Atenolol Teva – Atenolol uses, dose and side effects


25 mg, 50 mg, and 100 mg film-coated tablets 

1. What Atenolol Teva is and what it is used for

Atenolol Teva contains the active substance atenolol, which is a so-called heart-selective beta-blocker. This means that the drug mainly affects the heart and circulation, while other organs are affected very little. Atenolol Teva reduces the effects of heart-affecting substances (so-called stress hormones) that are formed in connection with mental tension and physical exertion. This causes the heart to beat more slowly ( heart rate decreases) and the heart to pump out less blood per minute. This lowers blood pressure and prevents the onset of angina (which is due to overexertion of the heart muscle).

Atenolol Teva is used to treat high blood pressure, angina ( angina pectoris ), to reduce the risk of heart attack, to provide regular cardiac activity, and to protect the heart during and after a heart attack.

Atenolol contained in Atenolol Teva may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.
