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.
Serevent Diskus contains the medication salmeterol, which is a long-acting beta-agonist (LABA). The medication comes in a dry powder inside capsules made for inhalation. The inhaler device has a mechanism to puncture each capsule to prepare the powder for inhalation.
People with diseases of the airway have trouble breathing because the muscles in the lung may contract (tighten) more often or more tightly than needed. This contraction makes the airways smaller. Serevent Diskus works by binding to beta-2 receptors on the surface of lung muscle cells. By attaching to these receptors, Serevent Diskus relaxed the muscles, making it easier to breathe.
Once you are prescribed and buy Serevent Diskus, then inhale the contents of 1 capsule twice daily.
How to use Serevent Diskus: Do not exhale into the device, as it may blow out the contents of the capsule. Use the Serevent Diskus in a level and flat position. Inhale quickly and deeply and hold the breath for 10 seconds or if it is comfortable.
The active ingredient in Serevent Diskus is salmeterol.
Serevent Diskus and other LABA medications may increase the risk of asthma-related death when used alone to treat asthma. When treating asthma, LABA should be combined with an inhaled corticosteroid (ICS).
Serevent Diskus is not a rescue inhaler and should not be used for acute bronchospasm. If you are having trouble breathing from bronchospasm, do not use Serevent Diskus for rescue, and use a rescue inhaler like albuterol instead.
Some people have reported symptoms in their upper airway like a spasm, swelling, and choking when using Serevent Diskus.
Some common side effects of Serevent Diskus may include:
Not everyone experiences side effects while taking Serevent Diskus, but these are some of the most common. Speak with your doctor or pharmacist for a full list of side effects that are most likely to affect you.
