Sen. Richard Blumenthal announced Tuesday new proposed legislation that would require medicine labels to include major food allergens.

About 93% of medications contain common food allergens like milk, eggs and nuts, officials say.

Blumenthal says companies are not required to disclose that information on their labels. He says allergens are found in Tylenol, Benadryl and Claritin.

"The kinds of reactions can be severe and even if they are not life-threatening, they can be avoided," says Blumenthal.

If the legislation passes, it will amend the Food Drug and Cosmetic Act to require such allergen warnings.
