Interaction Details
There were no interactions found between Lenalidomide and Ergot. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Ergot Overview
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.
Lenalidomide Overview
-
Lenalidomide is used to treat a certain type of myelodysplastic syndrome (a group of conditions in which the bone marrow produces blood cells that are misshapen and does not produce enough healthy blood cells). Lenalidomide is also used along with dexamethasone to treat people with multiple myeloma (a type of cancer of the bone marrow). It is also used to treat people with multiple myeloma after a hematopoietic stem-cell transplant (HSCT; procedure in which certain blood cells are removed from the body and then returned to the body). Lenalidomide is also used to treat people with mantle cell lymphoma (a fast-growing cancer that begins in the cells of the immune system) who have been treated with bortezomib (Velcade) and at least one other medication. Lenalidomide should not be used to treat people with chronic lymphocytic leukemia (a type of cancer of the white blood cells that gets worse slowly over time) unless they are participating in a clinical trial (research study to see whether a medication may be used safely and effectively to treat a certain condition). Lenalidomide is in a class of medications called immunomodulatory agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells in the bone marrow.
