- ๐ 7 days: COC (Combined pill), injection, implant, LNG-IUS (hormonal coil)
๐ Intrauterine Device (IUD โ Copper Coil)

๐ฉโ๐ง Contraception in Adolescents and Young Women
Young people (<18) often present with unique challenges: safeguarding, confidentiality, irregular cycles, and higher risk of unintended pregnancy and STIs.
Doctors must balance autonomy with child protection responsibilities.
โ๏ธ Legal & Ethical Framework (UK โ Fraser Guidelines)
- Under-16s may consent to contraception if they demonstrate competence (Gillick competence).
- Confidentiality must be respected unless there are safeguarding concerns (e.g. coercion, abuse).
- Discuss safe sex, STI protection, and encourage parental involvement if appropriate.
๐ Key Considerations
- High rates of inconsistent use and discontinuation โ need methods that are easy to remember or โfit and forgetโ.
- STI risk is high โ always advise on condom use even if another method chosen.
- Safeguarding concerns (sexual exploitation, coercion, abuse) must always be considered.
๐ก Recommended Methods
- Long-Acting Reversible Contraception (LARC):
โ Implants (etonogestrel) ๐ and IUS/IUD ๐ are highly effective, donโt rely on daily adherence, and are recommended by NICE/FSRH as first-line for young people.
โ Need careful explanation and reassurance about insertion.
- Combined Oral Contraceptive (COC):
โ Popular choice for cycle regulation and acne ๐ธ.
โ Requires good adherence; missed pills are common in teenagers.
- Progestogen-Only Pill (POP):
โ Good option if oestrogen contraindicated; but needs strict daily compliance โฑ๏ธ.
- Condoms:
โ Essential for STI protection ๐ก๏ธ, always advised alongside other contraception.
๐ซ Methods to be cautious with
- Depot injection (Depo-Provera): Can reduce bone mineral density ๐ฆด, a concern in adolescents; should not be first-line unless no alternatives are suitable.
๐ธ Wider Support & Health Promotion
- STI screening (Chlamydia, Gonorrhoea) should be offered routinely.
- HPV vaccination ๐ is crucial in prevention of cervical cancer.
- Discuss healthy relationships, consent, and sexual wellbeing as part of holistic care.
- Encourage follow-up and ongoing support, as adherence can be challenging.
๐งช Emergency Contraception
- โก Copper IUD: Most effective, can be fitted up to 5 days after unprotected sex.
- ๐ Levonorgestrel pill: Within 72h; effectiveness decreases with time.
- ๐ Ulipristal acetate (ellaOne): Up to 120h after sex, more effective than levonorgestrel after 72h; avoid if on hormonal contraception (requires 5-day gap).
โจ Key Exam Tips
- ๐ก๏ธ IUD = immediate protection + emergency contraception.
- โฑ๏ธ POP = 2 days; everything else (except copper coil) = 7 days if not started day 1 of period.
- ๐ COC โ avoid in smokers >35 & migraine with aura.
- ๐ธ POP safe in smokers & breastfeeding women.
- ๐ก๏ธ Condoms = only STI protection.

- ๐ Case 1 โ Age 19 (Combined Pill): University student requested contraception for the first time. Regular cycles, BMI 22, non-smoker, no migraines or family history of thrombosis.
Choice: Combined oral contraceptive pill (ethinylestradiol + levonorgestrel).
Advice: Take at the same time daily; 21 days on, 7 days off. Discussed benefits (cycle control, acne improvement) and risks (VTE, hypertension).
Teaching point: The combined pill is first-line for young, healthy, non-smoking women - ensure BP and BMI are checked before prescribing.
- ๐ญ Case 2 โ Age 36 (Progestogen-Only Pill): Smoker (10/day) seeking contraception. Combined pill contraindicated due to age and smoking.
Choice: Desogestrel-containing progestogen-only pill (POP).
Advice: Take at the same time daily (within 12-hour window); may cause irregular bleeding.
Teaching point: POP is safe in smokers and those with cardiovascular risk factors - acts mainly by cervical mucus thickening and endometrial suppression.
- ๐ฉบ Case 3 โ Age 28 (LARC): Woman with chaotic lifestyle and difficulty remembering tablets requested a low-maintenance option.
Choice: Levonorgestrel intrauterine system (Mirena).
Advice: Provides 5 yearsโ protection, lightens or stops periods, and is rapidly reversible. Counselling given on insertion discomfort and infection risk.
Teaching point: Long-acting reversible contraception (LARC) is highly effective and suitable for those seeking โfit and forgetโ options.
- ๐คฑ Case 4 โ Age 32 (Postpartum): Six weeks after delivery, breastfeeding and undecided about more children.
Choice: Progestogen-only implant (etonogestrel, Nexplanon).
Advice: Safe while breastfeeding; effective for 3 years; may cause irregular bleeding. Discussed timing of insertion and fertility return after removal.
Teaching point: Oestrogen-containing methods are avoided in the first 6 weeks postpartum due to VTE risk - progestogen-only options are preferred for lactating women.
