Guideline, 2019

How should doctors treat PMS and PMDD?

Treatment should be tailored to each woman's symptoms and life stage. Options include therapy, herbs, antidepressants, birth control to stop ovulation, and water pills.

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.

Systematic review, 2013

Does Vitex (chaste tree) help PMS and PMDD symptoms?

Most studies found Vitex better than placebo for PMS. For PMDD, results were mixed: one study showed it equal to fluoxetine, while another found fluoxetine more effective. Side effects were mild.

Randomised trial, 2008

Does drospirenone with ethinyl estradiol birth control help PMDD?

This birth control formulation is the only hormone-based option with large randomized controlled trials proving it works for PMDD and has FDA approval for this use.

Systematic review, 2008

What treatments work best for PMS and PMDD?

Antidepressants called SSRIs are proven effective for severe PMDD and are the first medication to try. Lifestyle changes and exercise are recommended for all women with PMS or PMDD.

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, 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.

Study, 2002

Which PMS treatments have good scientific evidence?

Calcium at 1200 mg daily and certain antidepressants have good evidence of working. Many popular treatments like vitamin B6, evening primrose oil, and birth control pills lack strong evidence. Some treatments like progesterone do not work.

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.

Review, 1999

Does vitamin B6 supplement help treat PMS symptoms?

Yes, vitamin B6 is beneficial for treating premenstrual syndrome according to a systematic review of published studies. However, the abstract does not provide specific details about the magnitude of benefit.

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, 1995

Does spironolactone help PMS symptoms?

Yes. Spironolactone significantly reduced mood symptoms like irritability and depression, and physical symptoms like breast tenderness and bloating, compared to placebo.

Randomised trial, 1983

Is bromocriptine effective for premenstrual syndrome?

No substantial evidence that bromocriptine works for premenstrual syndrome overall. It may help breast pain if the dose is at least 5 mg daily.

Randomised trial, 2025

How do leptin levels and combined medical treatments affect premenstrual symptoms in obese women?

Obese women with premenstrual tension syndrome had higher leptin levels and nervousness than healthy women. Combined treatments including diet, exercise, and medication significantly reduced both leptin levels and nervousness.

Survey study, 2025

How common are PMS and painful periods among female medical students in Saudi Arabia, and what causes them?

Both are very common - 78.33% have PMS and 75.67% have painful periods. Young age, not being married, stress, fatty foods, and coffee drinking increase the risk.

Randomised trial, 2024

Do hormonal changes in obese women cause worse PMS, and can medications help?

Yes, obese women with PMS had significantly higher stress hormone levels than healthy women, and a combination treatment of medications, diet, and exercise significantly reduced these hormones and PMS symptoms.

Randomised trial, 2023

Does gamma-tocopherol (a form of vitamin E) reduce premenstrual syndrome symptoms?

Yes. Gamma-tocopherol significantly reduced fatigue and anger, and also reduced leg swelling. Because this was a well-designed controlled trial where each woman tried both treatments, we can be fairly confident about these effects.

Survey study, 2020

Do women with hidradenitis suppurativa experience flares around their menstrual period?

Yes, about 6 in 10 women report this skin condition worsening around their period, and most of those experience flares in the week before menstruation. Some hormonal treatments helped but others made symptoms worse.

Randomised trial, 2020

Does saffron reduce PMS symptoms as well as fluoxetine?

Yes, saffron reduced PMS symptoms similarly to fluoxetine and may even be better for breast and abdominal pain with potentially fewer side effects.

Guideline, 2017

How should premenstrual disorders be managed?

There is no single best treatment. Treatment options include cognitive behavioral therapy, alternative therapy, antidepressants, ovulation suppression, and diuretics. The choice depends on symptoms, age, family plans, health, and preferences.

Randomised trial, 2014

Is chamomile as effective as mefenamic acid for breast pain associated with PMS?

Yes. Chamomile appeared to be similarly effective as mefenamic acid (a standard pain medicine) at reducing the intensity of breast pain associated with PMS.

Randomised trial, 2014

Is chamomile extract more effective than mefenamic acid for premenstrual syndrome?

Yes, for emotional symptoms. Chamomile reduced emotional symptoms by about 30 to 33 percent while mefenamic acid reduced them by about 11 percent.

Study, 2012

Does combining two medications treat PMS symptoms better than each one alone?

Yes, the study found that combining mefenamic acid with sulbutiamine worked better than either medication by itself, with 66.87% symptom improvement for the combination versus 39.33% for mefenamic acid alone and 41.01% for sulbutiamine alone.

Randomised trial, 2011

Does sumatriptan-naproxen help women with period migraines and period pain function better?

Yes, women given the combination drug reported higher satisfaction, better work productivity, and less functional disability compared to placebo at 24 hours.

Randomised trial, 2010

Which works better for premenstrual breast pain, cabergoline or bromocriptine?

Both drugs reduced breast pain equally well, with about two-thirds of women in each group responding. Cabergoline caused far fewer side effects.

Randomised trial, 2010

Do birth control pills with drospirenone help PMDD?

Birth control pills containing drospirenone in a 24/4 formulation appear to help both physical and mood symptoms of PMDD based on randomized trials. However, because placebo effects were strong, more research is needed to confirm how much improvement comes from the drug itself.

Randomised trial, 2007

Does drospirenone/ethinylestradiol birth control help PMDD symptoms?

Yes. This specific birth control pill significantly improved PMDD symptoms over three cycles and improved acne over six cycles while providing 99% contraceptive protection over one year.

Randomised trial, 2007

Does bromocriptine or pyridoxine help reduce PMS symptoms?

Both bromocriptine and pyridoxine significantly reduced PMS symptoms over 3 months. Pyridoxine showed a higher response rate with fewer side effects.

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

How common is PMS in teenagers and how should it be treated?

An estimated 60-80% of menstruating teenagers experience some premenstrual symptoms. Those with moderate to severe symptoms that disrupt their lives meet criteria for PMS or PMDD. Treatment begins with education and lifestyle changes.

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, 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.

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.

Randomised trial, 2001

Does an oral contraceptive with drospirenone and ethinyl estradiol treat PMDD?

The birth control pill showed signs of helping, especially with appetite, acne, and food cravings. However, most improvements were not statistically significant, and the study had limitations.

Randomised trial, 2000

What non-antidepressant treatments might help PMS?

A study of 466 women found calcium was effective at reducing emotional, behavioral, and physical PMS symptoms. Cognitive therapy, light therapy, and tryptophan also showed promise in early trials.

Review, 1993

What are the medication options for treating PMS?

PMS can be treated with hormonal medications that alter the menstrual cycle, mood drugs, diuretics for fluid retention, and pain relievers for headaches. Treatment should start with simpler measures and consider side effects.

Randomised trial, 1992

Does bromocriptine help premenstrual syndrome?

Bromocriptine helped significantly with physical symptoms like abdominal tension, water retention, weight gain, and breast tenderness. It was less clear whether it helped with mood symptoms like depression and irritability.

Non-randomised trial, 1991

Does mefenamic acid help PMS symptoms?

Yes. A randomized double blind trial of 15 women found that mefenamic acid 500 mg three times daily reduced irritability, anxiety, abdominal swelling, and headaches compared with placebo.

Randomised trial, 1991

Do spironolactone and medroxyprogesterone acetate help premenstrual tension?

Yes, both medications significantly reduced symptoms compared to placebo. However, placebo itself also significantly improved symptoms, which is important to know.

Review, 1990

How common is PMS and what are the best ways to treat it?

PMS is common among women of reproductive age, especially in their 30s or older. Treatment can include exercise, diet, vitamins, and medications such as progesterone or birth control pills, with support and counseling being especially important.

Review, 1990

What treatments for PMS actually work?

Most PMS treatments are based on weak research. The most effective approach involves accurate diagnosis, stress control, a healthy diet and exercise, and possibly the medication alprazolam. Progesterone has been shown not to work.

Survey study, 1990

What do we know about what causes PMS and how common it is?

A literature review found PMS affects 30 to 40% of women, especially those who work outside the home, have had multiple children, or use alcohol. Many theories about causes exist, but none are proven.

Randomised trial, 1989

Does naproxen sodium help premenstrual symptoms?

Yes. Naproxen sodium reduced premenstrual and menstrual pain much more effectively than placebo. It also improved behavioral symptoms, likely because pain relief helped women function better.

Survey study, 1989

What does research say about what causes PMS and what treatments work?

A review of PMS research found no definitive cause and no universally effective treatment. Lifestyle approaches like diet, exercise, and support help many women, while some medications like alprazolam and mefenamic acid help some, but progesterone therapy is ineffective.

Randomised trial, 1988

What causes PMS and what are the treatment options?

The cause of PMS remains unknown, though leading theories involve prostaglandins, endorphins, or progesterone deficiency. Treatments include education, diet, exercise, and various medications. Most people with PMS can be helped.

Randomised trial, 1987

Does spironolactone help premenstrual syndrome symptoms?

Spironolactone was significantly better than placebo for bloatedness only. No significant improvement was seen for other symptoms, weight, blood pressure or other complaints.

Review, 1986

How should breast pain from PMS be treated?

Breast pain is part of PMS. Many treatments exist but we do not have clear evidence about which ones work.

Randomised trial, 1986

Does mefenamic acid help premenstrual syndrome symptoms?

Mefenamic acid showed overall improvement compared to placebo. However, it did not clearly help individual symptoms, except for gastrointestinal symptoms.

Randomised trial, 1984

Does mefenamic acid help premenstrual tension?

Yes. 86 percent of women reported significant relief of premenstrual tension with mefenamic acid, and the drug appears to work by lowering prostaglandin levels.

Randomised trial, 1983

Does bromocriptine help severe premenstrual tension?

No, bromocriptine did not work better than placebo. Most women improved on both (80% on placebo, 50-88% on bromocriptine), suggesting the improvement may not be from the medication itself.

Randomised trial, 1982

Is bromocriptine or norethisterone more effective for premenstrual syndrome?

Bromocriptine reduced breast engorgement, irritability, and total symptoms more than placebo, while norethisterone only helped breast tenderness. Bromocriptine worked better but had more side effects.

Randomised trial, 1982

Does lowering prolactin with bromocriptine help premenstrual syndrome?

No. Although bromocriptine lowered prolactin, it was not significantly more effective than placebo. This suggests prolactin alone doesn't cause premenstrual syndrome.

Randomised trial, 1980

Does bromocriptine help premenstrual tension?

Bromocriptine improved breast tenderness, bloating, and depression, but placebo also helped with many other symptoms, so the true effect may be smaller than it appears.

Randomised trial, 1980

Does mefenamic acid help premenstrual symptoms?

Yes, mefenamic acid significantly improved premenstrual tension, irritability, depression, pain and headache, but was not effective for breast symptoms.

Study, 1979

Does dydrogesterone or pyridoxine work better for premenstrual syndrome?

Dydrogesterone worked for 70% of women with premenstrual syndrome, while pyridoxine worked for 55%. At least 3 months of treatment is needed to see if either helps.

Study, 1978

Do women with premenstrual tension have too much water in their bodies?

Women with premenstrual tension had normal total body water, but showed an imbalance between water and potassium during the late menstrual phase. Diuretics and bromocriptine did not help.

Randomised trial, 1977

Does bromocriptine help premenstrual syndrome?

Bromocriptine improved all PMS symptoms but was significantly better than placebo only for breast pain. This is a small study from 1977, so we can have only moderate confidence.

Study, 1975

Does suppressing prolactin affect how the menstrual cycle works?

No clear difference was found. When prolactin was suppressed to low levels, the menstrual cycle continued with the same pattern of hormonal changes.
