Treatment of Severe PMDD

For severe premenstrual dysphoric disorder (PMDD), selective serotonin reuptake inhibitors (SSRIs) are the first-line treatment, with sertraline 50-150 mg/day being the most strongly recommended option based on FDA approval and extensive evidence. 1, 2, 3

First-Line Pharmacologic Treatment: SSRIs

Recommended SSRI Regimens

Sertraline is FDA-approved specifically for PMDD and should be initiated at 50 mg once daily, with dose adjustments up to 150 mg/day based on response. 1 The medication can be administered either:

  • Continuous daily dosing throughout the menstrual cycle (50-150 mg/day) 1
  • Luteal phase dosing (50-100 mg/day starting 14 days before expected menses) 1, 4, 5

Luteal phase or intermittent dosing is equally effective as continuous dosing and reduces medication exposure, cost, and long-term side effects. 4, 5 This approach allows treatment for only 14 days per month while maintaining efficacy for psychological, behavioral, and physical symptoms. 4

Alternative SSRIs if Sertraline Fails

If sertraline is ineffective or not tolerated, switch to another SSRI: 2, 3, 5

  • Fluoxetine 10-20 mg/day 2
  • Escitalopram 10-20 mg/day 2
  • Paroxetine 12.5-25 mg/day 2
  • Citalopram (standard dosing) 5

All SSRIs demonstrate significant improvement in emotional, cognitive-behavioral, and physical symptoms, with particular efficacy for psychological symptoms. 4, 5

Second-Line Treatment: Combined Hormonal Contraceptives

If SSRIs are contraindicated, ineffective, or the patient desires contraception, use drospirenone 3 mg/ethinyl estradiol 20 mcg in a 24/4 extended cycle regimen. 2, 6 This specific formulation has demonstrated significant improvement in both emotional and physical PMDD symptoms. 6

Critical Contraceptive Counseling Points

  • Avoid progestin-only methods (progestin-only pills, levonorgestrel IUD, etonorgestrel implant, depot medroxyprogesterone acetate) as they can worsen mood symptoms in PMDD patients 6
  • Copper IUDs are recommended for patients seeking non-hormonal contraception 6
  • Other monophasic, extended-cycle combined hormonal contraceptives with less androgenic progestins may be helpful but lack robust evidence 6

Third-Line Options for Treatment-Resistant Cases

If both SSRIs and hormonal contraceptives fail: 3, 5

  • Venlafaxine (SNRI with serotonergic activity) 3
  • Duloxetine (SNRI) 3
  • Alprazolam (low-dose, intermittent luteal phase dosing only as second-line) 3, 5
  • Buspirone 3

For severe refractory cases, consider short-term trials of GnRH agonists or danazol, but these are limited by serious side effects and cost, restricting use to brief periods only. 5

Adjunctive Non-Pharmacologic Treatment

Cognitive Behavioral Therapy (CBT) demonstrates effectiveness in reducing functional impairment, depressed mood, anxiety, mood swings, irritability, and symptom severity. 2 CBT can be used:

  • As monotherapy for patients refusing medication 2
  • In combination with SSRIs for enhanced response 2
  • To address residual symptoms after pharmacologic treatment 2

Calcium supplementation (1200 mg/day) is the only supplement with consistent therapeutic benefit and should be recommended as adjunctive treatment. 3

Common Pitfalls to Avoid

  • Do not use progestin-only contraceptives in PMDD patients, as progesterone exposure triggers symptoms 6
  • Do not cap SSRI doses below therapeutic range—full FDA-approved dosing is necessary for efficacy 1
  • Do not confuse PMS with PMDD—PMDD requires moderate-to-severe symptoms causing significant functional impairment per DSM-5 criteria 2
  • Monitor for SSRI side effects: headache, fatigue, insomnia, anxiety, and sexual dysfunction are commonly reported 4
  • Ensure symptom timing is documented—symptoms must occur during the luteal phase and resolve with menses onset 2, 5

Treatment Algorithm Summary

  1. Start sertraline 50 mg/day (continuous or luteal phase dosing) 1, 2
  2. If inadequate response after 2-3 cycles, increase to 100-150 mg/day 1
  3. If sertraline fails, switch to alternative SSRI (fluoxetine, escitalopram, paroxetine) 2, 5
  4. If SSRIs ineffective or contraindicated, use drospirenone/ethinyl estradiol 24/4 regimen 2, 6
  5. Consider CBT as monotherapy or adjunct throughout treatment 2
  6. Add calcium supplementation 1200 mg/day 3
  7. For refractory cases, trial venlafaxine, duloxetine, or low-dose luteal alprazolam 3, 5
