What CASPOFUNGIN MYX is used for
Caspofungin MYX is used to treat the following fungal infections:
- Invasive candidiasis, including candidaemia
- Oesophageal candidiasis
- Invasive aspergillosis, when other antifungal treatments have not worked or when other antifungal treatments have not been tolerated.
Also, your doctor may suspect that you have a fungal infection in the following situation, and prescribe Caspofungin MYX to treat it.
- Chemotherapy or other medical treatments or conditions can lower the body's resistance to disease by lowering counts of certain white blood cells. If you have persistent fever following chemotherapy or under other conditions as noted above, and your fever is not reduced by treatment with an antibiotic, you may have a fungal infection.
Candidiasis is an infection caused by a fungus (yeast) called candida. Invasive candidiasis is a serious type of candidiasis which occurs in your bloodstream (referred to as candidaemia), or in tissues or organs such as the lining of the abdomen (peritonitis), the heart, kidneys, liver, bones, muscles, joints, spleen, or eyes.
Candidiasis can also occur in your food pipe, also known as the oesophagus (oesophageal candidiasis). It may cause difficulty or pain when swallowing.
Invasive aspergillosis is an infection caused by a fungus, called aspergillus (as-pur-jilus). Most of these infections begin in the respiratory tract (in the nose, sinuses, or lungs) because the spores of the fungus are usually present in the air we breathe. The spores are harmless in most healthy people due to the body's natural ability to fight disease.
However, invasive aspergillosis can be serious in certain circumstances as it can spread to other tissues and organs. Groups of people who are at increased risk of invasive aspergillosis include those who have poor immune systems, such as people with organ transplants, certain cancers and HIV/AIDS.
How CASPOFUNGIN MYX works
Caspofungin MYX belongs to a group of medicines called echinocandins.
It works by interfering with the production of a component of the fungal cell wall that is necessary for the fungus to continue living and growing. Fungal cells exposed to Caspofungin MYX have incomplete or defective cell walls, making them fragile and unable to grow.
Your doctor may have prescribed Caspofungin MYX for another reason.
Ask your doctor if you have any questions about why Caspofungin MYX has been prescribed for you.
The safety and effectiveness of Caspofungin MYX in children or teenagers younger than 18 years of age have not been established.
