Question/Comment:
I am on Benicar 40mg and verapamil 360mg. My doctor told me to take Centrum which has iron (18mg) in it. Do you think there is any interactions for Benicar/Verapamil with Centrum?

iGuard Answer/Reply:
The iGuard Drug Interaction System does not list an interaction between Centrum and the two blood pressure medications Benicar or Verapamil. The iron does not interact with either medication. Please be sure to list all of your medications and supplements in your iGuard profile to have them checked for interactions listed in our system.

what side effects would occur taking verapamil 188 mg one day after taking lopressor? I experienced shortness of breath, fatigue, rapid pulse and a migraine. Could it be overmedication or just the change in medications? 60 yr old male
