What is Tenormin used for?

Tenormin is used to treat high blood pressure, which is also known as hypertension. If someone has high blood pressure, it means that their heart is working harder than it should to pump blood around the body. If this continues for a long time, the heart and arteries may not function properly. This could result in damaged blood vessels of the brain, heart, and kidneys which could result in a stroke, heart failure, or kidney failure.

It is also used to treat angina and chest pain, and has been shown to improve survival rates after a heart attack by decreasing the severity of the heart attack.

You can buy Tenormin (Atenolol) online at My Drug Center. We have the Tenormin generic, called Atenolol, available for purchase as well.


How does Tenormin work?

Tenormin is an oral medication containing the active ingredient called Atenolol. Atenolol belongs to a class of medication known as beta blockers. Beta receptors are found on cells in the heart, and when adrenaline activates a beta receptor, blood pressure and heart rate go up. Beta blockers prevent adrenaline from affecting beta receptors in your blood vessels and heart, which allows the heart and vessels to relax. The Atenolol dosage in the medication also helps decrease the heart’s demand for oxygen. As a result, blood pressure is lowered and chest pain is reduced.

Before taking Tenormin or the Atenolol generic, read all the instructions and paper work that given to you by your pharmacist. Take your Tenormin dosage orally once a day. Make sure you take it at the same time each day to create a routine for yourself and to ensure an even spread of the Atenolol dosage in your system. This medication should be taken on a regular basis to have optimal results. The Tenormin dosage that you take will depend on your condition and your age. Take this drug exactly as prescribed by your doctor. Do not change or increase your dose. You should continue taking this medication even if you feel well.


Tenormin may contain medical and non medical ingredients that could cause an allergic reaction. Consult with your doctor about any known allergies before taking Tenoretic. Speak with your doctor about any known medical conditions especially those relating to heart rhythm problems, respiratory problems, blood circulation, kidney disease, heart failure, serious allergic reactions including those needing treatment with epinephrine, or any muscle disease (myasthenia gravis).

While taking this medication, you may feel dizzy, drowsy or experience blurred vision. Avoid driving a vehicle or operating heavy machinery until you feel it is safe. Alcohol and Cannabis can exasperate these side effects. Additionally you can speak with your doctor about acceptable limits for these substances while taking Tenormin.

Side Effects

Common Tenormin side effects include:

Cold hands and feet, constipation, diarrhea, dizziness, headache, reduced sex drive or impotence, shortness of breath, unexplained tiredness, leg pain, and blood pressure that’s lower than usual

If any side effects of Atenolol become unmanageable speak with your doctor or pharmacist for help in managing any side effects. For any serious side effects that occur speak with your doctor right away for further treatment options.


What is Tenormin?

Tenormin is a prescription medication; it comes in tablet form for oral administration. A valid prescription is required to obtain this medication. Tenormin can be purchased as the brand-name medication, or as its generic alternative, in two strengths of either 50 or 100mg. Each tablet contains the fixed amount of atenolol. 


Who makes Tenormin?

Tenormin, the brand-name medication, is manufactured by AstraZeneca, a British-Swedish multinational pharmaceutical and biopharmaceutical company. It was first made available in the United States in August of 1981; and years later in 2017, it was the 36th most commonly prescribed medication to patients in the United States.


What is Atenolol?

Atenolol is the active ingredient found inside Tenormin; it is responsible for the therapeutic effects and benefits of the medication.  Atenolol is a cardioselective beta blocker which is metabolized in the liver and excreted through the kidneys with an average half-life of 6-7 hours.


What is Atenolol used for?

Atenolol, when in the form of Tenormin, is prescribed to adult patients for angina and hypertension. Using atenolol (Tenormin) can help alleviate angina and lower high blood pressure; this may help resolve consequential symptoms, such as shortness of breath, increased heart rate, and further health complications like heart attack or stroke. Additionally, atenolol (Tenormin) may be prescribed to a patient who has recently suffered a heart attack. Using atenolol after having a heart attack may help reduce the risk of reoccurrence (if reoccurrence does occur, severity may be reduced), irregular heart rhythms, angina, and can even help reduce the risk of mortality following the heart attack.


How does Atenolol work?

Atenolol works by blocking the receptors in the heart, called beta-1-adrenergic receptors, from certain hormones called epinephrine (also known as adrenaline). This affects the nerve impulses which results in the heart decreasing its work load; this means it will now beat slower and blood pressure will lower, allowing more oxygen and blood to flow to the heart and reducing symptoms and risks.


How long does Atenolol last?

The effects of atenolol will generally persist for at least 24 hours following your last dose; that is roughly one full day that the effects should stay consistent for. However, the exact amount of time may vary between each individual.


When is the best time to take Atenolol morning or night?

Your doctor will let you know when to take atenolol for the best results; follow only the directions given to you by your doctor. Atenolol may cause dizziness; your doctor may recommend taking your dose before bed to help avoid this side effect. If you do not become dizzy after your first dose, you may take your dose in the morning, if you prefer, if your doctor doesn’t specify otherwise. If you take multiple doses per day; you should allow at least 10-11 hours in between each dose.


How long does it take for Atenolol to work?

The exact amount of time may vary between each individual as many factors determine the answer. However, you can expect the drug to begin working within 3 hours into treatment; though you may not notice the effects of the medication. The full effect may be seen around 2 weeks into treatment, although, since hypertension doesn’t pose many symptoms, you may not be able to recognize the medication is working. To help ensure the medication is working properly, follow all directions on how to take atenolol, as directed by your doctor. They may also go over how much atenolol is too much and how to stop taking atenolol safely; it is very important to fully understand all the information provided to you by your doctor in regards to properly taking and stopping this medication.


How long does it take Atenolol to lower heart rate?

Similar to the previous answer, it should begin to lower your heart rate (and blood pressure) only a few hours into treatment and should persist for at least 24 hours following your last dose. If you have any further questions, you may need to speak with your health care provider.


How long does Atenolol take to work for anxiety?

Anxiety is a condition which a beta-blocker, such as atenolol, is sometimes used for. You will likely notice an improvement after only one dose; because the medication begins to lower your heart rate right away, following only your first dose, you may notice yourself feeling more relaxed. However, the exact amount of time will vary between each individual.


How long does Atenolol stay in your system?

Atenolol has a half life of about 6-7 hours; a medication will take roughly 5 half-lives to clear out of the system. With that being said; atenolol will likely remain in the system for up to 35 hours (just under 1.5 days) following your last dose.


What are the side effects of Atenolol 25 mg?
