Runny Nose, Fever, Cough: A Simple Decision Map for What to Use and When

It's Monday morning. You wake up with a headache, a blocked nose, a scratchy throat, and the thermometer shows 37.8°C. You think: "Great, a cold." You go to the pharmacy and look at the shelf - dozens of colourful packages promising relief. But which one to choose?

I know how that feels. The decision can be overwhelming, especially when you're feeling rough. That's why I've prepared a simple decision map for you - a practical guide that will help you choose the right medication depending on exactly what's bothering you. No medical jargon, no complications. Simply: what you have, what to take, done.

First: is it a cold or the flu?

Before you reach for medications, it's worth thinking for a moment about what you're dealing with. This will help you plan treatment better.

A cold - slow start

Symptoms develop gradually over 1-3 days:

• Scratchy throat (often the first symptom)
• Runny nose - watery at first, then thickens
• Cough - usually appears later
• Mild weakness
• Rarely fever (if so, low, up to 38°C)

Flu - hits like a hammer

Symptoms appear suddenly and are intense:

• High fever (38.5-40°C) - often the first symptom
• Severe muscle and joint pain
• Feeling of being shattered, exhaustion
• Headache
• Dry, troublesome cough
• Runny nose may appear but isn't the main symptom

Practical difference: If a cold lets you function (though uncomfortably), the flu knocks you off your feet. With flu you literally can't get out of bed.

Good news? Regardless of whether it's a cold or flu, in most cases you can treat yourself at home. The decision map below will help you choose the right medication for each symptom.

Decision map #1: what to do about a runny nose?

A runny nose is probably the most annoying cold symptom. Your nose runs like a tap, you can't breathe, and tissues become your best friend.

Stage 1: watery runny nose (day one)

Symptoms: Nose runs like a tap, sneezing, watery eyes.

What to use:

• Antihistamines: Cetirizine (e.g. Zyrtec) 10mg once daily or Loratadine (Claritin) 10mg once daily
• How they work: Reduce mucus production, suppress sneezing
• Note: They can cause drowsiness (especially older preparations like Clemastine), so don't drive for the first hour after taking them

Home support:

• Drink plenty of warm fluids (tea, broth)
• Humidify the air in your room (a bowl of water on the radiator works wonders)
• Rinse your nose with saline 3-4 times daily

Stage 2: thick mucus and blocked nose (days 2-5)

Symptoms: Mucus thickens (may be yellowish), nose blocked, hard to breathe, sinus pain.

What to use:

To unblock the nose - drops or sprays

• Oxymetazoline (Afrin, Vicks Sinex) or Xylometazoline (Otrivin, Sudafed)
• How they work: Constrict blood vessels in the nose, instantly clearing it
• Dosage: 2-3 times daily, maximum 5-7 days
• IMPORTANT: Don't use for more than a week! This can lead to dependence and chronic nasal congestion

Safer long-term alternative:

• Saline spray - you can use without limits
• Sea water preparations (Aqualor, Marimer) - moisturise and cleanse
• Hypertonic solutions (stronger salt concentration) - help drain mucus better

To thin the mucus

• Acetylcysteine (ACC/NAC) in effervescent tablets or syrup
• Bromhexine
• Ambroxol (Mucosolvan)
• How they work: Thin thick mucus, making it easier to clear

Practical tip: If you need to function during the day (work, meetings), use drops 15 minutes before leaving home. Save the evening dose so you can sleep peacefully. Between uses, regularly rinse your nose with saline.

What to skip:

• Antibiotics - they don't work on viruses! A cold runny nose is a viral infection. Antibiotics won't help and can be harmful (bacterial resistance, side effects)
• Immune-boosting products with unclear effects - save your money

Decision map #2: how to deal with fever?

Fever is a natural defence mechanism. You don't always need to bring it down immediately. But when it causes discomfort or is high, it's worth helping the body.

When not to bring down a fever?

If the temperature is below 38.5°C and you feel bearable - let the body do its thing. Fever helps fight infection. Drink plenty of fluids, rest, and monitor the temperature.

When to bring down a fever?

Reach for medication when:

• Temperature exceeds 38.5°C
• You feel severe discomfort (muscle aches, chills, feeling awful)
• You have difficulty sleeping
• Fever stays above 38°C for more than 3 days

Which medication to choose?

Option 1: Paracetamol - the safe classic

• Adult dosage: 500-1000mg every 4-6 hours (maximum 4000mg/day, but better not to exceed 3000mg)
• Pros: Gentle on the stomach, safe in pregnancy (after consulting a doctor), works on fever and pain
• Cons: Doesn't work as anti-inflammatory, overdose damages the liver
• When to choose: Good choice if you just have fever and headache without severe muscle pain

Option 2: Ibuprofen - the stronger helper

• Adult dosage: 400mg every 6-8 hours (maximum 1200mg/day without medical consultation)
• Pros: Anti-inflammatory, great for muscle and joint pain (typical of flu), lowers fever
• Cons: Can irritate the stomach (always take with food!), don't use in pregnancy after the second trimester
• When to choose: Ideal for flu - when you have fever + muscle pain + inflammation

My advice: For flu with aching muscles and joints, ibuprofen usually provides better relief than paracetamol. For a regular cold with mild fever, paracetamol is sufficient.

Can you combine them?

Yes, but carefully. If fever is very high and one medication isn't enough, you can alternate:

• 8:00 AM - Paracetamol 500mg
• 12:00 PM - Ibuprofen 400mg
• 4:00 PM - Paracetamol 500mg
• 8:00 PM - Ibuprofen 400mg

But: Use this schedule for a maximum of 1-2 days, and if the fever still won't come down, definitely consult a doctor.

Supportive methods (they really work!)

• Cool compresses on the forehead and wrists (NOT ice-cold - just slightly cool)
• Lukewarm bath (water at about 36°C) - not cold!
• Light clothing - don't wrap up in blankets when you have a fever; the body needs to release heat
• Drink, drink, drink - water, herbal tea, diluted juices; with fever you lose a lot of fluids

Decision map #3: cough - dry or wet?

Cough isn't just one symptom. It's the key to choosing the right medication. First you need to identify what type of cough it is.

Identifying the type of cough

Dry cough (unproductive):

• Scratchy, irritating in the throat
• You don't cough anything up
• Exhausting, often night-time attacks
• Sounds "barking"

Wet cough (productive):

• You feel like there's "something in your chest"
• You cough up phlegm (can be clear, white, yellow)
• Sounds "gurgling"
• After coughing up you feel momentary relief

Treating dry cough

Goal: Suppress the irritating cough, especially at night, so you can rest.

Over-the-counter medications

• Dextromethorphan (various brands)
  • Acts on the cough centre in the brain, suppressing the reflex
  • Dosage: As per the leaflet, usually 15-30mg every 4-8 hours
  • Best at night as it can cause drowsiness
• Butamirate (Sinecod)
  • Similar antitussive effect
  • Available as syrup and drops
  • Good choice for children (from 2 months of age in drops)
• Natural support: Honey-based syrups, marshmallow root extract (soothe the irritated throat)

IMPORTANT: Use cough suppressants only for dry, troublesome cough. Do NOT combine them with expectorants (that would be contradictory action)!

Home remedies

• Honey and lemon - a teaspoon of honey sucked slowly in the mouth has a soothing effect (don't give to children under 1 year!)
• Air humidification - dry air irritates the throat and worsens cough
• Steam inhalation - over a bowl of hot water (carefully to avoid burns), breathe slowly for 10 minutes
• Warm drinks - tea with honey, milk with honey, broths; warmth soothes the irritated throat

Treating wet cough

Goal: Help the body cough up mucus - don't suppress the cough, but support it.

Expectorant (mucolytic) medications

• Acetylcysteine (ACC/NAC)
  • Thins thick mucus
  • Dosage: 600mg once daily or 200mg 3 times daily
  • Available as effervescent tablets, powder, syrup
• Ambroxol (Mucosolvan)
  • Thins mucus and aids its expulsion
  • Dosage: 30mg 3 times daily
• Bromhexine
  • Works similarly to ambroxol (it's its precursor)
• Guaifenesin (in some combination products)
  • Increases the volume of phlegm and makes it easier to cough up

How to use expectorants?

• Take in the morning and during the day (not at night - it may worsen night cough)
• Drink plenty of water - this helps thin the mucus
• After taking them, try to cough up mucus, don't suppress the cough

Home support

• Saline inhalations - moisturise airways and make it easier to cough up
• Postural drainage - after inhalation, lie on your side with your head slightly lowered for a few minutes; helps mucus drain
• Warm drinks - warm and moisturise from the inside
• Proper humidity - 40-60% air humidity in the room is ideal

What if the cough changes from dry to wet?

That's normal! A cold often starts with a dry cough (days 1-3), which then becomes wet (days 4-7) as the body starts producing mucus.

What to do:

1. Days 1-3: Use cough suppressants (at night) and soothing remedies (honey, inhalations)
2. Day 4 onwards: Stop taking cough suppressants, switch to expectorants

When to see a doctor? Warning signs

Most colds you can safely treat at home. But some situations require professional assessment. Don't delay a visit if:

Fever

• Above 39.5°C
• Persists for more than 3 days despite taking medication
• After dropping, returns with greater force

Cough

• Lasts more than 2-3 weeks
• You cough up blood or brown/green phlegm
• You have difficulty breathing, shortness of breath
• You hear wheezing during breathing
• Chest pain during coughing or breathing

General symptoms

• Symptoms worsen instead of improving after 5-7 days
• Severe ear or throat pain (could be a bacterial infection requiring antibiotics)
• Pain or pressure in the sinuses, especially on one side
• Rash appears
• Difficulty swallowing
• Severe headache with stiff neck

High-risk groups

If you belong to any of the following groups, be more vigilant and consult sooner if in doubt:

• People over 65
• Small children (under 2 years)
• Pregnant women
• People with chronic conditions (asthma, COPD, diabetes, heart disease)
• People with weakened immune systems

Saving on cold medications

Now for the practical aspect - treating a cold doesn't have to be expensive. Here are some proven ways to save:

1. Choose single-ingredient medications

"Cold and flu" preparations are often combinations of several substances (paracetamol + pseudoephedrine + caffeine etc.). They're much more expensive and often contain ingredients you don't need.

Instead of buying: Multi-ingredient preparation for €6
Buy separately: Paracetamol for €1.50 + Xylometazoline for €2 = €3.50
Savings: €2.50 (42%)

2. Reach for generics

A generic is the same medication with the same effectiveness, just without the recognisable brand.

Savings examples:

• Paracetamol (generic) €1.50 vs Panadol €5.50 = savings €4 (73%)
• Ibuprofen (generic) €2 vs Nurofen €6 = savings €4 (67%)
• Xylometazoline (generic) €1.75 vs Otrivin €3.75 = savings €2 (53%)

3. Compare prices between pharmacies

The same medication can cost different amounts at different pharmacies - differences reach up to 50%!

Use the CheaperForDrug platform to compare prices across over 100 online pharmacies. Simply add your medications to the virtual basket and the system will show you where to buy them cheapest. You can save tens of euros on a single order.

4. Buy larger packs

If you know the whole family uses a given medication (e.g. paracetamol), a pack of 50 tablets is proportionally cheaper than 20 tablets.

Example:
Paracetamol 20 tablets = €1.50 (€0.075/tablet)
Paracetamol 50 tablets = €2.75 (€0.055/tablet)
Savings: 27% per tablet

5. Watch out for free delivery

Some pharmacies offer free delivery above a certain amount (e.g. €25). If you're planning to buy several products anyway, it's worth combining them in one order and saving on shipping.

Home cold medicine cabinet - what's worth having?

To avoid panic when a cold strikes, prepare a basic medicine cabinet in advance:

Must-have (absolute basics)

• Paracetamol 500mg, 50 tablets (~€2.50)
• Ibuprofen 400mg, 20 tablets (~€2)
• Saline spray (~€3)
• Nasal drops with xylometazoline (~€2)
• Thermometer (if you don't have one yet)

Basic kit cost: ~€10

Nice-to-have (extended)

• NAC/ACC 600mg effervescent tablets (~€4.50)
• Cough syrup (Sinecod or similar, ~€5.50)
• Throat lozenges (~€3.75)
• Vitamin C 1000mg (~€3.75)

Extended kit cost: ~€18

For less than €25 you have a complete medicine cabinet that will last through several cold episodes for the whole family. And remember: by buying smartly through CheaperForDrug, you can pay even less!

Cold treatment myths

Myth 1: "Vitamin C prevents colds"

Truth: Regular vitamin C intake may slightly shorten the duration of a cold (by about half a day), but it doesn't prevent infection. Exception: athletes and people exposed to extreme cold may benefit more.

Myth 2: "Antibiotics will speed up recovery"

Truth: Colds and flu are viral infections. Antibiotics work ONLY on bacteria. Taking antibiotics for viruses won't help and can be harmful (bacterial resistance, side effects).

Myth 3: "You need to sweat it out and the fever will drop faster"

Truth: Wrapping up in blankets and "sweating out" a fever is a myth. The body needs to release heat for the temperature to drop. Dress lightly and use cool compresses.

Myth 4: "Green nasal discharge = antibiotics"

Truth: The colour of discharge (yellow, green) alone does NOT indicate a bacterial infection. It's a natural process as the body fights a virus. Antibiotics are only needed if symptoms worsen after 7-10 days or are very severe.

Myth 5: "The more medications, the faster the recovery"

Truth: More does not equal better. Too many medications at once increase the risk of side effects and interactions. Choose a few targeted preparations for specific symptoms, don't take everything at once.

Prevention - how not to catch a cold

The best strategy is not to get sick at all. Here are proven ways to reduce the risk:

Hygiene basics

• Wash your hands frequently - especially after returning home, before eating, after contact with sick people
• Don't touch your face - viruses enter the body through eyes, nose, and mouth
• Disinfect frequently used items - phone, keyboard, door handles

Boosting immunity

• Get enough sleep - 7-9 hours of sleep is a key immunity factor
• Eat healthily - plenty of vegetables, fruit, protein; avoid excess sugar
• Exercise - regular, moderate physical activity supports the immune system
• Manage stress - chronic stress weakens immunity
• Don't smoke - smoking weakens airway defence mechanisms

During cold season

• Humidify the air - heating dries out mucous membranes, which are the first line of defence
• Avoid crowds - if you can, especially in enclosed spaces
• Dress appropriately - getting cold weakens local immunity
• Ventilate rooms - fresh air = fewer viruses in the air

Summary - your cheat sheet

Here's your quick guide that you can save or print:

For a runny nose:

• Watery (day 1): Cetirizine/Loratadine + saline rinse
• Blocked (days 2-5): Oxymetazoline drops (max 7 days) + ACC/Ambroxol + saline rinse

For fever:

• Below 38.5°C and feeling bearable: Monitor, drink plenty, rest
• Above 38.5°C or severe discomfort: Paracetamol 500-1000mg or Ibuprofen 400mg
• Flu with muscle pain: Ibuprofen works better

For cough:

• Dry, troublesome: Dextromethorphan/Sinecod at night + honey + inhalation
• Wet with mucus: ACC/Ambroxol during the day + plenty of water + inhalation
• Do NOT combine: cough suppressants with expectorants!

See a doctor if:

• Fever >39.5°C or >3 days
• Cough >2-3 weeks or with blood
• Difficulty breathing
• Symptoms worsen instead of improving

Save smartly:

• Choose single-ingredient medications instead of combination products
• Buy generics (50-70% cheaper, equally effective)
• Compare prices on CheaperForDrug - save up to 50%
• Build a home medicine cabinet in advance (~€10-25)

A cold is annoying but in most cases harmless. With the right knowledge and the right medications you'll get through it faster and more comfortably. And with smart purchasing you'll save a good amount of money that you can spend on something more pleasant than medication - for example, on strengthening your body after illness!

Remember: it's just a cold. In a few days you'll feel better. And in the meantime - rest, drink plenty of fluids, and be kind to yourself. Your body is fighting the virus and doing a pretty good job of it.
