How does this medication work? What will it do for me?
Atenolol belongs to a class of medications called beta-blockers. It is used to lower high blood pressure and to prevent the symptoms of angina (chest pain). It works by reducing the demands put on the heart.
Atenolol is often used in combination with other high blood pressure medications such as diuretics (water pills) when the use of one medication by itself is not enough to control blood pressure.

How should I use this medication?
The recommended adult dose of atenolol ranges from 50 mg to 100 mg once daily depending on circumstances. If you have reduced kidney function you may need much lower doses. The full effect of the medication is usually reached within 1 to 2 weeks. If blood pressure is not reduced sufficiently after this time, your doctor may increase the dose of the medication or add another blood pressure-lowering medication. If satisfactory results are not seen within 1 week for treatment of angina, your doctor may increase the dose of atenolol.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
