A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Zyrtec is an allergy treatment medication used for relief from cold or allergy symptoms, and it may also be used to treat hives or other conditions that cause extreme itching in the skin. Cetirizine is an effective antihistamine that disables the immune system’s production of the histamines that cause the symptoms of an allergic reaction. It is a good choice for seasonal allergies or pet allergies and you can buy Zyrtec without a prescription here at Canpharm.
