Making good choices: substances

Grade 9 · Health & Wellness · Free lesson

Hi! I'm Studyfin, your tutor. Today we are going to learn how to make safe, healthy choices about medicines.

Medicines are powerful tools that help us heal. However, using them incorrectly can harm our bodies. We must understand the difference between over-the-counter (OTC) drugs and prescription drugs.

Over-the-counter drugs are bought without a doctor's note. Even though they are easy to buy, misusing them by taking too much can damage your organs, like your liver.

OTC

Prescription drugs are specially ordered by a doctor for one specific person. Sharing these drugs is highly dangerous because doses are customized based on a person's weight, age, and medical history.

Rx Only
✏️ Worked example

Imagine your friend has a bad cough and offers you some of their prescription cough syrup. Let's explain the top reasons why you must refuse this offer.

  1. Identify the type of drug: Prescription cough syrup is prescribed only for your friend's specific body and illness.
  2. Analyze the physical risks: The syrup might contain strong ingredients that could cause an allergic reaction or interact badly with your own body chemistry.
  3. Evaluate the dosage: The doctor calculated the dose based on your friend's exact weight and age, which might be too strong or dangerous for you.
  4. Formulate your response: Politely decline and explain that sharing prescription medicine is unsafe because doctors must customize each treatment plan.
