Zyprexa

Brand name: Oliza
Generic name: Oliza - OLIZA (Olanzapine, Zyprexa)
Why is Oliza prescribed?

Oliza helps manage symptoms of schizophrenia, the manic phase of bipolar disorder, and other psychotic disorders. It is thought to work by opposing the action of serotonin and dopamine, two of the brain's major chemical messengers. The drug is available as Oliza tablets and Oliza Zydis, which dissolves rapidly with or without liquid.
Most important fact about Oliza without prescriptions

At the start of Oliza therapy, the drug can cause extreme low blood pressure, increased heart rate, dizziness, and, in rare cases, a tendency to faint when first standing up. These problems are more likely if you are dehydrated, have heart disease, or take blood pressure medicine. To avoid such problems, your doctor may start with a low dose of Oliza and increase the dosage gradually.
How should you take Oliza?

Oliza should be taken once a day with or without food. To use Oliza Zydis, open the sachet, peel back the foil on the blister pack, remove the tablet, and place the entire tablet in the mouth. Do not push the tablet through the foil. The medication can be taken with or without water; the saliva in your mouth will cause the tablet to dissolve.

If you miss a dose...

Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at once.

-- Storage instructions --

Store at room temperature away from light and moisture.
