2What to ask
  • Time since first and any other unprotected sex this cycle
  • LMP, cycle length (where in the cycle)
  • Contraception normally used / missed pills
  • Weight/BMI
  • Medicines: enzyme inducers (e.g. carbamazepine, rifampicin, St John’s wort); progestogen use in last 7 days
  • Breastfeeding; severe asthma on oral steroids (UPA)
  • STI risk; consent and safeguarding
3What to examine
  • Usually none needed
  • Pregnancy test if indicated
4How to do it — the senior at your shoulder

Work out the timing

Ask about every episode of unprotected sex since the last period. EC timing runs from the first episode in this cycle, but treatment can still be given for recent episodes.

Choosing the pill

Ulipristal works later in the cycle (closer to ovulation) and up to 120 h. Levonorgestrel works up to 72 h and is the option if hormonal contraception was used in the last 7 days or with enzyme inducers (at 3 mg).

5Decide — investigate only if it changes the plan

Choosing EC (FSRH)

  • Within 120 h and eligible → copper IUD is most effective (offer to all)
  • Within 120 h → ulipristal 30 mg (unless progestogen in last 7 days, enzyme inducers, severe asthma on oral steroids)
  • Within 72 h → levonorgestrel 1.5 mg (3 mg if BMI > 26, weight > 70 kg, or enzyme inducers)

Safeguarding check for every under-16; offer STI testing.

InvestigationOnly if…
Pregnancy testIf UPSI > 21 days ago or period late; repeat 3 weeks after EC
6Treat & send home

Management & advice

  • Copper IUD is the most effective EC — offer to all eligible (within 120 h of first UPSI, or within 5 days of earliest likely ovulation)
  • If IUD not wanted/available: oral EC now, and refer for IUD if still possible
  • Vomiting within 3 h of a pill → repeat dose
  • After levonorgestrel: start hormonal contraception immediately (condoms 7 days, 2 days for POP)
  • After ulipristal: wait 5 days before starting hormonal contraception (condoms meanwhile)
  • STI testing advice; pregnancy test in 3 weeks

Refer / follow-up

  • Copper IUD → sexual health / contraception service (same or next day)
  • Under 16 / safeguarding → per local policy
  • Sexual assault → SARC

DrugDoseDuration / notes
Ulipristal acetate (within 120 h) BNF ↗30 mg single doseMore effective than levonorgestrel; avoid if progestogen taken in the last 7 days, enzyme inducers, severe asthma on oral steroids; breastfeeding — express and discard for 1 week
Levonorgestrel (within 72 h) BNF ↗1.5 mg single doseUse 3 mg if BMI > 26 or weight > 70 kg, or on enzyme inducers (FSRH)
7Safety-net
Say it like this

The copper coil is the most effective emergency contraception and also gives you ongoing contraception, so I can refer you today. If you’d prefer a tablet, take it now. If you’re sick within 3 hours, you’ll need another dose. Do a pregnancy test in 3 weeks, or sooner if your period is late or unusual, and come back if you get tummy pain.

Come back / call 111 — or 999 if severe — if:

  • Next period more than 7 days late, unusually light or short — do a pregnancy test
  • Lower abdominal pain (ectopic)
  • Do a pregnancy test 3 weeks after the unprotected sex anyway

9Where juniors slip up
  • Not offering the copper IUD
  • Standard-dose levonorgestrel for BMI > 26 / weight > 70 kg
  • Starting hormonal contraception straight after ulipristal
  • Missing safeguarding in under-16s
▶Practise the decision

Revision practice. Work through a real or imagined case to rehearse the reasoning. It builds a model note to learn from. It doesn’t replace your judgement, your seniors or local guidance.
