Actrapid is a fast-acting insulin. This means that it will start to lower your blood sugar about half an hour after you take it, and the effect will last for approximately 8 hours. Actrapid is often given in combination with longer-acting insulin products.
How to use this insulin
Actrapid is for injection under the skin (subcutaneously). Always vary the sites you inject, to avoid lumps (see 5 Possible side effects). The best places to give yourself an injection are: the front of your waist (abdomen); your buttocks; the front of your thighs or upper arms. Your insulin will work more quickly if you inject it around the waist.
