What is an Adverse Drug Event?

When medicines cause harm — what you need to know

💊

Medicines can be safe…

…when taken exactly as prescribed. Always follow your doctor’s or pharmacist’s instructions on dose, timing, and method.

⚠️

Adverse Drug Event (ADE)

An ADE is when a medicine causes harm to the person taking it. It can happen through misuse, sharing, or mixing with alcohol.

🙅

Never share prescriptions

A medicine prescribed for someone else may be wrong for your body — even if it helped them, it could seriously hurt you.

🍺

Alcohol + Medicine = Danger

Mixing alcohol with medication can cause dangerous, unpredictable reactions. Always check before combining anything.

📦

Storage matters too

Medicines stored incorrectly — too warm, too damp, in direct sunlight — can lose potency or become harmful.

👶

Lock medicines away

Keep all medicines out of reach of children. Even vitamins and supplements can be dangerous if a young child takes too many.

👤Taking someone else’s prescription
A medicine not prescribed for you can cause an ADE — your body may react very differently.

Sharing — even with the same symptoms — can cause serious harm. Every body is different.
🤧Misusing cold medicine or stimulants
Taking these when you don’t need them is misuse and a direct path to an adverse drug event.
🍷Drinking alcohol while on medication
Alcohol can make medicines too strong, too weak, or dangerously unpredictable. Always check first.

💬 5 Questions to Always Ask

Before you take any new medicine, ask your doctor or pharmacist these five questions — every single time.

Know Your Meds

Before you take it, ask these 5 questions

1

What is this medicine for?

Understanding its purpose helps you take it correctly and spot any early problems.

2

When and how should I take it?

Ask about dose, timing, and whether it must be taken with food, water, or at a specific time of day.

3

How should I store it?

Some medicines must be kept cool, dry, or away from light to stay effective and safe.

4

Can it interact with other medicines or foods?

Bring all your medicines to every appointment. Even grapefruit juice can cause dangerous interactions with certain medicines.

5

What are the side effects?

Know what to expect — and which symptoms should make you contact your doctor right away.

🍊

Food can also interact with medicines!

Grapefruit juice, dairy, and even some herbal teas can affect how your body processes medication. Always ask your pharmacist about food interactions.

Safety Tips

4 habits that keep you safe — tap to expand

Before taking any medicine — even one you’ve taken before — read the label or instructions carefully. Doses and directions can change between prescriptions, and “close enough” is never good enough with medication.
Take the right dose, at the right time, in the right way. If the label says with food — take it with food. If it says twice daily — take it twice daily. Skipping doses or doubling up can both cause problems.
Bring all your medicines — prescription and over-the-counter — to every doctor or pharmacist visit. This lets them check for dangerous interactions and make sure everything you’re taking is still right for you.
If you feel unwell after starting a new medicine, tell your doctor or pharmacist straight away — don’t just stop taking it without advice. Side effects can also be reported formally through the WHO VigiFlow system at the bottom of this page.
