- Check your insulin's expiration date. If you have not finished it before it expires, throw the rest away.
- Store unopened bottles of insulin in the refrigerator. Do not store your insulin at extreme temperatures.
- Keep the bottle of insulin you are using at room temperature. Injecting cold insulin can sometimes make the injection more painful. (Most doctors believe that insulin kept at room temperature will last 1 month. Check with the information on your glucose to make sure.)
- If your treatment requires that two different insulins be mixed, be sure that you understand which of the two should be drawn into the syringe first. If you change the mixing pattern, you may change the dose you receive. Some insulins cannot be mixed together. Do not mix insulins together in one syringe unless you have been instructed to do so.
