Contents of pack and other information

1. What innohep® is and what it is used for
innohep is a type of heparin – a low molecular weight heparin – and belongs to a group of medicines
called anticoagulants; these medicines affect how your blood clots. innohep prevents clotting, allowing
normal blood flow through the arteries and veins.
innohep is used to:
 Prevent blood clots in adults before and after an operation.
 Prevent blood clots in adults who have an increased risk of blood clots e.g. due to an acute illness
with limited mobility.
 Prevent blood clots being formed in haemodialysis equipment in patients undergoing
haemodialysis or haemofiltration. In haemodialysis, wastes and fluids from the blood are removed
by a dialysis machine and a dialysis filter, which acts as a kind of artificial kidney.
2. What you need to know before you use innohep®
Do not use innohep
 If you are allergic (hypersensitive) to tinzaparin or any of the other ingredients of this medicine; you
can find a list of ingredients in section 6 of this leaflet.
 If you have ever had a reaction to heparin that caused a severe drop in the number of your clotting
cells (platelets) - this reaction is called heparin-induced thrombocytopenia (HIT).
 If you have ever had a major bleed (for instance: in the brain, spine, eye or stomach, into a muscle
or the womb, or any conditions which make you bleed severely, such as haemophilia).
 If you have a condition called septic endocarditis (an inflammation of the lining of the heart and
heart valves).
Warnings and precautions
Important: If you are having an epidural/spinal anaesthetic
Your doctor will decide if you can have an epidural/spinal anaesthetic if you are using innohep.
You must wait 12 hours after your last injection of innohep before having a lumbar puncture or
epidural/spinal anaesthetic placed.

You must wait at least 4 hours after having a spinal anaesthetic, or after the catheter has been removed,
before you start using innohep again.
If you have an anaesthetic your doctor or nurse will make regular checks. This is to check if you are
getting any major bleeding or bruising around your spine. This may cause paralysis that could be
permanent. Any signs this may be happening to you include tingling, weakness or numbness in your
lower legs or body, back pain or problems in going to the toilet. This happens very rarely.
You may have a blood test before you start using this medicine and at intervals while you are using it;
this is to check the level of the clotting cells (platelets) and potassium in your blood.
Do not inject innohep into a muscle. See section 3, “How to use innohep®”.
This medicine may make you bleed more easily, so when you are being given other injections or having
any procedures carried out, tell the doctor, nurse or dentist that you are using innohep.
Talk to your doctor, pharmacist or nurse before using innohep
 If you are pregnant, or think you may be pregnant. See the section “Pregnancy and breastfeeding”.
 If you have a condition which makes you more likely to bleed.
 If you are being treated with any other injections into your muscles.
 If you are allergic (hypersensitive) to heparin.
 If you are allergic to other low molecular weight heparins, such as enoxaparin or dalteparin.
 If you have any medical condition such as diabetes mellitus or metabolic acidosis which may
cause high levels of potassium in your blood (hyperkalaemia).
 If you have an artificial heart valve.
 If you have kidney problems.
innohep should not be interchanged with other low molecular weight heparin products. This is because
they are not exactly the same and you could experience problems with your blood clotting.
Elderly people
Because kidney problems are more likely if you are elderly, you may have a blood test to check how
well your kidneys are working and to monitor the activity of innohep.
Children and adolescents
innohep is not intended for use in children and adolescents under the age of 18 years.
Other medicines and innohep
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
medicines. This includes any medicines bought without a prescription.
You must tell your doctor or pharmacist if you are taking any of the following medicines as you may
be likely to bleed more easily:
 Non-steroidal anti-inflammatory drugs (such as ibuprofen or diclofenac): for arthritis or aches or
 Aspirin: either for reducing pain and inflammation, or the lower dose for thinning of the blood.
 Platelet aggregation inhibitors (such as clopidogrel): for stopping harmful blood clots forming.
 Thrombolytic agents (such as streptokinase): for dissolving blood clots.
 Vitamin K antagonists (such as warfarin): for stopping harmful blood clots.
 Activated protein C: for getting rid of blood clots.
 Anticoagulation, taken by mouth (such as rivaroxaban, dabigatran or apixaban): for stopping
harmful blood clots.

Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask
your doctor, pharmacist or midwife for advice before using this medicine.
Special precautions are required if you will have an epidural anaesthetic to help you with your labour
when you are using innohep. (See “Warnings and precautions”.)
Driving and using machines
This medicine should not have any effect on your ability to drive or use machines. However, you
should check with your doctor if you feel any side effect that may stop you from driving or using
Important information about some of the ingredients of innohep
innohep 10,000 IU/ml syringe contains:
 Sodium. This medicine is nearly “sodium free”. Your medicine contains less than 23 milligrams
(mg) of sodium per dose.
Please ask your doctor or pharmacist if you are worried about any of the ingredients in this medicine.
How to use innohep®
Your doctor may decide that you or a carer may inject this medicine. You will be shown how to do the
injection and should only do the injection when you have been instructed how to do so.
Always use this medicine exactly as your doctor, pharmacist or nurse has told you. Check with one of
them if you are not sure that you understand how to do the injection or if you are unsure about
anything else to do with the medicine.
How much innohep to use
Adults, including the elderly:
To prevent blood clots forming in your veins
innohep must be injected under the skin (subcutaneous injection). The dose and the length of your
treatment will depend on the type of operation or illness you are having. Your doctor will prescribe the
right dose for you and tell you how long your treatment with innohep will last.
To prevent blood clots forming in connection with haemodialysis or haemofiltration
innohep will be given either into the tubes of the haemodialysis machine or into your vein. The dose
will depend on the duration of dialysis.
Use in children and adolescents
There is limited experience of use in children and adolescents. innohep is not intended for use in
children and adolescents under the age of 18 years.
How to inject yourself with innohep
You should inject yourself exactly as you have been shown and only on the parts of your body that you
have been told it is safe to inject into. The type of injection you will be giving is known as a
subcutaneous injection. The injection goes into a pinched up fatty layer on your abdomen, or on the
outer part of your thighs, lower back, upper leg or upper arm. Keep away from your belly button. Do
NOT inject into a muscle.
Ideally you should inject at the same time every day; this helps to maintain a steady level of the
medicine in your body.
When giving yourself an injection, make sure you:

1. Thoroughly wash and dry your hands.
2. Sit, stand or lie in a position so that you can see the skin where you are going to inject yourself. This
can comfortably be done standing up, or if you prefer, in a lounge chair, recliner or bed propped up
with pillows.

3. Decide where to inject yourself. This is usually on the right or left side of the abdomen remembering
not to inject yourself within 5 cm (2 inches) of your belly button. You may also inject into the sides of
your thigh, lower back, upper leg or upper arm. Do not inject near any scars or bruises. Each time you
inject yourself, choose the opposite side from the site of your previous injection. So if you injected
your right thigh last time, you would inject your left thigh next time. If you are injecting in your
abdomen, you would do the left side one day and right the next. You should also avoid injecting into the
exact site of a previous injection.
4. Clean the chosen area of the skin, as you have been told to do by your doctor or nurse, and allow to
dry before you inject yourself.

Carefully take the syringe out of its plastic container by bending the cap all the way back and sliding the
syringe out. Bend the orange safety device down away from the cap on the needle. Remove the
protective needle cap without bending the needle. To keep the needle clean, make sure it does not touch
anything. The syringe is now ready for use.

5. Hold the syringe in your writing-hand like you would hold a pen. With your other hand, make a fold
of your skin by gently pinching the area where you are going to inject yourself with your thumb and
6. With the syringe at a right angle to your body (pointing straight, not at an angle), insert the needle
fully into the skin fold.
7. Continue to hold the skin fold, press down on the plunger slowly over 10-15 seconds. This delivers
this medicine into the fatty tissue.
8. Pull the needle completely out of the skin and then let go of the skin fold. Do not rub or massage the
place where you injected yourself – this can lead to bruising.

9. Using a hard surface, bend the orange safety device so it is now pointing in the same direction as the
needle (back to its original position). Then with the safety device flat against a hard surface such as a
table, gently push downwards until the needle clicks into the device. Then continue to push downwards
against the hard surface, so that the needle and device are at a 45 degree angle to the syringe.

10. The used syringe, even when the orange safety device is in place, should be handled with care and
should be disposed of in a “sharps” container (i.e. a special bin for needles) immediately. If a “sharps”
container is not readily available then please put the used syringe back into the plastic container and

close the lid by pressing down on the lid until it clicks into the slot provided. Dispose of the syringe
carefully, as instructed by your healthcare professional.
Never put syringes or needles in the household rubbish.
For the attention of the healthcare professional:
Please dispose of the used syringe in accordance with your institution/employer’s standard procedures
for disposal of used syringes.
If you use more innohep than you should
If you think you may have injected yourself with too much, tell your doctor or nurse straight away
because you may start to haemorrhage (bleed severely) and need to be given another injection of a
medicine called protamine sulfate to stop you bleeding.
If you have missed a dose of innohep
If you forget to have your injection, it is important that you talk to your doctor or nurse as soon as you
remember and get advice on what to do.
Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
The side effects most often reported are blood problems and skin reactions, especially where your
injection has been given.
Important side effects to look out for:
You must get urgent medical help if you have any of the following symptoms. You may be having
a serious allergic reaction. These are rare (may affect 1 in 1000 people).

You have difficulty breathing.

Your face or throat swell.

Your skin develops a severe rash.

You experience blistering of the skin, mouth, eyes or genitals or your skin peels.

Blood spots near the injection site which could develop into a purple blister surrounded by red
inflamed skin.
You must get urgent medical help if you have any of the following symptoms after having an
epidural or spinal anaesthetic. You may be developing paralysis:

Tingling, weakness or numbness in your legs or lower body.

Back pain.

Problems in going to the toilet.
You should tell your doctor straight away if you spot any of the following signs which mean you
may be starting to bleed severely:

Red or brown urine.

Black tarry stools.

Unusual bruising.

Bleeding from your nose, or mouth or any operation wound that will not stop.
Common side effects (may affect up to 1 in 10 people)

Bleeding (haemorrhage).

Anaemia. Reduction in red blood cells which can make the skin pale and cause weakness and

A pooling of blood in tissues which may result in the skin appearing dark in colour, similar to a
large bruise.

Pain, itching, bruising or bleeding, redness, swelling, nodules or hard lumps under your skin
where the injection was given.

Uncommon side effects (may affect up to 1 in 100 people)

Changes in your blood test results. There may be a change in the clotting cells (platelets) in your
blood. These tests will return to normal when innohep is stopped.

An allergic reaction. You may be sensitive to one of the ingredients in this medicine.

Bruising, red or purple spots under your skin.

Some blood tests may also show a change in the way your liver is working. These tests will
return to normal when innohep is stopped.

An itchy red rash with heat and swelling on your skin (dermatitis).


Itchy skin.
Rare side effects (may affect up to 1 in 1000 people)

Your blood may form more harmful clots. A drop in the number of clotting cells (platelets) in
your blood may give you these symptoms. Your doctor can explain this more.

Changes in your blood test results. The amount of potassium may be increased. This is more
likely to happen if you have severe kidney problems or diabetes. Your doctor can explain this


Your bones may weaken and break more easily. This is known as osteoporosis and has been seen
in patients using heparin for a long time.
