S-Atenolol

Description

S-Atenolol is a beta-blocker that works on the heart and blood vessels. It is used to treat high blood pressure and chest pain. S-Atenolol causes blood vessels to relax resulting in an improved blood flow to the heart. As a result, the pressure at which blood is pumped out of the heart is reduced. It also slows down the activity of your heart allowing your heart to beat slower and less forcefully. S-Atenolol is used to prevent migraine headaches. The actions of S-Atenolol in preventing migraine headaches are not clear. Side-effects of S-Atenolol are dizziness, headache, breathing difficulty, and low blood pressure. If you feel dizzy or tired, care must be taken while driving a vehicle or operating machinery. Do not take this medicine if you are previously allergic to it. S-Atenolol can be taken with or without food. For the ease of remembering, take this medicine around the same time every day. Make sure to eat a healthy and balanced diet. Appropriate lifestyle changes like a low-fat diet, exercise, and stop smoking to feel better along with this medicine. You may have to take this medicine for the long-term. Do not stop taking this medicine unless your doctor tells you to stop.

Allergy

Avoid taking S-Atenolol if you are previously allergic to it. A serious allergic reaction to this medicine is rare. Seek immediate medical attention if you notice any symptoms of allergic reactions such as skin rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, breathing difficulties, etc.

Heart block greater than first degree

There are electrical signals that control the heartbeat. These signals tell your heart muscle to contract and pump blood correctly. Heart block occurs when these signals are slowed down. Heart block is named first-, second-, or third-degree. First-degree heart block is the least severe, second-degree heart block is severe and can often progress to third-degree heart block, the most severe form. S-Atenolol is not recommended to treat second or third-degree heart block that requires emergency attention.

Cardiogenic shock

Cardiogenic shock is a condition in which the heart is unable to pump enough blood to the organs. S-Atenolol can further reduce cardiac output (amount of blood the heart pumps out in a minute) and blood pressure, which can be harmful in patients with cardiogenic shock.

Bradycardia

Bradycardia or slow heart rate occurs when your heart beats less than 60 times per minute. S-Atenolol is not recommended to treat a slow heart rate.

Hyperthyroidism

Sometimes S-Atenolol is used to control symptoms like a fast or irregular heartbeat, anxiety, heat intolerance, or shivering in patients with increased thyroid levels.
