Content of the pack and other information

What CosmoFer is and what it is used for

CosmoFer contains a combination of iron and dextran (a long chain of sugar molecules).
The type of iron in CosmoFer is the same as that found naturally in the body called ‘ferritin’.
This means that you can have CosmoFer by injection in high doses.
CosmoFer is used for low levels of iron (sometimes called ‘iron deficiency’) if:

you cannot take iron by mouth, for example you cannot tolerate it

you have taken iron by mouth and it has not worked

your doctor decides you need iron very quickly to build up your iron stores.

What you need to know before you receive CosmoFer

You must not receive CosmoFer:

if you are allergic (hypersensitive) to the product or any of the other ingredients of this
medicine (listed in section 6)

if you have experienced serious allergic (hypersensitive) reactions to other injectable
iron preparations

if you have anaemia that is not caused by low levels of iron (deficiency), such as
‘haemolytic’ anaemia

if you have too much iron (overload) or a problem in the way your body uses iron

if you have liver problems such as ‘cirrhosis’ or ‘hepatitis’

if you have a bacterial or viral infection

if you have kidney problems, such as acute kidney failure.
Warnings and precautions
Talk to your doctor or nurse before receiving CosmoFer:

if you have a history of medicine allergy

if you have systemic lupus erythematosus

if you have rheumatoid arthritis

if you have severe asthma, eczema or allergies
CosmoFer is for adults only. Children under 14 should not have this medicine.
Other medicines and CosmoFer
Please tell your doctor or nurse if you are taking or have recently taken any other medicines.
This includes medicines obtained without a prescription and herbal medicines. This is because
CosmoFer can affect the way some medicines work. Also some other medicines can affect
the way CosmoFer works.
In particular tell your doctor or nurse if you are taking any of the following medicines:

vitamins and minerals

iron containing medicines you take by mouth. You should not take iron by mouth
until at least 5 days after finishing CosmoFer.
Pregnancy and breast-feeding
CosmoFer has not been tested in pregnant women. It is important to tell your doctor if you are
pregnant, think you may be pregnant, or are planning to have a baby. If you become pregnant
during treatment, you must ask your doctor for advice. Your doctor will decide whether or not
you should be given this medicine.
If you are breast-feeding, ask your doctor for advice before you are given CosmoFer.
Driving and using machines
Ask your doctor if you can drive or operate machines after having CosmoFer.
Having blood tests while you are having CosmoFer
CosmoFer may affect the results of some blood tests to measure ‘bilirubin’ and calcium. Tell your
doctor if you have any blood test while you are having CosmoFer.

How CosmoFer is given

Your doctor or nurse will administer CosmoFer by injection or infusion into your vein or you may
have it injected into your muscle; the CosmoFer will be administered in a structure where
immunoallergic events can receive appropriate and prompt treatment.
You will be observed for at least 30 minutes by your doctor or nurse after each administration.
The dose depends on your blood iron (haemoglobin) level and your weight. Your doctor will
calculate the dose for you. It is usually given to you two or three times each week.
If you get more CosmoFer than you should
A trained and qualified person will give you CosmoFer. It is unlikely that you will have too much.
They will monitor your dose so that an iron build up does not happen in your body. If you think
you have been given too much, tell your doctor or nurse straight away.

The following information is intended for healthcare professionals only:
Monitor carefully patients for signs and symptoms of hypersensitivity reactions during and
following each administration of CosmoFer.
CosmoFer should only be administered when staff trained to evaluate and manage anaphylactic
reactions is immediately available, in an environment where full resuscitation facilities can be
assured. The patient should be observed for adverse effects for at least 30 minutes following
each CosmoFer injection (see section 4.4).
CosmoFer solution for infusion and injection can be administered by an intravenous
drip infusion or by a slow intravenous injection of which the intravenous drip infusion is the
preferred route of administration, as this may help to reduce the risk of hypotensive episodes.
However, CosmoFer may also be administered as undiluted solution intramuscularly.
Adults and elderly
The total cumulative dose of CosmoFer is determined by haemoglobin level and body weight.
The dose and dosage schedule for CosmoFer must be individually estimated for each patient
based on a calculation of the total iron deficit.
Children (under 14 years)
CosmoFer should not be used for children. There is no documentation for efficacy and safety.
The normal recommended dosage schedule is 100-200 mg iron corresponding to 2-4 ml, two or
three times a week depending on the haemoglobin level. However, if clinical circumstances
require rapid delivery of iron to the body iron stores CosmoFer may be administered as a total
dose infusion up to a total replacement dose corresponding to 20 mg iron/kg body weight.
The CosmoFer injection should not be administered concomitantly with oral iron preparations as
the absorption of oral iron will be reduced (please refer to section 4.5).
Intravenous drip infusion:
CosmoFer must be diluted only in 0.9% sodium chloride solution (normal saline) or in
5% glucose solution. CosmoFer in a dose of 100-200 mg iron (2-4ml) may be diluted in 100 ml.
On each occasion the first 25 mg of iron should be infused over a period of 15 minutes. If
no adverse reactions occur during this time the remaining portion of the infusion should be
given at an infusion rate of not more than 100 ml in 30 minutes.
Intravenous injection:
CosmoFer may be administered in a dose of 100 – 200 mg iron (2-4 ml) by slow intravenous
injection (0.2 ml/min) preferably diluted in 10 – 20 ml 0.9% sodium chloride or 5% glucose
solution. On each occasion before administering a slow intravenous injection, 25 mg of iron
should be injected slowly over a period of 1 to 2 minutes. If no adverse reactions occur
within 15 minutes, the remaining portion of the injection may be given.
Total dose infusion:
Immediately before administration the total amount of CosmoFer required, determined from
the dosage table or by calculation, is added aseptically to the required volume, usually 500 ml
of sterile normal sodium chloride or 5% glucose solutions. The total amount of CosmoFer, up
to 20 mg/kg bodyweight, is infused intravenously over 4 – 6 hours. The first 25 mg of iron should
be infused over a period of 15 minutes. The patient must be kept under close medical
observation during this period. If no adverse reactions occur during this time, then the remaining
portion of the infusion should be given. The rate of infusion may be increased progressively to
45 – 60 drops per minute. Patients should be observed carefully during the infusion and for at
least 30 minutes after completion.
Total Dose Infusion (TDI) has been associated with an increased incidence of adverse reactions,
in particular delayed hypersensitivity–like reactions. The intravenous administration of
CosmoFer by the total dose infusion method should be restricted to hospital use only.
Injection into dialyser:
CosmoFer may be administered during a haemodialysis session directly into the venous limb
of the dialyser under the same procedures as outlined for intravenous administration.
Intramuscular injection:
The total amount of CosmoFer required is determined either from the dosage table or by
calculation. It is administered as a series of undiluted injections of up to 100 mg iron (2.0 ml) each
determined by the patient's body weight. If the patient is moderately active, injections may be
given daily into alternate buttocks. In inactive or bedridden patients, the frequency of injections
should be reduced to once or twice weekly.
CosmoFer must be given by deep intramuscular injection to minimise the risk of subcutaneous
staining. It should be injected only into the muscle mass of the upper outer quadrant of the
buttock - never into the arm or other exposed areas. A 20 - 21 gauge needle at least 50 mm long
should be used for normal adults. For obese patients the length should be 80 - 100 mm whereas
for small adults a shorter and smaller needle (23 gauge x 32 mm) is used. The patient should be
lying in the lateral position with the injection site uppermost, or standing bearing their weight on
the leg opposite the injection site. To avoid injection or leakage into the subcutaneous tissue, a
Z-track technique (displacement of the skin laterally prior to injection) is recommended.
CosmoFer is injected slowly and smoothly. It is important to wait for a few seconds before
withdrawing the needle to allow the muscle mass to accommodate the injection volume.
To minimise leakage up the injection track, the patient should be encouraged not to rub the
injection site.
Calculation of dose:
a) Iron replacement in patients with iron deficiency anaemia:
Factors contributing to the formula are shown below. The required dose has to be individually
adapted according to the total iron deficit calculated by the following formula – haemoglobin
in g/l or mmol/l.
Total dose (mg Fe) – Hb in g/l:
(Body weight (kg) x (target Hb - actual Hb) (g/l) x 0.24) + mg iron for iron stores
The factor 0.24 is derived from the following assumptions:
a) Blood volume 70 ml/kg of body weight ≈ 7% of body weight
b) Iron content of haemoglobin 0.34%
Factor 0.24 = 0.0034 x 0.07 x 1000 (conversion from g to mg).
Total dose (mg Fe) – Hb in mmol/l:
Body weight in kg x (target Hb in mmol/l – actual Hb in mmol/l) x 3.84 + mg iron for iron stores.
The factor 3.84 is derived from the following assumptions:
a) Blood volume 70 ml/kg of body weight ≈ 7% body weight
b) Iron content of haemoglobin 0.34%
c) Factor for conversion from haemoglobin g/l to mmol/l is 0.06205
Factor 3.84 = 0.0034 x 0.07 x 1000 / 0.06205
b) Iron replacement for blood loss:
Iron therapy in patients with blood loss should be directed toward replacement of an amount of
iron equivalent to the amount of iron represented in the blood loss. The table and formula
described are not applicable for simple iron replacement values. Quantitative estimates of the
individual’s periodic blood loss and hematocrit during the bleeding episode provide a convenient
method of calculation of the required iron dose.
The required CosmoFer dose to compensate the iron deficit is calculated according to the
following formulas:

If the volume of blood lost is known: The administration of 200 mg i.v. iron (4 ml
CosmoFer) results in an increase of haemoglobin which is equivalent to 1 unit blood
(= 400 ml with 150 g/l Hb content or 9.3 mmol Hb/l – equivalent to 0.34% of 0.4 x 150 or
204 mg iron).
Iron to be replaced [mg] = number of blood units lost x 200.
Millilitres of CosmoFer needed = number of blood units lost x 4.

If the Hb level is reduced: Use the previous formula considering that the depot iron
does not need to be restored.
