PMDD: Symptoms, Diagnosis and Treatment of Premenstrual Dysphoric Disorder

By the Find Her Doctor editorial team · Updated November 1, 2026 · 5 min read

PMDD (premenstrual dysphoric disorder) is a severe, cyclical condition that brings intense mood symptoms, like depression, irritability, anxiety and mood swings, in the week or two before your period. Symptoms ease within a few days after bleeding starts. It's treatable with antidepressants called SSRIs, certain birth control pills and other approaches.

People with PMDD often describe it as becoming a different person for part of every month: snapping at a partner, crying at work, feeling hopeless, then waking up a few days into their period and feeling like themselves again. It is not "just bad PMS," and you don't have to white-knuckle through it.

If you're having thoughts of harming yourself, call or text 988 to reach the 988 Suicide & Crisis Lifeline, or call 911.

Is it PMS or PMDD?

A rough gut check: if your partner, roommate or coworkers can predict your period by your mood, and you dread that week every month, it's worth an evaluation.

What causes it?

PMDD isn't caused by abnormal hormone levels. Experts believe people with PMDD have an unusual sensitivity in the brain to the normal rise and fall of estrogen and progesterone during the cycle. Changes in serotonin, a brain chemical that affects mood, appear to be involved. Genetics may contribute.

You may be more likely to have PMDD with a personal or family history of depression or other mood disorders, or a history of trauma.

The symptoms

Symptoms start in the luteal phase, the stretch between ovulation and your period, and improve within a few days after bleeding starts. They're minimal or gone in the week after your period.

Mood

• Marked irritability or anger, or more conflict with people
• Depressed mood, hopelessness or harsh self-criticism
• Anxiety or tension, feeling keyed up or on edge
• Mood swings, sudden sadness or sensitivity to rejection

Everything else

• Less interest in usual activities
• Trouble concentrating
• Fatigue or low energy
• Appetite changes, overeating or cravings
• Sleeping too much or too little
• Feeling overwhelmed or out of control
• Physical symptoms like breast tenderness, bloating, joint or muscle pain, or weight gain

Some people with PMDD have thoughts of self-harm or suicide in the days before their period. That's a symptom, it's treatable, and it's a reason to reach out now, not after the next cycle.

How it's diagnosed

There's no blood or imaging test. Diagnosis is based on the pattern over time.

Step 1: track every day for two cycles

Your clinician will likely ask you to track symptoms daily for at least two menstrual cycles. Use a paper chart, a validated tool like the Daily Record of Severity of Problems, or an app. Each day, note:

• Each symptom and how bad it is
• The first day of each period

It feels tedious, and it's the single most useful thing you can bring to the appointment. Many people are surprised to see how sharply the pattern lines up once it's on paper.

Step 2: check the criteria

Under the DSM-5-TR, PMDD requires:

• At least five symptoms in the week before your period, including at least one core mood symptom (irritability, depressed mood, anxiety or mood swings)
• Symptoms that improve within a few days after your period starts and become minimal in the week after
• Symptoms in most menstrual cycles over the past year
• Symptoms that cause significant distress or interfere with daily life

Step 3: rule out look-alikes

The next step is checking whether something else explains your symptoms, such as:

• Depression or anxiety that's present all month but worse before your period (premenstrual exacerbation)
• Thyroid disease
• Perimenopause
• Bipolar disorder

Treatment options

Many people end up combining treatments. It can take a couple of tries to find the right fit.

SSRIs

SSRIs are first-line treatment for PMDD, and they often work faster for PMDD than for depression, sometimes within the same cycle. Your clinician may suggest taking one:

• Every day, or
• Only during the luteal phase (the two weeks before your period), or
• Daily, with a higher dose before your period

The medicine and dose are chosen for you individually. A common worry is "Does taking an antidepressant mean I'm depressed?" No. For PMDD, it's treating a specific brain response to your cycle.

Hormonal treatment

• Combined oral contraceptives, especially a pill containing drospirenone and ethinyl estradiol, which is FDA-approved for PMDD. Taking pills continuously to skip periods may help some people. Other hormonal methods can help or worsen symptoms, depending on the person.
• GnRH agonists, which temporarily stop the menstrual cycle, are sometimes used for severe PMDD that hasn't responded to other treatment, usually with add-back hormones.

Therapy and habits

• Cognitive behavioral therapy (CBT) helps with coping and mood symptoms.
• Regular exercise, enough sleep and stress management may ease symptoms.
• Less caffeine, alcohol and salt helps some people, though evidence is limited.
• Calcium has some evidence for premenstrual symptoms. Ask before starting supplements.

Surgery, as a last resort

For a small number of people with severe PMDD that hasn't responded to anything else, removing the ovaries (usually with hysterectomy) is a last-resort option. It causes surgical menopause and is generally considered only after a successful trial of a GnRH agonist.

Living with it

While treatment kicks in:

• Plan around your cycle. Put big presentations, hard conversations and packed weekends in your good weeks when you can.
• Tell the people close to you. A simple "the week before my period is hard, and it's a medical thing" can lower conflict.
• Have a plan for hard days: extra rest, time alone, a person to text.
• Keep tracking so you can see whether treatment is working.

PMDD symptoms are tied to the menstrual cycle, so they typically stop after menopause. They can get worse during perimenopause when hormones swing.

When to see a doctor

Make an appointment with a gynecologist, primary care clinician or mental health professional if:

• Mood changes before your period strain your relationships, work or school
• You feel hopeless, anxious or out of control in the days before your period
• PMS symptoms haven't improved with lifestyle changes
• Symptoms are getting worse, including during perimenopause

Get help right away if you have thoughts of suicide or self-harm. Call or text 988, or call 911. In New York City, 988 also connects you to local crisis services.
