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.


Guaifenesin is a prescription expectorant medication used to provide cough relief for pet plus clearing mucus in their airway. It is also called Mucinex for pets and common OTC cough medications like Robitussin have the same combination of guaifenesin and dextromethorphan as active ingredients. The size of your pet will determine the correct guaifenesin dosage and this pet cough suppressant is good for helping a dog or cat clear their throat of phlegm or mucus buildup. Guaifenesin is also prescribed to treat kennel cough for dogs.

You can buy guaifenesin with a prescription, and your best price on it will be when you order pet medication online from Canada Drugs Direct.


Standard guaifenesin dosage is 1 10mg tablet once per day, but smaller dogs may take half a 10mg tablet a day. The medication dosage for your pet will be indicated in your prescription.

Side Effects
