About Cancidas

Overview

Cancidas (caspofungin acetate) is an echinocandin antifungal supplied in a vial for intravenous infusion. It is used in adults and children aged 3 months and older for suspected fungal infections in patients with fever and low neutrophil counts, and for Candida infections of the bloodstream, esophagus, abdomen or space around the lungs. It also treats invasive aspergillosis when other treatments have not worked or cannot be tolerated. It works by blocking production of a substance needed to build fungal cell walls.

What it treats

- Suspected fungal infections in adults and children aged 3 months and older who have a fever and low neutrophil counts. - Candida bloodstream infections (candidemia), abscesses within the abdomen, peritonitis, and infections in the space around the lungs. - Candida infection of the esophagus (esophageal candidiasis). - Invasive aspergillosis when other treatments have not worked or cannot be tolerated. These uses apply to adults and children aged 3 months and older.

Safety information

Side effects

Common side effects in adults include diarrhea, fever, increased liver enzyme levels and low blood potassium. In children, common side effects include fever, diarrhea, rash, increased liver enzyme levels, low blood potassium, low blood pressure and chills. Serious allergic reactions, including anaphylaxis, have been reported. Seek immediate medical help for facial swelling, difficulty breathing, or a rash with itching or a feeling of warmth. Cancidas must be stopped at the first sign of an allergic reaction. Severe skin reactions, including Stevens–Johnson syndrome and toxic epidermal necrolysis, have also been reported and require urgent medical attention. Liver problems, including hepatitis and liver failure, have been reported. Contact your doctor if tests show abnormal liver enzymes; monitoring is needed to check for worsening liver function. Using Cancidas with cyclosporine can also increase liver enzymes and requires careful monitoring if liver tests become abnormal.

When to call your doctor

• Seek medical attention immediately for swelling of the face or swelling beneath the skin. • Seek medical attention immediately for trouble breathing or wheezing. • Seek medical attention immediately for a rash, itching or a sudden feeling of warmth, which may signal an allergic reaction.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

Do not use Cancidas if you have a known allergy to caspofungin acetate or any other ingredient in the product. Serious allergic reactions and severe skin reactions, including Stevens–Johnson syndrome and toxic epidermal necrolysis, have been reported. Treatment must be stopped at the first sign of an allergic reaction, with appropriate medical treatment given. Signs may include rash, itching, facial swelling, a feeling of warmth or breathing difficulties. Cancidas can cause abnormal liver enzyme levels. Cases of liver dysfunction, hepatitis and liver failure have been reported. People who develop abnormal liver tests need monitoring for worsening liver function and a review of whether treatment should continue. Adults with moderate liver impairment require a dose adjustment by the prescriber. No data are available for adults with severe liver impairment or children with any degree of liver impairment. Use with cyclosporine requires caution because liver enzymes may rise. This combination should be used only when the potential benefit outweighs the risk, with monitoring if liver tests become abnormal. Based on animal data, Cancidas may harm an unborn baby. Safety and effectiveness have not been established in infants younger than 3 months.
