Frequently Asked Questions

Commonly asked questions about joint pain and joint injections.

A synovial joint is one in which the ends of the bones are enclosed in a capsule containing a thick, slippery liquid called synovial fluid.

For more information, please go to our "What is a Synovial Joint" page.

OSTENIL® has to be administered by a suitably qualified clinician. This might be your GP, a Consultant, or a qualified Physiotherapist or Podiatrist. They will usually order it on your behalf. Alternatively, you can obtain a prescription and take this to your local pharmacy where it can be ordered for you. You will then have to take the syringes back to the clinician for injection into the affected joint. For more information, please go to our "FAQ How to get Ostenil" page.

No one knows your particular condition better than your GP or consultant, so please ask him or her. TRB Chemedica is not qualified to give medical advice.

Yes, they are. Please ask your GP for more details.

OSTENIL® does not contain any animal proteins, so it is fine to be used for vegetarians.

All OSTENIL® products are licensed for use in any synovial joint of the body, typically the knee, hip, or shoulder joints. Ostenil® products are also suitable for the elbow, ankle, and some of the small joints such as the jaw, hand (finger, wrist and saddle joints) and toe joints.

You may not notice any benefits immediately after the first injection, but you should gradually start to feel less pain and stiffness over the next few weeks.

The improvement in your symptoms should last for several months, depending partly on the number of injections you have. You can expect the benefit from three injections to persist for up to 9 months.

After your injection with OSTENIL® hyaluronic acid (or: sodium hyaluronate) into your knee joint, or other synovial joint, you may want to utilise and prolong the positive effects of the treatment and get your joints moving again.
Please ask your GP, Physiotherapist, or Orthopaedic Consultant for more detailed advice.
