What is Lemsip Max All in One Liquid?

Lemsip Max All in One liquid is a medicine that can help to tackle lots of your cold and flu symptoms all at once. Take this medicine four times a day to ease coughs, headaches, a runny nose, a sore throat, and more! If you’re looking for a way to ease your cold when you’re suffering with lots of different symptoms, Lemsip Max All in One liquid could be the perfect remedy for you.


What symptoms will I get if I have a cold?

If you have a cold, there’s a whole list of symptoms that you may experience. You may have one or two, or even the whole lot at once, but these symptoms all come together to make getting a cold feel miserable. Some of the most common cold symptoms include:

  • Cough
  • Sneezing
  • Blocked or runny nose
  • Sore throat
  • Headache
  • Pressure in the head and face
  • Muscle aches and pains
  • Feeling tired or fatigued


How will Lemsip Max All in One Liquid treat my cold or flu?

Lemsip Max All in One liquid contains four active ingredients which all work together to ease your cold and flu symptoms. These ingredients are:

  • Paracetamol
  • Phenylephrine
  • Guaifenesin
  • Cetylpyridinium chloride

Paracetamol is a popular painkiller, and it helps to ease headaches, sore throats, and other aches and pains, as well as bringing down a high temperature. Phenylephrine is a decongestant, and it reduces the swelling in your nasal passages, relieving a blocked nose and easing pressure build up in your head and face. Guaifenesin is an expectorant, which means it loosens phlegm, making it easier to cough up. This eases your chesty cough and makes it easier to breathe. Finally, cetylpyridinium chloride is an antiseptic and anti-infective, which means it helps to ease sore throats and prevent infection in the area.
