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.

Description

Heartgard Plus offers a convenient and effective solution for preventing heartworm disease in dogs, providing peace of mind, and ensuring the health and well-being of their canine companions. However, it is important to administer the medication as a veterinarian directs and monitors for potential adverse reactions.

Heartgard Plus is a veterinary medication specifically formulated to prevent dog heartworm disease. It combines two active ingredients: ivermectin and pyrantel pamoate. Ivermectin is a broad-spectrum antiparasitic medication that works by interfering with the nervous system of heartworm larvae, preventing them from maturing into adults..

Pyrantel pamoate acts against roundworms and hookworms by paralyzing their muscles, allowing them to be expelled from the body through bowel movements. Heartgard Plus is a chewable tablet and is administered orally to dogs monthly.
