What is the management plan for a 19-year-old female experiencing increased bleeding after starting birth control?

Management of Increased Bleeding After Starting Birth Control in a 19-Year-Old

First, reassure the patient that bleeding irregularities during the first 3-6 months of hormonal contraceptive use are common and generally not harmful, then evaluate for underlying conditions before initiating treatment if bleeding persists beyond 3 months or is unacceptable to the patient. 1

Initial Evaluation

Before treating the bleeding, you must rule out specific underlying causes:

• Pregnancy testing is mandatory—pregnancy and contraceptive misuse are frequent causes of abnormal bleeding 2
• Assess medication compliance and proper pill-taking technique, as misuse of oral contraceptives is a common culprit 1, 2
• Screen for sexually transmitted infections that could cause bleeding 1
• Evaluate for drug interactions with other medications, particularly those affecting contraceptive metabolism 1
• Consider pathologic uterine conditions including polyps and fibroids if clinically indicated 1
• Check for cigarette smoking, which can contribute to bleeding irregularities 1

Treatment Algorithm Based on Timing and Contraceptive Type

If Using Combined Oral Contraceptives (COCs)

For bleeding within the first 3 months:

• Provide counseling and reassurance that this is expected and typically resolves 1, 2
• No medical intervention is needed during this adaptation period 2

For persistent bleeding beyond 3 months or unacceptable bleeding:

1. First-line treatment: NSAIDs for 5-7 days during bleeding episodes 3, 1

2. Alternative or additional first-line option: Hormonal treatment (if medically eligible) 3, 1

   • Low-dose COCs containing 30-35 μg ethinyl estradiol for 10-20 days 1, 4
   • Or additional estrogen supplementation for 10-20 days 3, 1

3. For extended/continuous regimen users with heavy bleeding:

   • Consider a hormone-free interval of 3-4 consecutive days 3, 1
   • Critical caveat: Do NOT use hormone-free intervals during the first 21 days of extended/continuous use 1
   • Do NOT use more than once per month as contraceptive effectiveness may be reduced 3, 1

4. If bleeding persists despite treatment:

   • Switch to a different COC formulation with higher estrogen content or different progestin 2
   • Counsel on alternative contraceptive methods and offer another method if desired 3, 1

If Using Progestin-Only Pills (POPs)

Approximately 40% of POP users experience vaginal bleeding/spotting, with 25% discontinuing for this reason 5, 6

Treatment options:

• Most effective: Add norethisterone acetate 5 mg to the existing POP regimen, which significantly reduces bleeding frequency and quantity after 2,4, and 6 weeks 5
• Alternative: NSAIDs for 5-7 days during bleeding episodes 2
• Supplemental estrogen during bleeding episodes (if medically eligible) 2

If Using Other Progestin-Only Methods (Implants, IUDs, DMPA)

• NSAIDs for 5-7 days during bleeding episodes 3
• For LNG-IUD or implant users: Can add hormonal treatment with COCs or estrogen for 10-20 days if medically eligible 3
• For DMPA users: NSAIDs for 5-7 days, or hormonal treatment with COCs/estrogen for 10-20 days 3

Special Considerations for Adolescents

This 19-year-old patient falls into a population that may benefit from more frequent follow-up visits 3. However, no routine follow-up visit is required unless the patient has concerns 3, 1.

Important Caveats

• Estrogen-containing methods increase VTE risk from 2 per 10,000 woman-years to 7-10 per 10,000 woman-years 4, 7
• Enhanced counseling about expected bleeding patterns reduces method discontinuation 4
• Bleeding irregularities are the most common reason for contraceptive discontinuation, leading to unplanned pregnancy 2, 8
• If the patient finds bleeding unacceptable despite treatment, switching methods is preferable to discontinuation without alternative contraception 3, 1

Follow-Up Recommendations

Advise the patient to return at any time for concerns, but routine follow-up is not required 3, 1. At any follow-up visit:

• Assess satisfaction with current method 3
• Evaluate changes in health status affecting contraceptive eligibility 3
• Measure blood pressure if using CHCs 3
• Consider assessing weight changes if the patient is concerned 3
