Since November 2005, U.S. Customs and Border Protection agents have seized prescription drugs that 40,000 Americans had ordered from Canada, Sen. Bill Nelson noted on Tuesday. The new policy, which takes effect Oct. 9, was announced in an e-mail from the Department of Homeland Security to congressional staff Monday, Nelson said.

Customs spokeswoman Lynn Hollinger confirmed the policy change Tuesday, saying the agency would no longer intercept the drugs or issue letters to postal carriers indicating it is illegal to import prescription medications. She said the policy change was due to political pressure from lawmakers and people who complained they were no longer receiving their medicine.

"It's a great victory, particularly for the senior citizens who are having difficulty making financial ends meet in a time in which, sadly, some senior citizens have to make a decision between buying their prescription drugs and buying their groceries," Nelson said.

The change means that the U.S. Food and Drug Administration will resume oversight of the importation of prescription drugs. Before Customs took over enforcement the FDA largely ignored the importation of small amounts of prescription drugs.
