How do I take/use this medicine?
Take Olanzapine exactly as directed by your doctor. Do not take more or less than instructed by your doctor.
Olanzapine is available as a coated tablet, an orodispersible (orally disintegrating) tablet or as wafers.
If you have been given the coated tablet, swallow it whole with a glass of water.
If you have been given the orodispersible tablet, remove it from the foil only just before you take it. Place it directly in your mouth. It will dissolve quickly. Swallow it once it has dissolved in your mouth. You can also dissolve it in a glass of water, juice (orange or apple), milk or coffee just before you want to take it. Drink it immediately once the tablet has dissolved completely. The orodispersible tablet is easily broken. Handle it gently. Do not touch the tablet with wet hands.
If you have been given the wafer, remove it from the foil only just before you take it. Place it directly on the tongue. Allow it to dissolve and swallow it with your saliva. The wafer is easily broken. Handle it gently. Do not touch the wafer with wet hands.
Olanzapine may be taken with or without food. Try to take it at the same time everyday.
You may need to take Olanzapine for some time before the full benefits can be felt. Do not be discouraged if you do not feel better soon after taking the medicine. Olanzapine must be taken regularly for it to work well.
Do not stop taking Olanzapine unless instructed by your doctor. You may feel unwell if Olanzapine is stopped suddenly. When your doctor decides that you do not need Olanzapine anymore, he will usually reduce your dose slowly. Follow the doctor's instructions carefully.
