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.

    Caverject Impulse Kit

    The Caverject Impulse Kit (alprostadil) is used for the treatment of problems related to male sexual functions, specifically erectile dysfunction. It’s able to aid with proper blood flow to the penis to achieve as well as maintain an erection.

    You can buy Caverject as a disposable, single-dose, dual-chamber syringe system. It includes a glass cartridge which has sterile, freeze-dried alprostadil present in the front chamber. The rear chamber has sterile bacteriostatic water for injection. Take note that the alprostadil should be reconstituted using the provided sterile bacteriostatic water just before injection.


    The first administration of Caverject should be under the professional supervision of a healthcare provider. Self-administration requires proper training. The individual dose is determined by the doctor.

    After proper training, self-administration at home can be done. It’s recommended to not use Caverject more than 3 times a week. There should be at least a 24 hours gap between doses.
