Ergot Overview

Ergot Ergot is a fungal plant infection that most commonly grows on rye. Ergot contains ergolines, which are alkaloids that have various pharmacologic and toxic effects. A well-known illness from the Middle Ages, St. Anthony's Fire, was brought on by the widespread consumption of fungus-contaminated rye grain which caused ergot poisoning (ergotism). Ergot has been used medicinally for obstetric and gynecologic conditions, such as abnormally heavy bleeding at menstruation since ergot contains chemicals that can help reduce bleeding by causing a narrowing of the blood vessels. Due to the safety concerns of consuming ergot, its use is not recommended.

Filgrastim Overview

  • Filgrastim injection products (Granix, Neupogen, Nivestym, Releuko, Zarxio) are used to decrease the chance of infection in people who have non myeloid cancer (cancer that does not involve the bone marrow) and are receiving chemotherapy medications that may decrease the number of neutrophils (a type of blood cell needed to fight infection). Filgrastim injection products (Neupogen, Nivestym, Releuko, Zarxio) are also used to help increase the number of white blood cells, and decrease the length of time with fever in people with acute myeloid leukemia (AML; a type of cancer of the white blood cells) who are receiving treatment with chemotherapy medications. Filgrastim injection products (Neupogen, Nivestym, Releuko, Zarxio) are also used in people who are undergoing bone marrow transplants and in people who have severe chronic neutropenia (condition in which there are a low number of neutrophils in the blood). Filgrastim injection products (Neupogen, Nivestym, Zarxio) are also used to prepare the blood for leukapheresis (a treatment in which certain blood cells are removed from the body. Filgrastim injection (Neupogen) is also used to increase the chance of survival in people who have been exposed to harmful amounts of radiation, which can cause severe and life-threatening damage to your bone marrow. Filgrastim is in a class of medications called colony-stimulating factors. It works by helping the body make more neutrophils.
