Protaphane: How to use this insulin: Protaphane is administered by injection under the skin (subcutaneously). Never inject your insulin directly into a vein or muscle. Always vary the sites you inject within the same region, to reduce the risk of developing lumps or skin pitting. The best places to give yourself an injection are: your buttocks; the front of your thighs or upper arms.
How to inject Protaphane on its own or to mix with fast-acting insulin: Make sure you have the correct syringe with the corresponding unit scale for insulin injections.
Draw air into the syringe in the same amount as the dose of insulin you need.
Follow the instructions given by your doctor or nurse.
Just before injecting this insulin, roll the vial between your hands until the liquid is uniformly white and cloudy. Resuspending is easier if the insulin has reached room temperature.
Inject the insulin under the skin. Use the injection technique advised by your doctor or nurse.
Keep the needle under your skin for at least 6 seconds to make sure that the full dose has been delivered.
