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.
Levitra is a prescription medication used to treat erectile dysfunction. Erectile dysfunction (ED) is a condition where a person is unable to get or maintain an erection for sexual intercourse. ED can be caused by physical, mental, or other medical conditions.
Levitra works by relaxing blood vessels that fill the corpus cavernosum of the penis. Sexual stimulation is required for Levitra to be effective, and it will not work on its own.
The starting Levitra dosage is 10 mg by mouth as needed, about 60 minutes before sexual activity. The dose may be decreased to 5 mg or increased to 20 mg.
Do not take more than one tablet of Levitra per day unless directed by your healthcare provider.
If you have liver dysfunction, you may need to reduce the starting dose to 5 mg.
The active ingredient in Levitra is Vardenafil, which is also the name for Levitra generic.
Levitra has many potential drug-drug interactions with other medications. Tell your doctor and pharmacist about all other medications you are taking, including:
Tell your doctor if you have a history of heart problems.
If you have an erection lasting longer than four hours, especially if it is painful, then seek immediate medical attention.
