What Can a Pharmacist Treat? A Plain Guide to Where to Go First

What can a pharmacist treat? More than most people expect: coughs, colds, skin and eye complaints, seven common infections on the NHS, contraception, blood pressure checks and questions about your own medicines. No appointment, no referral. This guide maps your problem to the right place — pharmacy, GP, NHS 111 or 999.

Why the pharmacy is a sensible first stop

Two thoughts stop people coming in. The first is that the problem is too small to bother anyone with. The second is that it is too serious for a shop on a high street. Both send people to the wrong place — one to a GP appointment they did not need, the other to a three-week wait for something we could have sorted that morning.

A community pharmacy in England is not only a dispensary. Every pharmacy in the country has to provide a set of core NHS services under its contract, and answering questions about your health and your medicines is one of them, as is telling you plainly where else to go when the answer is not here. On top of that, pharmacies can sign up to deliver extra NHS services, which is why one chemist offers vaccinations and blood pressure checks while another down the road does not.

The practical difference is the door. You do not need to be registered with us, you do not need to live nearby, and you do not need to ring ahead. You walk in and ask. Most conversations at our counter last a couple of minutes and end with either a treatment off the shelf or a clear sentence about who you should see instead.

That second outcome matters as much as the first. A pharmacist who tells you honestly that your symptom needs a GP has saved you time rather than wasted it, and you can find out in five minutes rather than five days.

What can a pharmacist treat without a prescription?

Start with the everyday things, because this is the largest group by far and the one people underestimate. Our pharmacists can assess and advise on coughs, colds and sore throats, blocked noses, hay fever, headaches and everyday aches and pains, indigestion and heartburn, constipation and diarrhoea, thrush, cold sores, mouth ulcers, athlete's foot, head lice, threadworms, warts and verrucas, mild eczema and dry skin, teething, nappy rash, styes and sore eyes, travel sickness and period pain. For all of these a pharmacist can recommend a treatment that does not need a prescription at all, and can tell you when what you are describing has stopped sounding like a minor illness.

That last part is the skill. Choosing a cough medicine is easy. Recognising the cough that has gone on six weeks, or the heartburn in someone who is also losing weight, and saying so out loud, is the bit you cannot get from a shelf or a search engine.

Then there is the NHS Pharmacy First service, which lets a pharmacist assess and, where it is right to do so, supply prescription-only treatment including antibiotics for seven common conditions without a GP appointment. Each of the seven has its own NHS age range, and those ranges are strict — being outside one is the most common reason we have to send someone on. We have not repeated the detail here because our full guide to Pharmacy First sets out the seven conditions and the age criteria in a table, and our Pharmacy First service page explains how a consultation runs.

Advice about a medicine you are already taking is its own category, and it is free, unlimited and available to anyone. Bring the box. We can tell you whether the tablet you were handed last week clashes with the hay fever remedy you were about to buy, what to do about the dose you missed, whether the dizziness started when the dose changed, and whether something you have been prescribed can be taken in pregnancy or while breastfeeding. It makes no difference whether the prescription came from us.

Minor injuries sit at the edge of what we do, and the edge is worth knowing. We can look at a small cut, a graze, a bruise, a minor burn or a sprain you can still put weight on, clean and dress it, advise on pain relief, and say whether it needs a tetanus booster. What we cannot do is close a wound, take an X-ray or rule out a fracture, so anything that gapes open, bleeds heavily, involves an eye, or leaves you unable to use the limb goes to an urgent treatment centre or A&E.

Services you may not know a pharmacy provides

Beyond treating illness, a good deal of NHS care has quietly moved into pharmacies over the past few years, and most people have not been told.

• Emergency contraception. We supply it free on the NHS, with no appointment and no need to see a GP first. It works better the sooner it is taken, so come in as early as you can. We cannot supply it in advance to keep at home.
• Ongoing contraception. A pharmacist can start you on the contraceptive pill or continue the one you are on, with the checks done here rather than at a surgery.
• Blood pressure checks. If you are 40 or over and have not been checked recently, the NHS check is free and takes about five minutes. High blood pressure has no symptoms at all, which is exactly why it goes unfound for years. Our NHS blood pressure check page explains what happens to the reading afterwards.
• Vaccinations. Seasonal flu on the NHS for eligible adults aged 18 and over, COVID-19, MenB, chickenpox, and a full travel clinic. We are a registered Yellow Fever Vaccination Centre, which not every pharmacy is.
• Help with a medicine you have just been started on. If your new medicine is for certain long-term conditions, the NHS New Medicine Service gives you follow-up conversations with a pharmacist over your first few weeks.
• Stopping smoking, weight management and ear wax removal, plus safe disposal of medicines you no longer need — bring old or out-of-date boxes back to any pharmacy rather than putting them in the bin.
• An emergency supply of a regular medicine. If you have run out of something you have been prescribed before and cannot get a prescription in time, the law allows a pharmacist to supply a limited amount after interviewing you. It is a judgement call, not a right, and most controlled drugs are excluded, so it is a safety net rather than a plan.

Not every pharmacy offers every one of these. The NHS keeps a plain summary of how pharmacies can help, and it is worth a look before you assume something needs a doctor.

What a pharmacist cannot do

This is the part nobody writes down, and it is the most useful thing on this page. Knowing where the line sits saves you a wasted journey and, occasionally, something worse.

We cannot investigate. There is no blood test here, no X-ray, no scan, no lab. If the honest answer to your symptom is "it depends what the test shows", the pharmacy cannot get you that answer. Unexplained weight loss, a lump, a mole that has changed, persistent tiredness, a cough that has lasted weeks, blood where there should not be blood — all of those need a GP who can examine you and order tests.

We cannot see your whole record. We can see what we have dispensed, and with your permission a summary of your medicines and allergies. We cannot see your GP's notes, your test results or your hospital letters, so we are working with less than your surgery has.

We cannot issue a fit note. This one surprises people, because the law did change: since 1 July 2022 pharmacists, nurses, physiotherapists and occupational therapists have been able to certify fit notes as well as doctors. But that applies to those working inside general practice or hospital teams. Community pharmacies do not have access to the official form and fit notes are not part of the NHS services community pharmacy provides, so for a sick note you need your GP practice.

We cannot prescribe whatever you ask for. A prescription-only medicine can only leave this pharmacy on a prescription, under a defined NHS pathway such as Pharmacy First, or where a pharmacist prescriber is working within their own area of competence. Our superintendent pharmacist, Poonam Pankhania, is an independent prescriber, and that is still a bounded thing, not a blank cheque. "My friend had these and they worked" is not a route to antibiotics, and a pharmacist who says no to that is doing the job properly.

We cannot overrule your prescriber. We cannot add a medicine to your repeats, change a dose your GP set, or make a referral to a hospital specialist. What we can do is flag a problem to your practice with your consent, which is usually faster than you chasing it.

We cannot take over a long-term condition. Asthma, diabetes, heart disease, thyroid problems and mental health conditions need monitoring, results and review over years. We support that work — reviews, supplies, questions between appointments — but we do not replace it.

Pharmacist, GP, 111 or 999?

Use the table below to find the row closest to your situation. If two rows fit, take the more urgent one.

If you are torn between two rows, that uncertainty is itself the answer: NHS 111 exists for urgent problems that are not life-threatening, answers around the clock, and nobody there will think you have wasted their time.

Walking in to our pharmacy in Harrow

We are at 160 Pinner Road, Harrow HA1 4JJ, open Monday to Friday from 9am to 6pm and Saturday from 9am to 1pm, closed on Sunday. You can reach us on 020 8863 6338, or use our contact page if you would rather write than ring. People walk down to us from North Harrow, come across from West Harrow, drop in on the way through Harrow town centre, and travel over from Rayners Lane, and none of them need an appointment or a referral to ask a pharmacist a question.

Say at the counter what is wrong, in as few words as you like. If it needs privacy, ask, and we will move the conversation somewhere you cannot be overheard. If it is something we can treat, you will usually walk out with it. If it is not, you will walk out knowing exactly who to contact and how soon, which is worth the trip on its own.

One habit worth forming: ask before you assume. The commonest thing we hear after a long GP wait is "I didn't know you could do that here." Now you do.
