PMDD — premenstrual dysphoric disorder

What PMDD is — and isn’t

Premenstrual dysphoric disorder is a severe form of premenstrual symptoms that shows up in the week or two before your period and lifts within a few days of it starting. It’s recognized in the DSM-5 as its own diagnosis — not just “bad PMS.”

Common symptoms during the luteal phase include:

• Sudden mood crashes — feeling deeply sad, hopeless, or tearful for no clear reason
• Irritability or anger that feels out of proportion
• Anxiety, tension, feeling on edge
• Brain fog, difficulty concentrating, memory issues
• Loss of interest in things you normally enjoy
• Feeling overwhelmed or out of control
• Sleep disruption, fatigue, appetite changes, food cravings
• Physical symptoms — bloating, breast tenderness, headaches

The hallmark is the timing: symptoms cluster predictably in the luteal phase (after ovulation, before menstruation), and meaningfully improve once your period starts. If your mood symptoms run all month, this might be something other than PMDD — we’ll figure that out together.

Why it gets missed

PMDD is often dismissed as “just PMS” by patients and providers alike. The reality: a meaningful percentage of menstruating people experience PMDD, and it can derail relationships, work, and self-image for years before being correctly identified. Many patients have been told their mood swings are a personality flaw — they’re not.

How we treat PMDD

SSRIs

Selective serotonin reuptake inhibitors are the most studied medication treatment for PMDD. Two evidence-based dosing strategies:

• Continuous dosing — taken every day. Effective and simple to follow.
• Luteal-phase dosing — only during the symptomatic two weeks. Works because SSRIs reduce PMDD symptoms much faster than they reduce regular depression. Lower side-effect burden, especially for sexual side effects.

We’ll talk through which approach makes sense based on how predictable your cycle is and your preferences.

Hormonal options

Some hormonal contraceptives — particularly drospirenone-containing combined oral contraceptives taken continuously — have evidence for PMDD. We’ll coordinate with your OB/GYN if hormonal treatment makes sense.

CBT and lifestyle

Cognitive-behavioral therapy adapted for PMDD — including symptom tracking, scheduling, and coping skills around the high-symptom window — is meaningfully helpful. Sleep stability, regular exercise, and reducing alcohol around the luteal phase all add up.

What the first visit looks like

We’ll review your cycle history, ask you to track symptoms across one to two cycles to confirm the pattern, and rule out conditions that can mimic or co-occur with PMDD (depression, anxiety, thyroid issues). Then we’ll build a treatment plan together — including whether medication, therapy, or both makes sense.
