Patient leaflet - MONOFER 100 MG / ML SOLUTION FOR INJECTION/INFUSION
1. what monofer is and what it is used for
Monofer contains a combination of iron and derisomaltose (a chain of sugar molecules). The type of iron in Monofer is the same as that found naturally in the body called ‘ferritin’. This means that you can have Monofer by injection in high doses.
Monofer is used for low levels of iron (sometimes called ‘iron deficiency’ and ‘iron deficiency anaemia’) if:
- Oral iron does not work or you cannot tolerate it
- Your doctor decides you need iron very quickly to build up your iron stores
93×18–04-xx

2. what you need to know before you receive monofer
You must not receive Monofer if you:
- are allergic (hypersensitive) to the product or any of the other ingredients of this medicine (listed in section 6).
- have experienced serious allergic (hypersensitive) reactions to other injectable iron preparations.
- have anaemia not caused by iron deficiency
- have too much iron (overload) or a problem in the way your body uses iron
- have liver problems such as ‘cirrhosis’
Warnings and precautions
Talk to your doctor or nurse before receiving Monofer if you:
- have a history of medicine allergy
- have systemic lupus erythematosus
- have rheumatoid arthritis
- have severe asthma, eczema or other allergies
- have an ongoing bacterial infection in your blood
- have reduced liver function
Incorrect administration of Monofer may cause leakage of the product at the injection site, which may lead to irritation of the skin and potentially long lasting brown discolouration at the site of injection. The administration must be stopped immediately when this occurs.
Children and adolescents
Monofer is for adults only. Children and adolescents should not have this medicine.
Other medicines and Monofer
Tell your doctor if you are using, have recently used or might use any other medicines.
Monofer given together with oral iron preparations can reduce the absorption of oral iron.
Pregnancy and breast-feeding
Monofer 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 Monofer. It is unlikely that Monofer represents a risk to the nursing child.
Driving and using machines
Ask your doctor if you can drive or operate machines after having Monofer.

3. How Monofer is administered
Before administration, your doctor will perform a blood test to determine the dose of Monofer you require.
Your doctor or nurse will administer Monofer by injection or infusion into your vein.
- Monofer may be administered as an intravenous injection up to 500 mg up to three times a week.
- Monofer may be administered during a dialysis session
- Monofer may be administered as an intravenous infusion in a dose up to 20 mg iron/kg body weight or as weekly infusions until the total dose has been administered.
Monofer 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.
If you receive more Monofer than you should
A qualified health care professional will give you Monofer. It is unlikely that you will have too much. They will monitor your dose and blood to avoid iron building up in your body.
4. possible side effects
Like all medicines, Monofer can cause side effects, although not everybody gets them.

Reporting of side effects
If you get any side effects, talk to your doctor 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, Website: or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.
The following information is intended for medical or healthcare professionals only:
Monitor carefully patients for signs and symptoms of hypersensitivity reactions during and following each administration of Monofer. Monofer 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 Monofer injection.
Each IV iron administration is associated with a risk of a hypersensitivity reaction. Thus, to minimise risk the number of single IV iron administrations should be kept to a minimum.
Posology
The posology of Monofer follows a stepwise approach: [1] determination of the individual iron need and [2] calculation and administration of the iron dose(s). The steps can be repeated after [3] post-iron repletion assessments.
Step 1: Determination of the iron need:
The iron need can be determined using either the Simplified Table (i) or the Ganzoni formula below (ii).
The iron need is expressed in mg elemental iron.
i. Simplified Table:
Table 1. Simplified Table
Hb (g/dl) | Hb (mmol/l) | Patients with bodyweight <50 kg | Patients with bodyweight 50 kg to <70 kg ' | Patients with bodyweight >70 kg |
>10 | >6.2 | 500 mg | 1000 mg | 1500 mg |
<10 | <6.2 | 500 mg | 1500 mg | 2000 mg |
ii. Ganzoni formula:
Table 2. Ganzoni formula
Iron need = Body weight(A) x (Target Hb(D) – Actual Hb)(B) x 2.4 + Iron for iron stores© [mg iron] [kg] [g/dl] [mg iron]
-
(A) It is recommended to use the patient’s ideal body weight for obese patients or pre-pregnancy weight for pregnant women. For all other patients use actual body weight.
Ideal body weight may be calculated in a number of ways e.g. by calculating weight at BMI 25 i.e. ideal body weight = 25 * (height in m)2
-
(B) To convert Hb [mM] to Hb [g/dl] you should multiply Hb [mM] by factor 1.61145
-
© For a person with a body weight above 35 kg, the iron stores are 500 mg or above. Iron stores of 500 mg are at the lower limit normal for small women. Some guidelines suggest using 10–15 mg iron /kg body weight.
-
(D) Default Hb target is 15 g/dl in the Ganzoni formula. In special cases such as pregnancy consider using a lower haemoglobin target.
