Atenolol
About Atenolol
Atenolol is used to treat high blood pressure (hypertension), irregular heartbeats (arrhythmias), and chest pain with chest tightness (angina pectoris). High blood pressure increases the heart's workload, and if it continues for a long time, the heart and blood vessels (arteries) may not function properly.
Atenolol contains atenolol, which primarily helps relax our blood vessels by blocking the action of certain natural substances in your body.
Sometimes, you may experience headaches, cold hands/feet, diarrhoea, feeling sick (nausea), tiredness, aching muscles, a depressed mood, and dizziness. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist, contact your doctor.
Don't stop taking Atenolol without talking to your doctor first. Stopping Atenolol gradually may cause heart rhythm and blood pressure changes and cause chest pain or a heart attack. Inform your doctor If you are a pregnant woman or nursing mother. Atenolol is not recommended for children below 12 years.

Patients Concern
Disease/Condition Glossary
Hypertension: The blood exerts increased pressure on the walls of blood vessels leading to hypertension. High blood pressure is expressed as systolic/diastolic pressure. Systolic pressure is the pressure in the arteries when the heart beats or pumps out blood. Diastolic pressure is the pressure in the arteries between the heartbeats. Blood pressure is measured in millimetres of mercury (mmHg) by a blood pressure monitor called a sphygmomanometer. Some of the symptoms are headache, dizziness, nosebleeds, altered vision, chest pain, weakness, and shortness of breath. However, most of the time, the signs and symptoms of hypertension are none.
Arrhythmia: It is a problem associated with the rate of rhythm at which the heart beats. Generally, in this condition, the heart beats too fast, too slow, or irregularly. It can lead to severe heart damage. A cardiac arrhythmia occurs when there are abnormal electrical signals in the heart. When the heart beats too fast, it is known as tachycardia, and if it is too slow, it is called bradycardia. Treatment of arrhythmia includes drugs, medical procedures, implantable devices and sometimes surgery.
