H5N1 influenza is sometimes called avian flu or "bird flu" because it is usually found in birds, including domestic poultry such as chickens and geese. You cannot become infected with H5N1 influenza from eating fully cooked poultry products.

Influenza A subtype H5N1 is caused by a virus, and this virus affects mainly birds in Asia and Africa. Human infection with H5N1 influenza is rare, but you can become infected by having direct contact with sick or dead birds that have been infected with H5N1 influenza virus. You may also come into contact with H5N1 influenza virus if you visit a live poultry market.

Although H5N1 influenza virus is not easily transmitted from person to person, you can become infected if you have prolonged close contact with another person who has become infected with avian flu.

Influenza Virus Vaccine, H5N1 is used to help prevent disease in people who are at risk of coming into contact with infected birds or other sources of the virus.

Influenza Virus Vaccine, H5N1 is for use in adults and children who are at least 6 months old.

Influenza Virus Vaccine, H5N1 works by exposing you to a small dose of the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Like any vaccine, the H5N1 influenza virus vaccine may not provide protection from disease in every person.

Folate is a form of B vitamin that occurs naturally in many foods. Folic acid is the man-made form of folate that is added to processed foods or vitamin and mineral supplements. Folate is needed in the human body for production of red blood cells.

A lack (deficiency) of folate in the human body can be caused by certain diseases, by taking certain medications, or by not getting enough folate in your diet. Folate deficiency can lead to decreased red blood cells, or anemia. Folate deficiency can also cause high levels of a certain amino acid in the blood, a condition called hyperhomocysteinemia (HYE-per-HOE-moe-sis-tin-EE-mee-a).

XaQuil XR is a medical food for use in people who have conditions related to folate deficiency. This medicine is also used in people with major depressive disorder who have folate deficiency, or in people with schizophrenia who have hyperhomocysteinemia related to folate deficiency.

XaQuil XR is not an antidepressant or anti-psychotic medication. However, this medicine may enhance the effects of antidepressant medications.

XaQuil XR may also be used for purposes not listed in this medication guide.
