Is the US one of only two nations that allow direct advertising of prescription drugs? 

The U.S. and New Zealand are the only two countries that allow direct advertising on prescription drugs, according to University of Wisconsin-Madison School of Pharmacy professor Dr. David Kreling, a pharmaceutical policy and marketing expert.

In the U.S., the Food and Drug Administration approves marketing of prescription drugs through the Federal Food, Drug and Cosmetic Act. The act also prohibits using false or misleading information in advertisements.

The FDA requires advertisements to present the statement on a drug’s side effects in a “clear, conspicuous, and neutral manner.”

Most countries prohibit direct advertising of pharmaceuticals because some available drugs aren’t tested enough to guard against rare but potentially severe side effects.

While the U.S. has never had a federal law banning direct advertising of prescription drugs, companies did not publicize prescription information through direct advertisements until the 1980s. Previously only doctors and pharmacists received that information.

U.S. Sen. Ron Johnson, R-Wis., made the claim April 21.
