The Story
What Is Calpol SixPlus Fastmelts Paracetamol?
When your child is unwell — running a temperature, complaining of a headache, or struggling with the aches that come with a cold — you want something that works quickly and that they'll actually take. Calpol SixPlus Fastmelts paracetamol are strawberry-flavoured dissolving tablets designed specifically for children aged 6 and over. Each tablet contains 250mg of paracetamol and melts directly on the tongue, meaning no water is needed and no fuss at the medicine cabinet. You can find a wider range of children's remedies in our baby and toddler collection.
Paracetamol is one of the most widely used medicines in the UK for managing mild to moderate pain and fever in children. The NHS recommends paracetamol as a first-line option for reducing high temperature and relieving discomfort in children. The Fastmelts format is particularly useful for children who struggle to swallow tablets or who refuse liquid medicines — a genuinely common challenge for parents of school-age kids.
How Do Calpol SixPlus Fastmelts Work to Relieve Pain and Fever?
Paracetamol works centrally and peripherally to reduce pain and temperature. Here's a simple breakdown of the mechanism:
- Paracetamol inhibits the synthesis of prostaglandins — chemical messengers that sensitise nerve endings to pain and trigger the hypothalamus to raise body temperature.
- By reducing prostaglandin activity in the central nervous system, paracetamol raises the pain threshold, making discomfort feel less intense.
- It acts on the hypothalamus — the brain's temperature-regulating centre — to bring a fever down towards a normal range.
- The dissolving tablet format allows rapid disintegration on the tongue, which may support faster absorption compared to swallowing a whole tablet.
It's worth noting that paracetamol does not treat the underlying cause of illness — it manages symptoms. If your child's fever persists beyond 48 hours or worsens, always seek medical advice.
Who Is Calpol SixPlus Fastmelts Suitable For?
These tablets are intended for children aged 6 to 12 years. They're particularly well suited to children who:
- Have difficulty swallowing tablets or capsules
- Refuse liquid paracetamol formulations
- Need pain or fever relief at school or on the go, where measuring liquid medicine isn't practical
- Are experiencing mild to moderate pain from headaches, toothache, sore throats, or cold and flu symptoms
They are not suitable for children under 6 years of age. Children with known hypersensitivity to paracetamol or any of the excipients should not use this product. If your child has liver or kidney problems, always speak to a GP or pharmacist before use.

Frequently Asked Questions
Where can I buy Calpol SixPlus Fastmelts paracetamol online in the UK?
You can buy Calpol SixPlus Fastmelts paracetamol online directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. Simply add the 24-pack to your basket and proceed to checkout for fast, discreet UK dispatch. No prescription is required as this is a General Sale List medicine.
How do Calpol SixPlus Fastmelts work in the body?
Each tablet contains 250mg of paracetamol, which works by inhibiting prostaglandin synthesis in the central nervous system. This reduces the brain's pain signalling and acts on the hypothalamus to lower elevated body temperature. The dissolving format means the tablet breaks down quickly on the tongue, supporting prompt absorption.
How do I use Calpol SixPlus Fastmelts step by step?
Using Calpol SixPlus Fastmelts is straightforward. Follow these steps:
- Check your child's age to confirm the correct dose.
- Place the tablets directly on your child's tongue.
- Allow them to dissolve fully — no water is needed.
- Wait at least 4 hours before giving the next dose, and give no more than 4 doses in 24 hours.
If symptoms do not improve within 48 hours, consult a GP or pharmacist.
What is the correct dose of Calpol SixPlus Fastmelts for my child?
Children aged 6 to 9 years should take 2 tablets per dose, while children aged 10 to 12 years should take 3 tablets per dose. Doses should be spaced at least 4 hours apart, with a maximum of 4 doses in any 24-hour period. Never exceed the recommended dose, and do not use in children under 6 years.
When is the best time to give Calpol SixPlus Fastmelts to my child?
Give a dose as soon as your child begins to show signs of pain or fever — there is no specific time of day that is clinically superior. What matters most is maintaining adequate spacing of at least 4 hours between doses. If your child wakes in the night with a high temperature, it is appropriate to give a dose at that time provided the 4-hour interval has passed.
What are the side effects of Calpol SixPlus Fastmelts?
Side effects are uncommon when the medicine is used as directed. Possible side effects include:
- Nausea or stomach discomfort
- Skin rash or itching (rare)
- Allergic reactions such as facial swelling — seek emergency help immediately if this occurs
Liver damage is only a risk in cases of overdose, not with correct therapeutic use.
Can I give Calpol SixPlus Fastmelts to a child under 6?
No — Calpol SixPlus Fastmelts are not suitable for children under 6 years of age. For younger children, age-appropriate paracetamol formulations such as Calpol Infant Suspension are available. Speak to your pharmacist for guidance on the right product for your child's age and weight.
What happens if my child accidentally takes too many tablets?
Paracetamol overdose is a medical emergency. Even if your child appears well, excess paracetamol can cause serious liver damage that may not be immediately apparent. Go to your nearest A&E department immediately or call 999 — do not wait for symptoms to develop. Take the packaging with you so medical staff can see exactly what was taken.
Can Calpol SixPlus Fastmelts be used alongside other medicines?
Do not use these tablets alongside any other product containing paracetamol, including many cold and flu remedies, as this risks accidental overdose. Paracetamol may also interact with warfarin if used regularly. Always check with your pharmacist before combining medicines — you can also browse our cold and flu collection for compatible products.
Who is not eligible to use Calpol SixPlus Fastmelts?
These tablets are not suitable for:
- Children under 6 years of age
- Children with known allergy to paracetamol or any tablet ingredient
- Children with phenylketonuria — the tablets contain aspartame
- Children already taking another paracetamol-containing medicine
Always read the full patient information leaflet before use.
What are the alternatives to Calpol SixPlus Fastmelts?
Alternatives for children aged 6 and over include Calpol SixPlus Suspension (liquid paracetamol), ibuprofen-based products such as Nurofen for Children (if appropriate and not contraindicated), or generic paracetamol tablets. The right choice depends on your child's age, weight, and any underlying health conditions — your pharmacist can advise. You can explore options in our baby and toddler collection.
How long can my child use Calpol SixPlus Fastmelts for?
For pain relief, do not use for more than 3 days without seeking medical advice. For fever, do not use for more than 48 hours without consulting a GP or pharmacist. If symptoms persist or worsen, this may indicate an underlying condition that requires professional assessment rather than continued self-treatment.
Do Calpol SixPlus Fastmelts contain sugar or allergens?
Calpol SixPlus Fastmelts are sugar-free, which makes them suitable for children who need to limit sugar intake. However, they do contain aspartame, a source of phenylalanine, so they are not suitable for children with phenylketonuria. Always check the full ingredients list on the packaging if your child has known allergies or intolerances.
What is the latest guidance on using paracetamol for children's fever?
Current NHS guidance recommends paracetamol as a first-line option for managing fever and discomfort in children, used only when the child is distressed — not simply because a temperature is elevated. The goal is to improve your child's comfort, not to normalise the thermometer reading. Alternating paracetamol and ibuprofen is not routinely recommended unless advised by a healthcare professional.
How should I manage my child's side effects from Calpol SixPlus Fastmelts?
If your child experiences mild nausea, try giving the dose after a small amount of food. For any skin reaction such as a rash or itching, stop the medicine immediately and contact your GP. If your child shows signs of a serious allergic reaction — including swelling of the face or difficulty breathing — call 999 without delay. For general health queries, our pain relief collection page includes further guidance on managing children's symptoms safely.
