What is a Generic Drug?

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.


Tobrex is a type of eye ointment used for the treatment of different infections of the eye. Tobrex is an antibacterial medication and will only work on bacterial infections. It will not work on viral infections.

Tobrex has activity against many different types of bacteria that would infect the eye. It works by interfering with bacteria's ability to make proteins that are critical for function. By blocking the synthesis of important proteins, Tobrex causes kills the bacterial cells.


The usual directions are to apply 1-2 drops in the affected eye every four hours for most infections. If the infection is severe, your doctor may recommend administering it every 2 hours.

Warm the bottle between the hands to bring it up to room temperature before use.

Do not touch the tip of the bottle directly on the eye as this can lead to contamination of the bottle and another infection.
