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.
If you suffer from irritated, watery, itchy eyes, you may have a condition called allergic conjunctivitis. The clear, thin layer covering your eyeball and inside your eyelid is called the conjunctiva. Sometimes this layer becomes irritated and leads to a condition that doctors call conjunctivitis. If the irritation is caused by allergens (like pollen, pets, or dust) that get into your eye, it's allergic conjunctivitis. Allergic conjunctivitis is a real problem for many people. The American Academy of Allergy, Asthma and Immunology states that almost 1 out of 4 people in the US have the condition.1 Discovering more about what causes allergic conjunctivitis and how OPTIVAR eye drops can relieve the itch of allergy eyes may be the first step to feeling better.
