The Story
What Is Lemsip Max Cold and Flu Lemon?
Lemsip Max Cold and Flu Lemon is a well-known over-the-counter hot drink sachet designed to tackle the full range of cold and flu symptoms in one go. Each sachet contains two active ingredients — paracetamol 1000 mg and phenylephrine hydrochloride 12.2 mg — working together to relieve sore throat pain, headache, aching limbs, blocked nose, and fever. If you've ever felt completely floored by a winter cold, you'll know how much it helps to have something that addresses several symptoms at once rather than reaching for multiple different products. You can find it alongside other cold and flu remedies in our cold and flu collection.
The lemon flavour makes it genuinely pleasant to drink — which matters when you're feeling rough and the last thing you want is something unpleasant. It's a P (pharmacy) medicine, meaning it's available without a prescription but should be used according to the label instructions.
How Does Lemsip Max Cold and Flu Lemon Work?
The two active ingredients each play a distinct role in relieving your symptoms. Here's how they work:
- Paracetamol (1000 mg): Acts as both an analgesic (pain reliever) and an antipyretic (fever reducer). It works centrally in the brain to raise the pain threshold and lower elevated body temperature, helping with sore throat discomfort, headaches, and muscle aches.
- Phenylephrine hydrochloride (12.2 mg): A sympathomimetic decongestant. It causes vasoconstriction — narrowing of the blood vessels — in the nasal mucosa, which reduces swelling and congestion so you can breathe more easily.
- Hot water: The warm liquid itself can soothe an irritated throat and help loosen mucus, adding a simple but meaningful physical benefit on top of the pharmacological action.
Together, these mechanisms mean you're addressing pain, fever, and congestion simultaneously — rather than treating each symptom separately.
Who Should Use Lemsip Max Cold and Flu Lemon?
This product is intended for adults and young people aged 16 and over who are experiencing cold or flu symptoms. It's particularly useful if you have a combination of symptoms — for example, a blocked nose alongside a sore throat and headache — and want a single, convenient treatment. That said, it isn't right for everyone.
Lemsip Max Cold and Flu Lemon is suitable for:
- Adults aged 16 and over with cold or flu symptoms
- People experiencing sore throat, headache, or muscle aches alongside nasal congestion
- Those who prefer a hot drink format over tablets or capsules
- Individuals who need paracetamol-based relief but also require a decongestant
It is not suitable for children under 12, and those aged 12–15 should only use it under adult supervision. Always check the label carefully.
How Does Lemsip Max Compare to Standard Lemsip?
| Feature | Lemsip Max Cold & Flu Lemon | Lemsip Original Lemon |
|---|---|---|
| Paracetamol dose | 1000 mg per sachet | 650 mg per sachet |
| Decongestant | Phenylephrine 12.2 mg | Phenylephrine 6.1 mg |
| Suitable age | 16 and over | 12 and over |
| Symptom focus | Multi-symptom (max strength) | Multi-symptom (standard strength) |
Is Lemsip Max Cold and Flu Lemon Safe to Store at Home?
Yes — storing Lemsip Max Cold and Flu Lemon correctly is straightforward. Keep the sachets below 25°C in a dry place, away from direct sunlight and out of reach of children. Do not use any sachet past its printed expiry date, and always check the packaging is intact before use. If you're managing multiple symptoms and also need support for throat discomfort, our ear, nose and throat collection has a range of complementary products worth exploring.
This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Lemsip Max Cold & Flu Lemon - 10 Sachets
What Is Lemsip Max Cold & Flu Lemon and What Is It Used For?
Lemsip Max Cold & Flu Lemon is an over-the-counter medicine used to relieve the symptoms of colds and flu in adults and young people aged 16 and over. Each sachet contains paracetamol 1000 mg to reduce pain and fever, and phenylephrine hydrochloride 12.2 mg to relieve nasal congestion. It's indicated for sore throat, headache, aching muscles, blocked or runny nose, and raised temperature — essentially the cluster of symptoms that make a cold or flu feel so draining. The NHS advises that most colds clear up on their own within 7 to 10 days, but symptomatic relief can make that time considerably more manageable.
What Do You Need to Know Before Using Lemsip Max Cold & Flu Lemon?
Before taking this medicine, read the following carefully. There are situations where it should not be used, and others where caution is needed.
Do not take Lemsip Max Cold & Flu Lemon if you:
- Are allergic to paracetamol, phenylephrine, or any other ingredient in the sachet
- Are taking monoamine oxidase inhibitors (MAOIs) or have taken them within the last 14 days
- Have severe liver disease or severe kidney impairment
- Have uncontrolled high blood pressure (hypertension)
- Are under 12 years of age
- Are already taking other products containing paracetamol
Use with caution and speak to a pharmacist or doctor if you:
- Have heart disease, diabetes, or an overactive thyroid (hyperthyroidism)
- Have liver or kidney problems (even mild)
- Are pregnant or breastfeeding
- Are taking tricyclic antidepressants, beta-blockers, or other sympathomimetics
- Are aged 12–15 (use only under adult supervision)
Known drug interactions include:
- MAOIs — risk of hypertensive crisis
- Other paracetamol-containing medicines — risk of paracetamol overdose
- Tricyclic antidepressants — may enhance the pressor effect of phenylephrine
- Beta-blockers — may interact with phenylephrine's vasoconstrictive action
- Warfarin — regular paracetamol use may enhance anticoagulant effect
How Should You Use Lemsip Max Cold & Flu Lemon?
Always use this medicine exactly as described on the label. If you're unsure, ask your pharmacist. Here's how to prepare and take each dose:
- Empty the contents of one sachet into a large mug.
- Add freshly boiled water — approximately 200–250 ml.
- Stir thoroughly until the powder is fully dissolved.
- Allow the drink to cool to a comfortable temperature before sipping.
- Take one sachet every four to six hours as needed.
- Do not take more than four sachets in any 24-hour period.
| Indication | Age Group | Dose | Frequency |
|---|---|---|---|
| Cold & flu symptoms | Adults & young people 16+ | 1 sachet | Every 4–6 hours (max 4 in 24 hrs) |
| Cold & flu symptoms | 12–15 years (adult supervision) | Not recommended — use standard Lemsip | — |
| Children under 12 | Under 12 | Not suitable | — |
If your symptoms persist beyond five days, or if your fever lasts more than three days, stop use and consult a doctor. You might also find it helpful to browse our pain relief collection for additional options to manage aches and discomfort alongside your cold treatment.
What Are the Possible Side Effects of Lemsip Max Cold & Flu Lemon?
Like all medicines, Lemsip Max Cold & Flu Lemon can cause side effects, although not everyone experiences them. The NHS notes that paracetamol is generally well tolerated at recommended doses, but phenylephrine can occasionally cause cardiovascular effects.
Common side effects:
- Nausea or stomach upset
- Difficulty sleeping (insomnia)
- Mild increase in heart rate
- Headache (if taken in excess)
Less common side effects:
- Raised blood pressure
- Palpitations

Frequently Asked Questions
Where can I buy Lemsip Max Cold and Flu Lemon online in the UK?
You can buy Lemsip Max Cold and Flu Lemon 10 sachets directly from Cured Pharmacy, a GPhC-registered online pharmacy offering fast UK delivery. It's available without a prescription as a Pharmacy (P) medicine. Browse our full cold and flu collection for related products too.
How does Lemsip Max Cold and Flu Lemon work in the body?
Lemsip Max Cold and Flu Lemon contains paracetamol, which reduces pain and fever by acting on the central nervous system, and phenylephrine hydrochloride, a decongestant that narrows blood vessels in the nasal lining to ease congestion. The warm liquid also helps soothe an irritated throat and loosen mucus. Together, these actions target the most disruptive cold and flu symptoms at once.
How do I prepare and take Lemsip Max Cold and Flu Lemon correctly?
Empty one sachet into a mug, pour in freshly boiled water, and stir until the powder is fully dissolved. Let it cool slightly before drinking — it should be warm, not scalding. Take one sachet every four to six hours, and never exceed four sachets in a 24-hour period.
What is the correct dose of Lemsip Max Cold and Flu Lemon for adults?
Adults and young people aged 16 and over should take one sachet dissolved in hot water every four to six hours as needed. The maximum dose is four sachets in any 24-hour period. Do not take a higher dose thinking it will work faster — it won't, and it increases the risk of side effects.
Can I take Lemsip Max Cold and Flu Lemon with paracetamol tablets?
No — you must not take Lemsip Max alongside any other paracetamol-containing product, including standard paracetamol tablets, other cold and flu remedies, or combination painkillers. Each sachet already contains the maximum single adult dose of paracetamol (1000 mg), and exceeding the daily limit can cause serious liver damage. Always check the ingredients of any other medicine you're taking.
Who should not take Lemsip Max Cold and Flu Lemon?
This product is not suitable for children under 12, people with severe liver or kidney disease, those with uncontrolled high blood pressure, or anyone currently taking or who has recently taken MAOIs. Pregnant or breastfeeding women should speak to a doctor or pharmacist before use. If you have heart disease, diabetes, or thyroid problems, seek advice before taking it.
Is Lemsip Max Cold and Flu Lemon safe during pregnancy?
The NHS advises that paracetamol is generally considered the first-choice painkiller during pregnancy when used at the lowest effective dose for the shortest time. However, phenylephrine — the decongestant in Lemsip Max — is not recommended during pregnancy, particularly in the first trimester. You should speak to your midwife, GP, or pharmacist before taking this product if you are pregnant.
What are the side effects of Lemsip Max Cold and Flu Lemon?
Common side effects include nausea, difficulty sleeping, and a mild increase in heart rate. Less commonly, you may experience raised blood pressure, palpitations, dizziness, or a skin rash. Serious allergic reactions are rare but require immediate medical attention — stop taking the medicine and call 999 if you develop swelling of the face or throat or difficulty breathing.
How do I manage side effects of Lemsip Max Cold and Flu Lemon?
If you experience nausea, try taking the sachet with a small amount of food or a light snack beforehand. For sleep disturbance, avoid taking a dose close to bedtime if possible. If side effects feel significant or persistent, stop use and speak to your pharmacist — they can suggest an alternative from our ear, nose and throat range.
How long can I use Lemsip Max Cold and Flu Lemon for?
Do not use Lemsip Max for more than five days for pain relief, or more than three days if you're using it primarily to reduce a fever, without consulting a doctor or pharmacist. If your symptoms haven't improved within this time, or if they worsen, you should seek medical advice. Prolonged use without supervision is not recommended.
What is the best time to take Lemsip Max Cold and Flu Lemon?
There's no single "best" time — take it when your symptoms are most troublesome, spacing doses at least four hours apart. Many people find it helpful first thing in the morning when congestion and aching tend to feel worst, and again in the afternoon. Avoid taking a dose containing phenylephrine immediately before bed if you're sensitive to stimulants, as it may affect sleep.
What happens if I miss a dose of Lemsip Max Cold and Flu Lemon?
Simply take the next sachet when you need it, ensuring at least four hours have passed since your last dose. Do not double up or take two sachets close together to make up for a missed one. This medicine is taken as needed for symptom relief, not on a strict schedule, so missing a dose is not a clinical concern as long as you stay within the daily maximum.
What are the alternatives to Lemsip Max Cold and Flu Lemon?
Alternatives include standard-strength Lemsip Original (lower paracetamol and phenylephrine doses, suitable from age 12), Beechams All-In-One, or Day Nurse capsules — all of which contain similar active ingredients in varying strengths. If you only need pain and fever relief without a decongestant, plain paracetamol tablets are a simpler option available in our pain relief collection. Your pharmacist can help you choose the most appropriate product for your specific symptoms.
Can I drink alcohol while taking Lemsip Max Cold and Flu Lemon?
You should avoid alcohol while taking this product. Alcohol combined with paracetamol increases the risk of liver damage, and it can also worsen dehydration — which is already a concern when you have a fever or cold. The NHS recommends staying well hydrated with water and warm drinks when you have a cold or flu, so alcohol is best avoided entirely during this time.
What does the latest guidance say about treating cold and flu symptoms at home?
The NHS recommends rest, staying hydrated, and using over-the-counter medicines like paracetamol or ibuprofen to manage symptoms of cold and flu at home. Decongestants such as phenylephrine can help with nasal congestion but should not be used for extended periods. Antibiotics are not effective against viral infections like colds or flu, so symptomatic relief with products like Lemsip Max Cold and Flu Lemon remains the standard approach for otherwise healthy adults.
