How soon after starting Zyprexa Relprevv will my symptoms improve?

It may take several weeks before you see the full effects of Zyprexa Relprevv (olanzapine), a prescription injection for the treatment of schizophrenia. In one clinical trial, patients experienced benefits by the two-week mark but continued to improve throughout the eight weeks of the study. Talk to your doctor if your symptoms are not getting better or if they get worse. You should also call your doctor if you have new symptoms, especially if you are feeling discouraged or out of control or feel that you may do harm to yourself or someone else.
