An AstraZeneca spokesman said in a statement, "Seroquel is not approved for the treatment of PTSD or indicated for use as a sleep aid. Atypical antipsychotics, like many other medications, are often prescribed by mental-health professionals for indications beyond those set forth in the FDA-approved label. Like patients, we trust doctors to use their medical judgment to determine when it is appropriate to prescribe medications. Patient safety is a core priority for AstraZeneca, and we believe that Seroquel is a safe and effective medication when used as recommended in the prescribing information."
