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.

  • Product Details


    Ragwitek (short ragweed pollen allergen extract) is a sublingual immunotherapy medication used to treat ragweed pollen allergies. Exposing the immune system to small doses of the allergen may help build tolerance and reduce allergy symptoms, such as sneezing, runny or stuffy nose, and itchy, watery eyes. The treatment is checked by a skin or lab test for certain allergy-causing substances and can be prescribed for people with allergic rhinitis, with or without eye allergies.


    The usual dosage of Ragwitek is one sublingual tablet daily. Place the tablet immediately under the tongue and allow it to dissolve completely. It is important not to swallow for at least 1 minute, as the medicine needs time to be absorbed. Follow your healthcare provider's instructions for the specific dosage and administration schedule.

    Treatment is usually started at least 12 weeks before the start of ragweed pollen season. The first dose of Ragwitek should be administered in an office setting where a healthcare provider can monitor for any adverse reactions for at least 30 minutes.


    Ragwitek is a medication that contains a short ragweed pollen allergen extract, which comes from the Ambrosia artemisiifolia plant.


    Avoid taking or using Ragwitek if any of the following apply:

    • Severe, unstable or uncontrolled asthma
    • History of life-threatening allergic reactions, such as anaphylaxis, to allergen immunotherapy
    • History of eosinophilic esophagitis
    • Known or suspected allergy to any ingredients in the medication


    • Before you start taking Ragwitek (ragweed pollen allergen extract), discuss the following with a healthcare provider:

    • This treatment may cause severe allergic reactions that can be life-threatening. Monitor for any signs of an allergic reaction, such as hives, itching, trouble breathing, or swelling of the face or throat.
    • If you have any wounds or inflammation inside the mouth, temporarily discontinue the medication until the skin condition resolves.

    Side Effects

    Ragwitek may cause side effects in some users. Common side effects include itching of the mouth, lips, or tongue, swelling under the tongue, and throat irritation. These side effects, by themselves, are generally not dangerous or life-threatening.

    However, Ragwitek can also cause serious side effects that require immediate medical attention. These may include severe dizziness, fast heart rate, cough, chest tightness, wheezing, trouble breathing, hives, itching, flushing, and swelling of the face, lips, tongue, or throat. If any of these severe side effects arise, seek medical help right away.
