Your healthcare professional may have to adjust your dose or watch you more closely if you take the following medications:

Is There Anything Else I Need to Know About Taking Zyprexa?

Dizziness (and sometimes fainting) caused by a drop in blood pressure may occur with Zyprexa, especially when you first start taking Zyprexa or when the dose is increased.

Zyprexa may impair judgment, thinking, or motor skills. You should be careful when operating machinery, including automobiles, until you know how Zyprexa affects you.

It is important to avoid overheating and dehydration while taking Zyprexa, because Zyprexa use may make it harder to lower your body temperature.
