Lemsip Max Cold & Flu - 16 Capsules

What Are Lemsip Max Cold and Flu Capsules?

Lemsip Max Cold and Flu capsules are an over-the-counter combination medicine designed to tackle the most disruptive symptoms of colds and flu in one go. Each pack contains 16 capsules, making it a practical option to keep at home or in your bag when symptoms strike. Cold and flu are among the most common reasons people visit a pharmacist in the UK, and having a reliable remedy to hand can make a real difference to how quickly you get back on your feet. You can explore our full range of cold and flu treatments if you need additional support alongside these capsules.

Each capsule contains two active ingredients: paracetamol 500mg and phenylephrine hydrochloride 6.1mg. Paracetamol is one of the most widely used analgesics and antipyretics in the UK, recommended by the NHS for relieving mild to moderate pain and reducing fever. Phenylephrine is a sympathomimetic decongestant that helps clear a blocked nose. Together, they address several symptoms at once — which is exactly what you need when a cold or flu hits hard.

How Do Lemsip Max Cold and Flu Capsules Work?

Understanding how a medicine works helps you use it more confidently. These capsules act through two distinct mechanisms:

• Paracetamol inhibits the production of prostaglandins in the brain and spinal cord, reducing the perception of pain and lowering an elevated body temperature (fever). It is effective for headache, sore throat pain, and the general aching that often accompanies flu.
• Phenylephrine hydrochloride acts as an alpha-adrenergic agonist, causing vasoconstriction (narrowing of blood vessels) in the nasal mucosa. This reduces swelling and congestion in the nasal passages, making it easier to breathe.
• The combination means you are addressing fever, pain, and congestion simultaneously rather than needing separate products.
• Onset of action for paracetamol is typically within 30 to 60 minutes of taking a dose orally.

Who Should Use Lemsip Max Cold and Flu Capsules?

These capsules are suitable for adults and young people aged 12 and over who are experiencing symptoms of a cold or flu. They are particularly useful if you are dealing with more than one symptom at the same time — for instance, a blocked nose alongside a headache and fever. That said, they are not appropriate for everyone, so it is worth checking the list below before you start.

This product is well suited to:

• Adults and adolescents aged 12 years and over
• People experiencing nasal congestion, headache, sore throat, or fever caused by a cold or flu
• Those who prefer a capsule format over hot drinks or liquid medicines
• People who need symptom relief during the day or night (though note the phenylephrine may affect sleep in some individuals)

What Is Lemsip Max Cold & Flu and What Is It Used For?

Lemsip Max Cold & Flu 16 Capsules is an over-the-counter combination medicine used to relieve the symptoms of colds and influenza (flu) in adults and young people aged 12 and over. It contains paracetamol, which reduces fever and relieves pain such as headache and sore throat, alongside phenylephrine hydrochloride, a nasal decongestant that helps unblock a stuffy nose. The NHS advises that most colds and flu episodes can be managed at home with rest, fluids, and appropriate over-the-counter medicines — and this product is designed to support exactly that approach.

What Do You Need to Know Before Using Lemsip Max Cold & Flu?

Before taking these capsules, it is important to check whether they are appropriate for you. Do not take this medicine if any of the following apply:

• You are under 12 years of age
• You are allergic to paracetamol, phenylephrine, or any other ingredient in the capsule
• You have severe liver disease or severe kidney disease
• You have uncontrolled high blood pressure (hypertension)
• You have a condition called phaeochromocytoma (a rare adrenal gland tumour)
• You are currently taking or have taken monoamine oxidase inhibitors (MAOIs) within the last 14 days
• You are already taking another medicine containing paracetamol — this is a particularly important point, as exceeding the safe paracetamol dose can cause serious liver damage

You should also be aware of the following potential drug interactions:

• Other sympathomimetic medicines (e.g. some nasal decongestant sprays or appetite suppressants)
• Tricyclic antidepressants — may enhance the cardiovascular effects of phenylephrine
• Warfarin and other anticoagulants — regular use of paracetamol may increase anticoagulant effect
• Metoclopramide or domperidone — may increase the rate of paracetamol absorption
• Cholestyramine — may reduce paracetamol absorption if taken at the same time

If you are pregnant or breastfeeding, speak to your pharmacist or GP before taking this product. Phenylephrine is generally not recommended during pregnancy.

How Should You Use Lemsip Max Cold & Flu?
