🧠 Why a structured consultation matters
An OTC recommendation is only as good as the information behind it. The same symptom, a headache, a cough, tiredness, can be trivial or the tip of something serious, and the only way to tell them apart safely is to ask the right questions every time. A structured consultation stops you missing a red flag, a drug interaction, or a group in whom a medicine is unsafe (children, pregnancy, other conditions). It also means that when you do refer, you can hand over a clear, useful picture.
WWHAM: the core information-gathering framework
WWHAM is the classic mnemonic for what to establish before recommending anything. Who is it for (the patient in front of you, or a child, an elderly relative, someone pregnant, each changing what is safe); What are the symptoms (in the patient's own words, then clarified); How long have they lasted (duration is one of the biggest steers toward referral); Action already taken (what they have tried, and whether it helped, tells you what to do next and avoids repeating a failed treatment); and Medication they take (the step that catches interactions and hidden conditions). The single most valuable habit is never skipping the M.
| Letter | WWHAM prompt | Why it matters |
|---|---|---|
| W | Who is it for | Age, pregnancy and frailty change what is safe and licensed |
| W | What are the symptoms | Defines the likely condition and any red flags |
| H | How long | Duration drives the decision to treat or refer |
| A | Action taken | Avoids repeating failed treatment; may itself be a referral cue |
| M | Medication | Reveals interactions and underlying conditions |
Other frameworks cover the same ground with different letters, for example ENCORE (Explore, No medication as an option, Care, Observe, Refer, Explain), which usefully reminds you that 'no medication' and self-care advice are legitimate, often correct, outcomes. Whatever the mnemonic, the goal is identical: enough information to recommend with confidence or refer with a clear reason.
General red flags that warrant referral
📌 Refer if you see
- •Symptoms that are severe, persistent (often beyond about 1 to 2 weeks), or getting worse despite appropriate treatment.
- •Unexplained weight loss, or blood in sputum, urine, vomit or stools.
- •Severe or sudden pain, or pain with alarm features.
- •A very young child, an older or frail person, someone pregnant or breastfeeding, or someone immunocompromised, where the threshold to refer is lower.
- •A symptom that could be a side effect of a medicine the patient already takes.
- •Anything that simply does not add up, or where you are uncertain.
⚠️ When in doubt, refer
In an exam scenario, and in real life, the safe answer is rarely to sell something regardless. If there is a red flag, a vulnerable patient, an unsafe interaction, or genuine uncertainty, referral to the GP, urgent care or A&E is the defensible action. A sale must never override safety, and 'refer' is frequently the correct single best answer.
💡 Document and safety-net
Even for a simple sale, briefly note significant advice or referrals, and always safety-net: tell the patient how long to expect symptoms to last, what would make things worse, and exactly when and where to seek further help if they do not improve. Good safety-netting turns a single interaction into ongoing protection.
Test yourself
What does WWHAM stand for, and which letter is most often skipped to the greatest risk?
Answer: Who is it for, What are the symptoms, How long, Action taken, and Medication being taken. The M (medication) is most often skipped, and missing it is how interactions and unsafe recommendations slip through.
A patient asks for a cough medicine. Give three pieces of information you must establish before recommending one.
Answer: Any three of: who it is for and their age; the nature and duration of the cough; whether there are red flags (blood, breathlessness, weight loss); what they have already tried; and what other medicines and conditions they have.
Why is 'no medication' sometimes the correct outcome of an OTC consultation?
Answer: Many minor conditions are self-limiting and best managed with self-care advice and safety-netting; recommending no medication (or referral) can be safer and more appropriate than making a sale.
What does it mean to 'safety-net' a patient, and why does it matter?
Answer: It means telling them how long symptoms should last, what would signal deterioration, and when and where to seek further help. It protects the patient after they leave, in case the condition is more serious than it first appeared.
