What Is Calpol Infant Sugar Free Suspension?

 

When your baby is unwell — running a temperature, cutting their first teeth, or just clearly uncomfortable — you want something that works and that you can trust. Calpol infant sugar free suspension has been a go-to choice for parents across the UK for decades, and for good reason. This 100ml strawberry-flavoured liquid contains paracetamol 120mg per 5ml and is specifically formulated for babies and young children from 2 months of age. It's free from sugar, artificial colours, and gluten, which makes it a thoughtful option for families who want to avoid unnecessary additives in their little one's medicine. You'll find it and other trusted remedies in our baby and toddler collection.

Paracetamol is one of the most widely used and well-studied medicines in the world. The NHS recommends it as a first-line treatment for mild to moderate pain and fever in children, and this suspension delivers it in a form that's easy to measure and gentle to give. At just £3.89 for 100ml, it's an accessible option for every household with young children.

 

How Does Calpol Infant Sugar Free Suspension Work?

 

Paracetamol — the active ingredient in this suspension — works primarily in the central nervous system. It reduces fever by acting on the hypothalamus, the part of the brain that regulates body temperature, and it relieves pain by inhibiting the synthesis of prostaglandins, the chemical messengers that signal pain and inflammation. Here's a simple breakdown of the mechanism:

  • Paracetamol is absorbed through the gut lining after swallowing
  • It travels via the bloodstream to the brain and central nervous system
  • It blocks prostaglandin production, reducing the sensation of pain
  • It acts on the hypothalamus to lower an elevated body temperature
  • Effects typically begin within 30–60 minutes of administration

Unlike ibuprofen, paracetamol does not have significant anti-inflammatory properties, but it is gentler on the stomach and suitable from a younger age. This makes it the preferred first choice for very young babies.

 

Who Should Use Calpol Infant Sugar Free Suspension?

 

This suspension is designed for babies and young children who need relief from mild to moderate pain or a high temperature. It's particularly useful in the following situations:

  • Babies aged 2 months and over with a fever (temperature of 38°C or above)
  • Infants experiencing discomfort after routine vaccinations
  • Young children with teething pain or earache
  • Children with a cold, sore throat, or headache

It is not suitable for babies under 2 months of age. If your baby was born prematurely or has an underlying health condition such as liver or kidney problems, speak to your GP or pharmacist before use.

Is Calpol Infant Sugar Free Suspension Safe to Store at Home?

Do not refrigerate the suspension, as this can affect the consistency of the liquid. Once opened, use within 3 months. If you're building a home medicine cabinet, you might also want to explore our pain relief range for other trusted options.

What Is Calpol Infant Sugar Free Suspension and What Is It Used For?

 

Calpol Infant Sugar Free Strawberry Suspension is an oral paracetamol liquid medicine containing 120mg of paracetamol per 5ml. It is used to relieve mild to moderate pain and to reduce fever (high temperature) in babies and young children from 2 months of age. Common reasons parents reach for this suspension include teething discomfort, earache, sore throat, headache, and fever following routine childhood vaccinations. The NHS recommends paracetamol as a safe and effective first-line option for managing pain and fever in children when used at the correct dose.

This formulation is free from sugar, artificial colours, and gluten. The strawberry flavour makes it more palatable for young children, and the colour-free formula is a reassurance for parents who prefer to minimise additives. It is a General Sale List (GSL) medicine, meaning it can be purchased without a prescription.

 

What Do You Need to Know Before Using Calpol Infant Sugar Free Suspension?

 

Before giving this medicine to your child, read the following carefully. There are situations where it should not be used, and others where extra caution is needed.

Do not use this suspension if your child:

  • Is under 2 months of age
  • Has a known allergy to paracetamol or any other ingredient in the product
  • Has severe liver or kidney disease
  • Is already taking another medicine containing paracetamol

Use with caution and speak to a pharmacist or GP if your child:

  • Was born prematurely
  • Has liver or kidney problems
  • Is malnourished or has a low body weight
  • Is taking any other regular medicines

Known drug interactions to be aware of:

  • Warfarin — regular use of paracetamol may enhance the anticoagulant effect
  • Other paracetamol-containing products — concurrent use risks overdose
  • Metoclopramide or domperidone — may increase the rate of paracetamol absorption
  • Cholestyramine — may reduce paracetamol absorption if taken within one hour

 

How Should You Use Calpol Infant Sugar Free Suspension?

 

Always use the oral dosing syringe included in the pack — never use a kitchen spoon, as this can lead to inaccurate dosing. Shake the bottle well before each use. Here's how to give the suspension safely:

  1. Check your child's age and weight to confirm the correct dose
  2. Shake the bottle gently before opening
  3. Draw up the correct dose using the oral syringe provided
  4. Place the syringe gently into the side of your baby's mouth
  5. Slowly push the plunger to release the medicine — do not rush
  6. Rinse the syringe with clean water after each use
Age Dose Maximum doses per 24 hours
2–3 months (post-vaccination fever only) 2.5ml (one dose only) 1
3–6 months 2.5ml 4
6–24 months 5ml 4
2–6 years 5–10ml 4

Leave at least 4 hours between each dose. Do not give more than 4 doses in any 24-hour period. If your child's symptoms do not improve within 24 hours (for fever) or 48 hours (for pain), seek medical advice. For broader children's health support, our cold and flu collection includes additional remedies suitable for older children.

 

What Are the Possible Side Effects of Calpol Infant Sugar Free Suspension?

 

Paracetamol is generally very well tolerated in children when used at the correct dose. Serious side effects are rare. However, as with any medicine, reactions can occur. If your child shows signs of an allergic reaction — such as swelling of the face, lips, or throat, difficulty breathing, or a widespread rash — stop the medicine immediately and call 999 or go to your nearest A&E.

Common side effects (may affect up to 1 in 10 children):

  • Skin rash or itching
  • Mild stomach upset

Less common or rare side effects:

  • Allergic reactions including urticaria (hives)
  • Low blood pressure (hypotension) — very rare, associated with intravenous use, not oral
  • Blood disorders such as thrombocytopenia — extremely rare with oral use at recommended doses
  • Liver damage — only a risk in cases of overdose; never exceed the recommended dose

 

How Should You Store Calpol Infant Sugar Free Suspension?

 

Correct storage keeps the medicine safe and effective for the full duration of use. Follow these guidelines:

  • Store below 25°C in a cool, dry place
  • Do not refrigerate — cold temperatures can affect the suspension
  • Keep the bottle tightly closed when not in use
  • Keep out of the sight and reach of children at all times
  • Do not use after the expiry date printed on the label
  • Once opened, use within 3 months
  • Do not dispose of medicines via wastewater or household waste — return unused medicine to your pharmacy

How does Calpol Infant Sugar Free Suspension work in the body?

This suspension contains paracetamol 120mg per 5ml, which works by inhibiting prostaglandin synthesis in the brain and central nervous system, reducing the perception of pain and lowering an elevated body temperature. It acts on the hypothalamus — the brain's temperature control centre — to bring a fever down. Effects typically begin within 30 to 60 minutes of giving the dose.

What age can babies start taking Calpol Infant Sugar Free Suspension?

Calpol Infant Sugar Free Suspension is suitable for babies from 2 months of age. For babies aged 2 to 3 months, it should only be used to treat post-vaccination fever, and only one dose should be given before seeking medical advice if symptoms continue. Never give this medicine to a baby under 2 months old.

How do I give Calpol Infant Suspension to my baby step by step?

Shake the bottle well, then draw up the correct dose using the oral syringe provided — never use a kitchen spoon. Place the syringe gently into the side of your baby's mouth and slowly push the plunger to release the liquid. Rinse the syringe with clean water after every use and store the bottle below 25°C with the cap tightly closed.

What is the correct dose of Calpol Infant Suspension for my child's age?

The dose depends on your child's age: babies aged 3–6 months receive 2.5ml, children aged 6 months to 2 years receive 5ml, and children aged 2–6 years receive 5–10ml. For babies aged 2–3 months, only one dose of 2.5ml is recommended for post-vaccination fever. Always leave at least 4 hours between doses and give no more than 4 doses in 24 hours.

How often can I give Calpol Infant Sugar Free Suspension?

You can give this suspension every 4 to 6 hours as needed, but never more than 4 doses in any 24-hour period. Always wait at least 4 hours between doses, even if your child's symptoms return sooner. If you find yourself needing to give it repeatedly over several days, speak to your GP.

Is Calpol Infant Sugar Free Suspension suitable for babies with allergies or dietary needs?

Yes — this formulation is free from sugar, artificial colours, and gluten, making it a suitable choice for many babies with common dietary sensitivities. However, it does contain other excipients including maltitol liquid and sorbitol, so always check the full ingredients list if your child has specific allergies. When in doubt, ask your pharmacist before use.

What are the side effects of Calpol Infant Sugar Free Suspension?

Side effects are uncommon when the suspension is used at the correct dose. The most likely reactions include skin rash or mild stomach upset. Rarely, an allergic reaction may occur — signs include swelling of the face or throat, difficulty breathing, or hives — in which case you should stop the medicine and seek emergency medical help immediately.

What happens if I accidentally give my child too much Calpol?

Paracetamol overdose is a medical emergency, even if your child seems well initially, because liver damage can develop hours later. If you think your child has taken too much, go to your nearest A&E or call 999 immediately — do not wait for symptoms to appear. Take the medicine bottle with you so doctors can see exactly what was taken.

Can I give Calpol Infant Suspension alongside other medicines?

Do not give this suspension alongside any other product containing paracetamol, including cold and flu remedies, as this significantly increases the risk of overdose. If your child is taking any regular prescribed medicines, check with your pharmacist or GP before giving Calpol. You can explore our cold and flu range for age-appropriate alternatives.

What are the alternatives to Calpol Infant Sugar Free Suspension?

The main alternative analgesic and antipyretic for children is ibuprofen suspension, which is suitable from 3 months of age and has anti-inflammatory properties that paracetamol lacks. However, ibuprofen is not suitable for all children — for example, those with asthma or kidney problems — so always check suitability with a pharmacist. For babies under 3 months, paracetamol suspension is the only recommended option.

How long can I use Calpol Infant Suspension for?

For fever, if your child's temperature has not improved within 24 hours of starting treatment, seek medical advice. For pain, if symptoms persist beyond 48 hours, consult your GP or pharmacist. This medicine is intended for short-term use only — it is not designed for ongoing daily administration without medical supervision.

What should I do if I miss a dose of Calpol Infant Suspension?

If you miss a dose and your child is still in discomfort or has a fever, you can give the next dose as soon as you remember — provided at least 4 hours have passed since the last dose. Never give a double dose to make up for a missed one. If you are unsure, speak to your pharmacist for guidance.

Is Calpol Infant Sugar Free Suspension safe after vaccinations?

Yes — the NHS advises that paracetamol suspension can be used to treat fever and discomfort following routine childhood vaccinations. For babies aged 2–3 months who develop a post-vaccination fever, one dose of 2.5ml is recommended. If the fever does not settle or your baby seems very unwell, contact your GP or call NHS 111.

What is the latest guidance on using paracetamol for children's fever?

Current NHS guidance recommends paracetamol as a safe and effective first-line treatment for fever and mild to moderate pain in children, used at the lowest effective dose for the shortest time necessary. Routine use of paracetamol to prevent post-vaccination fever is no longer recommended — it should only be given if a fever actually develops. Always follow the dosing instructions on the pack and seek medical advice if you are concerned about your child's condition.

How Should You Use Calpol Infant Sugar Free Suspension?

Always use the oral dosing syringe included in the pack — never a kitchen spoon, as this makes accurate measurement impossible. Shake the bottle well before every use to ensure the suspension is evenly mixed. Give the medicine by placing the syringe gently into the side of your baby's mouth and releasing the liquid slowly so they can swallow comfortably.

Follow these steps each time you give a dose:

What Is the Correct Dose of Calpol Infant Sugar Free Suspension?

The dose is determined by your child's age. Always use the lowest dose that relieves symptoms and do not exceed the maximum number of doses in 24 hours. If you are unsure which dose applies to your child, ask your pharmacist before giving the medicine.

When Is the Best Time to Use Calpol Infant Sugar Free Suspension?

Give this suspension as soon as your child shows signs of fever or discomfort — there is no need to wait until symptoms become severe. It can be given with or without food, though giving it after a small feed may help reduce the chance of stomach upset in sensitive babies.

If your child wakes in the night with a fever or pain, it is appropriate to give a dose at that time, provided at least 4 hours have passed since the previous dose. Try to space doses as evenly as possible throughout the day and night to maintain consistent symptom relief.

How Long Can You Use Calpol Infant Sugar Free Suspension For?

This suspension is intended for short-term use only. For fever, seek medical advice if your child's temperature has not improved within 24 hours of starting treatment. For pain, if symptoms have not resolved within 48 hours, consult your GP or pharmacist rather than continuing to give the medicine independently.

Do not use this medicine continuously for more than a few days without medical guidance. Prolonged use without a clear diagnosis may mask symptoms of a more serious underlying condition that needs proper assessment.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Calpol Infant Sugar Free Suspension?

Paracetamol is one of the most widely used medicines for children and is generally very well tolerated when given at the correct dose. Serious side effects are rare. That said, as with any medicine, some children may experience unwanted reactions.

  • Skin rash or itching
  • Mild stomach discomfort or nausea
  • Loose stools — this may be related to the sorbitol content in the formulation

What Are the Less Common Side Effects of Calpol Infant Sugar Free Suspension?

Less common reactions occur in a small number of children and are not always directly caused by the medicine itself. If you notice any of the following, stop giving the suspension and speak to your pharmacist or GP.

  • Urticaria (hives) — raised, itchy welts on the skin
  • Flushing or redness of the skin
  • Unusual drowsiness beyond what is expected with illness
  • Changes in urine colour — very rare, but worth reporting to a doctor

What Are the Serious Side Effects of Calpol Infant Sugar Free Suspension?

Serious side effects from paracetamol at recommended doses are extremely rare. However, you should be aware of the following and act quickly if they occur. An allergic reaction (anaphylaxis) is the most significant risk, though it is uncommon. Signs include swelling of the face, lips, tongue, or throat, difficulty breathing, a sudden drop in blood pressure, or a widespread red rash. This is a medical emergency — call 999 immediately.

Liver damage is a risk only in cases of overdose, not at therapeutic doses. Never give more than the recommended amount, and never combine this suspension with any other paracetamol-containing product. If you suspect an overdose, go to A&E immediately, even if your child appears well.

What Should You Do If Your Child Experiences Side Effects?

For mild reactions such as a rash or stomach upset, stop giving the medicine and monitor your child closely. Contact your pharmacist or GP for advice on whether to continue treatment or switch to an alternative. Keep a note of when the reaction started and what dose was given — this information helps healthcare professionals assess the situation quickly.

For any sign of a serious allergic reaction or suspected overdose, do not wait — call 999 or go directly to your nearest A&E department. Take the medicine bottle with you so medical staff can see exactly what your child has taken.

Can Calpol Infant Suspension Interact With Other Medicines?

Yes — while interactions are not common, they are important to know about. The most significant risk is combining this suspension with any other product containing paracetamol, which can quickly lead to an accidental overdose. Many over-the-counter cold and flu remedies contain paracetamol, so always check the label of any other medicine you are considering giving your child at the same time.

Warfarin — an anticoagulant used in some adults — can be affected by regular paracetamol use, though this is unlikely to be relevant for most children. Medicines that affect stomach emptying, such as metoclopramide or domperidone, may alter how quickly paracetamol is absorbed. Always tell your pharmacist or GP about all medicines your child is taking before starting this suspension.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
