The magazine Mother Jones reports that a European company that makes an emergency contraceptive identical to the morning-after Plan B pill is set to warn consumers.
The European drug, Norlevo, will include a pamphlet stating the drug is completely ineffective for women over 176 pounds, and begins to lose effectiveness after 165 pounds.
ABC News has reached out to three U.S. manufacturers of the drug, who say they do not plan to issue a similar warning at this time.
