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.


SERC (betahistine) is a medication used to treat episodes of recurrent vertigo in patients with Ménière’s disease. People with Ménière’s disease have excess fluid buildup in the structures of their inner ear. Excess fluid can interfere with the nerve signals sent by inner ear structures to the brain that help a person detect balance, movement, and position. Episodes of vertigo are characterized by feelings of dizziness and spinning. Other symptoms of Ménière’s disease include tinnitus, hearing loss, and a feeling of pressure in the ears. SERC (betahistine) works by blocking histamine-3 receptors on the surface of auditory neurons. It also partially agonizes histamine-1 receptors. These mechanisms appear to increase blood flow to cochlear regions of the ear. Betahistine is not currently approved by the FDA for any indication in the United States. Betahistine is widely used and available for use in Europe and Canada.


The usual dosage of betahistine is 24 mg to 48 mg by mouth in divided daily doses. Follow the packaging instructions when using this medication.


The active ingredient in SERC is betahistine.


SERC (betahistine) is contraindicated in patients with pheochromocytoma.

Patients with a history of peptic ulcers should speak with their doctor before taking SERC (betahistine).

Patients with a history of asthma should speak with their doctor before taking SERC (betahistine).

Side Effects

Adverse effects of SERC (betahistine) may include:

  • Bloating
  • Headache
  • Itching
  • Nausea and vomiting
  • Skin rashes
  • Stomach pain

This is not a complete list of side effects. Speak with your doctor or pharmacist before starting any non-prescription medication.
