Expert medication care
Specialized support for clozapine treatment
The Massachusetts General Hospital Clozapine Clinic evaluates and provides psychiatric medication treatment for adults with psychotic illness who are taking clozapine or are interested in considering a clozapine trial.
Clozapine is an antipsychotic medication used when schizophrenia symptoms have not improved adequately with other antipsychotic medications. For an appropriate patient, it can provide meaningful symptom relief, but it requires careful medical follow-up because potentially serious side effects can occur.

Understanding the treatment
Why clozapine may be considered
Clozapine is an effective antipsychotic medication for treatment-resistant schizophrenia. It may be considered when symptoms have not improved adequately after sequential treatment with two other antipsychotic medications.
Specialized expertise
Starting and managing clozapine safely requires clinical experience and careful follow-up. The clinic's clinicians have years of experience helping patients begin and continue this treatment.
What regular monitoring means
Monitoring includes scheduled blood tests and clinical visits to assess treatment response, possible side effects, vital signs, weight and metabolic health. The frequency and type of monitoring may change over time and are individualized by the care team.
Treatment decisions are individualized. An evaluation with a qualified clinician is needed to determine whether clozapine is appropriate for a particular patient.
A careful, individualized process
What to expect
The clinic reviews each person's diagnosis, symptoms, previous medication trials, current treatment and medical history. The team then discusses whether clozapine care through the clinic is clinically appropriate and what next steps may involve.
- 1Clinical evaluation
Review your treatment history, current symptoms and goals for care.
- 2Shared treatment planning
Discuss potential benefits, risks, monitoring requirements and alternatives.
- 3Specialized follow-up
If treatment through the clinic is appropriate, develop a plan for medication management and ongoing monitoring.
