Hyaluronan precautions. Do not strain your knee joint for two days after receiving this medicine. Avoid activities such as jogging, soccer, tennis, heavy lifting, or standing on your feet for a long time. Temporary pain or swelling in the knee joint may occur after receiving hyaluronic acid injection. Call your doctor if the pain or swelling in the knee persists or becomes worse after receiving this medicine. Do not use this medicine with disinfectants containing quaternary ammonium salts (e.g., benzalkonium chloride). This may prevent hyaluronic acid injection from working properly.
