VA hospitals across the country are refusing to allow new prescription drug approvals for a variety of reasons.
Some hospitals say they have found no significant evidence that the drugs work.
Others say the drugs are too expensive or require too much research and development.
But for some, they’re simply rejecting the medication because it’s not working.
The VA, the federal government’s largest health insurer, is not the only agency to face questions about the efficacy of a drug.
Hospitals are also facing questions about whether their use of drugs to treat certain cancers is medically justified.
Some are not only rejecting the medications, they are also refusing to provide them.
Some are refusing the drugs in large part because the drugs do not work, say doctors and patients who have spoken out.
But others are rejecting the drugs because the drug has been approved but it has not been tested or proven effective.
The agency has a long history of rejecting medications to treat cancer and other diseases.
It approved a drug for a rare genetic condition called cystic fibrosis, which affects the lungs, in 2006.
In 2011, the agency denied another drug for treating Crohn’s disease, the most common cause of gastrointestinal problems.
In 2015, the VA said it was delaying a drug used to treat multiple sclerosis because it was not effective.
The agency said in 2014 that it had approved a new drug to treat a rare disease called primary myeloid leukemia, which was not proven to be cancer-causing.
The drugs approved for cancer patients are also not effective for other diseases, including diabetes.
The most recent controversy over the VA’s use of chemotherapy drugs was over an approval for a new cancer drug called TNF-alpha.
The drug is used to help fight cancerous cells in the blood and in bone marrow.
In a recent letter, the department said TNFalpha did not work for cancer.
The letter was dated June 12, just weeks after the agency’s rejection of TNFbeta, a drug that was approved in 2014.TNFalpha was a new treatment that was developed by the company BioNTech that is being marketed under a different brand name, TNFα.
BioNTec had already received approval to sell TNFAlpha as a cancer treatment.
It is the first drug approved by the FDA to treat primary myematic leukemia.
The U.S. Food and Drug Administration is not reviewing the approval for TNFBeta, which is being developed by a separate company.
But the agency did issue an opinion in March that said the drug is not effective against the most commonly treated forms of myelodysplastic syndrome, a genetic disorder that causes painful and sometimes deadly bone marrow cell changes in bone cells.
The FDA said the drugs have not been shown to be safe for treatment of the disorder.
Teflon has long been used in hospitals for disinfection, and some doctors and nurses say they believe the drugs also may be harmful.
Some have said the use of Teflon in hospitals and nursing homes is unnecessary and could cause harm to patients.
Some health care workers say that despite what they are hearing from doctors and nursing home administrators, the drugs can work.
“When you see that you’re being told by your supervisor to go to the hospital, you feel like you’re dying,” said Dr. Roberta Wainstein, the president of the American College of Nurse-Midwives.
“That is not going to happen.”
Dr. Wainstin is also concerned about what could happen if a patient takes the drug for other reasons.
“They might decide they want to go back home and try to get chemotherapy again,” she said.
“It is not really safe to go into a nursing home and be told to stay there and not go back.”
The department has not publicly commented on the issue.
