this is a great question to ask your pharmacist and a great reason why you should always have your personal medication list on you so we can check for any interactions. you cannot take pepcid complete if you are taking atenolol. the calcium component in pepcid complete can prevent the atenolol from getting into your bloodstream thus preventing it from working and may cause fluctuations in your blood pressure. i would need to find out a bit more about why you need to take the pepcid complete -- especially what exactly are your symptoms and how frequently they are. you may be able to take regular pepcid instead. i encourage you to talk to your pharmacist for further assistance.
can i take pepcid complete if i am taking the beta-blocker atenolol?
