There are three phases of clinical trials that are used to assess the safety and efficacy of medications. These three phases take years to complete. Occasionally the FDA will mandate postmarketing survallence (phase 4) in order to detect rare or long term risks. Additionally the FDA has the MedWatch Program which allows health care professionals to report and monitor side effects and problems.
