A generic medicine contains the same active ingredient, in the same strength and dosage form, as the original brand. It is required to work the same way in the body, so for most people it provides the same effect.
The main difference is usually price. Because generic makers do not carry the original research and marketing costs, the same molecule can cost significantly less. That can make long-term treatment far more affordable.
If you are switching between a brand and a generic, it is still worth a quick word with your pharmacist — especially for medicines where small differences matter. Our catalogue shows the generic name on every product so you can compare your options easily.
