Patient Script
For the friend playing the patient role
Character Overview: You are Nadia Chowdhury, a 26 year old recruitment consultant who spends most days on video calls with clients and applicants. You live with your boyfriend Sam, and your parents and sister live nearby. You are taking this call at lunchtime from a small meeting room at work, wearing a full face of makeup.
You had spots as a teenager and went on the combined pill at 17 for painful periods. Your skin cleared and stayed clear for years. You stopped the pill about six months ago, and within six weeks deep, painful spots began along your jaw and chin. The gel has not helped. Your friend Hollie at work took tablets from the hospital skin clinic last year and says they cured her skin, so you want the same. You do not know what they are called.
You do not volunteer why you stopped the pill. The real reason is that your cousin Ruksana had a blood clot in her lung last year while on the pill, and it frightened you. You explain this only if asked why you stopped.
You are friendly and chatty, but embarrassed and a little flat. Your voice drops when you talk about your face and speeds up, anxious, when clots come up.
Opening Sentence: "Hi, thanks for calling. So my skin's been really bad since I came off the pill, and the gel I was given just isn't doing anything. My friend at work had some tablets from the hospital that she says cured her spots completely. Is that something I could have?"
History if Asked (Data Gathering Phase)
- ●Where the spots are and what they are like: "Mostly along my jaw on both sides and round my chin, a few down my neck, the odd blackhead on my forehead. Nothing on my chest or back. There are two sorts. Loads of little red ones, some with yellow heads, fifteen or twenty at a time. And big, deep lumps under the skin that really hurt. They never come to a head, they just sit there for two or three weeks. Usually four or five at a time. As soon as one goes down, another comes up."
- ●Marks, picking and periods: "Brown marks that take months to fade, and in the last couple of months two or three little dents on my chin. I pick at the little ones once they've got a head, I know I shouldn't. They're definitely worse the week before my period."
- ●How it started and which pill: "I went on the pill at 17 for painful periods and within a few months my skin cleared. It stayed clear the whole time. I came off it about six months ago, and within about six weeks the spots started, right when my periods came back. It was the one with levonorgestrel in it, the same throughout, no problems."
- ●How she has used the gel: "About fourteen weeks. At first it stung and went red and flaky, so for a couple of weeks I only used it every few nights. Since then it's every night, but I just dab it on the spots. Is that wrong? It's bleached two of my pillowcases. Honestly, no difference, and I've never had tablets for my skin."
- ●Makeup and skin care: "Full coverage foundation and concealer every day, I can't leave the house without it. I take it off with coconut oil because it's meant to be gentle, and sometimes I fall asleep with it still on."
Ideas, Concerns, Expectations
Gating note: Nadia does not raise any of the following herself. Each part comes out only when the doctor asks what she thinks is going on, what is worrying her, or what she was hoping for today.
- ●Ideas: She thinks coming off the pill sent her hormones haywire and that the pill was only hiding what her skin is really like. "I need something stronger, like Hollie had."
- ●Concerns: Her main fear is scarring. "My dad had terrible spots when he was young and his cheeks are really pitted. Now I'm getting dents on my chin, and I'm scared I'll end up with skin like his." If the doctor explores further: "I've started turning my camera off on client calls."
- ●Expectations: Something stronger than a cream, ideally Hollie's tablets, and not to go back on the pill. "Or at least something that actually works, not another cream."
If Asked: Medical History and Medications
Gating note: Nadia answers each of these plainly when the doctor asks. She explains why she stopped the pill only if asked why, and gives the details about Ruksana only if asked more about it.
- ●Past health: "Painful periods when I was younger. Anxiety at uni, six sessions of counselling helped, fine since, never any tablets."
- ●Why she stopped the pill: "Honestly? My cousin Ruksana had a blood clot in her lung last year. She was on the pill. She's 28, totally healthy, and she was in hospital for a week. It really scared me, so I just didn't start my next pack."
- ●More about Ruksana, and family clots: "It happened a few days after a really long flight back from visiting family in Australia. Tests said she hadn't inherited anything. Mum, Dad and my sister have never had a clot. I don't get migraines."
- ●Periods and hormones: "Regular since they came back, every 28 to 31 days. My last one started ten days ago and was normal. No extra hair, no thinning on my head, weight about the same."
- ●Medicines and contraception: "Just the gel, and vitamin D in winter. No steroids, protein shakes or supplements. No allergies. We use condoms every time. We want to save up for a flat first, so no baby for a few years, and I can't be pregnant."
- ●What she knows about Hollie's tablets: "From the hospital skin clinic. Her lips went dry and cracked, she kept getting nosebleeds, and she had to do a pregnancy test every month. But her skin's perfect now."
Social History and Lifestyle Impact
- ●Work and impact: In the office three days a week, home two. "Last month I skipped my best friend's birthday drinks because of the lumps on my chin. Some mornings I cry in front of the mirror before work."
- ●Mood: "It's getting me down. I feel ugly. But I'm sleeping and eating okay and I still enjoy things when I'm not thinking about my face. I wouldn't say I'm depressed." Asked directly about harming herself: "No. Never anything like that."
- ●Relationship and habits: "Sam says he doesn't even notice. But I notice." A couple of glasses of wine at weekends. Never smoked.
If Asked: Associated Symptoms
- ●Negatives, grouped: no fever and she feels well in herself; no joint pains; no spots that have burst into raw sores or bleeding crusts, "they're just lumps"; no headaches or eyesight problems; no new medicines before the spots started.
Responses to Management (The Negotiation Phase)
- ●If the doctor explains that Hollie's tablets can only be started by a skin specialist, or what they involve:
- ●Reaction: Disappointed. "So you can't give them to me?" Told that antibiotic tablets come first and count towards a referral: "That makes it feel less like I'm being fobbed off." Told about pregnancy prevention: "So that's why Hollie had all those pregnancy tests. Are condoms on their own not enough?" If pill plus condoms would count: "So if I went back on the pill and kept using condoms, that would cover it?" Told about mood effects: "With my anxiety at uni, would they even let me have it?"
- ●If the doctor suggests antibiotic tablets, or explains how to use the gel:
- ●Reaction: Wary. "Antibiotics for three months? Isn't that bad for you, with resistance? Will it mess my stomach up?" On the gel: "So the whole area, not just the spots? Nobody told me that. What do I do when it stings?"
- ●If the doctor suggests going back on the pill, a different pill, the implant or a coil:
- ●Reaction: Anxious, speaking faster. "After what happened to Ruksana? I'm honestly scared of it." If the doctor explains her own risk with real numbers, including that Ruksana's clot followed a long flight and that a cousin is not close family: "So it's about five in ten thousand a year on that pill, and two if I'm not on anything? Okay. That's not what I'd built it up to be in my head." If the choice is left with her: "If it's the same one I was on before, I think I'd go back on it." If her fear is brushed aside: "With respect, she nearly died." About a different pill: "Is that one riskier for clots?" About the implant or coil: "My sister's implant made her skin terrible. Is there a coil without hormones?"
- ●If the doctor asks to see her skin on camera, or advises on makeup and skin care:
- ●Reaction: Declines, embarrassed. "I'd really rather not. I'm in a meeting room and the light's awful. Could I come in?" She is relieved when an appointment is arranged. On makeup: "I can't go out without it." She accepts oil free makeup removed every night. "My mum says it's the chocolate and takeaways. Should I cut them out?"
- ●If the doctor talks about referral, the review date, the dents or safety netting:
- ●Reaction: "Twelve weeks feels like forever. What if it gets worse? How long's the wait for the skin clinic?" On the dents: "Will they go? I don't want Dad's cheeks." She accepts an honest answer. If told only "come back if it gets worse": "Worse how? What would actually mean I need to ring you sooner?"
- ●If the doctor offers talking therapy or support for her mood:
- ●Reaction: Unsure. "It's my skin, not my head. If my skin got better I'd be fine." She is open to it if offered as an option rather than an instruction.

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Nadia has moderate to severe acne with early scarring, flared after stopping the combined pill, and asks for her friend's tablets. The skill is to explain honestly that isotretinoin is a specialist drug reached through a proper antibiotic trial, step up treatment today, correct how she uses her gel, and take her clot fear seriously because it decides the hormonal option.
- ●Model answer: explain the flare and its severity; prescribe a twelve week course of an oral tetracycline with adapalene with benzoyl peroxide used correctly over the whole area, with pregnancy and contraception advice; offer restarting her levonorgestrel pill as a choice, with absolute clot figures; arrange an in person examination soon; refer to dermatology for scarring and distress; give specific safety netting and a twelve week review.
- ●Also acceptable: the combined pill with a topical instead of an antibiotic, if she is told that an antibiotic course is normally needed before isotretinoin; azelaic acid instead of the gel if irritation is a problem; routine referral now or at the twelve week review with reasons; a different pill if its higher clot risk is explained.
Acne After Stopping the Pill, and Other Causes
- ●Combined pills lower ovarian androgen production and raise sex hormone binding globulin, so they suppress acne. Stopping can bring it back within weeks, often when cycles restart, typically on the lower face with deep tender lesions and a premenstrual flare.
- ●NICE Clinical Knowledge Summaries (CKS) advise asking about irregular periods, excess hair and scalp hair loss, and about medicines that cause acne, such as corticosteroids, androgens, lithium, ciclosporin and anabolic steroids.
- ●NICE NG198 on acne vulgaris now uses polyendocrine metabolic ovarian syndrome (PMOS) for what was polycystic ovary syndrome. Most people need no blood tests. Nadia's cycles are regular with no hirsutism, so none is needed.
Severity and Why She Needs Seeing in Person
- ●NG198 describes mild to moderate acne as up to 34 inflammatory lesions or up to 2 nodules, and moderate to severe as 35 or more lesions or 3 or more nodules. Four or five nodules at a time place Nadia in the moderate to severe range, and early scarring adds weight.
- ●Nodule count, comedones and scarring cannot be judged reliably over video, especially through makeup. Examine her in person, document scars and pigmentation, and take photographs for a referral. People with skin of colour are at higher risk of post inflammatory pigmentation and keloid scarring, which supports earlier, more active treatment.
- ●Ask about fever, joint pains, malaise and ulcerating, crusted lesions. Acne fulminans needs same day referral to the on call dermatology team.
The NG198 Ladder and Prescribing the Step Up
- ●First line courses last 12 weeks. For moderate to severe acne the options with an oral antibiotic are adapalene with benzoyl peroxide plus lymecycline or doxycycline, or azelaic acid plus lymecycline or doxycycline.
- ●Never use a topical antibiotic alone, an oral antibiotic alone, or a topical antibiotic with an oral antibiotic. Minocycline is not recommended because of lupus like reactions, pigmentation and hepatitis.
- ●Doses (BNF): lymecycline 408 mg once daily or doxycycline 100 mg once daily, swallowed with plenty of water. Both cause sun sensitivity and stomach upset, and a severe headache with visual change may be raised intracranial pressure, which needs same day assessment. They do not reduce pill effectiveness unless there is vomiting or diarrhoea.
- ●Adapalene with benzoyl peroxide goes thinly over the whole affected area each evening, because it treats microcomedones in clear looking skin. Start on alternate nights or wash it off after an hour to limit irritation. It bleaches fabric.
- ●Topical retinoids and tetracyclines must not be used in pregnancy. If her period is late, stop both and test.
- ●Benefit shows at 6 to 8 weeks. At 12 weeks, stop the antibiotic if clear, or continue it with the topical for up to 12 more weeks if improved. Beyond 6 months only in exceptional circumstances.
Hormonal Options and Putting Clot Risk in Proportion
- ●NG198 advises a combined pill in preference to a progestogen only pill if hormonal contraception is wanted. Progestogen only pills and implants with androgenic activity may worsen acne. For a woman worried about clots, restarting the levonorgestrel pill that cleared her skin is sound.
- ●MHRA figures: about 2 venous thromboembolisms per 10,000 women a year using no hormonal contraception; 5 to 7 on pills containing levonorgestrel, norethisterone or norgestimate; 9 to 12 with desogestrel, gestodene or drospirenone. All are lower than the risk in pregnancy.
- ●UKMEC 2025 rates a first degree relative with a clot as category 3 for combined hormonal contraception. A cousin is not first degree, and a long flight makes a clot provoked. Nadia has no migraine, does not smoke and has normal blood pressure and BMI, so the pill is suitable. The decision stays hers.
- ●Starting on days 1 to 5 needs no extra protection; otherwise use condoms for 7 days. Review at 3 months with blood pressure. Cyproterone with ethinylestradiol has a clot risk 1.5 to 2 times higher and is not for first line use.
When to Refer
- ●Same day: acne fulminans. Consultant dermatologist led team: diagnostic uncertainty, acne conglobata or nodulocystic acne.
- ●Consider referral for moderate to severe acne not responding to an oral antibiotic course, scarring, persistent pigmentary change, or persistent distress. Nadia has three of these now, so referring while the antibiotic runs is the stronger plan. Deferring to the twelve week review is defensible if examination shows no nodulocystic acne and she understands why.
- ●Past anxiety and her distress belong in the referral letter. Refer for mental health help if there is significant distress, severe depression, body dysmorphic disorder or self harm.
Isotretinoin and the Pregnancy Prevention Programme
- ●Isotretinoin is licensed for severe acne resistant to adequate systemic antibiotic and topical treatment, and is started only by a consultant dermatologist led team or an accredited GP with an extended role (BNF, MHRA). It must not be taken with tetracyclines. Dose is 0.5 to 1 mg/kg daily to a cumulative 120 to 150 mg/kg.
- ●Common effects are dry lips, skin and eyes, nosebleeds, and sun sensitivity. Liver function and lipids are monitored.
- ●Since 2023 the prescriber assesses mental health history and sexual function before starting and at every review. Past anxiety is not an automatic bar.
- ●It can seriously harm an unborn baby. Anyone who could become pregnant must not conceive during treatment or for 1 month after, with a negative test before each prescription. Acceptable contraception is an implant or intrauterine device in place for 4 weeks, or a hormonal pill or injection together with condoms. Condoms alone are not enough. Her old pill with condoms qualifies and helps her skin; the copper coil is hormone free.
Skin Care, Diet and Scarring
- ●NG198: a soap free cleanser twice daily, no oil based or comedogenic products, remove makeup every night, and no picking. There is no evidence for any particular diet. Treating active acne is the best protection against new scars.
- ●Post inflammatory pigmentation fades over months once new lesions stop, helped by daily sunscreen. If scarring persists a year after clearance, refer for scar treatment.
Common Mistakes in This Station
- ●Prescribing or promising isotretinoin, or refusing it with no route towards it.
- ●Combining oral and topical antibiotics, giving an oral antibiotic alone, or another cream for nodular acne.
- ●Never asking why she stopped the pill, so the clot fear and the hormonal option are missed.
- ●Treating her cousin's clot as a bar to the pill, or dismissing her fear without figures.
- ●Recommending a progestogen only method for her skin.
- ●Saying condoms alone satisfy pregnancy prevention.
- ●Missing the dabbing, the coconut oil and the picking.
- ●Grading severity from video, or never asking about mood and self harm.
- ●Safety netting limited to "come back if it gets worse".
