Flu Treatment Online & Online Prescription

Key facts

Treated online: Yes, usually. Video assessment, with a prescription when appropriate.
Flu antivirals work best when started within about 48 hours of symptoms, so early assessment matters.^[4]
Flu typically lasts about a week, though the cough and tiredness often linger one to two weeks longer.
A fever that settles and then returns days later can mark a secondary bacterial infection and deserves same-day review.
For severe breathlessness, chest pain or confusion, call 112.

Check before you book

If you are breathless, have chest pain, feel confused or unusually drowsy, or are passing very little urine, arrange urgent in-person care instead of a video appointment. The same applies if you are pregnant, over 65 or living with a serious long-term condition and getting worse rather than better. For severe breathlessness, chest pain or confusion, call 112.

Can an online doctor treat flu?

Yes

Flu: usually treated online.

Yes. Mobi Doctor, an online healthcare service with licensed doctors, can assess flu by video, usually the same day: confirming the diagnosis, screening for complication risk, and prescribing antiviral treatment after assessment where it genuinely helps.^[1] Severe breathlessness, chest pain or confusion needs emergency care, so call 112 rather than booking a video appointment, and availability of antivirals varies by country.

Flu is also the illness where staying on the sofa is a clinical virtue: a video consultation spares you a feverish trip to a waiting room and spares the waiting room your virus, without losing the two things that matter, a proper risk assessment and a concrete plan.

How an online consultation helps with flu

Timing matters with flu:

antiviral medicines work best when started within about the first 48 hours of symptoms.^[1] A same-day video appointment protects that window while you stay home and keep your germs out of a waiting room.

Risk-group check:

the doctor establishes whether pregnancy, age over 65, asthma, COPD, heart, kidney or liver disease, diabetes or a weakened immune system puts you in a group where flu deserves closer attention than "wait it out".

A concrete plan for the week:

what to take and when, how much to drink, roughly when the fever should break, and the specific warning signs that should bring you back or straight to in-person care.

Protecting your household:

concrete advice for homes with pregnant, elderly or chronically ill members, the people for whom your flu is a much bigger deal than it is for you, including what to watch for in them.

What the doctor checks in an online flu consultation

A flu consultation confirms the picture fits influenza, checks your risk, and watches your breathing. In a flu consultation the doctor will typically check:

When symptoms started, ideally to the hour: the antiviral window of about 48 hours is real, and timing changes the options.^[1]
Whether the pattern fits flu: sudden onset, fever, muscle aches, headache and exhaustion, rather than a nose-centred cold.
Your risk group: pregnancy, age over 65, asthma, COPD, heart, kidney or liver disease, diabetes, a neurological condition or a weakened immune system.
Your breathing on camera, plus your temperature and any pulse-oximeter reading if you have them; both sharpen the assessment, though neither is required.
Vaccination status this season.
Your regular medicines and conditions, and how well controlled they are.
Who you live with, since a vulnerable household changes the advice.
A red-flag screen: breathlessness, chest pain, confusion, poor urine output, or a fever that returns after settling.

What is the difference between flu and a cold?

Flu starts abruptly, often within hours, with fever, muscle aches, headache and exhaustion that stops you working. A cold builds over a day or two, stays centred on a runny or blocked nose, sneezing and a scratchy throat, and usually leaves you able to carry on. Speed and severity are the giveaway.

Flu versus a cold, at a glance
Feature	Flu	Cold
How it starts	Suddenly, over hours	Gradually, over a day or two
Fever	Common, often high	Rare or mild in adults
Muscle aches	Marked, whole body	Slight
Exhaustion	Severe: bed, not desk	Mild
Sneezing, runny nose	Sometimes, in the background	The main event
Able to carry on?	Rarely	Usually
Typical course	About a week, then lingering cough and tiredness	A few days to a week

Why the difference matters

A cold needs nothing but self-care and patience. Flu changes decisions: it is the illness where antiviral treatment exists, where risk groups need prompt assessment, and where complications such as pneumonia are worth actively watching for rather than discovering late.

Is my flu suitable for online care?

Most flu is safe to assess and plan online; a minority needs in-person care. The table below shows how doctors sort flu presentations into self-care, antiviral treatment where it is appropriate, and referral.

Flu presentation	Likely first step	Suitable for online care?	When referral or in-person care is needed
Otherwise healthy adult, typical flu, seen early	Confirm flu, self-care plan, consider antiviral if early and appropriate	Usually yes	If breathlessness, chest pain, confusion or dehydration appears
Risk group (pregnant, over 65, chronic condition) within 48 hours	Prompt assessment; antiviral where criteria and country rules allow^[1]	Usually yes, promptly	Deterioration, or the underlying condition destabilising
Fever that returns after improving, or breathless on mild effort	Assess for a bacterial complication such as pneumonia	Sometimes, for triage	Chest examination or X-ray in person
Severe breathlessness, chest pain, confusion, very little urine	Emergency care	No	Call 112 immediately
High fever with stiff neck, new rash or intolerance of light	Emergency care (possible meningitis)	No	Call 112 immediately

Availability and prescribing vary by country; your doctor confirms what applies where you are.

Who should see a doctor promptly about flu?

Anyone pregnant, aged over 65, or living with a chronic condition such as asthma, COPD, heart, kidney or liver disease, diabetes, a neurological condition or a weakened immune system, should consult a doctor within the first day or two of flu symptoms. These groups benefit most from early antiviral treatment and closer monitoring.

The reason is complication risk: in these groups flu more often turns into pneumonia or destabilises the underlying condition, and early treatment plus a clear monitoring plan changes outcomes. One sign matters for everyone, risk group or not: a fever that settles and then returns days later can mark a secondary bacterial infection, and deserves same-day review.

Antivirals, antibiotics and the vaccine: an honest guide

Antiviral medicines

Flu antivirals (oseltamivir-type medicines) are real but modest: started early, ideally within 48 hours, they typically shorten the illness by around a day and are mainly reserved for people at higher risk or with severe illness.^[1]^[4] They are doctor-assessed, not routine, and availability and prescribing rules vary between EU countries; the doctor will tell you plainly what is possible where you are.

The assessment itself weighs four things: how many hours since symptoms began, whether you belong to a risk group, how severe the illness looks on camera, and what your country's rules allow. If you fall outside the window or the criteria, the doctor will say so and put the effort into the plan that actually helps, symptom control and monitoring.

Antibiotics and the flu vaccine

Antibiotics do not work against flu; it is a viral illness, and antibiotics are only prescribed when there are signs of a bacterial complication such as pneumonia, because unnecessary courses fuel antibiotic resistance.^[3] Looking further ahead, the annual flu vaccine remains the best protection and is recommended across Europe for risk groups and health workers;^[2] in many EU countries you can arrange it at a local pharmacy, and the doctor can advise whether you should.

How long does flu last?

Flu typically lasts about a week: the fever and worst aches peak in the first two to three days and settle within seven, while the cough and tiredness often linger one to two weeks longer.^[5] Go back to work once the fever has been gone a full day and you can function.

That lingering phase deserves a word: a dry post-flu cough alone, slowly improving, is expected and does not need antibiotics. What breaks the pattern, and warrants review, is deterioration after improvement, breathlessness, or exhaustion that is getting deeper rather than lifting in week two.

When it might be something else

COVID-19 and other winter viruses

Flu, COVID-19 and RSV overlap heavily, with fever, cough, aches and exhaustion, and no doctor can reliably separate them by symptoms alone. A rapid test, sold by pharmacies across Europe, is the only dependable way to tell, and the result is worth having: it changes isolation advice and, in risk groups, treatment options. Self-care is the same either way.

Early pneumonia

Suspect a bacterial complication rather than flu itself when someone gets worse after getting better, becomes breathless on mild effort, develops one-sided chest pain on breathing, or coughs up rust-coloured phlegm. This is the scenario the safety-netting exists for: same-day assessment, in person where examination is needed.

When fever is not flu

A high fever with a severe headache, a stiff neck, a new rash, or intolerance of light is not a flu pattern; those features raise meningitis and need emergency care immediately, not a video appointment. Call 112 if they appear.

Special situations

Flu in pregnancy

Pregnancy makes flu complications more likely at every stage, which changes two decisions: consult promptly rather than waiting it out, and take prevention seriously, because flu vaccination during pregnancy is recommended across Europe and protects the baby in the first months too. Antiviral treatment can be considered in pregnancy; that judgement belongs to the doctor, made case by case after assessment.

Flu when you are over 65

Older adults do not always run textbook fevers; flu can instead show as new confusion, unsteadiness, falls or simply "not themselves", sometimes with a normal thermometer reading. Families often spot it first. The threshold for a same-day review is lower here: deterioration in an older adult with flu is a today problem, not a tomorrow one.

Flu while travelling

Flu seasons differ by hemisphere: Europe's winter peak has a southern-hemisphere mirror in the middle of the year, and travellers meet flu out of season more often than they expect. A video consultation works wherever in Europe you are: English-speaking assessment, a prescription to a nearby pharmacy in most EU countries, and honest advice on when a local clinic is the better option. If in-person care is needed, a European Health Insurance Card (or its travel-insurance equivalent) smooths access to public healthcare across the EU, worth locating in your luggage before you are ill enough to need it.

Treatment options for flu

What you can do yourself

Rest is genuinely part of the treatment, so plan for several days, not one. Drink regularly (fever steadily drains fluid out of you), take paracetamol or ibuprofen for fever and aches, and stay home while feverish so you do not hand the virus on. Ventilate shared rooms, wash hands often, and keep your distance from household members in risk groups while you are at your most infectious in the first days; separate towels and, if you are caring closely for someone vulnerable, a mask in shared rooms are simple and worthwhile.

Managing the fever properly

Take paracetamol or ibuprofen at the intervals on the packet rather than waiting for the fever to spike; steady control feels dramatically better than peaks and troughs, and the two can be alternated if one alone is not enough, within each medicine's daily limit. Judge hydration by your urine: pale means you are winning, dark and scanty means drink more. Shivering under a duvet mid-fever is fine; what matters is fluid in and warning signs watched.

Prescription treatment

A prescription is never issued without a consultation. Where the assessment supports it, for higher-risk patients, severe symptoms or early presentation, the doctor can prescribe antiviral treatment and arrange follow-up to check you are on the right track. If your story or your recovery suggests a bacterial complication, they will either prescribe an antibiotic where the signs support it or direct you to in-person care for a chest examination first.

When we treat flu online, and when we refer you

We treat online: typical flu in otherwise healthy adults who need a plan and safety-netting; risk-group patients seen early enough to consider antiviral treatment; post-flu cough and tiredness that are slowly improving; and advice for protecting a vulnerable household.

We refer or redirect you: severe breathlessness, chest pain, confusion or very low urine output, which are emergencies; a fever with a stiff neck, new rash or intolerance of light, which raises meningitis and is an emergency; signs of pneumonia that need a chest examination in person; and older adults or pregnant patients who are deteriorating, where a lower threshold for in-person review applies. In those cases the consultation gets you to the right level of care quickly, not a prescription in place of one.

When to get in-person care

Seek urgent in-person care if you become breathless, cough up blood, cannot keep fluids down, are passing very little urine, or if fever returns after you had improved. If you have severe difficulty breathing, chest pain, confusion or unusual drowsiness, a fever with a stiff neck or new rash, or your lips turn blue or grey, call 112 immediately.

Frequently asked questions about flu

Can an online doctor prescribe antiviral flu medicine in Europe?

Yes, where clinically appropriate, typically for higher-risk patients seen within the first 48 hours of symptoms. Availability and prescribing rules for flu antivirals vary between EU countries, and the doctor will be straightforward about what is possible where you live.

How quickly can I see a doctor if I think I have flu?

Usually the same day. Appointments run 7 days a week from 7am to 11pm. A video consultation costs €47. The exact price is shown before payment, and there is no subscription. Being seen quickly matters with flu, because antiviral treatment is most useful early.

How do I look after someone with flu at home?

Keep them resting and drinking, control the fever with paracetamol or ibuprofen, ventilate the room, and keep vulnerable household members at a distance in the first days. Watch for the escalation signs, breathlessness, confusion, chest pain, passing very little urine, or getting worse after improving, which need urgent care rather than more waiting.

How do I know if I have flu or just a cold?

Speed and severity. Flu hits within hours with fever, body aches and exhaustion that stops you working; a cold builds over days, stays mostly in the nose and throat, and leaves you functional. If you cannot get out of bed, treat it as flu.

Do antibiotics help flu?

No. Flu is caused by a virus, and antibiotics only work against bacteria; they are prescribed only if a bacterial complication such as pneumonia develops. Taking them without those signs adds side effects and drives antibiotic resistance.

Is it flu or COVID-19?

The symptoms overlap too much to tell reliably; both can bring fever, cough, aches and exhaustion. A rapid test from a pharmacy is the only dependable way to know, and it is worth doing: the result changes isolation advice and, for people in risk groups, treatment options. Mention any positive result to the doctor.

When am I no longer contagious with flu?

With flu, you are much less contagious once your fever has been gone for a full day and you are clearly improving. You are most infectious in the first three to five days of illness, and staying home while feverish protects the people around you; a lingering dry cough on its own does not mean you are still spreading flu.

Should I get the flu vaccine every year?

If you are in a risk group, pregnant, over 65 or living with a chronic condition, or you are a health worker, yes: annual vaccination is the most effective protection, and the vaccine is updated each season, so last year’s dose does not cover this winter. In many EU countries a pharmacy can do it, and autumn is the usual time.
