Caspofungin belongs to a group of medicines called antifungals.

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.

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.

• 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, nurse or pharmacist before you are given your medicine.

Talk to your doctor, nurse or pharmacist 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 cyclosporin (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.
• if 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, nurse or pharmacist before you are given Caspofungin.

Caspofungin may also cause Serious Cutaneous Adverse Reactions such as Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN).

Tell your doctor, nurse or pharmacist 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, nurse or pharmacist if you are taking any of the following medicines:

• cyclosporin 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, nurse or pharmacist before you are given Caspofungin.

Ask your doctor for advice before taking any medicine, if you are pregnant or breast-feeding or think you are pregnant.

• Caspofungin has not been studied in pregnant women. It should be used in pregnancy only if the potential benefit justifies the potential risk to the unborn baby.
• Women given Caspofungin should not breast-feed.

There is no information to suggest that Caspofungin affects your ability to drive or operate machinery.

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

The dose for children and adolescents may differ from the adult dose.

Your doctor will decide how much Caspofungin you need and for how long each day. If you are worried that you may have been given too much of this medicine, tell your doctor or nurse straight away.

• rash, itching, feeling warm, swelling of your face, lips or throat or difficulty breathing - you may be having a histamine reaction to the medicine.
• difficulty breathing with wheezing or a rash that gets worse - you may be having an allergic reaction to the medicine.
• cough, serious breathing difficulties - if you are an adult and have invasive aspergillosis you may be experiencing a serious respiratory problem that could result in respiratory failure.
