Hyalgan® is not a drug. Its principal component is a naturally derived substance called Hyaluronan that relieves pain by lubricating and cushioning your knee joint. Hyaluronan is a natural chemical found in the body and is present in a particularly high amount in joint tissues and in the fluid that fills the joint (also called synovial fluid). Hyalgan® is injected directly into the knee.
Hyalgan® injections work differently than oral pain medications. Hyalgan® does not pass through your blooedstream to work. Because Hyalgan® is injected directly into your knee, it does not cause stomach bleeding problems like some pain medications.
Hyalgan® can provide long-lasting pain relief for up to 6 months and be safely used for up to 30months.
