What this is

Clozapine is a atypical antipsychotic given by the oral route. It's typically used in the antipsychotic category.

What the numbers mean

After one oral dose you'd typically start noticing the effect in 7 days – 2 weeks. The drug reaches its highest blood level in about 2.5 hr, and a single dose usually keeps working for around 12 hr.

Practical tips

Take consistently — the full benefit builds over time, not from a single dose. Swallow with water; check the label for food restrictions.
