FDA officials said new data show consumers are continuing to buy drugs from Internet outlets in an attempt to save money on expensive prescription drugs sold in the United States.

But the FDA said people don't need to take chances by buying prescription drugs from Internet sites, because low-cost generic versions are available in the United States.

"This finding also may be an indication that some consumers are likely buying foreign drugs this way to avoid getting a prescription from their doctor or health care professional, since many Web sites do not require a prescription," the government agency said.

Officials said consumers should be aware of safety concerns of drugs purchased from unregulated Internet sellers.
