The court in Lopez responded to a similar situation where LOPEZ SUEd DrugsRUS because it advertised one of its drugs by saying " a single pill tonight Eliminates the need for five tomorrow . " In reliance on the advertisement , MS . Lopez stopped taking her five arthritis pills and began taking the single pill touted by DrugsRus . As a result of the change in her medications , MS . Lopez is no longer able to maintain regular employment . The court determined that the rule of law that applied in this instance is the reasonable person standard . The key issue with respect to this standard is , " Would the reasonable person have believed that one tablet for arthritis could adequately replace five ?" THE
