Brand, Generic, Strength, Dose: Four Medicine Terms Every Patient Should Know

Medicine conversations are easier when four common terms are clear. The brand name is a manufacturer’s marketed name. The generic name identifies the active ingredient. Strength describes how much active ingredient is in a tablet, capsule, millilitre, puff, patch, or other unit. Dose is the amount you are instructed to take at one time or over a defined period.

Two bottles can contain the same active ingredient but different strengths. Two products can share a similar name but use a different release mechanism. “Extended release,” “delayed release,” liquid concentration, dosage form, and route all matter.

Use a read-back

When a product changes, read the full label back to the pharmacist: active ingredient, strength, form, and directions. Ask why the appearance or manufacturer changed and whether any inactive ingredients matter for your allergies or sensitivities.

Never identify a medicine by color or shape alone. Appearance can vary by manufacturer and country.
