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.
Rupatadine belongs to the class of medications called second-generation antihistamines, specifically the class known as histamine receptor antagonists. It works by blocking the action of one of the body's natural chemicals known as histamine. Histamine is responsible for many of the symptoms caused by allergies. Rupatadine is used for the relief of symptoms associated with seasonal and year-round allergies, including sneezing, itchy and runny nose, and tearing and redness of the eyes. It is also used for the relief of symptoms associated with allergic skin conditions, including chronic hives, itching, and other skin disorders. Rupatadine usually starts working within 2 hours and lasts for 24 hours.
The recommended dose of rupatadine for adults and adolescents 12 years of age and older is 10 mg taken by mouth once daily. The dose for children 2 to 11 years old is based on body weight. Children weighing 10 kg to 25 kg should be given 2.5 mg (2.5 mL) taken by mouth once daily. Children weighing more than 25 kg should take 5 mg (5 mL) by mouth once daily. Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons. Wash the syringe after each use. This medication may be taken with food or on an empty stomach. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications.
