Giving medicine to children safely
Children are dosed by weight, not by age, and the margin for error is narrower. The rules that prevent the most common mistakes.
Weight, not age, not a spoon
Paediatric doses are calculated from body weight. Age bands on packaging are a rough guide that assumes an average-sized child, and children of the same age vary enormously. If you know the weight, use it, and ask the pharmacist to work out the dose.
Paediatric formulations also come in different strengths of the same medicine. Reading the concentration on the bottle rather than assuming it matches the last one is a habit worth building.
The rules that prevent the common harms
- Never give aspirin to a child with a viral illness — it is linked to Reye's syndrome. Check combination cold and flu products, where it is not always obvious.
- Do not give cough and cold remedies to young children. They do not work and have caused harm; national and international guidance advises against them under six.
- Never give an adult formulation, and never split an adult tablet to guess a child's dose.
- Do not give one child's prescription to another child.
- Check whether an anti-inflammatory is appropriate — it is generally avoided in a dehydrated child, in chickenpox, and in some kidney conditions.
- Write down what was given and when, especially when two adults are sharing care overnight. Double-dosing usually happens this way.
The everyday ones, dosed by weight:
Paracetamol — Panado, Painamol, Tylenol, Pacimol
Mild to moderate pain; fever
Ibuprofen — Nurofen, Brufen, Advil, Ibupain
Mild to moderate pain; inflammation; fever; dysmenorrhoea
Oral Rehydration Salts (ORS) — Rehidrat, ORS sachets, Dioralyte, Electrolit
Dehydration due to diarrhoea or vomiting
Zinc Sulphate — Zinplex, Zincovit
Zinc deficiency; adjunct in diarrhoea (children); wound healing; immune support
Getting it into them
- Use a syringe aimed at the inside of the cheek, not the back of the throat, and give it slowly in small amounts.
- Sit the child upright. Never medicate a lying-down or sleeping child.
- Do not mix a dose into a full bottle or cup — if they do not finish it, you cannot know how much they had.
- Be honest that it may taste unpleasant rather than calling it sweets, which is exactly the association that leads to accidental poisoning.
- For an older child, offer limited choices — which drink afterwards, sitting where — rather than whether to take it.
- Ask the pharmacist about a different flavour or formulation if a medicine is consistently refused.
Storage and emergencies
- Store everything locked or high up and out of sight — children climb, and 'out of reach' is a moving target.
- Keep medicines in their original containers with the labels intact.
- Iron tablets are a leading cause of poisoning deaths in small children and look like sweets.
- Handbags and bedside tables are where visitors' medicines end up, and are a common source.
- Return unused and expired medicines to a pharmacy.
Common questions
- Can I give half an adult tablet?
- Not unless a clinician has specifically told you to. Doses are not simply proportional, some tablets must not be split or crushed, and paediatric formulations exist for good reason. Ask a pharmacist.
- The child vomited straight after the dose. Do I repeat it?
- It depends on the medicine and how long afterwards. Ask a pharmacist or clinic rather than guessing — repeating risks a double dose, and skipping matters more for some medicines than others.
- Are antibiotics needed for a child's cough or cold?
- Almost never — these are viral. Antibiotics do not help, cause side effects and contribute to resistance. A cough lasting more than two weeks, difficulty breathing or a very unwell child needs assessment, not a request for antibiotics.
