Injection Tips
Giving an injection is simple, but it does take practice. Patients may be frustrated in the beginning. Here are some basic tips you can give patients:- Make sure it's the right insulin and dose at the right time
- Check the expiration date on the insulin
- If the patient is using "cloudy" insulin, gently mix it well before using
- Clean the top of the insulin cartridge or vial with an alcohol swab each time
- Make sure the injection site is clean
- Go through the skin quickly to minimize any discomfort
- Go straight in through the skin, not at an angle
- People who are very thin may use short needles to allow them to go straight in without going too deep
Injection site: selection and rotation
Insulin is generally injected into the subcutaneous fat around the abdomen, buttocks, legs, or on the back of the arms. The chart below shows where patients typically inject insulin.
For insulin to work best, it's important to use a different location for each injection. This is called site rotation, and involves following a regular pattern as patients move from site to site. If the patient takes more than one injection each day, advise him or her to use a different area for each injection. Different people use different patterns, but the intent should always be to use all of the areas and the sites. When patients do this, no one site will be used too often. Overusing a site can cause tissue changes that lower or change insulin absorption. For additional information relevant to injecting insulin, please see the vial and syringe instructions on the patient website.
Needles after use
Most states require that patients store used needles in a hard container. Empty coffee cans are good examples. Patients can also buy "sharps containers" at most pharmacies. Check with your local health department to confirm the rules where you practice.
Important Safety Information
Humalog insulins are contraindicated during episodes of hypoglycemia and in patients sensitive to Humalog or one of its excipients. The safety and effectiveness of Humalog in patients less than 3 years of age have not been established. Safety and effectiveness of Humalog Mix75/25 and Humalog Mix50/50 in patients less than 18 years of age have not been established. There are no adequate and well-controlled clinical studies of the use of Humalog in pregnant or nursing mothers.
Potential side effects associated with the use of all insulins include hypoglycemia, weight gain, hypokalemia, lipodystrophy, and hypersensitivity. Because of the difference in action of Humalog, care should be taken in patients in whom these conditions may be clinically relevant (e.g., those who are fasting, have autonomic neuropathy or renal impairment, are using potassium-lowering drugs, or taking drugs sensitive to serum potassium level). Patients should be advised not to mix Humalog Mix75/25 or Humalog Mix50/50 with another insulin. Starting or changing insulin therapy should be done cautiously and only under medical supervision.
When used in an external insulin pump, Humalog should not be diluted or mixed with any other insulin. Humalog Mix75/25 and Humalog Mix50/50 are not indicated for use in external insulin pumps.
Humalog differs from regular human insulin by its rapid onset of action, as well as a shorter duration of activity. Therefore, Humalog and Humalog Mixtures should be given within 15 minutes before a meal. Humalog can also be given immediately after a meal. The short duration of action of Humalog means that patients such as those with type 1 diabetes, whose basal insulin levels are inadequate, will also require a longer-acting insulin to give optimal glucose control (except when using an insulin pump).
Clinical studies comparing Humalog Mix75/25 with human insulin mixtures did not show a difference in the overall rate of hypoglycemia between the two treatments. The overall rate of hypoglycemia did not differ between type 1 and type 2 patients treated with Humalog, as compared with regular human insulin. The lower rate of hypoglycemia with Humalog may be related to higher nocturnal blood glucose levels, as reflected by a small increase in the mean fasting blood glucose levels.
The clinical significance of improvement in postmeal hyperglycemia has not been established. In 12-month clinical studies, A1C did not differ between patients treated with regular human insulin and those treated with Humalog.
Humalog, Humalog Mix75/25, and Humalog Mix50/50 are available by prescription only.
