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

    Description

    Dihydroergotamine Mesylate is often prescribed for the treatment of migraines and headaches when other forms of treatment have not been successful. It is inhaled through the nostrils to provide quick relief of headaches as they start.

    Dihydroergotamine Mesylate works by tightening the blood vessels in the brain, which leads to a decrease in pain signals. If blood vessels are too relaxed, this can push into the surrounding tissue and cause inflammation that leads to headaches.

    Directions

    The standard dosage is to inhale one inhalation through the nose at the onset of symptoms. Repeat every hour as needed, do not exceed 3 mg per 24 hour period. Do not exceed 6 mg in a week.

    Taking more than the recommended maximum can lead to rebound headache and worsening of pain and other symptoms.
