Premenstrual symptoms come from the ordinary hormone shifts of the second half of the cycle, and in their severe, mood-dominated form, premenstrual dysphoric disorder (PMDD), they are a treatable DSM-5 diagnosis. The mood symptoms respond to SSRIs more than to any other treatment measured, and cognitive behavioral therapy, the drospirenone combined pill, calcium and regular activity each help. Confirming the pattern comes first: chart symptoms forward across two cycles, because memory overstates them, and a mood problem that only flares premenstrually needs different care.
Calcium is the best-supported supplement, evening primrose oil does little, and chasteberry and a pattern-matched Xiao Yao San formula show early promise. PMDD carries a raised risk of suicidal thoughts, which is why severe premenstrual mood is treated early.

What It Is
Premenstrual symptoms are the physical and emotional changes that arrive in the days before a period and clear once bleeding starts:
- Physical: bloating, breast tenderness, headaches, and disrupted sleep.
- Emotional: irritability, low mood, anxiety, and a sense of being overwhelmed.
Most women notice some of this. The label PMS applies when the symptoms are troublesome enough to matter, and timing defines it: they fall in the luteal phase, the second half of the cycle, and lift soon after the period comes.
Premenstrual dysphoric disorder, PMDD, is the severe form, dominated by mood. Marked irritability, anger, depressed mood and anxiety build in the luteal phase and disrupt work and relationships. It is a diagnosis in the DSM-5, and it is treatable.
Severe premenstrual mood carries a raised risk of suicidal thoughts, which is a reason to get help early.
Confirming it takes one step: prospective daily charting across at least two cycles. Memory of past cycles overstates premenstrual symptoms, so recall-based estimates roughly double the confirmed rate, and standardized scoring of two cycles of daily ratings agrees with an expert diagnosis about 98% of the time. Charting forward also separates a premenstrual disorder from depression, anxiety or another condition that runs all month and worsens before a period; that pattern is present throughout the cycle and needs treatment for the underlying condition.
Women with PMS have normal hormone levels. The symptoms come from an unusual sensitivity to the ordinary rise and fall of hormones across the cycle. That sensitivity is why two kinds of treatment help: those that quiet the body's response to the cycle, and those that switch the cycle off.
What helps
The findings below are graded by how well each one is established and how much it changes the symptoms. The mood symptoms have the strongest treatments; the physical symptoms have fewer well-tested options.

Mood & stress
SSRIs cut premenstrual symptoms more than any other treatment measured (SMD -0.57)
SSRIs are the best-evidenced treatment for the mood symptoms of PMS and PMDD. Taking one every day works a bit better than taking it only in the two weeks before a period, and both work. Side effects such as nausea and lowered libido are common.
A 2024 Cochrane review pooled 34 randomized trials of fluoxetine, paroxetine, sertraline, escitalopram and citalopram against placebo. SSRIs probably reduce overall self-rated premenstrual symptoms (SMD -0.57, 95% CI -0.72 to -0.42; 12 studies, 1742 participants; moderate-certainty). Continuous dosing was more effective than luteal-phase dosing (continuous SMD -0.69 vs luteal -0.39; subgroup difference P = 0.03). Adverse effects were consistently more common than placebo, including nausea (OR 3.30), insomnia (OR 1.99), sexual dysfunction or decreased libido (OR 2.32) and fatigue (OR 1.52). SSRIs are the first-line drug treatment for PMDD and for severe PMS.
For symptoms confined to the luteal phase, luteal-only dosing keeps drug exposure and side effects lower; when symptoms are heavier or start early, continuous dosing has the edge. The choice is worth making with a prescriber.

Measurement And Diagnosis
Confirmed PMDD affects about 1.6% to 3.2% of women, fewer than recall-based studies suggest
When PMDD is confirmed properly, it affects a small minority of women, roughly 1.6% to 3% depending on the setting. Studies that rely on women recalling past cycles report about twice that, because memory overstates it.
A 2024 systematic review and meta-analysis pooled 44 studies with 48 independent samples (50,659 participants). The point prevalence was 3.2% (95% CI 1.7% to 5.9%) for confirmed PMDD and 7.7% (5.3% to 11.0%) for provisional (recall-based) diagnosis, with very high heterogeneity (I2 = 99%). Restricting to community-based samples with a confirmed diagnosis gave 1.6% (1.0% to 2.5%) with low heterogeneity (I2 = 26%). The authors conclude that studies relying on provisional diagnosis produce artificially high rates. PMS in a milder, broader sense is far more common; PMDD is the severe, diagnostic end of the spectrum.

Daily charting over two cycles confirms the diagnosis, agreeing with experts about 98% of the time
You cannot diagnose PMDD reliably from memory. When women who reported bad premenstrual symptoms tracked them day by day for two cycles, many did not actually meet the pattern. Charting forward is the step that confirms it.
The Carolina Premenstrual Assessment Scoring System (C-PASS) study followed 200 women recruited for retrospectively reported premenstrual emotional symptoms and had them complete two to four months of daily ratings on the Daily Record of Severity of Problems (DRSP). Standardized C-PASS scoring agreed with expert clinician diagnosis in an estimated 98% of cases. Consistent with earlier work, retrospective reports of premenstrual symptom increases were a poor predictor of the prospective diagnosis. This is why DSM-5 requires symptoms to be confirmed by prospective daily ratings over at least two cycles; without it, a diagnosis is only provisional.

How it works
PMS is a sensitivity to normal hormone shifts, not abnormal hormone levels
PMS is not caused by abnormal hormone levels. It is an unusual sensitivity to the normal rise and fall of hormones across the cycle. Switch the cycle off and symptoms lift; add the hormones back and they return, but only in women who have PMS.
In a landmark NIH experiment, 20 women with PMS were given leuprolide (a GnRH agonist that suppresses ovarian function) or placebo. The 10 whose symptoms improved on leuprolide were then given estradiol and progesterone, each for four weeks, in a double-blind crossover while ovarian suppression continued. Symptoms returned significantly when the hormones were added back. Fifteen women without PMS given the identical regimen had no mood change. The conclusion is that in women with PMS the symptoms represent an abnormal behavioral response to normal hormonal changes, which is why treatments that quiet the response (SSRIs) or switch off the cycle (GnRH agonists, some contraceptives) both work.

Menstrual And Pms
Cognitive behavioral therapy eases symptoms, and the benefit lasts after the course ends
Talking therapy of the cognitive behavioral kind reduces premenstrual symptoms by a small-to-moderate amount, and unlike medication its benefit tends to persist after the course ends.
A 2012 meta-analysis of 22 controlled trials of psychological and drug treatments for PMS and PMDD found cognitive behavioral interventions produced small-to-medium standardized effect sizes at post-treatment (range d+ 0.24 to 0.70) and maintained effects at follow-up (d+ 0.46 to 0.74), which was only assessed for the psychological treatments. Serotonergic antidepressants in the same analysis gave comparable post-treatment effects (d+ 0.29 to 0.58). The authors judged the overall efficacy of both approaches as not fully satisfactory and suggested combining them.
CBT is a reasonable first choice for a woman who prefers to avoid medication, or an add-on when a drug helps only partly; its lasting effect makes it worth the up-front effort.

The drospirenone combined pill eases symptoms and their daily impact (SMD -0.41)
A combined pill containing the progestin drospirenone eases premenstrual symptoms and their effect on work, social life and relationships, by a small-to-moderate amount. The placebo effect in these trials was large, and side effects are more common than on placebo.
A 2023 Cochrane review pooled five randomized trials (858 women, most diagnosed with PMDD) of a combined oral contraceptive with drospirenone and low-dose ethinylestradiol against placebo. It may improve overall premenstrual symptoms (SMD -0.41, 95% CI -0.59 to -0.24; 2 RCTs, N=514; low-quality) and functional impairment in productivity, social activities and relationships. It also increased total adverse effects (OR 2.31) and withdrawals due to adverse effects (OR 3.41), with more breast pain, nausea and intermenstrual bleeding. The placebo also had a significant effect. Whether it beats other combined pills, or helps beyond three cycles or in milder cases, is not known.
The drospirenone pill suits a woman who also wants contraception; if the main burden is mood, an SSRI has stronger evidence, and the two are sometimes used together.

GnRH agonists strongly relieve severe PMS (SMD -1.23) but induce a temporary menopausal state
Drugs that switch off the cycle, GnRH agonists, strongly relieve severe PMS, which makes sense given the symptoms come from the cycle itself. The catch is that they induce a temporary menopausal state, so they are reserved for severe cases and used short-term.
A 2025 Cochrane review of 11 randomized trials (275 women) found GnRH agonists without add-back therapy improved global symptoms compared with placebo (SMD -1.23, 95% CI -1.76 to -0.71; 9 RCTs; high-certainty evidence for this outcome). The trade-off is that suppressing ovarian function induces a hypoestrogenic state with menopausal side effects such as hot flashes, and long-term use risks osteoporosis; women were more likely to withdraw due to adverse effects (RR 4.24). Add-back estrogen or progestogen is used to offset the menopausal state, but the review found insufficient evidence to confirm that add-back preserves efficacy, and one trial suggested estrogen-plus-progestogen add-back may worsen symptoms.
GnRH treatment is a specialist option for severe symptoms that have not responded to first-line treatment, used as a short-term break rather than an ongoing therapy because of the bone risk.

Calcium at 1200 mg a day cut premenstrual symptoms 48% by the third cycle
Calcium is one of the better-supported supplements for PMS. At about 1200 mg a day it reduced overall symptoms, including mood, water retention, cravings and pain, more than placebo, though the effect built over a few cycles.
A 1998 multicenter, double-blind, placebo-controlled trial randomized 466 women (of 497 enrolled) with moderate-to-severe, prospectively documented premenstrual symptoms to 1200 mg/day of elemental calcium as calcium carbonate or placebo for three cycles. By the third treatment cycle, calcium produced a 48% reduction in total luteal-phase symptom scores from baseline versus 30% on placebo, with all four symptom factors (negative affect, water retention, food cravings, pain) significantly reduced. The benefit emerged from the second cycle onward.
Calcium is low-risk and cheap, worth a two-to-three-cycle trial before judging it, and it doubles as bone support; food sources count toward the total.

More active women have milder premenstrual symptoms (OR 1.22 with lower activity)
Women who are more active tend to have fewer and milder premenstrual symptoms. This comes from studies that observe rather than test, so activity may not be the cause, but it is free and low-risk to build into the month.
A 2025 systematic review and meta-analysis of 82 observational studies (101,413 women) examined links between physical activity and menstrual health. Lower activity was associated with higher odds of PMS (OR 1.22, 95% CI 1.03 to 1.45; 18 studies) and of menstrual pain (OR 1.67; 21 studies). Study quality was low (mean 3.3 out of 7), most designs were cross-sectional, and physical activity was self-reported. The authors describe activity as a promising, low-cost, accessible approach while calling for standardized, prospective research.

Chasteberry is the best-studied botanical for PMS, though low-quality trials overstate it
Chasteberry has the most trial support of the herbal options for the physical symptoms of PMS, and the pooled effect looks large. The studies are low quality and inconsistent, so the true effect is likely smaller than the pooled number suggests.
A 2017 systematic review and meta-analysis found 17 randomized trials of Vitex agnus-castus for PMS, 14 poolable. Thirteen of 14 reported positive effects on total symptoms. The pooled effect in placebo-controlled trials was large (Hedges g -1.21, 95% CI -1.53 to -0.88), but heterogeneity was extreme (I2 = 91%) and most trials carried a high risk of bias, with signs of publication bias. The authors state the pooled effect should be read as exploratory and, at best, an overestimate, and call for high-quality trials against placebo, SSRIs and the pill.
Chasteberry is a reasonable option for someone who prefers a botanical for mainly physical premenstrual symptoms; it should be sourced as a standardized extract and is not advised alongside hormonal treatment without advice.

Vitamin B6 helps modestly up to 100 mg a day; higher doses risk nerve damage
Vitamin B6 helps premenstrual symptoms modestly, at doses up to 100 mg a day. The trials behind it are low quality, and higher doses are worth avoiding because B6 can damage nerves.
A 1999 systematic review of nine randomized placebo-controlled trials (940 women) found the odds of improvement in overall premenstrual symptoms with vitamin B6 were 2.32 (95% CI 1.95 to 2.54) relative to placebo, and 1.69 (1.39 to 2.06) for premenstrual depressive symptoms across four trials (541 women). The authors caution that conclusions are limited by the low quality of most trials and that doses up to 100 mg/day are likely to help. Above roughly 100 mg/day, long-term B6 carries a risk of sensory peripheral neuropathy, which caps how much is sensible to take.
Keep any B6 trial to 100 mg a day or less; more is not better here and raises the risk of nerve symptoms.

Evening primrose oil did little in the best-controlled trials
Evening primrose oil is widely sold for PMS, but the better-controlled trials found it did little. Small benefits cannot be ruled out from the thin evidence, and it is not one of the stronger options.
A 1996 systematic review searched for controlled trials of evening primrose oil for PMS and found only seven placebo-controlled studies, with clear randomization in five. Inconsistent scoring made a formal meta-analysis inappropriate. The two most well-controlled studies showed no beneficial effect, although the reviewers noted the trials were small enough that modest effects could not be excluded. Their conclusion was that on the available evidence evening primrose oil is of little value in managing PMS.

A pattern-matched Xiao Yao San formula beat placebo for PMS (P = 0.002)
A modified version of Xiao Yao San, the classic Liver Qi formula, beat placebo for premenstrual symptoms in women whose pattern matched it, with no more side effects than placebo. This is a single good trial of a pattern-matched formula, rather than a general result for herbal treatment.
A 2024 multicenter, randomized, placebo-controlled trial enrolled 144 regularly menstruating women with PMS and a Chinese-medicine pattern of Liver depression, Spleen deficiency and blood-heat, at eight sites in China. They received Jiawei Xiaoyao pill (a modified Xiao Yao San, 12 g/day) or matching placebo for three cycles. The formula reduced luteal-phase Daily Record of Severity of Problems (DRSP) scores more than placebo (P = 0.002 for the full analysis set), covering psychological and somatic symptoms, with no significant difference in adverse events. This aligns the trial evidence with the traditional Liver Qi stagnation reading behind the Xiao Yao San family.
This supports a pattern-matched Xiao Yao San formula prescribed by a practitioner who has assessed your pattern, rather than a generic formula chosen from a listing.

Alcohol is linked with higher PMS risk (OR 1.45), more so with heavy drinking (OR 1.79)
Drinking is linked with a higher chance of having PMS, and more so for heavier drinking. The studies cannot prove alcohol is the cause, but cutting back is a low-cost thing to try.
A 2018 systematic review and meta-analysis of 19 studies found alcohol intake was associated with a moderate increase in PMS risk (OR 1.45, 95% CI 1.17 to 1.79), with heavy drinking carrying a larger increase (OR 1.79, 95% CI 1.39 to 2.32). The included studies were observational (cohort, case-control and cross-sectional), and the authors specifically call for future work to avoid cross-sectional designs and to test whether there is a threshold below which alcohol has no effect.
If premenstrual symptoms are troublesome, reducing alcohol, especially heavier drinking, is a low-risk change worth trying for a couple of cycles.

Acupuncture and acupressure may ease symptoms, on small, low-quality trials
Acupuncture and acupressure may ease premenstrual symptoms compared with a sham version, but the studies are small, few and low quality, and none compared them against standard treatments like SSRIs.
A 2018 Cochrane review of five trials (277 women) found acupuncture may give a greater reduction in mood and physical PMS symptoms than sham (for example a mean difference of about -9 points on the DRSP mood and physical scales in one trial, n=67, low-quality evidence), and acupressure may reduce the proportion of women with moderate-to-severe symptoms (RR 0.64). Most findings rested on single small trials rated low or very low quality, and no study compared acupuncture or acupressure against currently recommended treatments such as SSRIs. The reviewers called for larger trials with validated outcomes and proper blinding.

SSRIs, the strongest option for the mood symptoms
An SSRI such as fluoxetine, sertraline or escitalopram reduces premenstrual symptoms more than any other treatment measured. A 2024 Cochrane review pooled 34 randomized trials against placebo, most of them measuring adverse events; in the subset that measured symptom relief, SSRIs lowered overall symptoms against placebo (SMD -0.57), and most of those trials were industry-funded. An SSRI can be taken every day or only in the luteal phase, and continuous dosing works somewhat better (SMD -0.69 continuous against -0.39 for luteal-only). The schedule is a choice to make with a prescriber, weighed against side effects that lead some women to stop.
The drospirenone combined pill
A combined pill containing the progestin drospirenone eases premenstrual symptoms and their effect on work, social life and relationships. A 2023 Cochrane review of five trials found a moderate improvement over placebo (SMD -0.41), alongside a large placebo response and more side effects. It suits a woman who also wants contraception. Where the main burden is mood, an SSRI has stronger evidence, and the two are sometimes used together.
Cognitive behavioral therapy
Cognitive behavioral therapy reduces premenstrual symptoms by a small-to-moderate amount, and the benefit tends to hold after the course ends. It is a reasonable first choice for a woman who prefers to avoid medication, and a useful add-on when a drug helps only partly.
Calcium, the best-supported supplement
Calcium is the best-supported of the supplements. At 1200 mg a day it cut total premenstrual symptom scores by 48% by the third cycle in a 466-woman trial, against 30% on placebo. The effect builds over two to three cycles, it is cheap and low-risk, and food sources count toward the total.
Regular physical activity
Women who are more active report fewer and milder premenstrual symptoms. This comes from observational studies, where lower activity carried modestly higher odds of PMS (OR 1.22), so activity may not be the cause. It is free and low-risk to build into the whole month.
GnRH agonists, reserved for severe cases
Drugs that switch off the cycle, GnRH agonists, give the largest effect measured (SMD -1.23 against placebo), which fits symptoms that come from the cycle itself. They induce a temporary menopausal state, with hot flashes and, over time, bone thinning, so they are reserved for severe symptoms that have not responded to first-line treatment and used short-term under specialist care.
The emerging botanicals
Two plant options have limited support. Chasteberry (Vitex agnus-castus) has the most trial evidence of the botanicals for the physical symptoms; thirteen of fourteen poolable trials favored it, though the trials are low quality and inconsistent, so the true effect is likely smaller than the large pooled figure. Vitamin B6 helps modestly at up to 100 mg a day, and above that it can damage nerves, so 100 mg is the ceiling. A modified Xiao Yao San formula, Jiawei Xiaoyao, beat placebo in women whose Chinese-medicine pattern matched it, covered in the Chinese medicine section below.
Where the evidence runs thin, and what to skip
Evening primrose oil is widely sold for PMS, and the two best-controlled trials found it did little, so it is not one to lean on. Acupuncture and acupressure may ease symptoms against a sham version, on small, low-quality trials with none tested against standard treatment, so they point a direction without settling it. Alcohol is linked with a higher chance of PMS (OR 1.45), more so with heavy drinking (OR 1.79), so cutting back is a low-cost change to try for a couple of cycles.
Getting Relief
None of this replaces the plan a prescriber has you on; it is how to get the most from it. Work in order: confirm the pattern first, then match the treatment to whether the burden is mainly mood or mainly physical, and give the low-risk steps a couple of cycles before judging them.
Rate your symptoms each day for two full cycles before settling on a treatment. It confirms the timing, separates a premenstrual disorder from a mood problem present all month, and shows whether the burden is mainly physical or mainly mood, which points to the right treatment.
If mood leads, an SSRI has the strongest evidence and can be taken daily or only in the luteal phase. If you also want contraception, the drospirenone pill is an option. Cognitive behavioral therapy suits anyone who prefers to avoid medication or wants a benefit that lasts.
Calcium at about 1200 mg a day, from food and a supplement together, is cheap and low-risk. The benefit builds over two to three cycles, so judge it after a few months, not a few days.
Regular activity is linked with milder premenstrual symptoms and supports mood and sleep alongside it. Aim for the whole month, not only the difficult week.
Cutting back on alcohol, especially heavier drinking, is linked with lower PMS risk. Steady sleep and regular meals across the luteal phase help with the irritability and cravings.
Chasteberry has the most support of the plant options for physical symptoms; keep any vitamin B6 to 100 mg a day or less. A Chinese herbal formula works best matched to your pattern by a practitioner, not chosen from an online listing.
Go Deeper
- Period pain: the painful-menstruation patterns and what helps, for symptoms that center on cramps rather than the premenstrual week.
- Perimenopause and menopause: the patterns of the later transition, where mood and cycle symptoms change again.
- Magnesium: often used for premenstrual bloating and mood, on the strength of small trials.
- Breathing retraining: slow, paced breathing to take the edge off the arousal that rides alongside premenstrual irritability.
The Chinese Medicine View
The Chinese Medicine View
Chinese medicine reads premenstrual symptoms mainly through the Liver, which moves the Qi and governs the smooth flow of emotion and blood in the run-up to a period. When that movement stalls, the result is the irritability, breast and rib-side distension and mood swings that many women recognize, and this is the reading behind Xiao Yao San, the free and easy wanderer formula, which is our single most-searched formula. A 2024 placebo-controlled trial gives this a modern footing: a modified Xiao Yao San formula reduced luteal-phase symptoms in women whose pattern matched it. Read the patterns as an interpretive lens a practitioner works with; a page cannot give you a diagnosis, and a practitioner reads the pulse and tongue a page cannot. The period-pain page covers the patterns of painful menstruation in depth, and the menopause and perimenopause pages carry the patterns of the later transition; the emphasis here is the premenstrual phase itself.
The classic premenstrual picture: irritability and mood swings, breast and rib-side distension, a feeling of pressure that discharges as tension or tears, easing once the period flows. The direction is to soothe the Liver and move the Qi, and Xiao Yao San is the representative formula.
Liver Qi stagnation overwhelming a weaker Spleen: the same irritability with bloating, appetite changes and food cravings, loose stools, and fatigue before the period. The direction is to harmonize the Liver and strengthen the Spleen, which is the ground the Xiao Yao San family is built on.
A picture of depletion instead of stagnation: premenstrual fatigue, low mood, dull headaches, dizziness and light, pale flow. The direction is to tonify Qi and Blood, so a strong Qi-moving formula given into this picture can make it worse.
Symptoms weighted to the low back and reproductive core: premenstrual low back and knee soreness, low libido, and fluid retention. The direction is to supplement the Kidney instead of moving Qi alone.
Cautions
Extra restraintEverything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.
PMDD carries about seven times the odds of a suicide attempt (OR 6.97)
A 2021 systematic review and meta-analysis of studies assessing suicidality and premenstrual disturbance (13 studies, 10 in the meta-analysis) found women with PMDD had markedly higher odds of a suicide attempt (OR 6.97, 95% CI 2.98 to 16.29) and of suicidal ideation (OR 3.95, 95% CI 2.97 to 5.24) than women without premenstrual disturbance. Women with PMS also had raised odds of ideation. The authors recommend routine suicide-risk assessment for women with moderate-to-severe premenstrual disturbance and that treatment plans address suicidality directly.Prasad 2021, J Womens Health
Start slow, be smart, read the research, and consult a professional if you have any concerns. This is here to inform your choice, not make it for you.
When to See Someone
Most premenstrual symptoms are troublesome rather than dangerous, and much of what helps is in the sections above. These are the signs to bring to a professional, and urgently for the first one:
- Thoughts of harming yourself, or of suicide. The risk of these is higher in PMDD, and it is a reason to seek help now rather than to wait out the cycle. Self-harm is treatable, and help is available the same day through a crisis line or your doctor.(seek urgent care)
- Symptoms that do not clear after your period but run throughout the cycle. That pattern points to depression, anxiety or another condition that flares premenstrually rather than to PMS or PMDD, and it is treated differently.
- Symptoms severe enough to disrupt your work, studies or relationships. This is the level that defines PMDD, which is treatable, so it is a reason to get assessed rather than to cope alone.
- Bleeding that is new, heavy, prolonged, or coming at odd times, which has its own causes and deserves assessment in its own right.
- Severe symptoms that do not settle on first-line treatment, which is the point to be referred rather than to add another supplement.
None of this is meant to alarm you. Premenstrual symptoms are common and usually manageable with the steps above. The exceptions get their own section because one of them, the raised risk of self-harm in PMDD, is the specific harm this page exists to help you catch and act on early.
Common Questions
How do I know if it is PMS, PMDD, or something else?
Timing is the test, and charting is how you read it. True PMS and PMDD symptoms arrive in the luteal phase, the two weeks or so before a period, and clear soon after bleeding starts. PMDD is the severe, mood-dominated form and a DSM-5 diagnosis. Because memory of past cycles overstates symptoms, the diagnosis is confirmed by rating symptoms day by day across at least two cycles; standardized scoring of that record agrees with an expert diagnosis about 98% of the time. If the symptoms run throughout the cycle instead of lifting after the period, that points to depression, anxiety or another condition that flares premenstrually, which is treated on its own terms.
What is the most effective treatment for the mood symptoms?
An SSRI. SSRIs reduced premenstrual symptoms more than any other treatment measured. Pooled across 34 randomized trials, the efficacy estimate came from the trials that measured symptom relief (SMD -0.57 against placebo). They can be taken every day or only in the luteal phase, with continuous dosing working somewhat better. Cognitive behavioral therapy is a strong non-drug option whose benefit tends to last, and the drospirenone combined pill helps too, especially for a woman who also wants contraception. The three are sometimes combined.
Can I take the medication only in the two weeks before my period?
For an SSRI, yes. Luteal-phase dosing, taking the drug only in the second half of the cycle, works and keeps drug exposure and side effects lower than taking it every day. Continuous daily dosing has a slight edge on symptoms (SMD -0.69 against -0.39 for luteal-only), so the choice depends on how heavy the symptoms are and when they start. It is a decision to make with a prescriber.
Do supplements like chasteberry, calcium or evening primrose work?
They vary. Calcium at about 1200 mg a day is the best-supported, cutting symptoms 48% by the third cycle against 30% on placebo. Chasteberry has the most trial evidence of the botanicals for physical symptoms, though the trials are low quality, so the true effect is likely smaller than the pooled figure. Vitamin B6 helps modestly at up to 100 mg a day, and no higher, since larger doses can damage nerves. Evening primrose oil, popular as it is, did little in the best-controlled trials.
When is premenstrual mood an emergency?
When there are thoughts of harming yourself or of suicide. The risk of these is higher in PMDD, so severe premenstrual mood is a reason to seek help the same day through a crisis line or your doctor. Self-harm is treatable, and this is the one signal on this page that calls for urgent help.

This page is educational and it is not medical advice. Last reviewed and updated August 9, 2026.
Evidence strength
How confidently the research supports a claim. Strength describes the evidence, not our endorsement.
