1. What IVEMEND is and what it is used for

IVEMEND contains the active substance fosaprepitant which is converted to aprepitant in your body. It belongs to a group of medicines called "neurokinin 1 (NK1) receptor antagonists". The brain has a specific area that controls nausea and vomiting. IVEMEND works by blocking signals to that area, thereby reducing nausea and vomiting. IVEMEND is used in adults, adolescents, and children aged 6 months or older in combination with other medicines to prevent nausea and vomiting caused by chemotherapy (cancer treatment) that is a strong or moderate trigger of nausea and vomiting.

2. What you need to know before you use IVEMEND
Do not use IVEMEND
  • if you are allergic to fosaprepitant, aprepitant, or to polysorbate 80 or any of the other ingredients of this medicine (listed in section 6).
  • with medicines containing pimozide (used to treat psychiatric illnesses), terfenadine and astemizole (used for hay fever and other allergic conditions), cisapride (used for treating digestive problems). Tell your doctor if you are taking these medicines since the treatment must be modified before you start using IVEMEND.

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before using IVEMEND.

Before treatment with this medicine, tell your doctor if you have liver disease because the liver is important in breaking down the medicine in the body. Your doctor may therefore have to monitor the condition of your liver.

Children and adolescents

Do not give IVEMEND to children under 6 months of age or who weigh less than 6 kg, because it has not been studied in this population.

IVEMEND can affect other medicines both during and after treatment with IVEMEND. There are some medicines that should not be taken with IVEMEND (such as pimozide, terfenadine, astemizole, and cisapride) or that require a dose adjustment (see also ‘Do not use IVEMEND’).

This medicine should not be used during pregnancy unless clearly necessary. If you are pregnant or breast-feeding, may be pregnant or are planning to have a baby, ask your doctor for advice before receiving this medicine.

For information regarding birth control, see ‘Other medicines and IVEMEND’.

Driving and using machines

It should be taken into account that some people get dizzy and get sleepy after using IVEMEND. If you get dizzy or get sleepy, avoid driving or using machines after using this medicine (see ‘Possible side effects’).

IVEMEND contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially ‘sodium-free’.

3. How to use IVEMEND

In adults (18 years of age and older), the recommended dose of IVEMEND is 150 mg fosaprepitant on Day 1 (day of chemotherapy).

In children and adolescents (6 months to 17 years of age), the recommended dose of IVEMEND is based on the patient’s age and weight. Depending on the chemotherapy treatment, there are two ways IVEMEND may be given:

IVEMEND is given only on Day 1 (single day of chemotherapy)

IVEMEND is given on Day 1, 2, and 3 (single or multiple days of chemotherapy)

  • Oral formulations of aprepitant may be prescribed on Days 2 and 3 instead of IVEMEND.

The powder is reconstituted and diluted before use. The solution for infusion is given to you by a health care professional, such as a doctor or nurse, via an intravenous infusion (a drip) approximately 30 minutes before you start the chemotherapy treatment in adults or 60 – 90 minutes before you start the chemotherapy treatment in children and adolescents. Your doctor may ask you to take other medicines including a corticosteroid (such as dexamethasone) and a ‘5HT3 antagonist’ (such as ondansetron) for preventing nausea and vomiting. Check with your doctor or pharmacist if you are not sure.
