What MONOFER is used for

Monofer is a medicine that is used to treat iron deficiency resulting in anaemia when oral iron preparations are ineffective or cannot be used. It contains iron in the form of ferric derisomaltose.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another purpose.

Monofer is only available with a doctor’s prescription. It is not addictive.

Before you are given MONOFER

When you must not be given it

You must not have Monofer if you have ever had an allergic reaction to ferric derisomaltose, the active ingredient in Monofer.

Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

You must not have Monofer if:

  • you have anaemia that is not caused by iron deficiency
  • you have too much iron (overload) or a problem with the way your body uses iron

There is not enough information to recommend the use of Monofer in children.

Before you are given it

Tell your doctor if you have any of the following medical conditions:

  • liver problems
  • systemic lupus erythematosus (SLE) or a related disease
  • rheumatoid arthritis
  • severe asthma, eczema or other allergies
  • ongoing bacterial infection in your blood.

If you are not sure whether any of the above conditions apply to you, ask your doctor. Your doctor may want to take special precautions if you have any of these conditions.

Tell your doctor if you are pregnant or planning to become pregnant.

Ask your doctor about the risks and benefits involved in treatment with Monofer during pregnancy.

Tell your doctor if you are breast-feeding.

Monofer may slow the heart rate of your unborn baby for a short time if you have an allergic reaction to Monofer. Your doctor will carefully monitor your unborn baby while you are being given Monofer while pregnant.

While it is unlikely to affect your baby, you should ask your doctor for advice before you are given Monofer.

Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives. Your doctor will want to know if you are prone to allergies.

Taking or being given other medicines

Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.

Monofer given together with oral iron preparations can reduce the absorption of oral iron.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while you are receiving Monofer.

How MONOFER is given

How much you need

Your doctor will perform a blood test to determine the iron levels in your body. This will then help your doctor calculate the dose of Monofer you require.

How it is given

Monofer is usually given in a clinical setting equipped to provide intravenous infusions. The solution in the vial may be diluted with 0.9% sodium chloride. It can be given by slow injection directly from the syringe into a vein, or by infusion (drip) over a longer period, or during a haemodialysis session if you are receiving dialysis treatment.

Your doctor or nurse will observe you for at least 30 minutes after your Monofer injection.

How long your treatment will last

Your doctor will determine how long you will need to receive treatment with Monofer. You may receive a single infusion, or several infusions over several weeks.

If you have too much (overdose)

Too much Monofer may lead to accumulation of iron in your body. Your doctor will monitor the levels of iron in your body to make sure that you do not receive too much Monofer.

While you are being given MONOFER

Things you must do

Before having any surgery or emergency treatment, tell the doctor that you are being treated with Monofer.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are being treated with Monofer.

Tell any other doctor, dentist or pharmacist who treats you that you are being treated with Monofer.

Things to be careful of

Your doctor will need to be careful during treatment to avoid any leakage into your skin around the injection site. If a leak occurs the treatment must be stopped. If there is any leak of Monofer at the injection site it may cause irritation of the skin or a brown discolouration at the injection site. Discolouration in other areas can also occur.
