WHY is this medicine prescribed?
Velmanase alfa is used to treat certain symptoms associated with alpha-mannosidosis (a genetic condition where the body is unable to break down complex sugars). Velmanase alfa is in a class of medications called recombinant lysosomal enzymes. It works by breaking down mannose-containing oligosaccharides, a complex sugar, that can build up in people with alpha-mannosidosis and cause toxicity to many of the body's tissues.
HOW should this medicine be used?
Velmanase alfa comes as a powder to be mixed with water and administered intravenously (into the vein) by a doctor or a nurse at a healthcare facility. It is usually given every week.
Velmanase alfa controls symptoms associated with alpha-mannosidosis but does not cure it. Continue to show up for your scheduled infusion appointments unless your doctor tells you not to.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
