The one exception is California's Proposition 65, which requires warnings on labels of products containing carcinogens. Prop 65 was "grandfathered," meaning it remains fully in effect.

Provisions of the newly passed FDA modernization law guarantee one national system of regulation for OTC drugs, including labeling requirements. The law prohibits states from imposing different or additional requirements from those of FDA.
