1. What is Fosaprepitant Zentiva and what is it used for

Fosaprepitant Zentiva contains the active substance fosaprepitant which is converted into 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. Fosaprepitant Zentiva works by blocking the signals to this area, thereby reducing nausea and vomiting. Fosaprepitant Zentiva is used in adults, adolescents, and children from 6 months of age, in combination with other medicines,to prevent nausea and vomiting caused by a type of chemotherapy (cancer treatment) that induces strong or moderate nausea and vomiting.

2. What you need to know before you use Fosaprepitant Zentiva

Do not use Fosaprepitant Zentiva:

• if you are allergic to fosaprepitant, aprepitant, or polysorbate 80 or any of the other ingredients of this medicine (listed in section 6).
• with medicines that contain pimozide (used to treat psychiatric disorders), terfenadine, and astemizole (used for allergic rhinitis and other allergic disorders), cisapride (used to treat digestive problems). Inform your doctor if you are taking these medicines as the treatment should be modified before starting Fosaprepitant

Instructions for reconstitution and dilution of Fosaprepitant Zentiva 150 mg:

1. Inject 5 ml of sodium chloride 9 mg/ml (0.9%) injection solution into the vial. Ensure that the injection solution is added to the vial along the wall of the vial to avoid foaming. Gently rotate the vial. Avoid shaking and agitating the injection solution in the vial.
2. Prepare an infusion bag containing 145 mlof sodium chloride 9 mg/ml (0.9%) injection solution (e.g., by removing 105 ml of sodium chloride 9 mg/ml (0.9%) injection solution from a 250 ml infusion bag of sodium chloride 9 mg/ml (0.9%) injection solution).
3. Withdraw the entire volume from the vial and transfer it into the infusion bag containing 145 ml of sodium chloride 9 mg/ml (0.9%) injection solution to obtain a total volume of 150 ml and a final concentration of 1 mg/ml. Gently invert the bag 2-3 times (see ‘How to use Fosaprepitant Tillomed’).
4. Determine the volume to be administered from this prepared infusion bag, according to the recommended dose (see the Summary of Product Characteristics or Package Leaflet, section 4.2).

Adults

The entire volume of the prepared infusion bag should be administered (150 ml).

Pediatric population

In patients from 12 years of age, the volume to be administered is calculated as follows:

• The volume to be administered (ml) is equal to the recommended dose (mg)

In patients between 6 months and 12 years of age, the volume to be administered is calculated as follows:

• Volume to be administered (ml) = recommended dose (mg/kg) x weight (kg)

• Note: Do not exceed the maximum doses (see the Summary of Product Characteristics or Package Leaflet, section 4.2).

1. For volumes less than 150 ml, if necessary, the calculated volume can be transferred to a smaller bag or a syringe before administration by infusion.

The final reconstituted and diluted solution is stable for 24 hours at 25°C.

When the solution and packaging allow, a visual inspection of parenteral medicines should be performed before administration to check for particles or discoloration.

The appearance of the reconstituted solution is the same as the appearance of the diluent used.

Discard any remaining solution and residual material. The disposal of unused medicine and all materials that have come into contact with it should be carried out in accordance with local regulations.

The medicine should not be reconstituted or mixed with solutions for which physical and chemical compatibility has not been established (see the Summary of Product Characteristics or Package Leaflet, section 6.2).
