Patient Script
For the friend playing the patient role
Character Overview: You are Mhairi Galbraith, a 28 year old lettings negotiator at a busy estate agency. You work long, target driven weeks and you rent a flat with your friend Pippa. You have been seeing Rafi, who works as a science technician at a secondary school, for about three months. You are usually careful and use condoms, but four nights ago, at about eleven o'clock at night, after a few drinks at his flat, you did not use one. You have counted it up and it is now about 90 hours, and it is roughly five in the afternoon. You only really took it in when Pippa asked how things were going and you panicked. You are cheerful and quick talking, a little embarrassed about the delay, and you want this sorted without fuss. You assume the morning after pill is the answer, and you would like a prescription sent to your chemist so you can collect it on the way home. You are not hiding anything, but you do not think of your herbal capsules as medicine, so you only mention them when asked about anything you buy or take yourself.
Opening Sentence: "Hi, doctor. I need the morning after pill, please. I had sex without a condom a few nights ago and I'd like to get it from my chemist, if you could send a prescription over."
History if Asked (Data Gathering Phase)
- ●When it happened: "Four nights ago, around eleven at night. It's about five now, so I make it ninety hours, give or take. I worked it out on my phone."
- ●What happened: "We'd had a few drinks at his flat and we just didn't use a condom. We always have before. It was vaginal sex, once. He didn't finish inside me, but I know that doesn't count for much."
- ●Why she is ringing now: "I was flat out at work and put it to the back of my mind. Then Pippa asked if I was sure I wasn't worried, and I went cold. I looked it up and one website said three days and another said five, so I thought I'd better ring."
- ●Other sex since or before: "No. Only that once, and no other unprotected sex this cycle."
- ●Periods: "Regular, every 28 days or so, five days long, moderate. My last one started 17 days ago. Nothing odd about it."
- ●Contraception: "None at the moment. I was on the combined pill but stopped it about fourteen months ago because it made me feel flat. We've just been using condoms."
- ●Pregnancy so far: "I haven't done a test. It's far too soon, isn't it?"
- ●Symptoms now: "No pain, no bleeding between periods, no discharge, no smell, nothing when I pass water. I feel fine physically."
- ●Taking tablets or anything bought: "Oh, the St John's wort. I buy it from the health food shop, two capsules every morning. I started about eight weeks ago because I've been feeling flat and tired. Pippa swears by it. It's only herbal, I didn't think it counted."
Ideas, Concerns, Expectations
Gating note: Mhairi does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks the best option is, what is worrying her, or what she was hoping for today.
- ●Ideas: She thinks the morning after pill is the only real option and that the chemist sells it to everyone, so it must be simple. She has heard the coil is for older women who have had children and that it is agony to have put in. "Isn't it just a tablet? I thought the coil was for people who've had kids. My friend's cousin said it was the worst pain of her life."
- ●Concerns: She is most worried about getting pregnant, because her promotion is being decided in about six weeks and the relationship is still new. She is also embarrassed that she left it so long. She fears the coil hurting, and about taking time off work for it. "I just can't be pregnant right now. And I feel stupid for waiting."
- ●Expectations: She expects a prescription for the tablet to be sent to her chemist so she can pick it up on the way home and not pay for it. "I rang so you could send it to the chemist. I'd rather not pay forty quid if the doctor can do it."
If Asked: Medical History and Medications
Gating note: Mhairi answers each of these plainly when the doctor asks about it.
- ●Other health problems: "Nothing. No asthma, no migraines, no blood clots, no operations. My periods are fine."
- ●Prescribed medicines: "None."
- ●Herbal or bought medicines: "Only the St John's wort. Nothing else, no vitamins, no antibiotics, nothing from a clinic."
- ●Allergies: "None."
- ●Mood: "A bit flat for a couple of months, mostly work pressure. I'm tired and I snap at people, but I sleep okay, I still enjoy my weekends and I have never had thoughts of harming myself. I haven't told anyone at the surgery."
- ●Pelvic problems: "I've never had a pelvic infection, an ectopic or any pelvic surgery. I've never been pregnant. I've never had a coil."
- ●Weight: "About fourteen stone. I'm five foot five, so I know I'm on the big side."
- ●Cervical screening and STI tests: "My smear was normal two years ago. I've never had a full sexual health check, just a chlamydia test years ago at uni, negative."
Social History and Lifestyle Impact
- ●Work: Lettings negotiator. Her days are mostly viewings and phone calls, and she is rarely at her desk. She has a promotion decision in about six weeks. If asked about appointments, she says she is free tomorrow before ten in the morning or at lunchtime, and she could leave this evening if there is something urgent.
- ●Home: Rents a flat with Pippa. Pippa knows about the sex and the worry but nobody else does. Her parents live far away and she has not told them anything.
- ●Partner: Rafi is kind and says he had a sexual health check at the start of the year and was clear. She has not had one herself. She does not know whether he has had other partners.
- ●Alcohol, smoking and drugs: A couple of glasses of wine at weekends. Non smoker. No drugs.
- ●Travel: Drives to work and can drive anywhere in the city. A sexual health clinic or a coil appointment in a different building is not a problem for her.
If Asked: Associated Symptoms
Gating note: Mhairi answers these only when asked. Every one is negative unless stated.
- ●If asked about abdominal or pelvic pain, vaginal discharge, bleeding after sex or between periods, or pain during sex: "No, none of that."
- ●If asked about fever or feeling unwell: "No."
- ●If asked about low mood in more detail, hopelessness or thoughts of self harm: "I feel flat, not hopeless. I'd never hurt myself."
- ●If asked about whether the sex was consensual or whether anyone pressured her: "Totally consensual. Rafi's lovely. It was just the drink and the moment."
- ●If asked about breastfeeding, recent pregnancy or recent miscarriage: "No."
Responses to Management (The Negotiation Phase)
- ●If the doctor explains that the chemist pill may not work well for her, or that it is past the usual window for it:
- ●Reaction: Surprised. "But the chemist gives it out all the time. Isn't ninety hours still inside five days?" If told her weight and the St John's wort both matter: "It's herbal. How can a plant do anything to the pill?" She accepts it once it is explained that the capsules speed up the way the liver clears some hormones, and she asks what her options are.
- ●If the doctor recommends the copper coil as the most effective option:
- ●Reaction: Uneasy. "A coil? Honestly I thought that was for older women. Does it hurt?" She wants plain answers about the pain, how long it takes and whether she can go back to work afterwards. She asks, "How long does it stay in? I don't want a baby for a good few years, but I might want one someday." She is reassured to hear it can be taken out at any time and that fertility returns afterwards.
- ●If the doctor says the coil must be fitted within a time limit, and arranges it:
- ●Reaction: Anxious about the clock. "So how long have I got? What if I can't get an appointment in time?" She is relieved when given a clear plan: "I can do tomorrow morning before ten, or I could get to a clinic this evening." If told a back up tablet can be taken meanwhile or if the coil is not possible, she asks which one and whether it will actually work.
- ●If the doctor offers or discusses a tablet instead, because she declines the coil:
- ●Reaction: Practical. "Which one, and will it definitely work? How likely am I to get pregnant if it fails?" If told no tablet is certain and that it is less reliable for her: "Right, so the coil really is the best bet. I think I'd rather try for that." She asks to be told what to do if she is sick after a tablet.
- ●If the doctor asks about long term contraception or the St John's wort:
- ●Reaction: Open once it is raised. "If I have the coil, do I need the pill as well? And should I stop the St John's wort? It's the only thing helping with how I feel." If the doctor suggests reviewing her mood, she agrees: "I'd actually like that. I just didn't want to make a fuss."
- ●If the doctor discusses STI testing, a pregnancy test and safety netting:
- ●Reaction: Willing but wants details. "Do I need the tests? Rafi says he's clear." If told the reasons: "Fine. Can that be done when I'm there for the coil?" About the pregnancy test: "How long do I wait, and what would make you worry?" If the safety netting is vague, such as "come back if there's a problem": "What kind of problem? What would I look out for?" She repeats back specific advice clearly.

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Mhairi asks for "the morning after pill" from a pharmacy. Three facts make the standard tablet a poor choice: she is about 90 hours from unprotected sex, her BMI is 33, and she takes St John's wort, a liver enzyme inducer. Each lowers the effect of oral emergency contraception, and together they point to the copper intrauterine device (IUD).
- ●The model plan: recognise that about 30 hours remain before the 120 hour limit, recommend an emergency copper IUD as the most effective method, and book a fitting today or tomorrow. Explain why a tablet is second line for her, and offer one as a fallback if she declines or cannot be fitted in time.
- ●Acceptable alternatives: agreeing an oral method with her after an honest account of its limits, with follow up, still passes the decision. Offering a tablet as cover while a coil is booked also passes.
- ●The consultation also needs ongoing contraception, sexually transmitted infection (STI) screening, and attention to her low mood, which is the reason she takes the herbal remedy.
Timing: What Each Method Can Still Do
- ●Copper IUD: effective when fitted up to 5 days (120 hours) after unprotected sex. The Faculty guidance (Clinical Effectiveness Unit, now the College of Sexual and Reproductive Health, CoSRH) also allows fitting up to 5 days after the earliest expected ovulation, whichever is later. Her last period began 17 days ago on a 28 day cycle, so the earliest likely ovulation is about the day of the sex and the later limit falls on the same day as the 120 hour limit. The simple 120 hour rule is enough, and the call is urgent because it falls about 30 hours away.
- ●Levonorgestrel: licensed within 72 hours. The British National Formulary (BNF) says it may be used between 72 and 96 hours after sex, but efficacy decreases with time. At 90 hours it is off licence and less effective.
- ●Ulipristal acetate: 30 mg single dose, licensed up to 120 hours, so the timing alone would not exclude it.
Why Weight and St John's Wort Change the Choice
- ●Body weight: the BNF advises that a higher dose of levonorgestrel should be considered for a weight above 70 kg or a BMI above 26. At 91 kg and BMI 33 she is above both. CKS (revised October 2025, based on CoSRH 2023) says that when a copper IUD is not used and the BMI is above 26 or the weight above 70 kg, offer ulipristal or a double dose (3 mg) of levonorgestrel, not the standard 1.5 mg.
- ●St John's wort: the BNF interactions list says it is predicted to decrease the efficacy of ulipristal and refers to CoSRH guidance. For levonorgestrel, the BNF says the effectiveness of an emergency dose could be reduced in women taking enzyme inducing drugs, and for up to 4 weeks after stopping, and that a copper IUD should preferably be used instead. If the IUD is undesirable or inappropriate, the BNF says the levonorgestrel dose should be increased to a single 3 mg dose, with pregnancy excluded afterwards.
- ●The two reducing factors affect both tablets. That is why the IUD is recommended: it works by a copper effect in the womb and is not affected by weight or enzyme inducers.
- ●If she declines the coil, the tablet choice is a judgement made with her. CKS and CoSRH advise that with an enzyme inducer (including for 28 days after stopping) the copper IUD is preferred, and if it is declined the oral option is levonorgestrel 3 mg as a single dose within 72 hours, off licence with unknown effectiveness. Ulipristal is stated as not recommended in the main pathway, although one CKS interactions section still lists it as possible with a warning that effectiveness is unknown. At 90 hours she is beyond the 72 hours given for the double dose, so no tablet is well supported for her. A candidate who offers either tablet as cover while the coil is arranged, with that honestly explained, still passes. She should be told in plain terms that no tablet is certain.
- ●Herbal does not mean harmless: ask by name about anything bought, herbal or supplements.
Arranging the Coil
- ●Many practices cannot fit a coil on the day. Use the practice fitter or a sexual health clinic with same day or next day emergency coil appointments. Book it while she is on the phone, confirm she can attend, and say what to do if it falls through.
- ●The fitter will check for pregnancy risk from other recent sex, signs of infection and uterine problems. Ask about pelvic pain, discharge, bleeding after sex, past pelvic infection, ectopic pregnancy and previous coil use before you send her.
- ●Nulliparous women (those who have not given birth) can use a copper IUD. The belief that it is only for older women who have had children is a myth to correct. Fitting is uncomfortable for some people, so offer analgesia and explain that it takes minutes.
Ongoing Contraception
- ●A copper IUD fitted for emergency contraception can stay as her regular method. Depending on the device, it lasts 5 to 10 years, and it can be removed at any time with fertility returning promptly. This answers her fear that it is permanent.
- ●If she prefers hormonal contraception, her St John's wort matters. Enzyme inducers reduce the reliability of the combined pill, the progestogen only pill and the implant under the UK Medical Eligibility Criteria (UKMEC), while the copper IUD, the levonorgestrel intrauterine system and depot medroxyprogesterone acetate are not affected. If she takes an oral emergency tablet, CKS and CoSRH advise waiting 5 days (at least 120 hours) after ulipristal before starting or continuing a hormonal method, using condoms or abstaining meanwhile and until the method is effective, with a pregnancy test 21 days later. After levonorgestrel a hormonal method can be quick started immediately. After a copper IUD none of this is needed.
- ●The inducing effect persists for up to 4 weeks after stopping the herbal remedy, so a hormonal method chosen soon after should allow for it.
Follow Up, STI Screening and Safety Netting
- ●Advise a pregnancy test about 3 weeks after the unprotected sex, or earlier if a period is more than a week late, lighter than usual or unusually timed. No emergency method is 100 percent effective, including a coil.
- ●Warn about ectopic pregnancy: lower abdominal pain, abnormal bleeding or faintness in the following weeks needs same day assessment. After a coil, severe pain, fever or abnormal discharge also need same day contact, because of infection or a displaced device.
- ●If she takes an oral tablet and vomits within 3 hours, she should contact the practice or pharmacy for another dose; this applies to both ulipristal and levonorgestrel (CKS).
- ●Offer chlamydia and gonorrhoea testing, and HIV and syphilis blood tests, as she has a three month partner and has never had full screening. Follow British Association for Sexual Health and HIV (BASHH) advice on test windows and repeat tests where exposure was recent. Her partner's reported clear result is not a substitute.
Mood and the Herbal Remedy
- ●She started St John's wort for feeling flat and tired and has told nobody. A short, kind assessment is part of the consultation: duration, sleep, interest, hopelessness and self harm.
- ●NICE guideline NG222 on depression advises that clinicians advise people of the different potencies of the preparations and the potential serious interactions of St John's wort, including with hormonal contraceptives, and do not prescribe or advise its use by people with depression because of uncertain doses and variation between preparations.
- ●Do not tell her to stop abruptly and leave. Offer a proper mood review, discuss evidence based options, and arrange follow up. She stopped the combined pill because it made her feel flat, which is relevant to the method she is likely to choose.
Communication Points Specific to This Case
- ●Mhairi is embarrassed about the delay. A calm line such as "we still have time to do this well" keeps her talking.
- ●Explain the three reasons (time, weight, herbal capsules) in everyday words and ask her to say them back.
- ●Respect a decision to take a tablet. Present the coil as the best option, give her the numbers in plain words, and avoid pushing once she has decided.
Common Mistakes in This Station
- ●Sending a standard dose levonorgestrel prescription to the pharmacy without counting the hours, noting her weight or asking about herbal products.
- ●Telling her she is "too late" because she is past 72 hours, forgetting the coil and ulipristal.
- ●Offering ulipristal without noticing the St John's wort, or treating herbal products as harmless.
- ●Mentioning the coil but not booking it, leaving her to find an appointment before the limit.
- ●Forgetting ongoing contraception, STI screening, the pregnancy test, or the mood problem that explains the herbal remedy.
- ●Safety netting with "come back if you are worried" and no named symptoms.
