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.

    betahistine tablets

    SERC (betahistine) is a medication that can treat episodes of recurrent vertigo that are associated with Ménière’s disease.

    People with Ménière’s disease have extra fluid that builds inside of their ear canals. Extra fluid interferes with the nerves in the inner ear that detect position, movement, and balance. People with Ménière’s disease have recurrent episodes of vertigo that may interfere with their daily lives.

    SERC medication works by interacting with both histamine-1 and histamine-3 receptors on the surface of nerve cells of the ear. The interactions seem to decrease how much histamine is available to activate these nerve cells. SERC also increases blood flow to the inner ear and it slows down nerve signals in lateral and medial vestibular nuclei.

    The FDA has not approved SERC for any indication in the United States. SERC is widely used in both Europe and Canada.


    Take 24 mg to 48 mg by mouth in divided doses. SERC dosages include a 16 mg tablet and a 24 mg tablet.

    Examples of different dosing may include:

    • Twice daily dosing: 24 mg by mouth twice daily
    • Three times daily dosing: 8 mg to 16 mg by mouth three times daily


    The active ingredient in SERC is betahistine.
