Patient’s DNA May Be Signal to Tailor Medication - Experts say that most drugs work for only about

half the people who take them.

For more than two years, Jody Uslan had been taking the drug tamoxifen in hopes of preventing a recurrence of breast cancer. Then a new test suggested that because of her genetic makeup, the drug was not doing her any good.

“I was devastated,” said Ms. Uslan, 52, who stopped taking tamoxifen and is now evaluating alternative treatments. “You find out you’ve been taking this medication for all of this time, and find out you are not getting benefit.”

Ms. Uslan’s situation is all too common — and not just among the hundreds of thousands of women in this country taking tamoxifen.

Experts say that most drugs, whatever the disease, work for only about half the people who take them. Not only is much of the nation’s approximately $300 billion annual drug spending wasted, but countless patients are being exposed unnecessarily to side effects.

I'm not saying it's not a valuable medical technique.

Are there laws requiring the destruction of such biologicals and DNA test results or abstractions obtained from them, or are those required to be kept in The Authoritarians' files?

for their patients going through menopause. They do saliva testing to find out exactly what the women needs and go from there. Very customized medicine. Frankly, I think customized medicine is the way to go.
