Schizophrenia Home > Zyprexa Dosage

The recommended starting dosage of Zyprexa for adults with schizophrenia is 5 mg to 10 mg once daily. For the treatment of bipolar disorder, the recommended starting dose is 10 mg to 15 mg once daily. With either condition, the maximum dose of Zyprexa is 20 mg a day. Your age and other medical conditions you may have are among the factors that can affect the amount you are prescribed.

An Introduction to Zyprexa Dosing

The dose of Zyprexa® (olanzapine) your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • The medical condition being treated
  • Your age
  • The severity of your condition
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As always, do not adjust this amount unless your healthcare provider specifically tells you to do so.
 

Dosage of Zyprexa for Schizophrenia

The recommended starting oral Zyprexa dose for adults with schizophrenia is 5 mg to 10 mg once daily. If you start at less than Zyprexa 10 mg daily, your healthcare provider may increase the dosage to 10 mg within the first few days.
 
The recommended starting oral Zyprexa dose for adolescents (age 13 to 17) with schizophrenia is 2.5 to 5 mg once daily, with a target dose of 10 mg per day (although higher doses may sometimes be necessary).
 
After that, your healthcare provider may choose to increase the dosage further if symptoms continue, or decrease the dose if side effects occur. The maximum recommended dose for Zyprexa is 20 mg per day.
