The association has sponsored a campaign to alert parents on how best to use the medications, including public-service announcements, social-media efforts and brochures for family physicians to distribute to parents. Representatives of the industry group also said it can be challenging to design, and enroll participants for, studies testing medicines for children's colds.

该协会赞助了一项通过公益广告、社交媒体和发放宣传册（让家庭医生将宣传册发放给家长）等方式提醒家长如何更好地用药的活动。该协会代表还表示，检验儿童感冒药安全性的研究设计起来有难度，招募实验对象也有难度。

Pfizer said it 'encourages all parents to read and follow the label of any children's medication to determine appropriate use and dose.' A spokeswoman for Novartis said it declined to comment.

辉瑞公司称，该公司“鼓励所有家长阅读每一种儿童药品的标签，并遵照标签说明确定合适的用法和剂量”。诺华公司一名发言人称，该公司就此不予置评。

An FDA spokeswoman said the agency 'supports efforts. . .to better inform consumers about the safe and effective use of these products' and has worked with the Centers for Disease Control and Prevention on the issue.

FDA一名发言人称，该机构“支持相关方面为此做出的努力……以使消费者更好地了解如何安全有效地使用这些产品”，并与美国疾病控制与预防中心(Centers for Disease Control and Prevention)就此进行了合作。
