Best Treatment for Premenstrual Dysphoric Disorder (PMDD)
Selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment for PMDD, with continuous dosing demonstrating superior efficacy compared to luteal-phase-only administration. 1
First-Line Pharmacologic Treatment: SSRIs
SSRIs reduce overall premenstrual symptoms with a standardized mean difference of -0.57 (moderate-certainty evidence), and continuous administration is more effective than luteal-phase dosing (SMD -0.69 vs -0.39, p=0.03). 1
Recommended SSRI Regimens
The following SSRIs have established efficacy for PMDD 2, 3, 4:
- Sertraline 50–150 mg daily 3
- Fluoxetine 10–20 mg daily 3, 4
- Escitalopram 10–20 mg daily 3
- Paroxetine 12.5–25 mg daily 3
- Citalopram (effective in trials) 4
Continuous daily dosing is preferred over luteal-phase-only administration because it produces greater symptom reduction, though luteal-phase dosing (starting 14 days before menses) remains an acceptable alternative for patients concerned about long-term medication use or cost. 1, 4, 5
SSRI Adverse Effects to Counsel Patients About
Common side effects include (all moderate-certainty evidence unless noted) 1:
- Nausea (OR 3.30) – most common
- Sexual dysfunction or decreased libido (OR 2.32)
- Insomnia (OR 1.99)
- Asthenia/decreased energy (OR 3.28)
- Somnolence/decreased concentration (OR 3.26, low-certainty evidence)
- Dizziness (OR 1.96)
- Dry mouth (OR 2.70)
- Diarrhea (OR 2.06)
- Sweating (OR 2.17)
- Tremor (OR 5.38)
Second-Line Hormonal Treatment: Drospirenone-Containing Oral Contraceptives
If SSRIs are ineffective, contraindicated, or not tolerated, drospirenone 3 mg combined with ethinyl estradiol 20 mcg (24 days active pills, 4 days inactive) is an FDA-approved option for PMDD. 6, 3
Two randomized controlled trials demonstrated that drospirenone/ethinyl estradiol significantly improved Daily Record of Severity of Problems scores compared to placebo (average decrease 37.5 points vs 30.0 points). 6
Critical Contraindication
Depot medroxyprogesterone acetate (DMPA) should be avoided in PMDD because it may exacerbate mood symptoms and negatively impact bone mineral density. 7
Third-Line and Alternative Treatments
If first-line and second-line treatments fail 2, 4, 5:
Other Psychiatric Medications
- Venlafaxine (SNRI) – demonstrated efficacy 2
- Duloxetine (SNRI) – demonstrated efficacy 2
- Alprazolam (low-dose, luteal-phase only) – second-line option, use cautiously due to dependence risk 2, 4
- Buspirone – demonstrated efficacy 2
Anovulatory Treatments (Specialist Referral)
- GnRH agonists (e.g., leuprolide) – reserve for refractory cases due to cost and side effects (requires add-back estrogen/progestin therapy) 4, 5
- Danazol – reserve for refractory cases due to androgenic side effects 4
Evidence-Based Supplements
- Calcium supplementation (1200 mg daily) – only supplement with consistent therapeutic benefit 2, 5
- Chasteberry (Vitex agnus-castus) – may be useful adjunct 5
- St. John's Wort (Hypericum perforatum) – may be useful adjunct 5
Psychotherapeutic Treatment
Cognitive behavioral therapy (CBT) reduces functional impairment, depressed mood, anxiety, mood swings, irritability, insomnia, interpersonal conflict, and symptom severity in PMDD. 3
CBT can be offered as monotherapy for patients who decline pharmacotherapy or as adjunctive treatment alongside SSRIs. 3, 5
Treatment Algorithm
Start with continuous SSRI (sertraline 50–150 mg, fluoxetine 10–20 mg, escitalopram 10–20 mg, or paroxetine 12.5–25 mg daily) 1, 3
If inadequate response after 2–3 menstrual cycles, switch to a different SSRI 2, 4
If second SSRI fails, consider:
If all above fail, refer to gynecology or psychiatry for:
Common Pitfalls to Avoid
- Do not prescribe depot medroxyprogesterone acetate (Depo-Provera) – it worsens PMDD symptoms 7
- Do not assume all oral contraceptives are equivalent – only drospirenone-containing formulations have proven PMDD efficacy 6, 3
- Do not delay SSRI trial – SSRIs work rapidly in PMDD (often within 1–2 cycles), unlike their delayed onset in major depression 4, 5
- Do not require daily SSRI dosing if patient prefers intermittent – luteal-phase dosing is effective and may improve adherence 1, 4, 5
- Do not overlook CBT – it addresses functional impairment and can be combined with medication 3
