What happens if I miss a dose (Zyprexa, Zyprexa Zydis)?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Zyprexa, Zyprexa Zydis)?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include drowsiness, agitation, aggression, slurred speech, confusion, increased heart rate, jerky or uncontrolled muscle movements, trouble breathing, or fainting.

What should I avoid while taking olanzapine (Zyprexa, Zyprexa Zydis)?

Olanzapine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Drinking alcohol can increase sleepiness caused by olanzapine.

Avoid becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking olanzapine.

What other drugs will affect olanzapine (Zyprexa, Zyprexa Zydis)?

Before using olanzapine, tell your doctor if you regularly use other medicines that can make you sleepy or slow your breathing (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to the side effects of olanzapine.

Tell your doctor about all other medicines you use, especially:

• heart or blood pressure medication;
• carbamazepine (Carbatrol, Tegretol);
• diazepam (Valium);
• fluoxetine and olanzapine (Symbyax);
• fluvoxamine (Luvox);
• omeprazole (Prilosec);
• rifampin (Rifater, Rifadin, Rifamate); or
• a medication to treat Parkinson's disease including levodopa (Sinemet, Larodopa, Atamet), selegiline (Eldepryl, Emsam, Zelapar), pramipexole (Mirapex), ropinirole (Requip), and others.

This list is not complete and other drugs may interact with olanzapine. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

Where can I get more information?

Your pharmacist can provide more information about olanzapine.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
