Use
What is atenolol used for?
Atenolol belongs to the class of beta blocking drugs (beta blocker). These drugs work by inhibiting the action of epinephrine which can increase blood pressure.
Therefore, the main function of atenolol is to lower high blood pressure (hypertension) and treat angina, or chest pain. Lowering high blood pressure can help prevent strokes, heart attacks, and kidney disorders.
This drug may also work to increase the chances of survival after having a heart attack and other heart diseases. These beta blocker drugs can reduce heart rate, blood pressure, and pressure on the heart.
Atenolol may also be useful in treating irregular heartbeats (arrhythmias), heart failure, hangover symptoms and preventing migraine headaches.
This drug is a prescription drug, so you can only get it if you buy atenolol at a pharmacy with a doctor's prescription. Do not carelessly buy prescription drugs without the doctor's knowledge because you do not necessarily understand well the dosage according to your health condition.
How to use atenolol?
There are several things you should pay attention to when using this drug, including:
Avoid drinking apple juice and orange juice
Apple juice and orange juice can inhibit the absorption of this drug. The best way to get the best benefit from using this medication is to avoid drinking apple or orange juice for four hours after taking atenolol.
Take medicine according to the rules of use
You can take atenolol with or without food as directed by your doctor, usually 1-2 times a day. For dosage, the doctor will adjust the amount according to your health condition.
In order for it to work effectively, this medicine must be taken regularly. To help you remember, take it at the same time each day.
Don't stop the dose
Even though you feel healthy and better, do not stop taking this medicine without your doctor's permission. This is because most people with high blood pressure don't feel pain and just let the disease go away. Medicines should not be used to treat chest pain when it occurs.
Use other medications (such as nitroglycerin placed under the tongue) to relieve chest pain as directed by your doctor.
It may take 1-2 weeks before you fully benefit from using atenolol. Tell the doctor if the condition does not improve or gets worse (for example, if blood pressure remains high or increases, if chest pain occurs more frequently).
How to store atenolol?
Store the medicine at room temperature, away from light and moisture. Do not store in the bathroom and freeze medication. Medicines under different brands may have different storage methods.
Check the product box for instructions on how to store it, or ask a pharmacist. Do not open the atenolol bottle when it is not being used. Close the atenolol bottle again after use. Stay away from children and pets.
Do not flush the medicine in the toilet or throw it into the drain if not instructed. Properly discard this product if it is past the deadline or is no longer needed. Consult a pharmacist for more in-depth details on how to safely discard the product.

Can food or alcohol interact with atenolol?
Certain drugs cannot be used with meals or when eating certain foods because drug interactions can occur. Consuming alcohol or tobacco with certain drugs can also cause interactions to occur. Discuss with a healthcare professional about using drugs with food, alcohol, or tobacco.
When taking atenolol, try not to take it with orange juice because the interactions that occur can cause the effectiveness of the drug to decrease. Meanwhile, the interactions that occur between atenolol and multivitamins that contain minerals can reduce the effect of atenolol on the body.

- Diabetes
- Hyperthyroidism (overactive thyroid)
- Hypoglycemia (low blood sugar). It may mask some of the signs and symptoms of this disease, such as a fast heartbeat.
- Kidney illness. Use with care. The effect may increase due to the slower disposal of the drug from the body.

Not everyone who uses atenolol can overdose, but you should always be careful what dosage you use if you want to use atenolol long-term.
What should I do if I miss a dose?
If you forget a dose of atenolol, take it as soon as possible. However, when it is near the time of the next dose, skip the missed dose and return to the usual dosing schedule. Don't double the dose.
