Over-the-counter does not mean harmless

Some medicines can be bought at a chemist without a prescription. They are safe when used as the label or pharmacist says, but too much can cause serious harm.

Many cold, flu and pain products contain the same ingredients. Taking two products together can mean taking too much of one ingredient without realising.

Always check with a parent, pharmacist or doctor before taking any medicine.

Reading the label

Check the name of the medicine, its active ingredients, how much and how often to take, the age it is meant for, the warnings and the expiry date.

Do not take medicine after its expiry date, and keep medicines in their original packs, away from heat and out of reach of small children.

Prescriptions are personal

A prescription is written for one person, based on their age, weight, health and other medicines. Never take someone else's prescription medicine, and never share yours.

Tell your doctor about all medicines, home remedies and products you take, because some can interact.

Antibiotics: only when a doctor prescribes

Antibiotics treat infections caused by bacteria. They do not work against viruses, which cause colds, most coughs and sore throats, and flu.

Taking antibiotics when you do not need them can cause side effects and helps bacteria become resistant, so antibiotics may not work when you really need them.

Only take antibiotics when a doctor prescribes them, take them exactly as told, and do not save leftovers or share them.

Key points

  • Over-the-counter medicines can still cause harm if misused.
  • Read the label: ingredients, how to take, warnings, expiry.
  • Never share prescription medicines.
  • Antibiotics do not cure colds or flu.
  • Take antibiotics only when prescribed, exactly as told.

Myth or fact?

Myth

Antibiotics cure colds and coughs.

Fact

Most colds and coughs are caused by viruses, which antibiotics cannot kill. Rest, fluids and time usually help.

Myth

If one tablet helps, two will work twice as fast.

Fact

Taking more than the label or doctor says does not help faster and can be dangerous.

Myth

Chemist shop advice is the same as a doctor's prescription.

Fact

Pharmacists are knowledgeable, but some conditions need a doctor to examine you. Ask a doctor if symptoms are severe or not getting better.

When to get help

  • If someone has taken too much medicine, even if they seem fine, get medical help immediately or call 112.
  • Ask a pharmacist or doctor if you are unsure how to take a medicine.
  • If you have a rash, swelling or trouble breathing after a medicine, get emergency help.
