Acemannan is a compound used to stimulate the immune system to be more effective in killing certain viruses (FeLV and FIV) and certain cancer cells (fibrosarcomas). Given orally or by injection. Contact your veterinarian if your pet experiences lack of appetite, diarrhea, depression, fainting, changes in heart rate, or pain at the injection site.

Form and Storage
Powder for reconstitution for injection and oral administration. Protect from light. Use within 4 hours of reconstituting.

Indications for Use
Assists in the treatment of immunosuppression caused by feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infections, and certain cancers.

General Information
FDA approved for use as part of the treatment for fibrosarcoma (a type of cancer) in dogs and cats. Other uses are without FDA approval. Available by prescription. It stimulates release of cytokines which then help the body kill the cancer cells and may help kill certain viruses also.
