Tenormin (atenolol) is a brand-name beta-blocker that is prescribed for the treatment of hypertension, angina pectoris, and post-myocardial infarction in certain cases. Tenormin tablets of 25 mg, 50 mg, and 100 mg help decrease heart rate and its workload.

Prescription required: A valid prescription is necessary before you make a purchase. Use only the strength and dose prescribed by your physician.

What Is Tenormin (Atenolol)?

Atenolol is another name for the medicine known as Tenormin, which is a beta-blocker and acts selectively on beta-1 receptors. The primary mode of action of the drug includes decreasing the heart rate and force of contraction.

If you are researching what atenolol is, it is a prescription medicine used for selected cardiovascular conditions. Tenormin uses include hypertension, angina, and treatment of certain patients following a heart attack.

The correct dose is determined individually depending on the diagnosis, heart rate, blood pressure, renal function, and effectiveness of therapy.

What Does Atenolol Treat? (Uses)

Common Tenormin uses include:

➧ High blood pressure: Helps decrease blood pressure and prevents complications related to high blood pressure.

➧ Angina: Helps prevent or lessen chest pain caused by lack of blood supply to the heart muscle.

➧ Following a heart attack: Can be prescribed to clinically stable individuals as a treatment after a heart attack.

Atenolol can be used as monotherapy or in combination with other medications. It cannot be used as a replacement for emergency treatment in case of a heart attack.

Choosing Your Atenolol Strength: 25 mg vs 50 mg vs 100 mg

The right dose of atenolol should be determined according to the medical problem that the patient is suffering from, as well as according to individual characteristics of the patient’s health. For example, for high blood pressure, the recommended dose of atenolol is 50 mg per day, and sometimes even 100 mg per day.

Atenolol 25 mg — The Typical Starting Dose

If you require a lower dosage to start with, then Atenolol 25 mg is the right product. It is not the typical initial dose for all hypertensive patients.

If you have a prescription for 25 mg of Atenolol, check out what Tenormin or generic versions of Atenolol are offered at RxCroma.

Atenolol 50 mg — The Standard Maintenance Dose

Atenolol 50 mg is the recommended initial dose for adults suffering from hypertension. The physician can change the dose depending on your blood pressure, heart rate, and reaction to the drug.

Atenolol 100 mg — The Maximum Common Dose

Atenolol 100 mg is generally prescribed when a lower dose fails to provide sufficient control. It is a commonly used upper daily dose for hypertension. The appropriate maximum dose depends on the indication and the patient’s kidney function.

Never increase your dose without proper medical guidance.

How to Take Tenormin (Atenolol)

Take Tenormin strictly as directed. The drug can be taken either once a day or following some other prescription regimen. Your healthcare provider might also check your blood pressure, heart rate, and renal function.

Best Time to Take Atenolol — Morning or Night?

Atenolol can normally be taken in the morning, or alternatively at some other specific time, based on your prescription. You should follow the prescribed regimen and consult your pharmacist for clarification if required.

Taking Atenolol With or Without Food

Atenolol can generally be taken with or without food. Taking the drug consistently in relation to meals may help maintain a proper routine. Follow what your prescription specifies and ask your pharmacist if you are unsure when to take it.

Tenormin Ingredients

The main active ingredient in Tenormin is atenolol, which falls under the category of beta blockers. The medication comes in tablets of 25 mg, 50 mg, and 100 mg.

Inert components may vary among different manufacturers. You should refer to the medication label or consult your pharmacist in case of any allergies to certain components.

Important: Never Stop Atenolol Suddenly

Is atenolol discontinuation possible without any medical consultation? Definitely not! 

Discontinuing atenolol treatment abruptly could result in angina deterioration and the possibility of life-threatening complications such as a heart attack, especially in patients suffering from coronary artery disease.

If you decide to stop using atenolol, a careful decrease in dose is expected and supervised by your doctor. Avoid changing your dose or stopping medication without consulting with your physician regardless of your feeling good.

In case of increasing chest pain after dose reduction or missing at least one pill, contact your physician right away. If chest pain becomes unbearable, please call the emergency service.

Atenolol Side Effects

Atenolol can cause side effects, although not every patient experiences them.

Common Side Effects — Including Fatigue

Common side effects associated with atenolol include:

  • Tiredness or fatigue

  • Dizziness

  • Slow heartbeat

  • Cold hands or cold feet

  • Nausea or diarrhea

Atenolol and fatigue: Atenolol slows down the heartbeat and decreases the workload on the heart. Some patients experience fatigue as a result of the slowing of the heart rate and the workload.

Consult your doctor if you are experiencing persistent fatigue that is affecting your daily life.

Serious Side Effects — Seek Help Immediately

If any of the following occur, consult your doctor right away:

  • Very slow pulse rate that is associated with dizziness, fainting, or weakness

  • Difficulty breathing or wheezing

  • New or aggravated chest pain

  • Indications that heart failure is getting worse, such as breathlessness, edema, or quick weight gain

  • Severe allergic reaction, which includes swelling of the face or mouth area

Atenolol can obscure some signs of hypoglycemia, especially a fast heartbeat. Those with diabetes should speak with their medical practitioner about blood glucose testing.

Atenolol Interactions — What to Avoid

Inform your medical practitioner about all prescription medicines, over-the-counter products, and supplements you use.

Atenolol and Alcohol

Both atenolol and alcohol can raise the likelihood of experiencing dizzy spells, light-headedness, or having low blood pressure. You should cut down on the consumption of alcohol until you are familiar with the effect of the drug on you.

Other Drug Interactions

Important potential drug interactions for atenolol include:

➧ Other antihypertensive drugs: Increase the likelihood of hypotension or slowed heart rate.

➧ Verapamil or diltiazem: Will slow down the heart rate even more along with atenolol.

➧ Digitalis and some antiarrhythmics: The chance of developing bradycardia or other heart arrhythmias increases.

➧ Clonidine: Changes in any of these drugs have to be made carefully and under medical supervision.

➧ Medications for diabetes: May mask hypoglycemic symptoms caused by atenolol.

➧ Some nonsteroidal anti-inflammatory drugs (NSAIDs): May impair the effects of atenolol on blood pressure.

Do not alter your therapy without consulting a medical practitioner.

Storage Instructions

Follow the instructions provided on the product label when storing Tenormin. The guidelines include storing the medication in a tightly closed container, ensuring that it is not exposed to high temperature or moisture. Keep Tenormin away from children and pets.
