Best Birth Control for Heavy Periods

Combined oral contraceptives containing 30-35 μg ethinyl estradiol with levonorgestrel or norgestimate are the recommended first-line treatment for heavy menstrual bleeding when contraception is also desired. 1

First-Line Hormonal Treatment

Start with a monophasic combined oral contraceptive (COC) containing 30-35 μg ethinyl estradiol combined with levonorgestrel or norgestimate. 1, 2 This formulation:

  • Reduces menstrual blood loss by inducing regular shedding of a thinner endometrium 1
  • Decreases menstrual cramping 2
  • Provides additional benefits including acne improvement and reduced risk of endometrial and ovarian cancers 1, 2

Practical Implementation

  • No backup contraception is needed if started within the first 5 days of menstrual bleeding 2
  • If started more than 5 days after bleeding onset, use backup contraception (condoms) for 7 days 2
  • Counsel patients that irregular bleeding during the first 3-6 months is common, generally not harmful, and typically resolves with continued use 1, 2

Managing Breakthrough Bleeding

If heavy or prolonged bleeding persists despite COC therapy:

  • Add NSAIDs (mefenamic acid 500 mg three times daily, or ibuprofen) for 5-7 days during bleeding episodes, which reduces menstrual blood loss by 20-60% acutely 1
  • For extended/continuous COC regimens, consider a 3-4 day hormone-free interval (but never during the first 21 days of use and not more than once per month) 1, 2
  • Rule out pregnancy, sexually transmitted infections, medication interactions, or new uterine pathology (polyps, fibroids) before treating breakthrough bleeding 2

Superior Alternative: Levonorgestrel-Releasing Intrauterine System (LNG-IUS)

The LNG-IUS is the most effective medical treatment for heavy menstrual bleeding, reducing blood loss by 71-95%, which is superior to all oral medications. 3, 4, 5

When to Choose LNG-IUS Over COCs

The LNG-IUS should be strongly considered when:

  • Estrogen-containing contraceptives are contraindicated (hypertension, history of thromboembolism, migraine with aura, smoking over age 35) 3
  • Oral medication adherence is a concern 6
  • Maximum reduction in menstrual blood loss is the priority 4, 7
  • Long-term contraception (5-7 years) is desired 6

LNG-IUS Benefits

  • Achieves 71-95% reduction in menstrual blood loss, comparable to endometrial ablation 3, 4, 5
  • Improves anemia markers 3
  • Minimal systemic hormonal absorption, avoiding blood pressure elevation 3
  • More cost-effective than endometrial ablation or hysterectomy 4, 5
  • Improves quality of life comparably to surgical options 5

LNG-IUS Counseling Points

  • Irregular bleeding or spotting is common during the first 3-6 months after insertion but typically resolves 3, 6
  • Many women develop amenorrhea after 6-12 months, which is beneficial for heavy bleeding and not harmful 6, 8
  • Enhanced pre-insertion counseling about expected bleeding patterns markedly reduces premature removal and increases satisfaction 6
  • Backup contraception needed only if inserted more than 7 days after menses starts (7 days of backup) 2

Safety Considerations for COCs

Before prescribing combined oral contraceptives, assess for contraindications:

  • COCs increase venous thromboembolism risk 3-4 fold (up to 4 per 10,000 woman-years) 2, 3
  • Avoid in severe or uncontrolled hypertension 3
  • Monitor blood pressure at follow-up visits 1, 2
  • Smoking is NOT a contraindication in women under age 35 2

Alternative Options

Progestin-Only Methods

If estrogen is contraindicated but LNG-IUS is declined:

  • Depot medroxyprogesterone acetate (DMPA) 150 mg intramuscularly every 12 weeks can reduce bleeding 2
  • For heavy bleeding with DMPA, add NSAIDs for 5-7 days 2
  • Amenorrhea is common after ≥1 year of continuous DMPA use 2
  • Caution: DMPA causes fluid retention and is contraindicated in heart failure 2

Contraceptive Vaginal Ring

  • NuvaRing releases 15 μg ethinyl estradiol and 120 μg etonogestrel daily 2
  • Provides comparable effectiveness to COCs with simpler once-monthly insertion 2

Treatment Algorithm

  1. Rule out underlying pathology: pregnancy, infection, structural lesions (fibroids, polyps), bleeding disorders 1
  2. First choice for most women: Monophasic COC with 30-35 μg ethinyl estradiol + levonorgestrel or norgestimate 1, 2
  3. If COCs contraindicated or maximum efficacy needed: LNG-IUS 3, 4
  4. If breakthrough bleeding on COCs: Add NSAIDs for 5-7 days 1
  5. If bleeding persists beyond 3-6 months: Re-evaluate for underlying gynecological problems 1
  6. If medical management fails: Counsel about endometrial ablation or hysterectomy 1

Follow-Up

  • No routine follow-up visit required for COCs, but patients should return for side effects or concerns 1, 2
  • Assess satisfaction with the method and any health status changes at follow-up 1
  • For LNG-IUS, reassess if bleeding persists beyond 6 months 3
