INTERACTIONS WITH THIS MEDICATION
Tell all doctors, dentists and pharmacists who are treating you that you are taking Teva-Olanzapine.
Tell your doctor or pharmacist that you are taking Teva-Olanzapine before you start taking any new medicines.
A combination of Teva-Olanzapine 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 Teva-Olanzapine. It is recommended that you DO NOT drink alcohol while taking Teva-Olanzapine.
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 Teva-Olanzapine in your blood, making Teva-Olanzapine less effective.
Only take other medicines while you are on Teva-Olanzapine if your doctor tells you that you can. DO NOT give Teva-Olanzapine 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 Teva-Olanzapine 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 Teva-Olanzapine 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 Teva-Olanzapine, even after your symptoms have improved or disappeared. Teva-Olanzapine should be taken for as long as you and your doctor believe it is helping you.
Proper Handling Instructions
Teva-Olanzapine Tablets:
Teva-Olanzapine tablets should be swallowed whole
with a glass of water. Teva-Olanzapine tablets can be taken with or without food.
Overdose:
If you think you have taken too much Teva-Olanzapine, contact your healthcare professional, hospital emergency department or regional poison control centre immediately, even if there are no symptoms.
Show the health care professional 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 Teva-Olanzapine are drowsiness and slurred speech.
Missed Dose:
Take your prescribed dose at the same time each day. If you miss a dose of Teva-Olanzapine 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, Teva-Olanzapine 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 oral Teva-Olanzapine are:
- drowsiness
- weight gain
- dizziness
- increased appetite
- fluid retention
- constipation
- dry mouth

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 Teva-Olanzapine 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 Teva-Olanzapine 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 Teva-Olanzapine and continue to monitor it for as long as you are being treated.
Your doctor should take blood tests before starting Teva-Olanzapine. They will monitor blood sugar, and the number of 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.
