Atenolol is a beta-selective (cardioselective) adrenoceptor antagonist that has no partial agonist or membrane stabilizing properties. Its action profile is most similar to that of metoprolol, with the exception that it has some membrane stabilizing function. Atenolol has been extensively researched and shown to be effective in the treatment of hypertension as well as the prevention of angina. Because of its limited dose response spectrum, it does not require highly individualized dose titration.

Atenolol Usage Guidelines
Adults are able to take atenolol. It is also often recommended for infants and children.
It is not enough for everybody. Before taking atenolol, inform your doctor if you have any of the following conditions to make sure it’s healthy for you:
allergic reaction to atenolol
severe blood pressure issues in your limbs (such as Raynaud’s phenomenon), which can cause tingling, paleness, or blueness in your fingers and toes
If there is so much acid in the blood, you have metabolic acidosis, which can lead to respiratory failure or asthma.
When to take it and how
Atenolol is normally taken once or twice a day.
Since atenolol will make you dizzy, your doctor can urge you to take your first dose before bedtime when you first start taking it.
If you do not feel dizzy after the first injection, you should take your medication in the morning.
You’ll normally take one dose in the morning and one dose in the evening if you’re taking atenolol twice a day.
It’s best to wait 10 to 12 hours between doses if possible.
If you have heart failure, do not abruptly stop taking atenolol. This will aggravate the disease. COVID-19 Vaccine Testing ,Safety, Side Effects
Chat with the doctor if you wish to consider taking your medication. They could suggest steadily lowering the dosage over a few weeks.
The amount you take is determined by the reason you require atenolol.
The standard dosage for elevated blood pressure is 25mg to 50mg once a day.
The normal dosage for angina (chest pain) is 100mg once a day, or divided into two 50mg doses.
The normal dosage for abnormal heartbeats (arrhythmia) is 50mg to 100mg once a day.
The normal dosage for migraine is 25mg to 100mg twice a day. Atenolol is often used for migraines, although it isn’t specifically approved for migraine prevention.
Your child’s doctor will determine the appropriate dosage for them based on their weight and age.
How to take
Since atenolol seldom causes stomach upset, you should take it with or without food. It’s better if you do the same thing every day.
With a glass of water, swallow the tablets together.
Some products have a score line to help you cut the tablet in half if it’s tough to chew. Check the brand’s detail leaflet to see if anything is possible.
If you’re taking atenolol as a powder, it’ll come with a plastic syringe or spoon to make sure you get the right dose.
If you don’t have one, you should get one from your pharmacist. A kitchen teaspoon would not provide you with the correct quantity of medication.
More than 1 in 100 people experience these typical side effects. They’re normally mild and only last a few days.
If these side effects affect you or last more than a few days, talk to the doctor or pharmacist:
cold fingers or toes, sleepy, sore, or dizzy
feeling unwell (nausea)
Breastfeeding and pregnancy
In most cases, atenolol is not prescribed during breastfeeding.
Speak to the doctor about the advantages and risks of taking atenolol whether you’re planning to get pregnant or are currently pregnant.
Some medications could be more suitable for you. Labetalol is a similar drug that is often used for elevated blood pressure during breastfeeding.
