Humalog KwikPen – Insulin lispro uses, dose and side effects


100 units/ml solution for injection in a pre-filled pen
insulin lispro

1. What Humalog KwikPen is and what it is used for

Humalog KwikPen is used to treat diabetes. It acts faster than normal human insulin because the insulin molecule has changed slightly.

You get diabetes if your pancreas does not produce enough insulin. Humalog replaces your insulin and is used to control blood glucose levels for a longer period. It works very quickly and for a shorter time than soluble insulin (2-5 hours). You should normally take Humalog within 15 minutes before or after a meal.

Your doctor will tell you if you should use Humalog KwikPen with longer-acting human insulin. Each type of insulin has its user information. Do not change your insulin unless your doctor tells you to. Be very careful if you change your insulin.

Humalog can be given to both children and adults. KwikPen is a single-use pre-filled pen containing 3 ml (300 units, 100 units/ml) of insulin lispro. Each KwikPen contains several doses of insulin. With KwikPen you can set 1 unit at a time. The number of units is displayed in the dosing window, always check there before injecting. You can give from 1-60 units in one injection. If your dose is over 60 units, you will need to give another injection.

2. What you need to know before using Humalog KwikPen

DO NOT use Humalog KwikPen

  • if you think that a so-called insulin sensation (low blood sugar) begins. Later in this user information, there are instructions on how to deal with a mild insulin sensation (see section 3: If you have used more Humalog than you should).
  • if you are allergic to insulin lispro or any of the other ingredients of this medicine (listed in section 6).

Warnings and cautions

  • Always check the packaging and the pre-filled pen label so that the name and type of insulin match when you get it from the pharmacy. Make sure you get the Humalog KwikPen prescribed by your doctor.
  • If your blood sugar is under good control of your current insulin , you may not be able to detect the warning signs when your blood sugar gets too low. Warning signals are listed later in this user information. You should carefully keep track of when you should eat, how often you should exercise and how much you should work. You should also carefully check your blood sugar level by testing your blood sugar frequently.
  • Some people who have had insulin sensations after switching from animal insulin to human insulin have reported that the early warning symptoms were less clear or different. If you often have insulin sensations or have difficulty recognizing them, talk to your doctor.
  • If you answer YES to any of the following questions, talk to your doctor, pharmacist or diabetes nurse.
    • Have you recently become ill?
    • Do you have problems with your liver or kidneys?
    • Do you train more than usual?
  • The amount of insulin you need may change with alcohol intake.
  • You should also talk to your doctor, pharmacist or diabetes nurse if you plan to travel abroad. The time difference between countries may mean that you have to take your injections and eat at other times than when you are at home.
  • Some patients who have had type 2 diabetes mellitus and heart disease for many years or earlier stroke , developed heart failure during treatment with pioglitazone and insulin . Tell your doctor as soon as possible if you get signs of heart failure such as unexpected shortness of breath, rapid weight gain or local swelling ( edema ).
  • This pen is not recommended for blind or partially sighted people unless they are assisted by someone who has been trained to use the pen.

Skin changes at the injection site

To prevent skin changes, e.g. nodules under the skin, you should constantly change the injection site. It may be that insulin et not work as well if you inject in an area of nodules (see “How to use Humalog KwikPen). Contact your doctor before changing the injection site if you are currently injecting in an area with lumps. Your doctor may advise you to check your blood sugar more often and to adjust your insulin dose or the dose of other diabetes medicines.

3. How to use Humalog KwikPen

Always use Humalog KwikPen exactly as your doctor has told you. Consult a doctor if you are unsure. To prevent the transmission of diseases, the pen should only be used by you, even if the needle is replaced.


  • You should normally inject Humalog within 15 minutes before a meal. If you need to, you can inject shortly after the meal. Dose one is determined by your doctor who adjusts it individually for you. These instructions are personal and just for you. Follow them closely and visit your diabetes clinic regularly.
  • If you change the type of insulin (eg from animal insulin or other human insulin to a Humalog product) you may need to take more or less than before. This may appear at the first injection one or it may be a gradual change over several weeks or months.
  • Humalog KwikPen is only suitable for injection under the skin. Talk to your doctor if you need to inject insulin in any other way.

Preparation of Humalog KwikPen

  • Humalog is already dissolved in water so you do not need to mix it. You may only use it if it looks like water. The solution should be clear, colorless and free of solid particles. Check this before each injection .

Preparation of the pen (see instructions for use)

  • Wash your hands.
  • Read the instructions for use that describe how to use the pre-filled insulin pen. Follow the instructions carefully. Consider the following:
  • Use a clean needle (needles are not included in the package).
  • Check the insulin flow (remove air bubbles) before each injection . There may still be small air bubbles left in the pen. These are harmless but if the air bubbles are too large they can affect the insulin dose.

Injection with Humalog

  • Wash the injection site as instructed. Inject under the skin ( subcutaneously ) as shown. Do not inject directly into a blood vessel. Wait 5 seconds after finishing the injection before pulling out the needle, then you are sure that you have received the full dose one. Do not massage the injection site. Make sure that you have at least a 1 cm margin to the previous injection site and that you change the injection site that you have been assigned. Humalog injection works faster than short-acting (regular) insulin regardless of the injection site (upper arm, thigh, buttocks or abdomen).
  • You should not inject Humalog intravenously . Inject Humalog exactly as your doctor or diabetes nurse has told you. Only your doctor can give Humalog intravenously . He does this only in special circumstances such as surgery or if you are ill and your blood sugar levels are too high.

After injection

  • Unscrew the needle using the outer needle cap immediately after injection . In this way, the solution remains sterile and leakage is prevented. It also prevents air from entering the pen and clogging the needle. Never share needles or pens with anyone else. Put the protective cap on the pen.

Additional injection er

  • Each time you use the pen, you must use a new needle. Remove air bubbles before each injection . You can see how much insulin is left by holding the pen so that the needle is pointing upwards. The scale on ampoule one shows approximately how many units are left.
  • Never mix other insulin in your disposable pen. When the pen is empty, it should not be used again. Throw it away safely. Pharmacy staff or your diabetes nurse can tell you how.

How to use Humalog in an infusion pump

  • KwikPen is only suitable for injection under the skin. Do not use the pen to give Humalog in any other way. There are other forms of Humalog 100 Units / ml available if needed. Talk to your doctor if it is relevant to you.

If you use more Humalog than you should

You may get low blood sugar if you have used too much Humalog or are unsure about how much you have injected. Check your blood sugar.

If your blood sugar is low ( weak insulin sensitivity ), take glucose tablets, sugar, or a sweet drink. Then take fruit, biscuits, or a sandwich according to your doctor’s instructions and rest for a while. Often, a weak insulin sensation or a slight overdose of insulin disappears with this treatment. If you get worse, have shortness of breath, and turn pale, contact your doctor immediately. Quite severe hypoglycaemia can be treated with a glucagon injection. Eat glucose or sugar after the glucagon injection. If you are not improved by glucagon, you should be treated in a hospital. Ask your doctor to tell you about glucagon.

If you forget to use Humalog

You may get high blood sugar if you have used too little Humalog or are unsure about how much you have injected. Check your blood sugar.

Failure to treat hypoglycaemia (low blood sugar) or hyperglycaemia (high blood sugar) can have serious consequences and can lead to headaches, nausea, vomiting, dehydration, unconsciousness, coma, and even death (see A and B in section 4 “Possible side effects”). ).

Three simple tricks to avoid hypoglycemia or hyperglycemia are:

  • Always keep spare syringes and a spare vial of Humalog, or a spare pen and cartridges , in case you lose or damage your Humalog KwikPen.
  • Always carry something with you that shows that you are diabetic.
  • Always have sugar with you.

If you stop using Humalog

You can get high blood sugar if you use too little Humalog. Do not change your insulin unless your doctor tells you to.

If you have any further questions on the use of this product, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

itching all over the bodydrop in blood pressure
breathing difficultiespalpitation
hissing breathingsweating

Local allergy is common (≥1 / 100 to <1/10). Some people get redness, swelling, or itching at the injection site. This usually stops after a few days or a few weeks. If you get any of these symptoms, talk to your doctor.

Lipodystrophy is less common (≥1 / 1000 to <1/100). If you inject insulin too often in the same place, the adipose tissue may either shrink (lipoatrophy) or thicken (lipohypertrophy). Nodules under the skin can also be caused by the accumulation of a protein called amyloid ( cutaneous amyloidosis). It may be that insulin et not work as well if you inject in an area with nodules. Change the injection site for each injection to prevent these skin changes.

Edema (swollen arms, ankles; fluid retention ) has been reported, especially when starting insulin therapy or when changing treatment to improve the control of your blood sugar.

If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your doctor or pharmacist.
