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.
Gelsyn-3 is similar to the fluid that surrounds the joints in your body. This fluid acts as a lubricant and shock absorber for the joints. Gelsyn-3 is used to treat knee pain caused by osteoarthritis. Gelsyn-3 is usually given when other arthritis medications have not been effective. Gelsyn-3 may also be used for purposes not listed in this medication guide.
Gelsyn-3 is injected directly into your knee joint. A healthcare provider will give you this injection. Gelsyn-3 is usually given once every week for 3 to 5 weeks. Follow your doctor's dosing instructions very carefully. To prevent pain and swelling, your doctor may recommend resting your knee or applying ice for a short time after your injection. Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions. Tell your doctor if your symptoms do not improve, or if they get worse.
