Patient Script
For the friend playing the patient role
Character Overview: You are Philip Whitcombe, a 45 year old delivery driver for a parcel courier. You drive a company van on a delivery round most days and have delivery targets to hit every day. You live with your partner Annette, who works on reception at a dental practice, and your son Zac, who is 14. You have had low back pain for six years, ever since a long drive and a house move. A scan showed some wear and a bulging disc at the bottom of your spine. A previous GP started pregabalin three years ago for the "nerve part" of the pain, and a locum increased it twenty months ago to one 300 milligram capsule twice a day. You registered at this practice a year ago. For months you have been taking more capsules than you are prescribed, because they smooth everything out, not just your back. They calm you, make you warm and heavy, and help you sleep. You ran out last night and have felt dreadful since. You are proud and quick to anger when you feel judged, and frightened of the withdrawal and of being labelled. You soften if the doctor is straightforward and does not accuse you. Your voice speeds up and gets sharp when you are cornered, and goes flat and quiet when you talk about Annette and Zac.
Opening Sentence: "Morning, doctor. I need my pregabalin prescription today, please. I've run out. Reception say it's too early, but the chemist short changed me, there weren't enough in the box."
History if Asked (Data Gathering Phase)
- ●The back pain: "About six years. It's mostly low down in the middle, with an ache into my left buttock sometimes. Not down my leg, and no weakness or numbness. Without anything it's about a five out of ten, and a seven after a day of driving. The scan said wear and a bit of a bulge. The amitriptyline knocked me out so I came off it."
- ●Why he is on pregabalin: "The old GP started it three years ago for the nerve part, and I've been on it ever since. A locum put it up to two a day, one morning and one night, about twenty months ago."
- ●The early requests and the chemist: "I've had to ask early three times now. I picked up this lot seventeen days ago and it's gone. I didn't count them at the counter, but they've gone, so someone's short changed me. The chemist at Alderney Road says it was the right amount. I think they've made a mistake."
- ●How he actually takes them (first answer): "Like it says. Morning and night."
- ●How he actually takes them (if asked again in a neutral, non blaming way, or if told that many people end up taking more than prescribed): "Fine. Some days I have an extra one in the afternoon when the back's bad." If asked how many he really has in a day: "Three. Four if it's a bad day. I'd never run out otherwise, would I." If the doctor accuses or lectures him, he gets angry and does not go beyond "Like it says" until the doctor eases off.
- ●What the extra ones do: "It isn't only the pain. It calms me down, I go warm and heavy and my head goes quiet. If I take two together in the evening I sleep like a log, and without them I lie awake. I take the extra before the pain gets bad now, to stay ahead of it."
- ●Symptoms now: "I took my last two about lunchtime yesterday. Last night I couldn't sleep, I was sweating through the sheets, my hands are shaking, my heart's going, my stomach's churning and my legs won't keep still. I feel on edge, I want to snap at everyone. I ran short for a day a few months ago and felt just the same, I thought I was having a heart attack. No fits, nothing weird like seeing things, and I'm thinking clearly."
Ideas, Concerns, Expectations
Gating note: Philip does not volunteer any of this. Each part comes out only when the doctor asks what he thinks is going on, what is worrying him, or what he was hoping for from today.
- ●Ideas: He thinks the chemist miscounted, and that his back is simply worse so he needs more of the tablets. "It's the back. It's got worse, so I need more to cope. The dose is just too low now, isn't it?"
- ●Concerns: He is frightened of the shaking and sweating getting worse, and of the back pain coming back with nothing to hold it. He is also afraid of being treated as a junkie, losing the prescription, and Annette and his boss finding out how much he really takes. "I'm not one of those people. I've never been in trouble in my life. I just need them to get through the day. And I can't have work finding out."
- ●Expectations: He wants a new prescription today, ideally for a full month, and perhaps a higher dose. "A month's worth, and could we put the dose up a bit?"
If Asked: Medical History and Medications
Gating note: Philip answers each of these plainly when the doctor asks about it.
- ●Other health problems: "Nothing else. I'm a worrier and have always been a bit anxious, but I've never seen anyone for it."
- ●Kidneys, lungs and fits: "No kidney trouble. No asthma or chest problems. I've never had a fit or a blackout."
- ●Other medicines: "Only the pregabalin. I take ibuprofen now and then. Nobody else prescribes for me, just this surgery."
- ●Allergies: "None."
- ●Alcohol: "About two pints of lager four nights a week, and more on a Saturday, maybe five or six. I have a pint with my evening tablets. It hits harder with a drink, to be honest." This works out at about 28 units a week. If asked about his drinking being a problem: "No, it's just socially, with the footy."
- ●Other tablets and drugs: "I buy co-codamol from the chemist, three or four a day, a packet every week or so, from different shops so they don't look at me funny. No sleeping tablets, no street drugs, and I've never bought pregabalin online or off anyone. A mate offered once and I said no."
- ●Mood: "Low sometimes, and snappy. Sleep's rubbish without the tablets. I'm not depressed."
Social History and Lifestyle Impact
- ●Work: Delivery driver, driving a van for about six hours a day on his round. He says the afternoon extra capsule makes him "a bit dozy" and he nearly missed a junction last month. No one at work knows he takes pregabalin.
- ●Home: Annette has started counting the boxes and they have rowed about it. He has tripped on the stairs twice after his evening capsules. He would agree for Annette to be involved if asked, but fears she will be angry.
- ●Availability to be seen: At the depot today and free from three o'clock, or any time tomorrow morning. He could come to the surgery.
If Asked: Associated Symptoms
Gating note: Philip answers these only when asked. Every one is negative unless stated.
- ●If asked about chest pain or breathlessness: "No pain in my chest, just my heart racing. No breathing trouble."
- ●If asked about confusion, hallucinations or fits: "No. My head's clear."
- ●If asked about very low mood, feeling hopeless or not wanting to be here: "Fed up, yes. Not hopeless. No, I would never do anything."
- ●If asked about bladder, bowel, numbness around the bottom, weakness or fever: "No. It's the same back, nothing new."
Responses to Management (The Negotiation Phase)
- ●If the doctor says he cannot issue a full early supply:
- ●Reaction: Angry. "So I'm just meant to suffer? I shake, I can't sleep, I can't work. I've done nothing wrong." If the doctor stays calm, acknowledges how bad he feels and explains what can be done today: "Right. So what can I have today, then?" If lectured or pressed on the numbers, he repeats that the chemist short changed him.
- ●If the doctor suggests a short supply, weekly collection or close checks:
- ●Reaction: Resentful, then accepts. "Like a kid? Like I'm one of those on a methadone script?" If told it is for safety while his treatment is sorted out, and not a punishment: "Fine. How long for?" He asks if a month's supply is ever possible again.
- ●If the doctor explains that taking more than prescribed has led to his body depending on the tablets, and suggests a slow reduction:
- ●Reaction: Frightened. "If I cut down I'll be in bits, like last night. And what about my back?" If told the reduction is gradual, in fixed small steps at a pace he helps set, and that the back will be managed another way: "How long would it take? Can I stop if it gets too much?" He agrees to try if he stays in control of the pace.
- ●If the doctor suggests a referral to a drug and alcohol service, or addresses alcohol and co-codamol:
- ●Reaction: Defensive. "I'm not an addict. That's for people on the streets. Will work be told?" If told the service helps people on prescribed tablets and is confidential: "Okay, I'll go if it's not a big deal." On drinking and co-codamol: "I can cut the co-codamol out. The pints, I'll think about it." Accepts the risk once told that alcohol with pregabalin can slow breathing.
- ●If the doctor asks about work and driving, or about involving Annette:
- ●Reaction: Worried. "I need the van for my job." If told not to drive when drowsy and that driving while impaired is an offence: "I'll stop having the afternoon one." On Annette, quietly: "She'll go mad. But yes, all right, she can know."
- ●If the doctor gives safety netting or arranges a review:
- ●Reaction: Wants specifics. If told only "come back if worse": "Worse how? I'm already shaking. When do I ring 999?" He repeats back clearly when given specific symptoms and where to go. He agrees to be seen in person today at three or tomorrow morning, and asks what the review is for.

Clinical Learning Points
The Core Dilemma and the Model Plan
- ●Philip is 45, has had chronic low back pain for six years, and takes pregabalin 300 mg twice a day. He has asked for an early supply three times in two months, blames the pharmacy, and becomes angry when challenged. The station tests whether the candidate can recognise gabapentinoid dependence behind a request that sounds like a dispensing error, keep him safe from withdrawal and overdose, and start a planned reduction without a fight.
- ●The model plan has seven parts. Take a non accusing history that finds the real daily use, the withdrawal symptoms and the alcohol and opioid use. Check the supply with the pharmacy and the record. Do not issue an early or larger supply on the story alone. Bridge him safely with a short supply at the prescribed dose, or see him in person first. Offer drug and alcohol service support. Agree a gradual reduction in fixed steps once he is stable. Give specific safety netting and review within about a week.
- ●Acceptable alternatives: seeing him face to face today and prescribing at that visit; a short supply of a few days or one week dispensed in instalments; or asking the drug and alcohol service to lead the reduction, with the practice continuing to prescribe and review. Not acceptable: a full early supply, a dose above the licensed maximum, switching to gabapentin, adding an opioid, or stopping abruptly with no plan.
Recognising Gabapentinoid Dependence
- ●Pregabalin is licensed for epilepsy, neuropathic pain and generalised anxiety disorder. It was reclassified as a Class C controlled drug and placed in Schedule 3 in April 2019, because of reported misuse and dependence. Healthcare professionals should evaluate people for a history of drug abuse before prescribing, and watch for signs of misuse and dependence.
- ●Features here: 56 capsules lasting about 17 days (three to four a day against two prescribed); dose creep; taking extra before the pain builds; use for calm and sleep as well as pain; a withdrawal syndrome when the supply runs out; and an external explanation.
- ●The British National Formulary (BNF) gives 600 mg a day as the maximum for adults, so his estimated use of about 900 to 1,000 mg is above it. Do not prescribe above that maximum to match what he has been taking.
- ●NICE guideline NG215 (April 2022) says dependence is an expected effect of these medicines, and that clinicians should avoid language that apportions blame. The Medicines and Healthcare products Regulatory Agency (MHRA) updated its advice in January 2026 to strengthen warnings on addiction, dependence and withdrawal. Prescribers should counsel on the risks, use non judgemental language, and offer a tailored reduction schedule.
History: Getting the Truth Without a Fight
- ●Open with neutral wording, for example "many people find they end up taking a bit more than planned, how has it been for you?". An accusing question produces more denial and more anger.
- ●Ask how many capsules he takes on a typical and a bad day, the effects he gets, the last dose and any previous episodes of running out.
- ●Ask about alcohol (about 28 units a week here), over the counter co-codamol (three to four a day), benzodiazepines, street drugs and online pregabalin. Ask about other prescribers, driving, falls, breathlessness, kidney disease, past seizures, and mood including thoughts of self harm.
- ●Explore his ideas, concerns and expectations: he fears withdrawal, the pain returning, and being labelled. Check briefly for new back red flags; the task is not to reinvestigate the back.
Safe Short Term Management
- ●He last took capsules yesterday lunchtime and is already in early withdrawal. NICE NG215 advises against stopping a medicine abruptly unless there are exceptional medical circumstances, such as serious side effects, and the MHRA also advises against abrupt cessation of pregabalin.
- ●Acceptable routes: issue a short supply (for example seven days) at the prescribed dose of 600 mg a day, or arrange a same day face to face review and prescribe afterwards. Either is safer than a refusal that leaves him with no plan, or a full month that he can again overuse.
- ●A face to face review within a day or two should include pulse, tremor, blood pressure, mood and sedation, with bloods for kidney function (pregabalin is cleared by the kidneys) and liver function given his drinking.
Controlled Drug Prescribing Safeguards
- ●A Schedule 3 prescription must state the dose, form, strength and total quantity (in words and figures for the quantity) and carry a valid signature. It is valid for 28 days from the date on it. It cannot be issued as a repeatable prescription.
- ●The Department of Health strongly recommends that the maximum quantity of Schedule 2, 3 or 4 controlled drugs prescribed should not exceed 30 days, with the reasons documented if longer. Given his early requests, a much shorter supply is justified.
- ●Instalment prescribing is allowed for Schedule 3 drugs. It must state the dose, the instalment amount and the interval between supplies.
Planned Reduction
- ●NICE NG215 recommends discussing withdrawal when problems associated with dependence have developed or the harms outweigh the benefits. Agree the pace with him.
- ●For gabapentinoids, NG215 advises reducing by a fixed amount at each step (not a proportionate reduction, which is the approach for opioids, benzodiazepines, Z drugs and antidepressants). It gives no step size, and the CKS pregabalin page (June 2026) says only to stop gradually, over at least a week. Step size is therefore local practice: a common approach is to stabilise on the prescribed dose, then reduce by modest fixed steps every one to two weeks, pausing if symptoms become intolerable.
- ●The first goal can be dose reduction with review rather than complete withdrawal.
- ●Symptoms that start soon after a reduction, or are new or more intense than before, suggest withdrawal rather than relapse of pain or anxiety.
- ●Refer or encourage self referral to the local drug and alcohol service, particularly because of his alcohol use. Alcohol use at this level also merits a brief intervention and a screening tool such as AUDIT (Alcohol Use Disorders Identification Test).
Alcohol, Opioids, Driving and Mood
- ●The MHRA warns of potentially fatal interactions of pregabalin with alcohol and with other central nervous system depressants, particularly opioids. In February 2021 it also reported severe respiratory depression with pregabalin, in some cases without an opioid, and advised caution in people with respiratory disease, renal impairment, older age or other sedatives.
- ●Advise him to stop the over the counter co-codamol and cut his drinking, and to avoid alcohol close to his capsules.
- ●Advise him not to drive when drowsy or unsteady. Driving while impaired by a medicine is an offence, and he drives a delivery van for work.
- ●Screen mood, sleep and anxiety, ask directly about thoughts of self harm, and offer follow up. The BNF lists suicidal behaviours among pregabalin side effects.
The Back Pain
- ●NICE NG59 (low back pain and sciatica) says not to offer gabapentinoids or antiepileptics for managing low back pain. Pregabalin has no recommended place in his back pain, so the tablets are reduced and not increased. It also advises against opioids for chronic low back pain, so the co-codamol should stop.
- ●Recommend exercise, staying active, physiotherapy or a group exercise programme, and self management.
Safety Netting and Follow Up
- ●Call 999 for a seizure, confusion or hallucinations, slow or shallow breathing, or being very hard to wake. Same day contact is needed for worsening shaking, chest pain or palpitations that do not settle, severe agitation, or vomiting that stops him taking his capsules.
- ●Tell him not to take extra capsules or buy pregabalin online.
- ●Review within about a week, with a named person to contact if problems occur.
- ●With his consent, involve his partner.
Common Mistakes in This Station
- ●Issuing the early supply, or a higher dose, because the patient is angry or blames the pharmacy.
- ●Refusing everything and leaving him in withdrawal with no plan, or stopping the tablets completely.
- ●Accusing language such as addict or drug seeker, which ends the history.
- ●Not asking how many capsules he really takes, or what else he takes, so missing the alcohol and co-codamol.
- ●Switching to gabapentin or adding an opioid for the back pain.
- ●Issuing a month at a time to a person with early requests, or forgetting the Schedule 3 prescription requirements.
- ●Vague safety netting such as "come back if worse".
- ●Forgetting driving, mood and the offer of drug and alcohol service support.
