How Lexapro may interact with other medicines

To avoid harmful interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbal supplements you are taking. To find out how this drug might interact with something else you’re taking, talk to your doctor or pharmacist.

Medications containing escitalopram or citalopram should not be used with Lexapro. This includes Celexa. Certain medications may increase the chances of side effects, and increased monitoring may be necessary. Check with your pharmacist or doctor if you are on any of these medications.

Examples of drugs that can increase bleeding include:

  • ibuprofen (Advil, Motrin)
  • naproxen (Aleve, Naprosyn)
