Can Lexapro Be Taken While On Metoprolol?

my 29 year old son has A-fib and takes Lopressor to manage it. He has been on Zoloft for 10 years to cope with anxiety from A-fib episodes, and is now being switched to Lexapro. I read that metoprolol can interact with Lexapro, and that Lexapro can cause long Q-T. I am very concerned. Is he in any danger?

Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.

Regarding your concern, I would agree with you on the fact that Lexapro can cause QT prolongation. For this reason, it is important performing periodically a resting ECG to investigate for QT prolongation. Regarding Metoprolol, it is OK to take it while on Lexapro.

Hope you will find this answer helpful!

Wishing good health,
Dr. Iliri
