1. Get everything you need: insulin bottle, syringe, alcohol wipe, and your daily record log to write down the dose. (A log book is included with your blood glucose meter.)
2. Wash your hands with soap and water.
3. Write down the dose of insulin in your daily record.
4. Check the insulin. First, make sure you've got the right bottle (the right type of insulin). Second, check the insulin for any discoloration, cloudiness, or sediment (stuff sitting on the bottom or floating around inside). If you see any of these, throw the insulin away and use new insulin.
5. Wipe the top of the bottle with an alcohol wipe.
6. Pull back the plunger on the syringe to draw in enough air to equal your insulin dose (use the lines and numbers on the barrel of the syringe), then push the needle into the bottle and inject the air into the bottle. (This prevents the vacuum inside the bottle from sucking the insulin back out of the syringe.)
7. With the needle in the bottle, turn the bottle and syringe upside down. First draw up insulin past your correct dose. Then, slowly push on the plunger to the line of your correct dose of insulin.
8. Before withdrawing the needle from the bottle, check for air bubbles. If you notice any, tap the syringe so that the bubbles float to the top. Pull the plunger past your dose again and slowly push in the plunger until all bubbles are gone. Repeat as needed to get rid of air bubbles, then withdraw the needle from the bottle.
9. If the insulin has been stored in the refrigerator, warm the syringe by holding it in your closed hand for a minute or so. Injections hurt less if the insulin is warm.
