Atenolol (Definition)

Atenolol is a relatively long-acting (24 hours) beta-blocker. Beta-blockers as a group of medications calm or slow the heart rate down. They stop the swings in hr from stress or nerves. If someone is on a good dose of a beta-blocker and are startled, the medication suppresses the pounding of your heart. It also won't allow the hr to climb with exercise. It's used to ...Read more

On spironolactone 50 mg and atenolol 100 mg for blood pressure , I am trying to do HIIT, I feel like passing out when working out what can I do?

On spironolactone 50 mg and atenolol 100 mg for blood pressure , I am trying to do HIIT, I feel like passing out when working out what can I do?

Passing out: One of the reasons you have a problem working out is that you are on atenolol (A). It works by slowing your heart rate and if you exercise, your pulse may not be able to increase because of A. Ask your physician if you can stop the A safely. If you can, your problem with exercise may be resolved. Good luck. ...Read more

What are the chances of organ damage due to overdose on atenolol. 6 tablets 100 mg?

What are the chances of organ damage due to overdose on atenolol. 6 tablets 100 mg?

Probably low: The chances of organ damage from 600mg of atenolol is probably low, in an adult of normal size and decent health. Reports of overdoses of atenolol mention doses in the ranges of 1000mg to 5000mg. The underlying health of the patient, such as any coexisting medical problems (kidney disease or other diseases) can make a difference if an accidental overdose is taken. ...Read more

I'm not sure but i think i may have accidentally took an extra 100 mg atenolol several hours apart. Will i be ok?

I'm not sure but i think i may have accidentally took an extra 100 mg atenolol several hours apart. Will i be ok?

Most Probably- Yes: Watch for anxiety, nervousness headache, unusual tiredness and even trouble sleeping. If you experience worsening difficulty breathing, chest pain, change in vision, fast heart beats or tingling/numbness/ cold hands /feet go to er. Atenolol last in the system for about 6-7 hours. Any of the above symptoms should be improving over time. Drink plenty of water to help eliminate the drug. Take care. ...Read more

Is it less risky to double dose altenolol or miss a dose? I can't recall if i took 100 mg dose of atenolol 6 hrs ago. Should i take a dose now or not?

Is it less risky to double dose altenolol or miss a dose? I can't recall if i took 100 mg dose of atenolol 6 hrs ago. Should i take a dose now or not?

Skip the dose: It looks like you asked this question awhile ago, so this may not be relevant anymore, but in your case, at 6 hours, i would say to just skip the dose rather than possibly double up on it. I would recommend just checking your BP every hour or two and make sure it's not too high, then resume your normal dosing schedule. If it is too high, call your doctor. ...Read more

I fall into the upper pre-hypertension or low hypertension level. Is 100 mg losartan and 25 mg atenolol a good combination to treat?

One drug: It sounds a bit excessive to start 2 drugs for such a mild blood pressure elevation. Usually you start with just one drug and the class of drug you start with is determined by several other factors. Hope this helps. ...Read more

Is 12.5 mg atenolol bid a good dose to keep a heart rate down below 100 beats/min at night?

Is 12.5 mg atenolol bid a good dose to keep a heart rate down below 100 beats/min at night?

Starting dose: Total of 25 mg in divided doses is a good starting dose. Can go up to 100mg a day. Are you having dizziness after atenolol started? I like the combination with a diuretic. Remember that lifestyle changes like weight reduction, exercise, low sodium/high potassium and magnesium/low fat diet, stop smoking and stress reduction technique can reduce your BP too. If hr high you may need to increase dose. ...Read more
