The right amount of a medicine — Chemistry, 4–6 years
A medicine works because its substances change something in the body. The amount matters: the same substance can help in one dose and be harmful in too much.
A medicine needs the right dose
A medicine contains substances that can change how the body works, such as lowering a fever or easing pain. It must be taken in the amount and way an adult or health professional says, because more is not automatically better.
Why does the amount matter?
The body can use or remove only a certain amount at a time. A measured dose solves two problems together: too little may not help, while too much can put extra strain on the body.
Measuring 5 millilitres
Suppose a label, read by an adult, says ‘5 millilitres’. First, find the 5 ml mark on the measuring spoon or syringe. Next, fill only to that mark, check it carefully, and take it as directed; do not add another spoon because it tastes sweet.
More is not better
A child may reasonably think that twice the medicine will make a headache disappear twice as fast. But the body does not work like a simple counting game: an extra amount can cause harm, so medicines are never shared or taken by guesswork.
A safe everyday rule
At home, medicines belong with a trusted adult, even when they are in a colourful bottle or taste like fruit. If someone offers one, or if you find one, stop and ask an adult; only the label and a health professional can guide its use.
