Recommended Contraceptive Methods for Individuals
Long-acting reversible contraceptives (LARCs), specifically IUDs and implants, are the recommended first-line contraceptive methods for most individuals due to their superior effectiveness (<1% failure rate) and minimal user intervention requirements. 1, 2
Effectiveness Hierarchy of Contraceptive Methods
Tier 1: Most Effective (Failure rate <1%)
- Intrauterine Devices (IUDs)
- Copper T 380A (Cu-IUD): 0.8% typical failure rate
- Levonorgestrel IUD (LNG-IUD): 0.1-0.2% typical failure rate
- Contraceptive Implant: 0.05% typical failure rate
- Sterilization
- Female sterilization: 0.5% typical failure rate
- Male sterilization: 0.15% typical failure rate
Tier 2: Highly Effective (Failure rate 3-9%)
- Injectable contraception (DMPA): 0.3-6% typical failure rate
- Combined hormonal contraceptives (pills, patch, ring): 5-9% typical failure rate
- Progestin-only pills: 5-9% typical failure rate
Tier 3: Moderately Effective (Failure rate >10%)
- Male condoms: 14% typical failure rate
- Female condoms: 21% typical failure rate
- Withdrawal method: 19% typical failure rate
- Fertility awareness methods: 25% typical failure rate
- Diaphragms with spermicide: 20% typical failure rate
Selection Algorithm
Assess medical eligibility:
Consider effectiveness needs:
- For individuals with high priority on preventing pregnancy, recommend LARCs or sterilization
- For those who can accept some pregnancy risk, Tier 2 or 3 methods may be acceptable
Evaluate user preferences:
- Need for menstrual cycle control
- Desire for non-contraceptive benefits (acne treatment, reduced menstrual bleeding)
- Comfort with insertion procedures
- Frequency of administration (daily, weekly, monthly, years)
- Preference for hormonal vs. non-hormonal methods
Consider STI protection needs:
- Recommend condom use in addition to other methods for individuals at risk of STIs 1
- Remember that hormonal methods and IUDs do not protect against STIs/HIV
Starting Contraceptive Methods
When to Start
- Most contraceptive methods can be started anytime during the menstrual cycle if pregnancy can be reasonably ruled out 1
- For LNG-IUD, implant, DMPA, and CHCs started >5-7 days after menses began, use backup contraception for 7 days 1
- For norethindrone/norgestrel POP, use backup for 2 days if started >5 days after menses 1
- For drospirenone POP, use backup for 7 days if started >1 day after menses 1
Required Examinations Before Initiation
- Cu-IUD/LNG-IUD: Bimanual examination and cervical inspection 1
- Combined hormonal contraceptives: Blood pressure measurement 1
- Implant, DMPA, POPs: No specific examinations required 1
Managing Common Issues
Bleeding Irregularities
- For Cu-IUD users with heavy/prolonged bleeding: NSAIDs for 5-7 days 1, 2
- For LNG-IUD, implant users with spotting/bleeding: NSAIDs for 5-7 days 1, 2
- For implant users with heavy bleeding: Consider NSAIDs, hormonal treatment with low-dose COCs, or tranexamic acid 1, 2
Expected Bleeding Patterns
- LNG-IUD: Initial spotting common, reduces menstrual blood loss by 88-95% after 6-12 months; about half of users experience amenorrhea by 2 years 2
- Implant: Unpredictable bleeding patterns common
- DMPA: Amenorrhea often develops with continued use
- Combined hormonal methods: Regular, predictable bleeding patterns
Special Considerations
Adolescents
- LARCs are appropriate for adolescents and nulliparous women 1
- Consider confidentiality needs and ease of use
Perimenopausal Women
- LNG-IUD particularly beneficial as it can manage heavy bleeding while providing endometrial protection 2
- Consider bone mineral density effects with long-term DMPA use 3
Medication Interactions
- Certain anticonvulsants, rifampin, and rifabutin may reduce effectiveness of hormonal methods 1
- HIV medications may interact with hormonal contraceptives 1
Common Pitfalls to Avoid
Overestimating user adherence: Perfect use rates differ significantly from typical use rates for user-dependent methods 4
Underutilizing LARCs: Despite being the most effective reversible methods, LARCs are still underutilized compared to oral contraceptives 4
Imposing unnecessary medical barriers: Few examinations or tests are needed before starting most contraceptive methods 1
Assuming bleeding with LNG-IUD is normal: Heavy bleeding with LNG-IUD is uncommon and warrants evaluation 2
Neglecting STI protection: Always counsel on condom use for STI prevention regardless of contraceptive choice 1
