as soon as pain begins or the evening before a predictable headache day. Give a supplement two to three cycles of daily use before judging it.
- A headache that takes a week or more of every cycle, or that suddenly changes, is worth a doctor's attention.
Strength of evidence
Mixed evidence
NSAIDs have strong guideline support for migraine, including the menstrual pattern, but few trials test headache alone before a period. Vitamin B6 and chasteberry have trial evidence for PMS symptoms overall, though many studies are small or lower quality, so evidence specific to headache is limited.
What is the best treatment for headaches before your period?
The best-evidenced treatment for a headache before your period is an NSAID like ibuprofen or naproxen, taken as soon as pain starts or right before you expect it. For headaches that follow a migraine pattern tied to your cycle, the French Headache Society's 2021 guideline covers menstrual migraine as a distinct situation needing its own management plan [1].
Premenstrual headaches often follow the drop in estrogen in the days before bleeding. For some people, that drop lowers the threshold for migraine, so a headache around your period can feel different from one at any other time of the month. Headaches before your period walks through why this happens in more detail.
Ranked by strength of evidence, your options look like this:
- NSAIDs (ibuprofen, naproxen): guideline-recommended first-line treatment for migraine attacks, including menstrual migraine [1].
- Vitamin B6: modest evidence for easing PMS symptoms generally, from a systematic review of nine trials [5].
- Chasteberry (Vitex agnus-castus): evidence from multiple trials for PMS symptoms overall, though quality varies [2].
- Chamomile and other herbal options: early evidence, from smaller and lower-quality trials [3] [4].
- Acupuncture: some trial evidence for PMS symptoms, though study quality is mixed [7].
None of these are headache-specific trials. Most test overall PMS symptom relief, with headache as one of several symptoms measured.
Do over-the-counter options help?
Yes. NSAIDs are the standard first treatment for migraine attacks, and the French Headache Society's 2021 guideline includes menstrual migraine in that recommendation [1]. Ibuprofen and naproxen both work by lowering prostaglandins, the chemicals that widen blood vessels and sensitize pain nerves during a headache.
Taking an NSAID early, before the pain builds to its worst, tends to work better than waiting. If you know your headache usually lands on a specific day of your cycle, that's the day to have it on hand.
Side effects at standard over-the-counter doses are usually mild, mainly stomach upset, which taking them with food helps avoid. People with stomach ulcers, kidney problems, or who take blood thinners should ask a pharmacist before regular use.
Acetaminophen (paracetamol) is a gentler option if NSAIDs don't sit well with you, though the guideline evidence for migraine specifically favors NSAIDs [1].
If your headaches keep a tight pattern with your cycle, a Daily Record of Severity of Problems (DRSP) chart can show your doctor exactly which days to target, and whether an NSAID taken a day early would catch the headache before it starts.
What natural options have evidence?
A few natural options have trial evidence for premenstrual symptoms generally, though few trials isolate headache as the outcome.
Vitamin B6 has the most tested evidence. A 1999 systematic review of nine trials and 940 women found an odds ratio of 2.32 for overall symptom improvement over placebo, at a trial dose up to 100mg a day [5].
Chasteberry (Vitex agnus-castus) showed benefit across a 2017 meta-analysis of 17 randomized trials, though dosing and preparation varied by study [2].
A small 2020 pilot trial found a broader micronutrient blend worked about as well as vitamin B6 for PMS overall; the PMDD subgroup showed a numerically larger effect with the micronutrient blend, though this difference wasn't statistically significant [8].
Chamomile and acupuncture both have some supporting trials, but they're smaller and lower quality, so the evidence is more limited [3] [7].
| Option | Evidence | Typical dose | Notes |
|---|---|---|---|
| Vitamin B6 | Modest, from lower-quality trials | Trial dose (short-term, studied in trials) [5] | Odds ratio 2.32 for symptom improvement vs placebo [5]. Doses above 10mg/day long-term carry a risk of nerve damage, so don't take more than the trial dose without medical advice. |
| Chasteberry (Vitex) | Moderate, across several RCTs | Varied by trial | Reviewed across 17 RCTs [2] |
| Micronutrient blend | Small pilot trial | Not standardized | Comparable to B6, larger effect in PMDD subgroup [8] |
| Chamomile | Limited, small trials | Not standardized | Systematic review of 8 RCTs [3] |
| Acupuncture | Mixed quality | Not standardized | Systematic review of 8 RCTs [7] |
None of these are a cure, and dosing wasn't standardized across trials. If you want to try one, start with a single option for two or three cycles and track whether your headache pattern actually changes, rather than switching things every month.
When should you start taking something?
Timing matters as much as the treatment itself. For NSAIDs, the clearest approach is to start as soon as the headache begins, or the evening before if you know which day it usually lands.
For supplements, the trials that showed benefit used them continuously through the whole cycle, not just when the headache showed up.
- Track your cycle for two cycles first, noting the day your headache usually starts.
- If trying an OTC option, keep it on hand on and before that day.
- If trying a supplement like vitamin B6 or chasteberry, take it daily and give it two to three cycles before judging whether it helps.
- Note the result on a DRSP chart so you can see the pattern instead of relying on memory.
Some PMDD research has tested starting medication only after symptoms begin, rather than daily all month. A 2015 trial found symptom-onset dosing of an antidepressant (sertraline) worked for the mood symptoms of PMDD, though this wasn't tested for headache specifically [6]. That's a decision for your doctor, not something to start on your own.
If your main struggle right now is the wider wave of symptoms around the headache, the wider PMS treatment options cover that broader picture.
When should you see a doctor?
Most premenstrual headaches respond to the options above within a cycle or two. A headache that's new, severe, or different from previous ones is worth medical attention, since sudden changes sometimes point to other causes first.
See a GP or gynecologist if:
- Your headache takes a week or more of every cycle, even with treatment.
- The pattern feels like a clear menstrual migraine, since some hormonal contraceptives and other options need medical guidance [1].
- Headaches come with mood swings, rejection sensitivity, irritability or anxiety through most of the cycle, which fits premenstrual syndrome more broadly, or with a tighter pattern that fits PMDD.
Bring two months of daily notes, ideally from a DRSP chart, so your doctor can see which days are affected and how severe they get. That record helps decide between NSAIDs, hormonal options, or a referral to a PMDD specialist if your symptoms go well beyond headache.

Systematic review, 2023
What hormonal treatments have been tested for PMDD, menstrual migraine, and catamenial epilepsy?
Hormonal treatments have been tested 56 times for premenstrual mood disorder, 21 times for menstrual migraine, and 8 times for catamenial epilepsy. Combined oral contraceptives were a frequent focus.
Strong study design
Cohort study, 2022
Can women accurately tell if they have period-related migraines, or do they need to track them?
No. Women couldn't accurately tell if they had period migraines. Most needed to keep a daily headache diary for several cycles for accurate diagnosis.
Strong study design
Guideline, 2021
How should migraine be managed in women, particularly menstrual migraine?
This guideline covers migraine treatment approaches, noting that menstrual migraine, pregnancy, contraception, and hormone therapy are specific considerations. The abstract does not provide specific treatment details for menstrual migraine.
Strong study design
Randomised trial, 2016
Does telcagepant prevent migraines during the menstrual period?
Telcagepant did not reduce overall monthly migraine days. However, it did reduce headaches on the days it was taken around the period. It was generally safe.
Strong study design
Randomised trial, 2014
Does the combination of sumatriptan and naproxen sodium reduce menstrual symptoms and migraine?
Yes. The combination was better than placebo for tiredness, irritability, bloating, abdominal pain, and back pain, as well as migraine. However, women with severe period pain responded less well to migraine treatment.
Strong study design
Randomised trial, 2005
Does sumatriptan work for migraines around the menstrual cycle?
Yes, sumatriptan 100 mg gave headache relief to 67% of women for migraines during their menstrual window compared to 33% on placebo. Sumatriptan was well tolerated.

Questions people ask
Does ibuprofen help PMS headaches?+
Ibuprofen can help PMS headaches, since NSAIDs are a guideline-recommended first treatment for migraine, including the menstrual pattern some people get before their period. Taking it as soon as pain starts, rather than waiting, tends to work better. Side effects are usually mild at standard doses, mainly stomach upset.
Does vitamin B6 help premenstrual headaches?+
Vitamin B6 has modest evidence for easing PMS symptoms overall, from a systematic review of nine trials and 940 women, at doses up to 100mg a day. The trials were mostly low quality, and none isolated headache as the only outcome measured, so evidence for headache specifically is limited.
Does chasteberry (Vitex) help period headaches?+
Chasteberry (Vitex agnus-castus) has supportive evidence from a meta-analysis of 17 randomized trials for PMS symptoms overall. Headache specifically wasn't the focus of most trials. If you want to try it, give it two to three cycles and track whether your headache pattern changes.
When should I start treatment for a premenstrual headache?+
Start an NSAID as soon as a premenstrual headache begins, or the evening before if you know which cycle day it usually lands. Supplements like B6 or chasteberry are taken daily through the cycle in the trials that tested them, not just on headache days.
When is a premenstrual headache a sign of something more serious?+
A premenstrual headache that's new, severe, or different from your usual pattern deserves medical attention, since sudden changes sometimes point to other causes. If it takes a week of every cycle despite treatment, bring two months of daily notes to a GP or gynecologist appointment.
