In addition to the activities of regulatory agencies, pharmaceutical companies also have a responsibility to monitor the safety of their products. Companies are required to conduct clinical trials prior to the approval of a medication, and to continue monitoring the safety of the medication after it has been approved for use. If a problem is identified, the company is required to take appropriate action to minimize the risk to patients.
