    Customer Service Hours

    Monday through Friday, 7:30 am to 4:30 pm CST.

    Customer Support Services are available to assist you with billing, credit, returns and shipment schedule inquiries and procedures.

    Concealed Shipment Damage/Losses

    Damage/loss claims must be documented upon delivery and reported directly to Mallinckrodt’s Customer Service Group at 800.325.8888 within 10 days of purchase. The U.S. Drug Enforcement Administration recommends that all customers open and inventory all shipments as soon as possible. Failure to report these damages/Iosses in a timely manner significantly impairs Mallinckrodt’s ability to properly investigate the cause of the damage or loss. Any damage or loss reported to Mallinckrodt more than 10 days after receipt by the customer will not be eligible for credit.
