Interactions with this medication

Tell all doctors, dentists and pharmacists who are treating you that you are taking OLANZAPINE ODT.

Tell your doctor or pharmacist that you are taking OLANZAPINE ODT before you start taking any new medicines.

A combination of OLANZAPINE ODT with the following medicines might make you feel drowsy:

  • medicines taken for anxiety or to help you sleep
  • medicines taken for depression.

The effects of alcohol could be made worse while taking OLANZAPINE ODT. It is recommended that you DO NOT drink alcohol while taking OLANZAPINE ODT.

You should tell your doctor if you are taking fluvoxamine (antidepressant), ketoconazole (antifungal) or ciprofloxacin (antibiotic), as these medicines may lead to higher concentrations of olanzapine in your blood.

You should also tell your doctor if you are taking carbamazepine as it may lead to lower concentrations of OLANZAPINE ODT in your blood, making OLANZAPINE ODT less effective.

Only take other medicines while you are on OLANZAPINE ODT if your doctor tells you that you can. DO NOT give OLANZAPINE ODT to anyone else. Your doctor has prescribed it for you and your condition.

Proper use of this medication

Usual Dose

The most important thing about taking 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 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 ODT, even after your symptoms have improved or disappeared. OLANZAPINE ODT should be taken for as long as you and your doctor believe it is helping you.

Proper Handling Instructions:
OLANZAPINE ODT: Follow the instructions below:

  1. Gently push the tablet out from the blister.
  2. 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.

Overdose

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 box or 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 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 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.

Side effects and what to do about them

Like other medicines, OLANZAPINE ODT can cause some side effects. These side effects are most likely to be minor and temporary. However, some may be serious and need medical attention. Many of the side effects are dose related, so it is important not to exceed your prescribed dose. The most common side effects of OLANZAPINE ODT are:

  • drowsiness
  • weight gain
  • dizziness
  • increased appetite
  • fluid retention
  • constipation
  • dry mouth
  • feeling of restlessness (akathisia)
  • decreased blood pressure upon rising from a lying or sitting position.

Events of stuttering (disruptive speech) and increased salivation (salivary hypersecretion) were uncommonly reported. You should also tell your doctor if you notice any symptoms that worry you, even if you think the problems are not connected with the medicine or are not listed here.

Because some people experience drowsiness, you should avoid driving a car or operating machinery until you know how OLANZAPINE ODT affects you. Some people may feel dizzy in the early stages of treatment, especially when getting up from a lying or sitting position. This side effect usually passes after taking OLANZAPINE ODT for a few days.

After prolonged use in women, medicines of this type can cause milk secretion or changes in the regularity of their monthly period. On rare occasions, after prolonged use in men, medicines of this type have been associated with breast enlargement. As well, abnormal liver function tests have been reported on occasion.

Your doctor should check your body weight before starting OLANZAPINE ODT and continue to monitor it for as long as you are being treated.

Your doctor should take blood tests before starting OLANZAPINE ODT. They will monitor blood sugar, and the number of leucocytes (infection fighting white blood cells). Your doctor should continue to monitor your blood for as long as you are being treated.

If you have high levels of prolactin (measured with a blood test) and a condition called hypogonadism you may be at increased risk of breaking a bone due to osteoporosis. This occurs in both men and women.

Do not be alarmed by this list of possible side effects. You may not experience any of them. If any of these side effects are experienced, they are usually mild and temporary.

The following table is based on data from placebo-controlled clinical trials and from post-marketing data.
