Contents of the pack
Humalog KwikPen is used to treat diabetes. It works more quickly than normal human insulin because the insulin molecule has been changed slightly.
You have diabetes if your pancreas does not make enough insulin to control the level of glucose in your blood. Humalog is a substitute for your own insulin and is used to control glucose levels in the long term. It acts quickly and has a shorter duration of action (2 to 5 hours) compared to soluble insulin. Normally, Humalog is used within 15 minutes of a meal.
Your doctor may tell you to use Humalog KwikPen as well as a longer-acting insulin. Each of these insulins has its own patient information leaflet to tell you how to use them. Do not change your insulin unless your doctor has told you to. Be very careful if you do change your insulin.
Humalog can be used in adults and children.
The KwikPen is a pre-filled pen that contains 3 ml (300 units, 100 units/ml) of insulin lispro. One KwikPen contains multiple doses of insulin. The KwikPen measures each dose of insulin in units. The number of units is shown in the dose window, always check this before you inject.You can give yourself one dose of 1 to 60 units of insulin at a time. If your dose is more than 60 units, you will need to give yourself more than one injection.
Do not use Humalog KwikPen
Warnings and precautions
Tell your doctor as soon as possible if you experience signs of heart failure such as difficulty breathing, rapid weight gain or localised swelling (oedema).
Skin changes at the injection site
You should rotate your injection sites to avoid getting lumps under the skin. Insulin may not work properly if you inject it into a lumpy area (see How to use Humalog KwikPen). If you are currently injecting in a lumpy area, talk to your doctor before you start injecting in a different area. Your doctor may tell you to check your blood sugar levels more often and to adjust your insulin dose or the dose of your other diabetes medications.
