Can anxiety medication cause nightmares?

It depends: It depends what kind of medication you are taking. Seroquel (quetiapine) is sometimes used to treat anxiety and it is known to cause bizarre dreams and nightmares. Talk to your doctor about what you are experiencing and have your medications evaluated. Some nightmares might be due to anxiety and more medication might be needed instead of less. More information is needed to make the right decision.

Rarely: This is an unusual response to an anxiety medication. So it makes sense to consider other possible causes. If something is causing anxiety, that could lead to nightmares. Or any other medication change?
