Tenormin (Atenolol)

What is Tenormin? Tenormin, also called atenolol, is part of a group of medications called beta blockers and is used to control anxiety in adults, young adults, and teenagers. Tenormin can also be prescribed as part of a treatment plan for heart and blood pressure ailments or to help control the symptoms of alcohol withdrawal. Tenormin comes in a tablet and is usually taken two or three times per day. Take Tenormin exactly as directed.


Important Information Before Use:

  • Tenormin can help control the rapid heart rate and high blood pressure that accompanies anxiety but cannot cure this condition.
  • It is very important to take Tenormin as scheduled; do not stop taking this medication abruptly.
  • If you have or have ever had a heart attack or heart disease, asthma, or other lung problem, diabetes, allergies, thyroid disease, or kidney disease, you should talk to your doctor about these conditions before you take Tenormin.
  • Tenormin may interact with other medications or supplements, including antihistamines, cough and cold medications, blood pressure medications, pain relievers, and more. If you are taking any other prescription drugs or supplements, you should check with your doctor or pharmacist before taking Tenormin.

Important Information During Use:

  • Let your doctor know right away if you are pregnant or become pregnant while taking Tenormin; a different medication may be used to manage your anxiety during pregnancy.
  • Tenormin can increase allergic reactions; if you already have allergies, taking Tenormin can make your reactions more severe.
  • If you are having any type of surgery, including dental surgery, tell your doctor, dentist, or surgeon that you are taking Tenormin.
  • Tenormin overdose is a medical emergency and should be treated right away. Symptoms of Tenormin overdose include a slowed heartbeat, extreme weakness, dizziness, fainting, and difficulty breathing.
  • If you experience serious or severe side effects from Tenormin, you should call your doctor immediately.
