Drug and food interactions

Moderate

mitotane food

Applies to: Lysodren (mitotane)

High fat food significantly enhances the absorption of mitotane.

It is best to avoid or limit the consumption of alcohol, as it can increase drowsiness or other nervous system side effects of mitotane. You should also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
