Ostenil Mini Pack Shot

Instructions for Use 


Sodium hyaluronate 1.0 %. Viscoelastic solution for injection into small joint for improvement of mobility and pain relief in osteoarthritis. Transparent solution of natural, highly purified sodium hyaluronate obtained by fermentation. Devoid of animal proteins. Sterile by moist heat. The content and the outer surface of the OSTENIL® MINI pre-filled syringe are sterile if the sterile barrier is intact. For single use only.


1 pre-filled syringe of 10 mg/1.0 ml OSTENIL® MINI in a sterile pack. Needle not included.


1 ml isotonic solution (pH 7) contains 10.0 mg sodium hyaluronate, sodium chloride, disodium phosphate, sodium dihydrogen phosphate and water for injections.


Pain and restricted mobility in degenerative and traumatic changes of small synovial joints, for example, the facet  joints of the lumbar spine, the saddle joint of the thumb, the proximal joint of the big toe and the temporomandibular joint.


OSTENIL® MINI should not be used in patients with ascertained hypersensitivity to any of its constituents.


The treatment with OSTENIL® MINI is not recommended in children, pregnant and lactating women or in inflammatory joint diseases such as rheumatoid arthritis or Bechterew disease. In case of joint effusion, the effusion should be reduced first.
The national guidelines for intra-articular injections must be observed, this includes thorough disinfection of the injection site and other measures to avoid joint infections. OSTENIL® MINI should be injected accurately into the joint cavity, if necessary, under imaging control. Avoid injections into blood vessels or surrounding tissues.
Do not use if the pre-filled syringe or sterile pack are damaged. Any solution not used immediately after opening must be discarded. Otherwise, the sterility is no longer guaranteed, and this may be associated with a risk of infection. Do not resterilize as this may damage the product. No information on the impairment of any diagnostic investigations, such as magnetic resonance imaging, clinical condition assessments or therapeutic treatments by OSTENIL® MINI have been notified yet.


No information on the incompatibility of OSTENIL® MINI with other medical devices and drugs for intra-articular use or oral analgesic or anti-inflammatory drugs have been notified yet.


In very rare cases (less than 1 in 10,000 patients) local secondary phenomena such as pain, feeling of heat, redness, swelling/joint effusion and tachycardia may occur during or after the injection of OSTENIL® MINI. As with all invasive joint treatments, in very rare cases an infection may occur. Before injecting OSTENIL® MINI, the patient should be informed about contraindications and undesirable effects.


Any serious incident that has occurred in relation to the device should be reported to the manufacturer TRB Chemedica AG and the local competent authority of the user.


Inject OSTENIL® MINI into the affected joint once a week for a total of 1 – 3 injections. Several joints may be treated at the same time. Depending on the severity of the joint disease the beneficial effects of a treatment cycle of three intra-articular injections may last for six months or longer. The sodium hyaluronate itself is degraded within a few days. Repeat treatment cycles may be administered as required. Take the pre-filled syringe out of the sterile pack, unscrew the Luer lock cap from the syringe, attach a suitable needle with Luer connector (for example 18 to 25 G) and secure it by turning slightly. Remove any air bubble, if present, before injection.


Put the used syringe in a sharps disposal container right away after use. Do not throw away the OSTENIL® MINI prefilled syringe in the household trash. Follow your community guidelines for the right way to dispose of your sharps disposal container.


Synovial fluid, which is viscoelastic due to the presence of hyaluronic acid, is found in all synovial joints, where it ensures normal, painless movement due to its lubricating and shock-absorbing properties. In degenerative joint disorders such as osteoarthritis, the viscoelasticity of the synovial fluid is markedly reduced thereby decreasing its lubricating and shock-absorbing functions. This increases mechanical loading of the joint and cartilage destruction which ultimately results in pain and restricted mobility of the affected joint. Supplementing this synovial fluid with intraarticular injections of highly purified hyaluronic acid can ameliorate the viscoelastic properties of synovial fluid. This improves its lubricating and shock-absorbing functions and reduces mechanical overload of the joint. Clinical trials showed a pain decrease and improvement in joint mobility up to six months.


Store between 2 °C and 25 °C in a dry place, protected from light! Do not use after the expiry date indicated on the box. Keep out of the reach of children.
