What Is Calpol Infant Suspension and How Does It Help?

 

When your little one is running a temperature or clearly uncomfortable, you want something you can trust — fast. Calpol infant suspension is one of the most widely recognised children's medicines in the UK, and for good reason. This 100ml bottle contains paracetamol 120mg per 5ml in a sugar-free, strawberry-flavoured liquid that's gentle enough for babies from 2 months of age. It's used to relieve mild to moderate pain and to bring down a fever, making it a genuine staple in any family medicine cabinet. You can find it alongside other trusted products in our baby and toddler range.

Paracetamol has been used safely in children for decades, and the NHS recommends it as a first-line option for managing fever and pain in infants and young children. The suspension format makes it easy to measure and administer — no tablets, no fuss.

 

How Does Calpol Infant Suspension Work to Reduce Fever and Pain?

 

Paracetamol — the active ingredient in this suspension — works by inhibiting the synthesis of prostaglandins in the central nervous system. Prostaglandins are chemical messengers that play a key role in triggering both pain signals and the rise in body temperature we call fever. By reducing their production, paracetamol helps to:

  • Lower an elevated body temperature (antipyretic effect)
  • Reduce the perception of mild to moderate pain (analgesic effect)
  • Provide relief within 15 to 30 minutes of administration
  • Offer effects that typically last 4 to 6 hours

It does not treat the underlying cause of a fever or infection — it manages the symptoms. If your child's fever persists beyond 48 hours or worsens, always seek medical advice.

 

Who Is Calpol Infant Suspension Suitable For?

 

This suspension is designed specifically for infants and young children. It is suitable for:

  • Babies aged 2 months and over (up to 6 years — for older children, Calpol Six Plus is more appropriate)
  • Infants experiencing post-vaccination fever (from 2 months)
  • Children with teething pain, earache, sore throat, or cold-related discomfort
  • Children who cannot swallow tablets or capsules

It is not suitable for babies under 2 months of age. Children with known hypersensitivity to paracetamol or any other ingredient in the formulation should not use this product. If your child has liver or kidney problems, speak to your GP or pharmacist before use.

Is Calpol Infant Suspension Safe to Store at Home?

 

Yes — provided you follow a few simple guidelines. Store the bottle below 25°C in a dry place, away from direct sunlight. Do not refrigerate it, as this can affect the consistency of the suspension. Always keep it out of the reach and sight of children, and make sure the cap is tightly closed after each use. Once opened, use within the period stated on the packaging.

If you're building up your home medicine supplies, our first aid collection has everything you might need alongside this suspension — from plasters to antiseptic wipes. And remember: Calpol infant suspension should always be stored safely and used strictly according to the dosing instructions.

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 Calpol Infant Suspension 100ml

 

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

 

Calpol Infant Suspension is an oral paracetamol liquid containing 120mg of paracetamol per 5ml. It is used to relieve mild to moderate pain in infants and young children — including teething pain, earache, sore throat, headache, and aches associated with colds and flu. It is also used to reduce fever, including fever that can occur after routine childhood vaccinations. The suspension is sugar-free and strawberry-flavoured, making it easier to give to young children who may resist medicine.

This product is licensed for use in children from 2 months of age. For post-immunisation fever in babies aged 2 to 3 months, no more than two doses should be given, and medical advice should be sought if further doses are needed.

 

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

 

Before giving this suspension to your child, read the following carefully. Do not use Calpol Infant Suspension if your child:

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

Speak to your doctor or pharmacist before use if your child has liver problems, kidney problems, or is malnourished. The following medicines may interact with paracetamol:

  • Warfarin and other anticoagulants (regular paracetamol use may increase bleeding risk)
  • Other paracetamol-containing products (risk of overdose)
  • Metoclopramide or domperidone (may affect how quickly paracetamol is absorbed)
  • Cholestyramine (may reduce paracetamol absorption if taken within one hour)

 

How Should You Use Calpol Infant Suspension Correctly?

 

  1. Shake the bottle well before each use.
  2. Use the measuring syringe or spoon provided — never use a household teaspoon, as this is not accurate enough.
  3. Measure the correct dose for your child's age (see table below).
  4. Give the suspension by mouth, directly or mixed with a small amount of water or milk if needed.
  5. Leave at least 4 hours between doses.
  6. Do not give more than 4 doses in any 24-hour period.
  7. If symptoms persist beyond 48 hours, consult your GP.
Age Dose Maximum doses per 24 hours
2–3 months (post-immunisation only) 2.5ml 2 doses only
3–6 months 2.5ml 4
6–24 months 5ml 4
2–4 years 7.5ml 4
4–6 years 10ml 4

If you're also managing your child's cold symptoms, our cold and flu collection includes additional products that may help support recovery alongside this suspension.

 

What Are the Possible Side Effects of Calpol Infant Suspension?

 

When used at the correct dose, side effects are uncommon. However, as with all medicines, reactions can occur. Monitor your child after each dose.

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

  • Skin rash or redness
  • Mild stomach upset

Less common or rare side effects:

  • Allergic reactions including swelling of the face, lips, or throat
  • Difficulty breathing (seek emergency help immediately)
  • Serious skin reactions such as Stevens-Johnson syndrome (very rare)
  • Blood disorders (with prolonged or excessive use)

If you notice any serious reaction, stop giving the medicine and seek medical attention straight away. Never exceed the recommended dose — paracetamol overdose can cause serious liver damage, even if your child appears well initially.

 

How Should You Store Calpol Infant Suspension Safely?

 

Proper storage keeps the medicine effective and safe. Follow these guidelines:

  • Store below 25°C in a dry place
  • Do not refrigerate
  • Keep the bottle tightly closed when not in use
  • Keep out of the reach and sight of children at all times
  • Do not use after the expiry date printed on the bottle
  • Do not dispose of medicines via wastewater or household waste — return unused medicine to your pharmacist

Frequently Asked Questions

Where can I buy Calpol Infant Suspension online in the UK?

You can buy Calpol Infant Suspension 100ml directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as a General Sale List medicine. Simply add it to your basket and it will be dispatched to your door.

How does Calpol Infant Suspension work in the body?

Calpol Infant Suspension contains paracetamol, which works by reducing the production of prostaglandins — chemicals in the brain that trigger pain signals and raise body temperature. This dual action means it both relieves discomfort and brings down a fever. It does not treat the underlying cause of illness, only the symptoms.

What age can babies start having Calpol Infant Suspension?

Calpol Infant 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-immunisation fever, and no more than two doses should be given. If you are unsure whether it is appropriate for your baby, speak to your health visitor or GP before use.

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

The dose depends on your child's age. Babies aged 3 to 6 months receive 2.5ml, children aged 6 to 24 months receive 5ml, children aged 2 to 4 years receive 7.5ml, and children aged 4 to 6 years receive 10ml. Always use the measuring syringe provided and never exceed 4 doses in 24 hours.

How often can I give Calpol Infant Suspension to my child?

You can give Calpol Infant Suspension every 4 to 6 hours as needed, but never more than 4 doses in any 24-hour period. Always leave at least 4 hours between doses. If your child still has a fever or pain after 48 hours, contact your GP.

Can I give Calpol Infant Suspension alongside other medicines?

Do not give Calpol Infant Suspension at the same time as any other medicine containing paracetamol, as this significantly increases the risk of overdose. Always check with your pharmacist before combining it with any other medication. If your child is on regular prescribed medicines, seek medical advice first.

What are the side effects of Calpol Infant Suspension?

Side effects are uncommon when the correct dose is used. Possible reactions include skin rash, mild stomach upset, or in rare cases, allergic reactions such as swelling of the face or difficulty breathing. If you notice any serious reaction, stop the medicine immediately and seek urgent medical attention.

What should I do if I accidentally give my child too much Calpol?

If you think your child has received too much paracetamol, go to your nearest A&E or call 999 immediately — even if your child seems well, as overdose symptoms can be delayed. Paracetamol overdose can cause serious liver damage. Take the medicine packaging with you so medical staff can see exactly what was given.

Is Calpol Infant Suspension sugar-free?

Yes, Calpol Infant Suspension is sugar-free, which makes it suitable for children who need to limit their sugar intake. It is also colour-free in some formulations — check the packaging for the specific version you have purchased. The strawberry flavour is achieved without added sugar.

Can I give Calpol Infant Suspension to my child after vaccinations?

Yes — the NHS recommends paracetamol suspension to manage post-immunisation fever in babies from 2 months of age. For babies aged 2 to 3 months, give one dose of 2.5ml after the vaccination, and a second dose 4 to 6 hours later if needed. Do not give more than two doses for this purpose without medical advice.

What are the alternatives to Calpol Infant Suspension?

Alternatives include other paracetamol-based infant suspensions such as Medinol or own-brand pharmacy versions, all containing 120mg/5ml paracetamol. Ibuprofen suspension (e.g. Nurofen for Children) is another option for children over 3 months, but it works differently and has different contraindications. You can explore our baby and toddler range for available options.

How long can I use Calpol Infant Suspension for?

Calpol Infant Suspension should not be used for more than 3 days without seeking medical advice. If your child's fever or pain persists beyond this point, or if symptoms worsen at any stage, consult your GP. It is intended for short-term symptom relief, not ongoing treatment.

How should I store Calpol Infant Suspension at home?

Store Calpol Infant Suspension below 25°C in a dry place — do not put it in the fridge. Keep the bottle tightly closed and always store it out of the reach and sight of children. Check the expiry date before each use and return any unused medicine to your pharmacist for safe disposal.

Is Calpol Infant Suspension suitable for children with allergies?

Calpol Infant Suspension does not contain gluten, lactose, or aspirin. However, it does contain some excipients including maltitol liquid and acesulfame potassium — always check the full ingredients list on the packaging if your child has known allergies or intolerances. If you are unsure, speak to your pharmacist before use. For allergy-related concerns in children, our allergy and hay fever collection may also be helpful.

What is the latest guidance on using paracetamol in children?

Current NHS and NICE guidance supports the use of paracetamol as a first-line treatment for fever and mild to moderate pain in children, provided it is used at the correct dose and for the shortest time necessary. Routine use to prevent fever after vaccination is no longer recommended — it should only be used if fever actually develops. Always follow the most up-to-date advice from your GP or pharmacist.

How Should You Use Calpol Infant Suspension?

Always read the patient information leaflet before giving this medicine to your child. Shake the bottle well before each use to ensure the suspension is evenly mixed. Use only the measuring syringe or spoon supplied with the product — household teaspoons vary in size and will not give an accurate dose.

If your child spits out the dose or vomits immediately after taking it, do not give another dose straight away. Wait and observe, then seek pharmacist advice if you are unsure whether to re-dose.

What Is the Correct Dose of Calpol Infant Suspension?

The dose is determined by your child's age. Never exceed the maximum number of doses in a 24-hour period, and always leave at least 4 hours between doses. If your child is small or large for their age, speak to your pharmacist or GP about the most appropriate dose.

When Is the Best Time to Use Calpol Infant Suspension?

Give Calpol Infant 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 younger babies. If your child wakes in the night with a fever, it is appropriate to give a dose at that time, provided at least 4 hours have passed since the last dose.

For post-vaccination fever, give the first dose as soon as the fever develops — not routinely before or immediately after the injection unless fever is already present.

How Long Can You Use Calpol Infant Suspension For?

This suspension is intended for short-term use only. Do not use it for more than 3 consecutive days without seeking medical advice. If your child's fever or pain has not improved within 48 hours, or if symptoms worsen at any point, contact your GP. Prolonged or excessive use of paracetamol can cause liver damage, so it is important to stick to the recommended dose and duration.

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

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

When used at the correct dose, Calpol Infant Suspension is generally very well tolerated by infants and young children. Serious side effects are rare. However, as with all medicines, some children may experience reactions. The most commonly reported effects include:

  • Skin rash or mild redness
  • Mild stomach discomfort or nausea
  • Loose stools in some infants

These effects are usually mild and resolve on their own. If your child develops a rash after taking this medicine, stop use and speak to your pharmacist or GP.

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

Less common reactions occur in a small number of children and may require medical attention. Be alert to the following:

  • Urticaria (hives) — raised, itchy welts on the skin
  • Swelling of the face, lips, tongue, or throat (angioedema)
  • Difficulty breathing or wheezing
  • Unusual bruising or bleeding (with prolonged or excessive use)
  • Changes in urine colour (dark urine may indicate liver stress)

If you notice any of these symptoms, stop giving the medicine immediately and seek medical advice promptly.

What Are the Serious Side Effects of Calpol Infant Suspension?

Serious side effects are very rare when the medicine is used correctly. However, paracetamol overdose — even accidental — can cause severe and potentially life-threatening liver damage. Symptoms of overdose may not appear immediately and can be delayed by 24 hours or more. If you suspect your child has taken too much, go to A&E immediately or call 999, even if they appear well.

In extremely rare cases, paracetamol has been associated with serious skin reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. These present as painful blistering or peeling of the skin and require emergency medical treatment. Stop the medicine at once if any unusual skin changes occur.

Can Calpol Infant Suspension Interact With Other Medicines?

Yes — certain medicines can interact with paracetamol. The most important interaction to be aware of is with other paracetamol-containing products. Many cold and flu remedies, teething gels, and combination medicines contain paracetamol, so always check labels carefully before giving more than one product at a time. Other notable interactions include:

  • Warfarin — regular paracetamol use may enhance anticoagulant effects
  • Metoclopramide or domperidone — may speed up paracetamol absorption
  • Cholestyramine — may reduce paracetamol absorption if taken within one hour

Always tell your pharmacist or GP about all medicines your child is currently taking before starting Calpol Infant Suspension.

What Should You Do If Your Child Experiences Side Effects?

For mild reactions such as a rash or stomach upset, stop the medicine and monitor your child closely. Contact your pharmacist for advice on whether to continue or switch to an alternative. For any sign of a serious allergic reaction — including swelling, breathing difficulty, or collapse — call 999 immediately. You can also report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

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