Proper use of this medication

Usual dose

The most important thing about taking OLANZAPINE or OLANZAPINE ODT is to take it the way your doctor has prescribed - the right dose, every day. Your doctor has decided on the best dosage for you based on your individual situation and needs. Your doctor may increase or decrease your dose depending on your response.

Although OLANZAPINE and OLANZAPINE ODT cannot cure your condition, it can help relieve your symptoms. If your symptoms improve or disappear, it is probably because your treatment is working. Studies have shown that, after coming off medication, a relapse of symptoms occurs in about 2 out of 3 patients and is more than double that of patients staying on their medication. That is why it is so important to keep taking OLANZAPINE or OLANZAPINE ODT, even after your symptoms have improved or disappeared. OLANZAPINE and OLANZAPINE ODT should be taken for as long as you and your doctor believe it is helping you.

Proper Handling Instructions
OLANZAPINE tablets should be swallowed whole with a glass of water. OLANZAPINE tablets can be taken with or without food.

OLANZAPINE ODT orally disintegrating tablets:
OLANZAPINE ODT orally disintegrating tablets should be handled carefully with dry hands.

Follow the instructions below:

  1. Separate one blister cell from the strip by tearing along the dotted line.
  2. Carefully peel off the backing foil.
  3. Gently push the tablet out from the bottom of the blister.
  4. Avoid touching the tablet with your hands. Put the tablet directly into your mouth. It will begin to dissolve in your mouth within a few seconds. You can also place the tablet directly into a full glass of water, milk, coffee, orange juice or apple juice. Stir and drink all of the contents immediately.


In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Show the health care practitioner your bottle of tablets. Do this even if there are no signs of discomfort or poisoning. The most common signs if you have taken too much OLANZAPINE or OLANZAPINE ODT are drowsiness and slurred speech.

Missed Dose

Take your prescribed dose at the same time each day. If you miss a dose of OLANZAPINE or OLANZAPINE ODT by a few hours, take the dose when you remember. If most of the day has passed, wait until your next scheduled dose and try not to miss any more. Do not take 2 doses at once.
