Humulin® M3 100IU/ml
Suspension for injection in a vial
(insulin, human)
Read all of this leaflet carefully before you start using this medicine.
• Keep this leaflet. You may need to read it again.
• If you have any further questions, ask your diabetes specialist nurse,
doctor or pharmacist.
• This medicine has been prescribed for you. Do not pass it on to others.
It may harm them, even if their symptoms are the same as yours.
• If any of the side effects gets serious, or if you notice any side effects
not listed in this leaflet, please tell your diabetes specialist nurse,
doctor or pharmacist.
• The name of this medicine is Humulin M3 100IU/ml Suspension for
injection in a vial but will be referred to as Humulin M3 throughout the
remainder of this leaflet.
In this leaflet:
1) What Humulin M3 is and what it is used for
2) Before you use Humulin M3
3) How to use Humulin M3
4) Possible side effects
5) How to store Humulin M3
6) Further information
Humulin M3 contains 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 M3 is used to control glucose in the long term. It is a premixed
suspension of rapid and long acting insulin. Its action is prolonged by the
inclusion of protamine sulphate in the suspension.
Your doctor may tell you to use Humulin M3 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 vial so that you can
easily tell the difference.
Do not use Humulin M3 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).
– are allergic (hypersensitive) to human insulin or any of the other
ingredients of Humulin M3 (see section 6).
Take special care with Humulin M3
• 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).
Using other medicines
Please tell your doctor or diabetes specialist nurse, if you are taking or
have recently taken any other medicines, including medicines obtained
without a prescription.
Your insulin needs may change if you are taking any of the following:
• steroids,
• thyroid hormone replacement therapy,
• oral hypoglycaemics (antidiabetic medication),
• acetylsalicylic acid (aspirin),
• growth hormone,
• octreotide, lanreotide,
• beta2 stimulants (for example ritodrine, salbutamol or terbutaline),
• beta-blockers,
• thiazides or some antidepressants (monoamine oxidase inhibitors),
• danazol,
• some angiotensin converting (ACE) inhibitors (for example captopril,
enalapril) or angiotensin II receptor blockers.

Pregnancy and breast-feeding
Ask your doctor or diabetes specialist nurse for advice before taking any
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.
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.
Always check the pack and the vial label for the name and type of
the insulin when you get it from your pharmacy. Make sure you get
the Humulin that your doctor has told you to use.
Always use Humulin M3 exactly as your doctor has told you. You should
check with your doctor if you are not sure.
• 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
• Inject Humulin M3 under the skin. You should not administer it using a
different administration route. Under no circumstances should Humulin
M3 be given into a vein.
Preparing Humulin M3
• Vials containing Humulin M3 should be rotated several times in the
palms of the hands before use to resuspend insulin until it appears
uniformly cloudy or milky. If not, repeat the above procedure until
contents are mixed. Do not shake vigorously as this may cause
frothing which may interfere with the correct measurement of the dose.
The vials should be examined frequently and should not be used if
clumps of material are present or if solid white particles stick to the
bottom or sides of the vial, giving it a frosted appearance. Check each
time you inject yourself.
Injecting Humulin M3
• First wash your hands.
• Before you make an injection, clean your skin as you have been
instructed. Clean the rubber stopper on the vial, but do not remove the
• Use a clean, sterile syringe and needle to pierce the rubber stopper
and draw in the amount of Humulin M3 you want. Your doctor or clinic
will tell you how to do this. Do not share your needles and syringes.
• 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.
If you take more Humulin M3 than you need
If you take more Humulin M3 than you need, your blood sugar may
become low. Check your blood sugar (see A in Section 4).
If you forget to use Humulin M3
If you take less Humulin M3 than you need, your blood sugar levels may
increase. Check your blood sugar.
If you stop using Humulin M3
If you take less Humulin M3 than you need, your blood sugar levels may
become too high. Do not change your insulin unless your doctor tells you
If you have any further questions on the use of this product, ask your
diabetes specialist nurse, doctor or pharmacist.
Like all medicines, Humulin M3 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 follows:
• fall in blood pressure
• rash over the whole body
• difficulty in breathing
• wheezing
• fast heart beat
• sweating
If you think you are having this sort of insulin allergy with Humulin M3, tell
your doctor at once.
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 glucose.
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.
Common problems of diabetes
A. Hypoglycaemia
Hypoglycaemia (low blood sugar) means there is not enough sugar in the
blood. This can be caused if you:
• take too much Humulin M3 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:
• tiredness
• rapid heartbeat
• nervousness or shakiness
• feeling sick
• headache
• 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 M3 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 glucagon.
B. 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 M3 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
• feeling sleepy
• no appetite
• flushed face
• fruity smell on the breath
• thirst
• 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 M3.
• Always carry something to show you are diabetic.
• Always carry sugar with you.
C. Illness
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 the Yellow Card Scheme at:
By reporting side effects you can help provide more information on the
safety of this medicine.

• Keep out of the sight and reach of children.

• Keep the container in the outer carton to protect from light
• Do not use Humulin M3 after the expiry date which is stated on the
label and the carton. The expiry date refers to the last day of that
• Do not use Humulin M3, if clumps of material are present or if solid
white particles stick to the bottom or sides of the vial, giving it a frosted
appearance. Check this each time you inject yourself.
• If your medicine shows any sign of deterioration, return it to your
• Medicines should not be disposed of via wastewater or household
waste. Ask your pharmacist how to dispose of medicines no longer
required. These measures will help to protect the environment.
What Humulin M3 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. Humulin M3 is a premixed suspension
which contains 30 % insulin dissolved in water and 70% insulin with
protamine sulphate.
The other ingredients are metacresol, glycerol, phenol, protamine
sulphate, dibasic sodium phosphate heptahydrate, zinc oxide, water for
injections. Hydrochloric acid and/or sodium hydroxide may have been
used during manufacture to adjust the acidity.
What Humulin M3 looks like and contents of the pack
Humulin M3 100 IU/ml suspension for injection is a white, sterile
suspension and contains 100 units of insulin in each millilitre (100 IU/ml).
Each vial contains 10ml equivalent to 1000IU of biphasic isophane insulin
- 30% soluble insulin/70% isophane insulin.
