No. Brand drugs are developed under patent protection that lasts 20 years. In most cases, generic drug companies apply to Health Canada to sell a generic version after the brand drug's patent(s) expire.
Over the next few years, as more patents expire, generic versions of several top-selling brand name drugs are expected to become available, giving you access to even more affordable medicines.
Ask your doctor or pharmacist if a generic version of your brand prescription is available.
