hylan G-F 20
Hylan G-F 20 belongs to the group of medications known as synovial fluid replacements. It is used to relieve the symptoms of osteoarthritis (a condition causing joint "wear and tear" and pain) in the hip, ankle, shoulder, and knee joints. It works by mimicking the body's own synovial fluid (a fluid that lubricates and cushions the joints). Relief from pain can last up to 6 to 12 months.
Your doctor may have suggested this medication for conditions other than the ones listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
Each mL of sterile, nonpyrogenic, elastoviscous fluid contains hylan 8 mg. Nonmedicinal ingredients: disodium hydrogen phosphate, sodium chloride, sodium dihydrogen phosphate hydrate, and sterile water for injection.
This medication is injected into the joint that is affected by osteoarthritis. Your doctor or a trained health care professional will give you the injection, usually at a clinic. The dose depends on the location of the arthritis.
For osteoarthritis of the hip, ankle, or shoulder, the usual dose is a single injection into the affected joint. This dose can be repeated after 1 to 3 months if the first dose doesn't provide enough relief.
For osteoarthritis of the knee, the usual dose is 1 injection per week into the knee joint for a total of 3 weeks. If this first set of injections doesn't provide enough relief, a second set of 3 weekly injections can be given, provided at least 4 weeks have passed since the last treatment. The maximum recommended dose is 6 injections within 6 months.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are receiving the medication without consulting your doctor.
