Why It Matters

Schizophrenia is a chronic and disabling psychiatric disorder that requires ongoing treatment and monitoring. Symptoms include hallucinations, illogical thinking, memory impairment and incoherent speech.1 Medication nonadherence is common and a major concern in the treatment of schizophrenia. Using antipsychotic medications as prescribed reduces the risk of relapse or hospitalization.2
