Dosage Of Trandolapril And Verapamil

The combination of trandolapril and verapamil comes as a tablet to take by mouth. It is usually taken once a day. The tablet should be swallowed whole. Do not chew, divide, or crush the tablets. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take trandolapril and verapamil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The combination of trandolapril and verapamil controls high blood pressure but does not cure it. Continue to take trandolapril and verapamil even if you feel well. Do not stop taking trandolapril and verapamil without talking to your doctor.


Keep all appointments with your doctor and the laboratory. Your blood pressure should be checked regularly to determine your response to trandolapril and verapamil.

Your doctor may ask you to check your pulse (heart rate) daily and will tell you how fast it should be. If your pulse is slower than it should be, call your doctor for directions on taking trandolapril and verapamil that day. Ask your doctor or pharmacist to teach you how to check your pulse.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
