Mood shifts that track your cycle are a pattern, not a personality flaw.
If you have thoughts of harming yourself, contact your local emergency services or a crisis line now. PMDD is treatable — don't start, stop or change any medication based on general information; do it with a clinician.
Approaches a clinician may discuss
SSRIs
Certain antidepressants (SSRIs) are a first-line treatment for PMDD and often work faster than they do for depression. Some people take them only in the luteal phase (the two weeks before a period); others take them continuously. A clinician tailors this.
Hormonal options
Some combined hormonal contraceptives — particular formulations, sometimes taken continuously — can help by smoothing the hormonal swings that trigger PMDD. What suits you depends on your history.
CBT and psychological support
Cognitive behavioural therapy has evidence for PMDD and can be used alongside or instead of medication. It gives practical tools for the luteal-phase weeks.
Lifestyle and self-management
Sleep, exercise, reducing alcohol, and planning demanding tasks around your cycle won't 'cure' PMDD but can take the edge off and support other treatments. Tracking shows you what genuinely helps you rather than in general.
When symptoms are severe
For severe, treatment-resistant PMDD, specialists may discuss further options. If PMDD is seriously affecting your life, ask for referral — you don't have to have exhausted everything first.
Why tracking guides treatment
Because PMDD treatment is often trial-and-adjust, a dated symptom log across cycles is how you and your clinician tell whether something is working. It turns 'I think it's a bit better' into evidence.
Common questions
- What's usually tried first for PMDD?
- SSRIs and certain hormonal (combined pill) approaches are common first-line options, often alongside CBT and lifestyle support. The choice depends on your symptoms, preferences and medical history — it's a clinician-led decision.
- How long before I know if a treatment works?
- It varies, but because PMDD is cycle-linked, clinicians usually look across a couple of cycles to judge. Tracking your symptoms each cycle is what makes that judgement reliable.
- Can I treat PMDD without medication?
- Some people manage with CBT and lifestyle approaches, especially for milder PMDD. Others need medication. There's no single right answer — it's about what works for you, discussed with a clinician.
