Making good choices: substances

Grade 10 · Health & Wellness · Free lesson

Hi there! Today we are going to explore how to make safe, healthy choices regarding over-the-counter and prescription medicines.

Medicines are powerful tools designed to help us heal, but they must be used exactly as intended. Misusing them can lead to serious health consequences.

Over-the-counter (OTC) medicines can be bought without a doctor's note, but taking too much or sharing them can damage your liver or kidneys.

Use Only as Directed

Prescription medicines are personalized specifically for one person. Sharing them is highly dangerous because doses are calculated based on a person's unique body chemistry, weight, and medical history.

Prescriptions: Locked to One Person
✏️ Worked example

Analyze the following scenario and explain the reasons why the action taken is unsafe: 'Taylor has a bad cough from a cold. Their friend offers them a leftover prescription cough syrup that was prescribed to the friend last year. Taylor decides to take it to feel better quickly.'

  1. Identify the type of medicine involved: The medicine is a prescription cough syrup, not an over-the-counter product.
  2. Analyze the personalization factor: Prescription drugs are formulated for one specific individual based on their height, weight, allergies, and current health status.
  3. Evaluate the safety risks of expired medicine: The prescription is from last year, meaning it could have lost its strength or changed chemically.
  4. Explain the decision-making process: Taking someone else's prescription bypasses a doctor's safety check. This can lead to dangerous side effects, allergic reactions, or accidental overdose.
  5. Formulate a safe alternative: Taylor should refuse the friend's medicine and instead consult a parent, guardian, or healthcare professional for an appropriate over-the-counter remedy.
