Washington -- The U.S. Food and Drug Administration has announced a safety review of several drugs known as tumor necrosis factor, or TNF, blockers.
The agency said the drugs -- Enbrel, Humira and Remicade -- are being reviewed for a possible association with development of lymphoma and other cancers in children and young adults treated for juvenile idiopathic arthritis and Crohn's disease.
The drugs suppress the immune system by blocking the activity of TNF, a substance in the body that can cause inflammation and lead to immune system-related diseases.
The FDA said it has asked the makers of the TNF blockers to supply information about all cases of cancer reported in children and young adults taking TNF blockers.
While the review is ongoing, FDA advises doctors to weigh the possible association with lymphoma and other cancers against the benefits of treatment when prescribing TNF blockers to children and young adults.
Enbrel is manufactured by Amgen and Wyeth Pharmaceuticals, Humira is produced by Abbott Laboratories and Remicade is manufactured by Centocor Inc.

enbrel-Seizures
I started taking Enbrel back on October of 07. On December of 07, I passed out while driving and had a vehicle accident. On March of 08, Again I passed out and had another accident. At that time I was unaware of the seizures that I was having. I started with petit-mal seizures, then I started with the gran-mal seizures. I only took the medication for about three months. At this time, I am still being treated with medication.
The doctors should make it a point of mentioning to patients the worst possible side effects, as many of us trust our doctors and not consider them possible.
