How do I take hyaluronan injections and how long do they take to work?
How often you have the injections depends on the type of hyaluronan preparation used. You’ll probably be given a course of 3–5 injections, each separated by 1–3 weeks. Some doctors give the first two injections close together and then extend the period between those remaining. You probably won’t need to rest the joint after the injections.
The injections should work within days if they’re effective and they’ll probably last for a few months. Sometimes your doctor may recommend you have repeat courses.
The particles in hyaluronan are quite large, so they’ll stay in your joint for some time before they’re absorbed into your blood stream. Some of the hyaluronan preparations available contain significantly larger particles than others and this can influence your doctor's choice.
