The difference in plain language
Brand name is the name on the box. Active ingredient is what actually produces the effect. Two products may look different and have different names, but contain the same active ingredient in the same strength.
When it’s especially useful
- Pharmacy substitutions: you can verify it’s the same treatment.
- Travel and international care: brand names change across countries.
- Complex medication regimens: reduces confusion and accidental duplication.
How to write it
A simple and readable format is:
- Brand name — active ingredient
- Strength
- Dosage + schedule
- Notes when needed
Example: “Zyrtec — cetirizine 10 mg, 1 tablet at night”.
Strength and schedule still matter most
Even with the correct active ingredient, the strength and dosage determine how much you take. Always include strength and schedule so the list can be used safely.
FAQ
Do I have to list active ingredients for every medicine?
No. It’s optional, but helpful if substitutions are common or if you travel.
How do I find the active ingredient?
It’s typically listed on the package, leaflet, or can be confirmed by a pharmacy.
If I only list brand names, is that still useful?
Yes, especially if the list includes strength, dosage, and schedule. Adding active ingredients simply adds extra resilience.
