Recommended Oral Contraceptive Pills for Pediatric Patients
For adolescent patients requiring contraception, low-dose combined oral contraceptives (COCs) containing ≤35 μg ethinyl estradiol are recommended as the first-line oral contraceptive option due to their excellent contraceptive efficacy and favorable safety profile. 1
First-Line Oral Contraceptive Options
Combined Oral Contraceptives (COCs)
- Preferred formulation: Pills containing levonorgestrel or norethisterone combined with ≤35 μg ethinyl estradiol 1, 2
- Lowest effective dose: COCs with 20 μg ethinyl estradiol/100 μg levonorgestrel provide excellent contraception with a Pearl index of 0.88 3
- Efficacy: 91% effective with typical use (9% failure rate) 4
- Advantages:
- Excellent contraceptive efficacy when taken correctly
- Predictable bleeding patterns after initial cycles
- Non-contraceptive benefits (acne improvement, menstrual regulation)
Progestin-Only Pills (Mini-Pills)
- Consider for: Patients with contraindications to estrogen use 4
- Efficacy: Lower than COCs due to stricter adherence requirements 4
- Key consideration: Requires very stringent adherence to timing of doses 4
Clinical Decision Algorithm
Assess for contraindications to estrogen:
- Severe uncontrolled hypertension (≥160/100 mmHg)
- Ongoing hepatic dysfunction
- Complicated valvular heart disease
- Migraines with aura or focal neurologic symptoms
- History of thromboembolism or thrombophilia
- Complications of diabetes 1
If no contraindications to estrogen:
If contraindications to estrogen exist:
Important Prescribing Considerations
Initiation and Management
- No pelvic examination is required before starting COCs 1
- Prescribe up to 1 year of COCs at initial visit 1
- Schedule follow-up 1-3 months after initiation to address side effects 1
- Advise using backup contraception (condoms) for first 7 days after starting 1
Drug Interactions
- Reduced efficacy with:
- Most broad-spectrum antibiotics do not affect COC effectiveness 1
- Monitor lamotrigine levels as COCs may decrease plasma concentrations 5
Special Populations
- Patients with sickle cell disease: Progestin-only methods preferred (implants, injections, progestin-only pills) due to increased thrombosis risk 4
- Patients with obesity: All contraceptive methods appropriate except DMPA which may cause additional weight gain 1
Safety Considerations
Stroke Risk by Estrogen Dose
- ≤20 μg ethinyl estradiol: Lowest risk
- 20-35 μg ethinyl estradiol: Moderate risk
35 μg ethinyl estradiol: Highest risk 1
Common Side Effects to Discuss
- Irregular bleeding (especially in first 3 months)
- Headache
- Nausea
- These typically resolve within 3 months 1
Pediatric-Specific Considerations
- Safety and efficacy are expected to be the same for postpubertal adolescents under 16 years and users 16 years and older 5
- Not indicated for use before menarche 5
- Emphasize importance of taking pills at the same time each day 1
- Counsel on need for STI protection with condoms in addition to contraception 1
Monitoring
- Follow up 1-3 months after initiation
- Monitor blood pressure annually
- Assess for any new-onset contraindications at follow-up visits
- No routine laboratory monitoring is required for healthy adolescents
By following these recommendations, clinicians can provide safe and effective oral contraception for adolescent patients while minimizing risks and maximizing benefits.
