Systematic review, 2024

What are the best treatments for PMDD and PMS?

SSRIs (antidepressants) and combined oral contraceptives (birth control pills) have the strongest evidence. For difficult cases, GnRH agonists and surgery work. Some alternatives like acupuncture and yoga show promise but need better quality research.

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.

Guideline, 2023

How are GnRH agonists used to treat PMDD that doesn't respond to standard medications?

GnRH agonists combined with hormone replacement are effective for severe PMDD that doesn't respond to first-line treatments, but many doctors don't know how to use this option.

Review, 2022

What causes severe PMS and what treatments work?

Severe PMS is caused by hormone changes and brain chemistry problems. Treatments that stop ovulation with hormones or increase serotonin with SSRIs both reduce symptoms.

Systematic review, 2022

What are the best treatments for PMDD and PMS?

SSRIs (antidepressants) and combined oral contraceptives (birth control pills) have the strongest evidence. For difficult cases, GnRH agonists and surgery work. Some alternatives like acupuncture and yoga show promise but need better quality research.

Review, 2018

What are the most effective treatments for premenstrual syndrome and PMDD?

Serotonin reuptake inhibitors and contraceptives with shortened or no hormone-free interval are the most effective treatments. Some women who do not respond may benefit from GnRH agonist treatment.

Review, 2018

Which women are most likely to experience hot flashes during menopause?

Up to 80% of women experience hot flashes during menopause, lasting about 10 years on average. Black and Hispanic women are more likely to experience them, while Asian women are less likely.

Study, 2015

What are the different types of premenstrual problems and how should they be diagnosed?

There are different types of premenstrual disorders, and doctors should use specific methods to diagnose PMS and distinguish it from other conditions.

Review, 2015

What do we know about PMS and PMDD and how are they treated?

PMS affects 30 to 40 percent of reproductive-age women and PMDD affects 3 to 8 percent. Serotonergic antidepressants are the most effective treatment, but oral contraceptives, lifestyle changes, cognitive behavioral therapy, and herbal supplements are also available options.

Randomised trial, 2012

Do hysterectomy or hormonal IUDs reduce premenstrual symptoms in women with heavy periods?

Both treatments significantly reduced premenstrual symptoms by 6 months with similar effectiveness. However, the study involved women treated for heavy periods, not those specifically diagnosed with PMS.

Survey study, 2011

Is premenstrual syndrome related to major depression?

Yes. Women with moderate to severe PMS are significantly more likely to have depression (11.3% to 24.6% depending on PMS severity). Women with both conditions are more severely impaired than those with either alone.

Randomised trial, 2010

What treatments work for premenstrual syndrome?

Several treatments reduce PMS symptoms according to controlled studies: SSRIs, some birth control pills, hormone injections, calcium, chasteberry, and cognitive-behavioral therapy. However, about 40% of women don't respond to current treatments.

Review, 2008

What hormonal treatments help PMS?

PMS appears to be caused by the body's sensitivity to progesterone after ovulation, though the exact cause is unknown. Treatment works by either stopping ovulation or reducing how sensitive the body is to progesterone.

Review, 2008

What medications are FDA-approved for treating PMDD?

Three selective serotonin reuptake inhibitors (SSRIs, a type of antidepressant) and a low-dose birth control pill containing drospirenone are FDA-approved for PMDD. SSRIs can be taken just during the two weeks before menstruation.

Systematic review, 2007

What treatments work for premenstrual syndrome?

Many treatments have been studied for PMS, but researchers face a major challenge: there is no standard way to measure symptom severity, making it difficult to know which treatments truly work.

Randomised trial, 2005

Does stopping ovulation help irritable bowel syndrome that gets worse during the menstrual cycle?

Yes, stopping ovulation with leuprolide acetate significantly improved bowel symptoms related to the menstrual cycle. Adding tibolone (a hormone) did not improve bowel symptoms further but did improve quality of life more than leuprolide alone.

Review, 2004

What is PMDD and how is it treated?

PMDD is a severe form of PMS with physical and behavioral symptoms during the second half of the menstrual cycle. Treatment starts with lifestyle changes and over-the-counter medications, and includes antidepressants if needed.

Review, 2004

How should doctors diagnose and treat PMS and PMDD?

Doctors can now diagnose these conditions using specific prospective symptom tracking and have several evidence-based treatments. Antidepressants that increase serotonin, especially when taken only during the luteal phase, work best for severe symptoms.

Systematic review, 2004

Do gonadotropin-releasing hormone injections work for premenstrual syndrome?

Yes, GnRH injections significantly improve PMS symptoms. Adding hormones does not reduce their effectiveness.

Randomised trial, 2003

What treatments work for PMS and PMDD?

Several treatments work. Non-drug options include cognitive behavioral therapy, exercise, and supplements like calcium and magnesium. Many studies support SSRIs (taken daily or only before menstruation). Hormonal treatments that stop ovulation also help.

Review, 2002

What treatments work best for PMS and PMDD?

Ovulation suppression and SSRIs (selective serotonin reuptake inhibitor antidepressants) are the two most effective treatments. SSRIs work particularly well for PMDD and can be taken only during the luteal phase of the cycle.

Review, 2001

What are PMS and PMDD, and how are they treated?

PMS is a cluster of symptoms occurring 7 to 14 days before menstruation. PMDD is the most severe form. Both should be treated first with lifestyle changes like exercise and stress management, with medication added if needed.

Randomised trial, 1997

Does tamoxifen or danazol help severe cyclical breast pain?

Yes. Both drugs reduced pain more than placebo during treatment, but tamoxifen was more effective and longer-lasting, with 53% still symptom-free 12 months after stopping.

Study, 1997

What medications work best for treating PMS?

SSRIs like fluoxetine and benzodiazepines like alprazolam have clear benefits for PMS. GnRH agonists also work well but cause too many side effects for routine use, and other drugs can treat specific symptoms like headaches or fluid retention.

Randomised trial, 1997

What is the difference between PMS and PMDD, and how should they be treated?

PMDD is a severe condition distinct from PMS that can be diagnosed using standardized criteria and daily symptom tracking for at least two menstrual cycles. Treatment options include lifestyle changes, SSRIs, or surgeries that stop ovulation, all proven effective in randomized trials.

Randomised trial, 1993

Does endometrial resection work as well as hysterectomy for heavy periods?

Endometrial resection was almost as satisfying as hysterectomy, with 84 out of 99 women satisfied versus 89 out of 95 with hysterectomy. However, hysterectomy was better for reducing premenstrual symptoms like painful periods, bloating, and breast tenderness.

Review, 1989

Are mental health conditions linked to the reproductive cycle?

Psychiatric disorders like PMS and postpartum depression are linked to the menstrual cycle and pregnancy. But research on PMS is still early and many questions remain.

Randomised trial, 1989

Does danazol help severe PMS symptoms?

Yes, most PMS symptoms improved more with danazol than placebo, though there were minor side effects. A double-blind controlled study provides good evidence.

Survey study, 2026

What are the causes, diagnosis, and treatments for PMS and PMDD?

This review consolidates what doctors know about PMS and PMDD. PMS affects 12-98% of reproductive-age women and PMDD affects 2-5%. Treatments range from lifestyle changes, therapy, and vitamins to medications like SSRIs and oral contraceptives.

Study, 2026

What treatments work for PMDD?

SSRIs (a type of antidepressant) and certain types of birth control are the main first-line treatments. New treatments targeting brain chemistry are being developed.

Cohort study, 2025

Do estrogen and progesterone each trigger PMDD symptoms differently?

Yes, likely. Both hormones triggered mood symptoms in women with PMDD when reintroduced after suppression, but progesterone appeared more closely linked to irritability and mood swings than estrogen.

Systematic review, 2025

Do drugs that stop ovulation help women with PMS?

The abstract is incomplete and does not provide the main results, so no clear answer can be determined from the information given.

Randomised trial, 2024

What causes PMS and PMDD and how are they treated?

PMS and PMDD happen when hormone changes interact with brain chemicals during the menstrual cycle. Treatments include birth control pills, progesterone, SSRIs (a type of antidepressant), and hormone injections for severe cases, though some treatments still need proof from rigorous trials.

Cohort study, 2022

What are PMS and PMDD and how should they be diagnosed and treated?

PMS involves 1-4 symptoms or 5 or more physical or behavioral symptoms. PMDD requires 5 or more symptoms with at least one mood symptom like irritability or mood swings. Treatments include exercise, cognitive behavioral therapy, and medications like SSRIs and hormonal contraceptives.

Randomised trial, 2020

Do steroid metabolites differ between women with PMDD and those without?

Yes. Women with PMDD show different patterns of certain steroid metabolites, particularly sulfated forms, which may relate to how their bodies process hormones.

Review, 2018

What treatments work for PMDD and severe premenstrual symptoms?

This review examines evidence for many treatments including antidepressants, hormonal therapy, cognitive behavioral therapy, lifestyle changes, and herbal remedies for PMDD. The review notes that many women with severe symptoms do not meet full PMDD criteria but still benefit from treatment.

Survey study, 2018

What causes irregular periods?

About 14.3% of Korean women aged 19-40 have irregular periods. Stress and depressive mood are the main causes, not medical conditions. Stress is the strongest factor.

Case-control study, 2017

Are PMDD symptoms triggered by changes in hormone levels or by having high hormone levels?

PMDD symptoms are triggered by the rapid increase in hormone levels after ovulation, not by having those hormones at steady high levels. Once hormone levels stay stable, symptoms improve.

Randomised trial, 2017

Do hormones process differently in women with PMDD?

Women with PMDD process certain sulfated steroid hormones differently than others, especially estradiol and DHEA metabolites. The study was very small and tested only women who were known to be hormone-sensitive, so the findings may not apply to all PMDD.

Cohort study, 2016

How often do doctors diagnose PMS and what treatments do they prescribe?

PMS diagnoses recorded in UK primary care fell dramatically from 8.43 per 1000 women in 1995 to 1.72 in 2013. Treatment shifted from progestogens and vitamin B6 to SSRIs and oral contraceptives.

Guideline, 2013

What do experts agree is the best way to treat PMS and PMDD?

A group of international experts agreed that treatment should start with careful diagnosis, and that the main options work either by calming brain serotonin activity or by stopping ovulation, with some other approaches worth more study.

Randomised trial, 2012

Is the stress hormone system different in women with premenstrual dysphoria?

The stress hormone system (HPA axis) functions normally in women with PMD, just like in women without it. This suggests PMD may have a different biological cause than depression. Progesterone increased stress hormones more than estradiol.

Review, 2012

Is PMDD a separate disease from PMS?

Yes. Research confirms PMDD is a discrete disorder with a good prognosis when appropriately diagnosed and treated.

Review, 2012

Is depression linked to hormonal changes during the menstrual cycle, pregnancy, and menopause?

Yes. Depression tied to hormonal changes appears in the same women across three life stages (premenstrual, after birth, and menopause). Transdermal estrogen patches may be more effective as first-line treatment than antidepressants.

Review, 2012

Does stopping ovulation help premenstrual symptoms?

Yes, transdermal estrogen (patch, gel, or implant) can stop the cyclical hormone changes that cause premenstrual symptoms. However, women usually need monthly progestogen and may experience side effects.

Randomised trial, 2009

Which hormone add-back therapy works best with GnRH agonist for PMDD?

The lowest dose of estradiol with progesterone worked better. The highest dose (1.5mg estradiol with 400mg progesterone) actually caused more symptom recurrence than lower doses or estradiol alone.

Case-control study, 2007

Are there genes that increase the risk of PMDD?

Genetic variations in the ESR1 gene (which codes for estrogen receptor alpha) appear linked to PMDD mood symptoms, suggesting genetic factors contribute to who develops the condition. This was found in a study of women with PMDD and unaffected controls.

Randomised trial, 2006

Do different types of PMS symptoms respond better to different medicines?

Yes. Different medications work best for different symptoms. SSRIs help irritability and anxiety. Birth control works broadly. Other drugs target specific symptoms. However, current treatments help fewer than 60% of women.

Review, 2006

What treatments work for premenstrual disorders?

Several treatments work. Three SSRIs are FDA-approved for PMDD. Exercise, diet changes, and therapy also help some women, but no single treatment works for everyone.

Review, 2005

Can controlling hormones during the luteal phase improve fertility treatment outcomes?

Yes. Lowering the hormone FSH during the luteal phase reduced size variation among egg follicles and improved their coordination during fertility treatment.

Cohort study, 2004

Does a premenstrual GnRH antagonist injection reduce variation in egg follicle sizes for fertility treatment?

Yes, in 25 women, a single premenstrual GnRH antagonist injection reduced the sizes of early egg follicles and the differences between them. This may help improve fertility treatment, though results are from a single center.

Study, 2003

Does the stress response system work differently in women with PMS across the menstrual cycle?

Women with PMS failed to show the normal increased stress hormone response during the luteal phase that women without PMS show. Progesterone, not estrogen, appears to control this stress response.

Survey study, 2003

Does migraine risk change during menopause in women with PMS?

Yes. In women with PMS, migraine is highest in late perimenopause at 31% and lowest after menopause at 7%. Hormone levels also affect migraine risk.

Review, 2003

What treatments work best for PMS and PMDD?

There is no single best treatment. For mild PMS, lifestyle changes help. For moderate symptoms, selective serotonin reuptake inhibitors (SSRIs) like fluoxetine and sertraline are most effective. Calcium and evening primrose oil may offer modest benefit.

Randomised trial, 2003

Does leptin explain why women develop PMS symptoms?

Probably not. Leptin levels did not change with successful PMS treatment, so leptin may not be the cause of PMS.

Review, 2003

What role do hormones play in PMS and how should we treat it?

Female hormones trigger PMS by affecting brain chemistry, especially the serotonin and GABA systems. SSRIs and medications that stop ovulation are the most effective treatments.

Randomised trial, 2002

What treatments work best for cyclical breast pain?

Initial treatments like reassurance, proper bra fit, reducing caffeine, and primrose oil should be tried first. Medications like danazol work but often cause side effects.

Review, 2002

What drugs work for PMDD?

Serotonin-based antidepressants, especially SSRIs taken only during the luteal phase, are the first-line treatment for PMDD. Progesterone is not effective.

Review, 2002

What treatments work for PMDD?

PMDD affects 2 to 10 percent of women of reproductive age. Try lifestyle changes first, and if that does not work, SSRIs taken just during the luteal phase are very effective with minimal side effects.

Study, 2002

Does a protein called IL-6 in the uterus change throughout the menstrual cycle?

Yes. IL-6 levels in the uterus are low in the first half of the cycle and increase 5 to 10 times in the second half, especially around the time for pregnancy implantation and before the period.
