INTERACTIONS WITH THIS MEDICATION
Tell all doctors, dentists and pharmacists who are treating you that you are taking OLANZAPINE.
Tell your doctor or pharmacist that you are taking OLANZAPINE before you start taking any new medicines.
A combination of 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 OLANZAPINE. It is recommended that you DO NOT drink alcohol while taking 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 OLANZAPINE in your blood, making OLANZAPINE less effective.
Only take other medicines while you are on OLANZAPINE if your doctor tells you that you can. DO NOT give 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 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 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 OLANZAPINE, even after your symptoms have improved or disappeared. OLANZAPINE should be taken for as long as you and your doctor believe it is helping you. Proper Handling Instructions
OLANZAPINE Tablets:
OLANZAPINE tablets should be swallowed whole with a glass of water. OLANZAPINE tablets can be taken with or without food.
Overdose:
If you take too much, immediately contact your doctor or go to your nearest hospital emergency department. Show the doctor 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 are drowsiness and slurred speech.
Missed Dose:
Take your prescribed dose at the same time each day. If you miss a dose of 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, 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 OLANZAPINE are:
- drowsiness
- weight gain
- dizziness
- increased appetite
- fluid retention
- constipation
- dry mouth
- a feeling of restlessness (akathisia)
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 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 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 and on rare occasion breast enlargement in men. Abnormal liver function tests have also been reported on occasion.
Do not be alarmed by this list of side effects, you may not experience any of them. If any of these side effects are experienced, they are usually mild and temporary.
