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.

    What is Zaditor used for?

    Zaditor Asthma Medication

    Zaditor (Ketotifen)

    Ketotifen is the main ingredient found in this particular medicine, and this main ingredient basically has two main functions. Firstly, Ketotifen is an antihistamine agent as it blocks histamine from causing allergic reactions in the eye. Histamine is a natural substance that is known to cause allergic reactions. Secondly, this main ingredient also acts as a cell stabilizer that lowers the release of natural substances in our body that may lead to us developing an allergic reaction.

    Ketotifen eye drops are primarily used to stop our eyes from itching and watering as a result of an allergic reaction. This allergic reaction may be seasonal one or some people just develop an eye allergy due to any reason.

    Zaditor allergy eye drops can be ordered online from Canada Pharmacy. It is a fast and efficient way to get your medicine delivered to your doorstep.


    Zaditor can also be purchased without a written prescription from your doctor. If you opt for this method of getting this medicine, ensure that you read all the instructions on the leaflet provided with the medicine, so you take the correct dosage.

    Wash your hands thoroughly and then use the eye drops. Be careful that the eye drop dropper does not touch your hand or your eyelid to avoid contaminating it.

    Bend your head a little backward and make a pouch by pulling out your lower eyelid gently with your finger. Put one drop in the infected eye and close your eye for two minutes. Gently massage the area to dissolve the medicine. Repeat the same in the other eye if that too is infected.

    Consult your doctor if you can wear lenses while using Zaditor. If yes, remove them prior to applying the eye drops and then wear them 10 minutes after using Zaditor.


    The active ingredient in this medicine is Ketotifen.
