Read the entire label carefully before starting to use this medication, as it contains important information for you.
Humalog Mix25 KwikPen is used to treat diabetes. It is a pre-mixed suspension. Its active ingredient is insulin lispro. In Humalog Mix25 KwikPen, 25% of insulin lispro has been dissolved in water and works faster than normal human insulin because the insulin molecule has been slightly changed. In Humalog Mix25 KwikPen, a suspension of 75% of insulin lispro has been incorporated along with protamine sulfate, to prolong its action.
You have diabetes when your pancreas does not produce enough insulin to control your blood glucose level. Humalog Mix25 is a substitute for your own insulin and is used to control glucose levels in the long term. It acts very quickly and for a longer time than soluble insulin.
Humalog Mix25 is usually used within 15 minutes of eating.
Your doctor may recommend using Humalog Mix25 KwikPen in addition to a longer-acting insulin. Each one comes with its own leaflet with specific information. Do not change your insulin unless your doctor tells you to. Be very careful when changing insulin.
The KwikPen is a disposable pre-filled pen that contains 3 ml (300 units, 100 units/ml) of insulin lispro. A KwikPen contains multiple doses of insulin. The KwikPen marks 1 unit each time.
The number of units is shown in the dosing window, check it always before your injection.You can inject from 1 to 60 units in a single injection.If your dose is more than 60 units, you will need to administer more than one injection.
Do not use Humalog Mix25 KwikPen

The amount of insulin you need generally decreases during the first three months of pregnancy and increases during the next six months. If you are breastfeeding, you may need to adjust your insulin dose or diet.

If you use more Humalog Mix25 than you need or are unsure of how much you have injected, you may have low blood sugar. Check your blood sugar.
If your blood sugar is low (mild hypoglycemia), take glucose tablets, sugar, or a sweet drink. Then eat fruit, cookies, or a snack, as your doctor has instructed you, and rest afterwards. This usually helps you recover from mild hypoglycemia or a small overdose of insulin. If you get worse and your breathing is shallow and your skin is pale, call your doctor immediately. Severe hypoglycemia can be treated with a glucagon injection. After the glucagon injection, take glucose or sugar. If you do not respond to glucagon, you should go to the hospital. Ask your doctor to inform you about glucagon.
If you use less Humalog Mix25 than you need or are unsure of how much you have injected, you may have high blood sugar. Check your blood sugar.
If not treated properly, hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar) can be very serious and cause headaches, nausea, vomiting, dehydration, loss of consciousness, coma, and even death (see A and B in section 4 "Possible side effects").
