What Caspofungin is
Caspofungin contains a medicine called caspofungin. This belongs to a group of medicines called antifungals.
What Caspofungin is used for
Caspofungin is used to treat the following infections in children, adolescents and adults: serious fungal infections in your tissues or organs (called ‘invasive candidiasis'). This infection is caused by fungal (yeast) cells called Candida. People who might get this type of infection include those who have just had an operation or those whose immune systems are weak. Fever and chills that do not respond to an antibiotic are the most common signs of this type of infection
fungal infections in your nose, nasal sinuses or lungs (called ‘invasive aspergillosis') if other anti-fungal treatments have not worked or have caused side effects. This infection is caused by a mould called Aspergillus. People who might get this type of infection include those having chemotherapy, those who have had a transplant and those whose immune systems are weak
suspected fungal infections if you have a fever and a low white cell count that have not improved on treatment with an antibiotic. People who are at risk of getting a fungal infection include those who have just had an operation or those whose immune systems are weak.
How Caspofungin works
Caspofungin makes fungal cells fragile and stops the fungus from growing properly. This stops the infection from spreading and gives the body's natural defences a chance to completely get rid of the infection.
Do not use Caspofungin
if you are allergic to caspofungin or any of the other ingredients of this medicine (listed in section 6).
If you are not sure, talk to your doctor, pharmacist or nurse before you are given your medicine.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before you are given Caspofungin if: you are allergic to any other medicines
you have ever had liver problems - you might need a different dose of this medicine you are already taking ciclosporin (used to help prevent organ transplant rejection or to suppress your immune system) - as your doctor may need to run extra blood tests during your treatment
you have ever had any other medical problem.
If any of the above applies to you (or you are not sure), talk to your doctor, pharmacist or nurse before you are given Caspofungin.
Other medicines and Caspofungin
Please tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines. This includes medicines obtained without a prescription, including herbal medicines.
This is because Caspofungin can affect the way some other medicines work. Also some other medicines can affect the way Caspofungin works.
Tell your doctor, pharmacist or nurse if you are taking any of the following medicines:
• ciclosporin or tacrolimus (used to help prevent organ transplant rejection or to suppress your immune system) as your doctor may need to run extra blood tests during your treatment
• some HIV medicines such as efavirenz or nevirapine
• phenytoin or carbamazepine (used for the treatment of seizures)
• dexamethasone (a steroid)
• rifampicin (an antibiotic).
If any of the above apply to you (or you are not sure), talk to your doctor, pharmacist or nurse before you are given Caspofungin.

Instructions of how to reconstitute and dilute Caspofungin:
Reconstitution of Caspofungin
DO NOT USE ANY DILUENTS CONTAINING GLUCOSE, as Caspofungin is not stable in diluents containing glucose. DO NOT MIX OR CO-INFUSE CASPOFUNGIN WITH ANY OTHER MEDICINES, as there are no data available on the compatibility of Caspofungin with other intravenous substances, additives, or medicinal products. Visually inspect the infusion solution for particulate matter or discolouration.
Chemical and physical in-use stability of the reconstituted concentrate has been demonstrated for 24 hours at 25°C or less when reconstituted with water for injection.
Chemical and physical in-use stability of the diluted patient infusion solution has been demonstrated for 24 hours at 25°C and for 48 hours at (2 to 8°C) when diluted with sodium chloride solution 9 mg/ml (0.9 %), 4.5 mg/ml (0.45 %), or 2.25 mg/ml (0.225 %) for infusion, or lactated Ringer's solution.
From a microbiological point of view, the product should be used immediately. If not used mmediately, in use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2 to 8°C, unless reconstitution and dilution have taken place in controlled validated aseptic conditions.
Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
INSTRUCTIONS FOR USE IN ADULT PATIENTS Step 1 Reconstitution of conventional vials

INSTRUCTIONS FOR USE IN PAEDIATRIC PATIENTS Calculation of Body Surface Area (BSA) for paediatric dosing
Before preparation of infusion, calculate the body surface area (BSA) of the patient using the following formula: (Mosteller Formula)
Determine the actual loading dose to be used in the paediatric patient by using the patient's BSA (as calculated above) and the following equation:
BSA (m2) X 70 mg/m2 = Loading Dose
The maximum loading dose on Day 1 should not exceed 70 mg regardless of the patient's calculated dose.
Equilibrate the refrigerated vial of Caspofungin to room temperature.
Aseptically add 10.5 ml of water for injection3. This reconstituted solution may be stored for up to 24 hours at or below 25°C.b This will give a final caspofungin concentration in the vial of 5.2 mg/ml.
Remove the volume of medicinal product equal to the calculated loading dose (Step 1) from the vial. Aseptically transfer this volume (ml)c of reconstituted Caspofungin to an IV bag (or bottle) containing 250 ml of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection, or Lactated Ringers Injection. Alternatively, the volume (ml)c of reconstituted Caspofungin can be added to a reduced volume of 0.9 %, 0.45 %, or 0.225 %
Sodium Chloride Injection or Lactated Ringers Injection, not to exceed a final concentration of 0.5 mg/ml. This infusion solution must be used within 24 hours if stored at or below 25°C or within 48 hours if stored refrigerated at 2 to 8°C.
1. Determine the actual daily maintenance dose to be used in the paediatric patient by using the patient's BSA (as calculated above) and the following equation:
BSA (m2) X 50 mg/m2 = Daily Maintenance Dose
The daily maintenance dose should not exceed 70 mg regardless of the patient's calculated dose.
Equilibrate the refrigerated vial of Caspofungin to room temperature.
Aseptically add 10.5 ml of water for injection.a This reconstituted solution may be stored for up to 24 hours at or below 25°C.b This will give a final caspofungin concentration in the vial of 5.2 mg/ml.
Remove the volume of medicinal product equal to the calculated daily maintenance dose (Step 1) from the vial. Aseptically transfer this volume (ml)c of reconstituted Caspofungin to an IV bag (or bottle) containing 250 ml of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection, or Lactated Ringers Injection. Alternatively, the volume (ml)c of reconstituted Caspofungin can be added to a reduced volume of 0.9 %,
0.45 %, or 0.225 % Sodium Chloride Injection or Lactated Ringers Injection, not to exceed a final concentration of 0.5 mg/ml. This infusion solution must be used within 24 hours if stored at or below 25°C or within 48 hours if stored refrigerated at 2 to 8°C.
a. The white to off-white colour powder will dissolve completely. Mix gently until a clear solution is obtained.
b. Visually inspect the reconstituted solution for particulate matter or discolouration during reconstitution and prior to infusion. Do not use if the solution is cloudy or has precipitated.
c. Caspofungin is formulated to provide the full labeled vial dose (50 mg) when 10 ml is withdrawn from the vial.
