What Humulin S KwikPen is and what it is used for

Humulin S KwikPen is a pre-filled pen containing the active substance human insulin, which
is used to treat diabetes. You get diabetes if your pancreas does not make enough insulin to
control the level of glucose in your blood (blood sugar). Humulin S is used to control glucose
in the long term. Humulin S is a rapidly acting insulin preparation.
Your doctor may tell you to use Humulin S KwikPen as well as a longer-acting insulin. Each
kind of insulin comes with its own patient information leaflet to tell you about it. Do not
change your insulin unless your doctor tells you to. Be very careful if you do change insulin.
Each type of insulin has a different colour and symbol on the pack and the pen so that you
can easily tell the difference.


What you need to know before you use Humulin S KwikPen

Do not use Humulin S KwikPen:
If you think hypoglycaemia (low blood sugar) is starting. Further in this leaflet it
tells you how to deal with mild hypoglycaemia (see A in Section 4).
If you are allergic to human insulin or any of the other ingredients of this medicine
(listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Humulin S KwikPen

If your blood sugar levels are well controlled by your current insulin therapy, you may
not feel the warning symptoms when your blood sugar is falling too low. Warning
signs are listed later in this leaflet. You must think carefully about when to have your

meals, how often to exercise and how much to do. You must also keep a close watch on
your blood sugar levels by testing your blood glucose often.
A few people who have had hypoglycaemia (low blood sugar) after switching from
animal insulin to human insulin have reported that the early warning symptoms were
less obvious or different. If you often have hypoglycaemia or have difficulty
recognising the symptoms, please discuss this with your doctor.
If you answer YES to any of the following questions, tell your diabetes specialist nurse,
doctor or pharmacist.
Have you recently become ill?
Do you have trouble with your kidneys or liver?
Are you exercising more than usual?
The amount of insulin you need may also change if you drink alcohol.
You should also tell your diabetes specialist nurse, doctor or pharmacist if you are
planning to go abroad. The time difference between countries may mean that you have
to have your injections and meals at different times to when you are at home.
Some patients with long-standing type 2 diabetes mellitus and heart disease or previous
stroke who were treated with pioglitazone and insulin experienced the development of
heart failure. Inform your doctor as soon as possible, if you experience signs of heart
failure such as unusual shortness of breath or rapid increase in weight or localised
swelling (oedema).

Other medicines and Humulin S KwikPen
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
Your insulin needs may change if you are taking any of the following:


thyroid hormone replacement therapy,

oral hypoglycaemics (antidiabetic medication),

acetylsalicylic acid (aspirin),

growth hormone,

octreotide, lanreotide,

beta2 stimulants (for example ritodrine, salbutamol or terbutaline),


thiazides or some antidepressants (monoamine oxidase inhibitors),


some angiotensin converting (ACE) inhibitors (for example captopril, enalapril) or
angiotensin II receptor blockers.
Pregnancy, breast-feeding and fertility
The amount of insulin you need usually falls during the first three months of pregnancy and
increases for the remaining six months. If you are breast-feeding, you may need to alter your
insulin intake or diet.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a
baby, ask your doctor or pharmacist for advice before using this medicine.
Driving and using machines
Your ability to concentrate and react may be reduced if you have hypoglycaemia (low blood
sugar). Please remember this in all situations where you might put yourself and others at risk
(e.g. driving a car or operating machinery). You should contact your diabetes specialist nurse
or doctor about the advisability of driving if you have:

frequent episodes of hypoglycaemia
reduced or absent warning signs of hypoglycaemia.


How to use Humulin S KwikPen

Always check the pack and the label of the pre-filled pen for the name and type of the
insulin when you get it from your pharmacy. Make sure you get the Humulin KwikPen
that your doctor has told you to use.
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your
doctor or pharmacist if you are not sure. To prevent the possible transmission of disease, each
pen must be used by you only, even if the needle is changed.

Your doctor has told you which insulin to use, how much, when and how often to
inject. These instructions are only for you. Follow them exactly and visit your diabetes
clinic regularly.

If you change your insulin type (for example from animal to human), you may have to
take more or less than before. This might just be for the first injection or it may be a
gradual change over several weeks or months.

Inject Humulin S under the skin. You should only inject it into a muscle if your doctor
has told you to.
Preparing Humulin S KwikPen

Humulin S is already dissolved in water, so you do not need to mix it. But you must
use it only if it looks like water. It must be clear, have no colour and no solid particles
in it. Check each time you inject yourself.
Getting the KwikPen ready to use (Please see user manual)

First wash your hands.

Read the instructions on how to use your pre-filled insulin pen. Please follow the
instructions carefully. Here are some reminders.
Use a clean needle. (Needles are not included).
Prime your KwikPen before each use. This checks that insulin comes out and
clears the air bubbles from your KwikPen. There may still be some small air
bubbles left in the KwikPen - these are harmless, but if the air bubble is too big, it
may make the dose of your injection less accurate.
Injecting Humulin S KwikPen

Before you make an injection, clean your skin as you have been instructed. Inject under
the skin, as you were taught. Do not inject directly into a vein. After your injection,
leave the needle in the skin for 5 seconds to make sure you have taken the whole dose.
Do not rub the area you have just injected. Make sure you inject at least half an inch
(1 cm) from where you last injected and that you ‘rotate’ the places you inject, as you
have been taught.

You must not inject Humulin S KwikPen into a vein. Inject Humulin S KwikPen as
your diabetes specialist nurse or doctor has taught you. Only your doctor can inject
Humulin S KwikPen into a vein. He or she will only do this under special
circumstances such as surgery or if you are ill and your glucose levels are too high.
After injecting

As soon as you have done the injection, unscrew the needle from the KwikPen using
the outer needle cap. This will keep the insulin sterile and prevent leaking. It will also


stop air going back into the KwikPen and the needle clogging up. Do not share your
needles or your KwikPen. Replace the cap on the KwikPen.
Further injections

Every time you use a KwikPen you must use a new needle. Before every injection,
clear any air bubbles. You can see how much insulin is left by holding the KwikPen
with the needle pointing down. The scale on the cartridge shows about how many units
you have left.

Do not mix any other insulin in your disposable KwikPen. Once the KwikPen is empty,
do not use it again. Please get rid of it carefully - your diabetes specialist nurse or
pharmacist will tell you how to do this.
If you use more Humulin S than you should
If you use more Humulin S than you should, your blood sugar may become low. Check your
blood sugar (see A in section 4).
If you forget to use Humulin S KwikPen
If you use less Humulin S than you should, your blood sugar levels may increase. Check your
blood sugar. Do not inject a double dose to make up for a forgotten dose.
If you stop using Humulin S KwikPen
If you use less Humulin S than you should, your blood sugar levels may become too high. Do
not change your insulin unless your doctor tells you to.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist, or


Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Human insulin may cause hypoglycaemia (low blood sugar). See more information on
hypoglycaemia below in the subsection “Common problems of diabetes”.
Possible side effects
Systemic allergy is very rare (affects less than 1 person in 10,000). The symptoms are as

fall in blood pressure

rash over the whole body

difficulty in breathing


fast heart beat

If you think you are having this sort of insulin allergy with Humulin S, tell your doctor at
Local allergy is common (affects less than 1 person in 10). Some people get redness,
swelling or itching around the area of the insulin injection. This usually clears up in anything
from a few days to a few weeks. If this happens to you, tell your doctor.
Lipodystrophy (thickening or pitting of the skin) is uncommon (affects less than 1 person in
100). If you notice your skin thickening or pitting at the injection site, change your injection
site and tell your doctor.
Oedema (e.g. swelling in arms, ankles; fluid retention) has been reported, particularly at the
start of insulin therapy or during a change in therapy to improve control of your blood

Common problems of diabetes
Hypoglycaemia (low blood sugar) means there is not enough sugar in the blood. This can be
caused if you:

take too much Humulin S or other insulin;

miss or delay meals or change your diet;

exercise or work too hard just before or after a meal;

have an infection or illness (especially diarrhoea or vomiting);

have a change in your need for insulin; or

have trouble with your kidneys or liver which gets worse.
Alcohol and some medicines can affect your blood sugar levels.
The first symptoms of low blood sugar usually come on quickly and include the following:


rapid heartbeat

nervousness or shakiness

feeling sick


cold sweat
Until you become confident in recognising your warning symptoms, avoid situations such as
driving a car, in which you or others would be put at risk by hypoglycaemia.
Do not use Humulin S if you think hypoglycaemia (low blood sugar) is starting.
If your blood sugar is low, eat glucose tablets, sugar or drink a sugary drink. Then eat fruit,
biscuits, or a sandwich, as your doctor has advised you and have some rest. This will often
get you over mild hypoglycaemia or a minor insulin overdose. If you get worse and your
breathing is shallow and your skin gets pale, tell your doctor at once. A glucagon injection
can treat quite severe hypoglycaemia. Eat glucose or sugar after the glucagon injection. If you
do not respond to glucagon, you will have to go to hospital. Ask your doctor to tell you about
Hyperglycaemia and diabetic ketoacidosis
Hyperglycaemia (too much sugar in the blood) means that your body does not have enough
insulin. Hyperglycaemia can be brought about by:

not taking your Humulin or other insulin;

taking less insulin than your doctor tells you to;

eating a lot more than your diet allows; or

fever, infection or emotional stress.
Hyperglycaemia can lead to diabetic ketoacidosis. The first symptoms come on slowly over
many hours or days. The symptoms include the following:

feeling sleepy

no appetite

flushed face

fruity smell on the breath


feeling or being sick
Severe symptoms are heavy breathing and a rapid pulse. Get medical help immediately.
If hypoglycaemia (low blood sugar) or hyperglycaemia (high blood sugar) are not treated
they can be very serious and cause headaches, nausea, vomiting, dehydration,
unconsciousness, coma or even death.
Three simple steps to avoid hypoglycaemia or hyperglycaemia are:
• Always keep spare syringes and a spare vial of Humulin S.
• Always carry something to show you are diabetic.

• Always carry sugar with you.
If you are ill, especially if you feel sick or are sick, the amount of insulin you need may
change. Even when you are not eating normally, you still need insulin. Test your urine or
blood, follow your ‘sick rules’, and tell your diabetes specialist nurse or doctor.
Reporting of side effects
If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any
possible side effects not listed in this leaflet. You can also report side effects directly via
United Kingdom: Yellow Card Scheme, website: By
reporting side effects you can help provide more information on the safety of this medicine.

Contents of the pack and other information

What Humulin S KwikPen contains
- The active substance is human insulin. Human insulin is made in the laboratory by a
‘recombinant DNA technology’ process. It has the same structure as the natural
hormone made by the pancreas. It is therefore different from animal insulins.

The other ingredients are metacresol, glycerol and water for injection. Sodium
hydroxide or hydrochloric acid may have been used during manufacture to adjust the

Priming your Pen
Prime before each injection.

Priming your Pen means removing the air from the Needle and Cartridge that may collect
during normal use and ensures that the Pen is working correctly.

If you do not prime before each injection, you may get too much or too little insulin.

Step 6:

To prime your Pen, turn the Dose
Knob to select 2 units.

Step 7:

Hold your Pen with the Needle
pointing up. Tap the Cartridge Holder
gently to collect air bubbles at the top.

the priming steps, but not more
than 4 times.

If you still do not see insulin,
change the Needle and repeat the
priming steps.

Small air bubbles are normal and will not
affect your dose.

Selecting your dose

You can give from 1 to 60 units in a single injection.

If your dose is more than 60 units, you will need to give more than one injection.

If you need help deciding how to divide up your dose, ask your healthcare

You should use a new Needle for each injection and repeat the priming step.

Step 9:

Turn the Dose Knob to select the
number of units you need to inject.
The Dose Indicator should line up

DO NOT dial your dose by
counting the clicks because you
may dial the wrong dose.

The dose can be corrected by
turning the Dose Knob in either
direction until the correct dose
lines up with the Dose

The even numbers are printed
on the dial.

(Example: 12 units
shown in the Dose

(Example: 25 units

The odd numbers, after the
number 1, are shown as full

Always check the number in the
Dose Window to make sure you
have dialed the correct dose.

The Pen will not let you dial more than the number of units left in the Pen.

If you need to inject more than the number of units left in the Pen, you may either:

inject the amount left in your Pen and then use a new Pen to give the rest of your
dose, or

get a new Pen and inject the full dose.

It is normal to see a small amount of insulin left in the Pen that you cannot inject.

Giving your injection

Inject your insulin as your healthcare professional has shown you.

Change (rotate) your injection site for each injection.

Do not try to change your dose while injecting.

Step 10:

Choose your injection site.
Humulin is injected under the skin
