What is the difference between the common cold and the flu?

Initially, it can be difficult to tell the difference between cold and flu as they share a lot of similar symptoms. The main difference between a cold and the flu is how severe the symptoms are. Flu symptoms tend to be more severe than a cold, so you may feel more tired or unable to go to work if you have the flu. Another key difference between a cold and the flu is a fever. Although your temperature may rise a little if you have a cold, the flu can cause a higher fever that can last for 3 - 4 days before easing. 

What are the main symptoms of a cold?

  • A blocked or runny nose
  • A sore throat
  • Headaches
  • Coughs 
  • Sneezing
  • A raised temperature
  • Pressure in your ears and face 
  • Loss of taste and smell

What are the symptoms of the flu?

Symptoms of the flu include most if not all the symptoms of a cold, as well as:

  • A sudden fever - a temperature of 38°C or above
  • Aching
  • Feeling tired 
  • Difficulty sleeping
  • Loss of appetite
  • Diarrhoea or tummy pain 
  • Feeling sick and being sick

How to treat symptoms of cold and flu

The best remedy for a cold or the flu is to rest, keep yourself warm and drink plenty of water to avoid dehydration. Take paracetamol or ibuprofen to lower a high temperature and relieve aches if necessary. The common cold and the flu are viral infections which means they are caused by viruses. Antibiotics are for bacterial infections therefore will have no effect on viruses and can encourage resistance making them less effective. Antibiotics may only be prescribed if you develop a complication as a result of flu, such as a bacterial chest infection. 

How can Lemsip Capsules help to relieve cold and flu symptoms?

Lemsip Max contain two active ingredients that help to deal with heavy cold and flu symptoms:

  • Paracetamol
  • Phenylephrine hydrochloride 

Paracetamol is a pain killer (also known as an analgesic). It provides effective relief from aches, pains, headaches and can reduce fever. Phenylephrine hydrochloride is a decongestant which works by reducing swelling in the passages of the nose to relieve nasal congestion and reduce the pressure that can cause a headache during a cold or the flu. Lemsip Max Capsules also contain caffeine which is a mild stimulant that helps to relieve fatigue and drowsiness through the day as well as speeding up the effect of the paracetamol, to relieve symptoms quicker than paracetamol alone.

How to use this product

These capsules are only suitable for adults, the elderly and children aged 16 and over. Swallow the capsules whole with water - do not chew. 

Dosage: take 2 capsules every 4-6 hours as required to a maximum of 4 doses in 24 hours or up to a maximum of 3 doses in any 24 hours if a night-time paracetamol-containing product is taken before bedtime. Do NOT take more than 8 capsules (4 doses) in any 24 hours. 


Do NOT give to children under 16 years of age. If the symptoms of your cold or flu persist for more than three days or worsen, consult your doctor or a Chemist4U pharmacist. If you take more capsules than you should speak to your doctor at once, even if you feel well. Paracetamol can cause delayed, serious liver damage. You may experience:
