Prescription writing practice

Write real prescriptions and have every line marked

Simulated patients with real kidneys, real allergies and real drug charts. You choose the drug, the dose, the route and the words on the label, and a rules engine built on the drug database tells you exactly what was unsafe and why.

  • Marked against dose ranges, renal thresholds, allergy records and interaction data, not an AI guess
  • Instructions and monitoring plans are checked too, because the label is part of the prescription
  • A single critical error fails the attempt, the way an unsafe script would be pulled on a ward

How a session works

  1. 1

    Read the chart

    Age, weight, renal function, allergies, current medicines and the presenting problem, as on a real drug chart.

  2. 2

    Write the prescription

    Search the formulary, set dose, unit, route, frequency and duration, and write the patient instructions and monitoring plan.

  3. 3

    Submit for marking

    Every line is checked against the case rules and the drug database: dose bands, renal adjustment, allergies, interactions, daily maximums.

  4. 4

    Read the reasons

    A score by domain, a critical-error flag, and a line-by-line explanation of what was wrong and what the safe choice was.

Write one now

A 72-year-old man with pneumonia, a penicillin allergy and warfarin for a mechanical valve. Prescribe his antibiotic and his analgesia, and see what the engine finds.

Write the prescription

The full prescription pad with the live formulary search, marked on the server by the same rules as a real attempt. Takes about five minutes.

Start the scenario

See a marked report first

A different scenario, already attempted with three common mistakes, showing the score by domain, the critical findings and every explanation.

What gets marked

Drug choice

Expected drugs and acceptable alternatives, with contraindicated agents flagged as critical.

Dose, route, frequency, duration

Each checked against the range the case author set, with weight-based dosing where it applies.

Renal and hepatic adjustment

Dose ceilings below an eGFR threshold, and the formulary's own renal bands for every drug you prescribe.

Allergies

The patient's allergy record is cross-checked against every drug, including class cross-reactivity such as penicillins.

Interactions

Prescribed lines are checked against each other and against the patient's current medicines using the interaction database.

Instructions and monitoring

Required counselling points and monitoring plans, such as an INR check or renal function, earn marks when present.

Courses that use this module

Each of these courses builds this practice into its modules, next to the teaching it tests.

  • Therapeutic Drug Monitoring and Prescribing Calculations

    For final-year medical students preparing for finals and the Prescribing Safety Assessment (PSA), final-year pharmacy students, and foundation doctors. Topics: prescribing calculations, applied pharmacokinetics and therapeutic drug monitoring of narrow-therapeutic-index drugs, and interpreting potassium, sodium, renal, thyroid and liver results. UK practice, BNF dosing and NICE-style guidance. Pharmacy students do not sit the PSA.

  • Adverse Drug Reactions and Pharmacovigilance

    For final-year medical students preparing for finals and the PSA, final-year pharmacy students and foundation doctors. Covers what counts as an ADR, A to F and DoTS classification, WHO-UMC and Naranjo causality, severity versus seriousness, type A reactions, allergy, organ-specific harm, and Yellow Card reporting. Every module closes with a quiz. Practice includes prescribing scenarios, timed OSCE stations and ADR cases to assess and report.

  • Safe Prescribing in Special Populations

    Prescribing where standard adult doses cause harm, in UK practice with British National Formulary dosing, for final-year medical students preparing for finals and the Prescribing Safety Assessment, final-year pharmacy students and foundation doctors. It covers renal and hepatic impairment, pregnancy and breastfeeding, weight-based dosing in children, polypharmacy and deprescribing in older people, and serious interactions and adverse drug reactions.

  • Pain, Neurology and Mental Health Prescribing

    Pain, neurological and psychiatric prescribing in UK practice, for final-year medical students preparing for finals and the Prescribing Safety Assessment, final-year pharmacy students and foundation doctors. It covers the analgesic ladder, opioid and NSAID safety, neuropathic pain, epilepsy and valproate risk, migraine, Parkinson's disease, depression, lithium, anxiety and sleep, psychosis, rapid tranquillisation and delirium. Doses follow the British National Formulary.

It covers stepwise asthma management, inhaler technique, acute severe asthma in adults and children, COPD inhaled therapy and infective exacerbations, controlled oxygen and type 2 respiratory failure, and respiratory examination, chest radiographs and bronchiolitis.

  • Acute Medicine, Poisoning and Emergencies

    Acute medicine and emergency prescribing in UK practice, for final-year medical students preparing for finals and the Prescribing Safety Assessment, final-year pharmacy students and foundation doctors.

It covers choosing and intensifying type 2 diabetes therapy, insulin regimens and sick-day rules, hypoglycaemia, the variable rate insulin infusion, DKA and HHS, thyroid disease, corticosteroids and adrenal crisis, and calcium and sodium disorders. Dosing follows the British National Formulary.

Questions

Is the marking done by AI?
No. Prescriptions are marked by deterministic rules and the structured drug database, so the same prescription always gets the same marks. AI is used only to explain findings afterwards, never to create or override them.
Can I try it without an account?
Yes. One scenario is open to everyone on this page and at /try. Create a free account to keep the result and unlock the rest of the bank.
Which plan includes it?
The prescription lab is part of Student Pro and above. Every new account starts with a Student Pro trial, no card required, so it is available from day one.
Where do the scenarios come from?
Faculty-authored and AI-drafted scenarios that are reviewed before publication. Each carries its own rules for expected drugs, doses, monitoring and contraindications.
