Hi @lizzy123, There is a discussion on Metoprolol where member may be able to share their experience but I would think that talking with your doctor would be your best option.

-- Metoprolol: https://connect.mayoclinic.org/discussion/metoprolol-6/

I took Lisinopril for blood pressure for many years until I participated in a Mayo heart study and they changed my diagnosis a little and replaced the Lisinopril with Spironolactone.

Have you discussed your concern that adding the new drug worries you?

Hi Lizzy!
I take both Lisinopril and Metoprolol for high blood pressure too. I also take Clonidine and Amlodipine for high blood pressure. They have all worked very well for me with no side effects and my blood pressure is always regular such as 115 to 120. However, everyone is different. For instance, I can't take Tylonel. It bothers me. Everyone else takes it and is just fine. I would suggest that you talk to your Doctor about your concerns. He knows your medical history and your body's reactions to medications. You also might want to look up the side effects of Lisinopril and Metoprolol on the Mayo Clinic. (You can trust what the Mayo Clinic states as opposed to some unknown website.)
Good luck!
