Calpol Infant Suspension (Sugar Free)
5.5/10 overall£4.00
A paracetamol-based liquid medicine for reducing fever and mild-to-moderate pain from 2 months.
The verdict
Calpol Infant Suspension is a sugar-free, paracetamol-based liquid medicine and the NHS-recommended first-line option for reducing fever and easing mild-to-moderate pain in babies from 2 months and 4kg. It includes an accurate dosing syringe, but must be dosed exactly by weight and age, and treats symptoms only.
Calpol's paracetamol suspension is one of the most commonly stocked medicine-cabinet items for a reason: it's the NHS-recommended first-line option for reducing fever and easing mild-to-moderate pain (post-vaccination soreness, teething discomfort) in babies from 2 months, provided they weigh at least 4kg.
Dosing must be by weight and age exactly as printed on the pack or as advised by a pharmacist or GP — the NHS is explicit that you should never give more than the stated dose or dose more frequently than recommended, and should always use the syringe provided rather than a kitchen spoon for accuracy.
It treats symptoms (fever, pain) rather than any underlying cause, and the NHS advises seeking medical advice if a fever persists beyond a few days, if your baby is under 3 months and has any fever at all, or if you're at all unsure — this is a first-aid tool, not a substitute for medical assessment when something seems seriously wrong.
