Babies can usually have Calpol (infant paracetamol) from 2 months of age, but only in specific doses and situations, and never under 2 months unless a doctor prescribes it. Always check the exact product label and speak to a health professional if unsure, especially for very young or premature babies.

When can babies have Calpol?

  • Most infant Calpol syrups are licensed from 2 months of age.
  • It should not be given to babies under 2 months unless a doctor specifically says so.
  • At 2–3 months, dosing is stricter and often limited to a maximum of 2 doses in 24 hours so that serious infections are not masked.

For 2–3‑month‑olds, it is often first used around routine vaccinations, following the exact dosing schedule on the pack or from your nurse/doctor.

Typical age‑based dosing (infant suspension)

Below is a general guide for standard sugar‑free Calpol infant suspension (always confirm against your own bottle and with a pharmacist, as products and strengths can differ).

Important safety points

  • Always use the supplied syringe or spoon to measure – household teaspoons are inaccurate.
  • Leave at least 4 hours between doses and never give more than 4 doses in 24 hours (or more than 2 doses in 2–3‑month‑olds, as stated on many labels).
  • Do not combine other paracetamol‑containing medicines with Calpol, to avoid overdose.
  • Seek urgent medical advice if:
    • Your baby is under 3 months and has a temperature of 38°C or higher, or
    • Under 6 months with a temperature of 39°C or higher, or
    • They are hard to wake, breathing fast, not feeding, have a rash, or you are worried.

Vaccinations and Calpol

  • Calpol is often used after routine baby vaccinations from 2 months to help with fever or discomfort.
  • There are specific schedules (e.g., a dose soon after vaccination and further doses 4–6 hours apart) that must match the leaflet from your clinic or the product.

Quick checklist for parents

Before giving Calpol, check:

  1. Age – is your baby at least 2 months old?
  1. Weight & gestation – for 2–3‑month‑olds, usually must be over 4 kg and born after 37 weeks.
  1. Correct product strength – infant suspension vs older‑child products.
  1. Total doses in last 24 hours.
  1. Any other medicines containing paracetamol.

If there is ever uncertainty, or your baby is very young, premature, or has other medical conditions, contact a pharmacist, GP, or emergency service for personalised advice.
